Greenhouse planting schedule
Greenhouse gardening: When is the best time to start planting? | Ferrellgas
Seed catalogs and garden magazines are full of the promise of spring and summer, especially this time of the year. And if you’ve dropped by your local hardware or grocery store recently, you probably saw gardening tools and seed packets on display as soon as you walked in the door.
Whether you’re a part-time gardener with one greenhouse or a fulltime grower with dozens, we know your green thumb is itching to dig into the soil and get those seeds in the ground. But when is the best time to start planting?
Getting started
As any gardener knows, there’s a lot of prep work that must happen before you can begin planting. Before starting seeds, it’s important to disinfect shelves, benches, pots, and trays. While the warm, humid atmosphere of your greenhouse makes it the ideal environment to start seedlings, it’s also the perfect climate for fungi, algae, gnats, and other pests to grow.
Regulating the humidity in your greenhouse with proper ventilation is one way to fight against these disease-causing organisms throughout the year.
As you prepare for another growing season, you’ll also want to keep soil health in mind. If you’re a producer who plants one crop continuously without rotation and are experiencing lower yields than you’d like to see, you may want to consider crop rotation.
When the same crop is planted year after year, the soil can have a buildup of diseases, such as bacterial wilt, bacterial canker, fusarium, and verticillium wilts. These can be remedied by rotating crops and treating the soil with organic or inorganic fertilizers to replenish soil fertility. (For example, you could grow onions or cauliflower this year if you grew tomatoes in the same spot last year.)
You can also combat diseased soil by bringing in fresh, quality soil from outside your greenhouse. While this is easier to do if you’ve grown in pots, it can still be done in larger garden beds.
Although a clean greenhouse and healthy soil are two very important pieces of the puzzle, your greenhouse wouldn’t be much to boast about without plants. As you begin thinking about what seeds you’ll sow and when, here are a few helpful tips to keep in mind:
- Be seed savvy. Start by sorting your seed packets into categories: cool season plants vs. warm season plants and those that grow best when directly sown into the soil vs. those that grow best when started indoors.
- Create a calendar. Find the average last frost date in your area (you can do this by searching your ZIP code online) and count backward six to eight weeks, depending on the directions on the back of your seed packet.
- Go soilless. Of course, you’ll need soil for your plants to grow, but if you’re starting seeds in pots or trays be sure to choose a soil mix designed for seed starting. Soilless mixes are designed for better drainage and to fight against soil-borne diseases. Regular potting soil or plain garden soil are often too heavy, so it’s recommended that you use a compost-based mix.
- Don’t forget the labels. When little green seedlings are peeking up from fresh dirt, they all look alike. It will be difficult to tell one sprouting seed from the next, so make sure to label each kind. That way you can follow the proper guidelines each plant needs for water, sunlight, and fertilizer.
Planting seeds
The good news about greenhouses is that they allow you to jumpstart the growing season, and using propane heaters to keep them warm, they help protect against late frosts to produce healthy seedlings. The broad rule of thumb in the northern region of the United States is not to plant in a greenhouse until after Valentine’s Day due to low light conditions in the winter months.
Still, experts often recommend waiting to plant early spring vegetables – like lettuce, peas, and spinach – until March and April. Warm-season veggies like these are not frost tolerant and need the added protection a greenhouse has to offer.
Because seeds take longer to germinate and plants grow more slowly when the air and soil temperatures are cool, it’s also recommended that you keep your greenhouse between 75 to 85 degrees in the day and 60 to 75 degrees in the night. Doing so keeps plants healthy and uniform.
Beyond season extension, greenhouses also provide other advantages. Growing in one ensures that crops are protected from the elements and not affected by wind, rain, or hail. And, as long as ideal growing conditions are maintained, yields are often higher for crops grown in greenhouses.
Heating a greenhouse
After you’ve gone to all the work of improving the health of your soil and planting your seeds, the last thing you want is to have a late frost wipe out all your efforts. One of the most popular ways to show the frost who’s boss is to heat your greenhouse using a propane heating system.
Propane is a clean-burning fuel chosen by farmers because it is environmentally friendly and cost effective.
Growers rely on propane-powered combined heat and power (CHP) systems because they can operate at 70-80 percent efficiency while using less fuel to produce each unit of output. For you and your greenhouse, that means increased productivity and decreased environmental impact. So even when the weather in the early spring months is chilly and unpredictable, you can protect your plants against damage.
The most common types of greenhouse heating systems can be classified into two groups: central and local. A central heating system typically uses a boiler to generate heat in one spot. The warm air is then blown into the greenhouse using a forced air system. The benefit of this is that heat is evenly distributed throughout the entire structure.
Local heating systems are generally placed in the section of the greenhouse they are responsible for heating. Using radiant heat or bottom heat boilers, these systems offer more localized, concentrated heat, which in turn increases efficiency.
The type of heater you choose can depend on the crop you’re growing and the amount of heat it needs to thrive. For example, for plants that require warmer soil temperatures and higher heat, bottom heat boilers are a great option because they use more direct heat to keep the root zone warm.
Finding a heating unit
Most first graders can tell you that plants need three things to grow: heat, light, and water. Because those things are so concentrated in a greenhouse, they’re what make a greenhouse an oasis for plants. However, greenhouses can be harsh, corrosive environments for anything that’s not green and growing – things like heating equipment. That’s why you’ll want to look for aluminized or stainless steel heat exchangers, as these will help extend the life of your heater in the humid atmosphere.
Here are a few additional things to consider when looking for a propane-powered heat unit:
- A thermostat to control temperature effectively and efficiently.
- Fans to help distribute heat evenly throughout the greenhouse.
- Brackets to safely mount the heater to the greenhouse structure.
- A high efficiency model. While this may cost a little more up front, it will be more efficient and cheaper to operate over time.
- A unit that provides the right amount of heat for your operation. Heater size depends on several variables: the square footage of your structure, the type of material covering it, average wind speed, and the inside growing temperature you’re aiming for.
Propane-powered heat units are among the most popular choice for greenhouse heaters, and for good reason. Because propane is a clean-burning fuel, your propane-powered greenhouse heater will require less maintenance than oil, diesel, or kerosene models. With minimal maintenance, increased efficiency, and environmentally-friendly heat, it’s no wonder growers are turning to propane to help produce their fruits and vegetables throughout the year.
Predicting heating costs
Because no tool or person can predict the weather perfectly, it’s difficult to calculate the exact amount you’ll spend heating your greenhouse. However, the USDA offers a valuable (and free) tool called Virtual Grower 3. This software program will ask you for information such as the nearest weather station (so it can calculate typical weather conditions), type of greenhouse structure, condition of the structure, type of heating system, and price of fuel.
Not only can this tool help you figure out where heat savings can be achieved, it can also predict crop growth, assist in scheduling, make real-time predictions of energy use, and show the impact of supplemental lighting on plant growth and development. It provides a virtual laboratory where you can experiment and run scenarios to help you become a more educated, equipped grower.
Then, when you’re ready to dig in and get your hands dirty, you’ll really know what you’re doing.

Greenhouse Planting Schedule - A Greenhouse Planting Calendar
By Kylie Gettleman
How do you keep your backyard greenhouse supplying food year-round? There are two fundamental factors to consider when planning your greenhouse planting schedule: temperature and day-length.
Check out our printable greenhouse planting guide here
Let’s start with understanding the importance of day-length, which is arguably the most important factor when determining your greenhouse planting schedule. If you are not using supplemental lighting, then it will be critical for you to know what average day lengths are for your area throughout the year. Where we’re located in Colorado, early February marks the time when our day length begins to reach 10 hours per day, which is generally enough daylight for seedlings to grow. And mid-November marks the time when our days drop below 10 hours and plant growth significantly slows.
Plants will continue to survive throughout the winter, but will typically enter a semi-hibernation. If you plant your winter garden early enough, plants will be nearing maturity by the end of November and you’ll be able to slowly harvest all winter long from the semi-dormant plants, even without supplemental lights.
The other consideration for your greenhouse planting schedule is the temperature inside your greenhouse, and the many micro-climates that may exist inside the greenhouse. The coldest parts of your greenhouse will typically be close to your greenhouse glazing and right next to your vents. That’s where you’ll want to place your cold-hardy vegetables throughout the winter, like spinach and kale. The warmest part of your greenhouse will typically be along the north wall where the sun reflects off and hits the plants in that vicinity. By planning your greenhouse planting schedule according to day length, managing your plant’s location based on temperature, and choosing the right crops and varieties, you’ll be able to harvest year-round vegetables.
Here is a general greenhouse planting guide (broken down by months) that we use for our location in Boulder, Colorado at about 40 degrees latitude.
February:The days are beginning to lengthen as we move towards the equinox. At Ceres headquarters in Boulder, Colorado, February marks the time when there is now enough daylight (about 10 hours a day) to start to seed new crops without needing to use supplemental lighting.
Cold hardy kale in the greenhouse
Begin seeding your first spring round of cold tolerant crops (lettuce, kale, radishes, beets, carrots, peas, etc).
Begin seeding warm-loving, long-season vegetable crops in the greenhouse (tomatoes, peppers, eggplant, etc). These crops typically take 100-150 days to mature and they do not tolerate cold weather, so plan to give them the longest possible time in a warm growing environment while they grow and ripen their fruit. You can start these crops in your greenhouse and transplant them outside once the nighttime temperatures are consistently above 55 degrees.
Or you can keep them growing in your greenhouse all summer long and into the fall.
March/April:
Basil- a warmer season crop
Near the spring equinox, daylight lengthens and plants begin to grow more quickly in the greenhouse. Begin to seed warm-season crops with shorter days to maturity (beans, basil, cucumbers, squash).
Begin to harvest from your first round of cold-tolerant crops and continue planting cold-tolerant, quickly growing crops to replace them.
May:The lengthening days and warmer nights allow for much faster growth in your greenhouse.
You’ll likely be harvesting a lot from crops like lettuce, kale, spinach, and peas.
If you have started transplants in the greenhouse, you can now start to plant cold-tolerant transplants outside (broccoli, cauliflower, cabbage) once the night time temperatures are consistently above 45 degrees and warm-season transplants outside (tomatoes, peppers, eggplant) once the night time temperatures are consistently above 55 degrees.
This is generally a hot time for greenhouses, depending on what type of cooling systems you have. Your warm crops, like peppers, eggplant, beans, and tomatoes will be very happy in the greenhouse, but you’ll still have to watch for overheating and make sure you have proper ventilation and that you have enough humidity to keep the plants from transpiring too much and wilting. (To learn more about the relationship between temperature and humidity in your greenhouse, see our blog post about VPD).
A happy time for warmer crops in the greenhouse- eggplant
August/September:This is usually the time to start to plant your winter garden. November through January, day length shortens such that plants will grow very slowly without supplemental lighting. Your goal with a winter garden is to plant early enough that most plants are close to reaching maturity by November or December. As plant growth slows, your crops will go into a semi “hibernation” and you will be able to harvest slowly throughout the winter even without seeing very much new growth.
Before the first frost in your area is also the time to move some potted plants inside the greenhouse for the winter. Citrus, figs, peppers and tomatoes that are in pots outside can survive the winter in pots in the greenhouse. We’ve seen potted pepper plants that are over 3 years old grown this way, and are still producing fruit.
October:Days are beginning to shorten. You’ve already gotten your winter garden planted, but October can still provide enough light to start very short cycle crops (like radishes that only take 20-30 days to mature) or to start crops that you plan to harvest in the late winter/early spring, knowing they will grow very slowly throughout the winter.
Hardy vegetables like spinach, lettuce, and kale planted now will typically have time to germinate and become small plants, overwinter, and grow rapidly as days lengthen in February. Winter and early spring vegetables taste sweeter than at other times of the year as vegetables begin to store sugars in their cell walls to protect against frost damage.
November/December/January:
A time of rest and dormancy before the next season really begins again. You can continue to harvest slowly from those plants that are mature, pulling off kale leaves, digging carrots and beets, or cutting spinach. Now is also the time for winter pruning your fruit trees, reading seed catalogues, and planning next year’s garden.
If you do choose to use supplemental lighting, then greenhouse growth does not need to slow down during this time. Leafy greens and root vegetables will thrive in your winter greenhouse with a little added light. We’ve also seen winter greenhouses grow warm-weather crops, like tomatoes and peppers, with supplemental lighting if the greenhouse nighttime temperatures can stay at least above 62 degrees. Because a Ceres greenhouse harvests light through reflecting off of its north, east and west walls, we are able to use less supplemental lighting for strong winter growth.
If you’re new to growing and are wondering what a greenhouse planting schedule would look like for your specific situation, you can enlist the help of one of our grow consultants through our grow support program.

Nowadays the climate is unstable. You don’t know what to expect from the weather tomorrow: snow may suddenly fall in the summer, heat will come in early March, and frosts will strike in April. Therefore, the greenhouse is the surest means for growing vegetable crops and obtaining a high and stable yield.
In the article we will tell you when to plant seedlings in a greenhouse in 2022.

Dependence of terms on the region
Since we are looking at an unheated greenhouse, planting dates may vary depending on where you live.
| Plant movements | |
| The average strip (including the Moscow Region) | Cultures can be planted in a greenhouse on April 20 to mid -May. This is the most optimal and safest time for placing plants in the greenhouse. |
| Northern regions (Siberia, Urals, North-West, Leningrad region) | It is desirable to plant later - about a month, that is, closer to mid-May. In April, there can be no talk of landing: it is still too cold, and a comfortable temperature is an important condition. |
| Southern regions | Here, at the end of March, the air in the greenhouse warms up so much that all crops can be planted. You can work throughout April. |
Terms of planting seedlings in a greenhouse depending on soil temperature
Air and soil temperature is important for all vegetable crops without exception. Usually a polycarbonate greenhouse warms up a little faster, and landing there is carried out a little earlier.
Note
You can safely plant seedlings of vegetable crops when the soil in the greenhouse warms up to +14…+16 degrees. At the same time, ideally, the air temperature in the greenhouse during the day should be at the level of +16 .
.. +17 degrees, and at night it should not fall below +11 degrees.
Lunar calendar for planting seedlings in the greenhouse 2022
Planting usually starts in March and takes place in April, May and June. Consider these four months. For convenience, we have summarized everything in a table.

Cucumbers – about 7–8 days before planting cucumber seedlings in the greenhouse, it is necessary to accustom them to the external environment, that is, take them out to the balcony or greenhouse for a short time.
Advice
Do not take it out for a long time at once. Start with 1.5-2 hours and gradually increase this interval, bringing it up to a day.
Recommendations for planting young cucumbers:
- About a day before planting in the greenhouse, planting holes should be made in the beds. The size of the planting holes should depend on the root ball of your seedlings (the holes should be slightly larger than it). The distance between the holes should be about 30 centimeters.
- An hour before planting a cucumber in a permanent place, it is necessary to water the cucumber seedlings well, soaking the earth ball well.
- Before planting seedlings in the greenhouse , carefully remove the plant from the container, being careful not to disturb the earthen ball in which the sensitive roots of young plants are located. Its damage can lead to inhibition of growth and development of cucumbers in the future. The aerial part also cannot be injured, this can lead to further stunting of plants in growth.
Note
The best option for planting in the ground is by transshipment. Carefully and without damage, remove the earthen ball and plant the plants in a new place.
- It remains to fill the void between the earthen clod and the walls of the hole and pour well with water. You can grow more.

Basically, the technology for moving peppers to the greenhouse is the same as for previous crops.
But there are also subtleties. Young peppers usually do not deepen. Only when, in the process of growing, the rudiments of additional roots form on the stalk. Then this procedure can be carried out so that these roots are fully developed.
Now let's analyze the landing pattern. Usually, 70 cm is left between rows in the greenhouse. It depends on which seedlings are planted in the greenhouse. The distance between the bushes (if we are talking about low-growing varieties) is left about 20 cm. And if you plant varieties characterized by medium growth or tall cultivars, then the distance can be safely increased to 35 cm.
The soil in the garden must be well loosened, leveled, and it must also be well moistened.
Cabbage seedlings are usually planted in rather wide grooves, which are made about 9 centimeters deep.
Be sure to leave a distance of 13–14 centimeters between the grooves.
Tip
Be sure to fill the furrows with nutrient soil taken from purchased seedling soil. It is also recommended to add a small layer of wood ash (about 0.5 cm).
After planting the seedlings, the soil in the furrows should also be watered abundantly.

Young plants of tomatoes can be deepened if necessary, planting to a permanent place.
This has a positive effect on the development of the crop: additional roots are formed on the stem, the plants will grow more actively, consume more nutrients, and the yield will be higher. By that time, the plants should be about 55 days old and have about eight leaves.
High -degree plants are placed, retreating one from the other by 65 cm, and low -speed - 35 cm.

are usually not grown through the seedlings, and direct sowing of seeds in the ground.
It’s great if there is a greenhouse: you can adjust the lighting there, since radishes are a short-day culture.
How to plant radish seedlings in a greenhouse:
- Sowing radishes in a greenhouse is very easy.
- It is necessary to prepare the soil, as for seedlings of cucumbers.
- Make grooves about 10 centimeters apart.
- Water them generously.
- Seeds can then be sown. They should be deepened by 1.5 cm, between the seeds retreat about 3-4 cm of free soil. If you have grown seedlings, then the layout of its placement is exactly the same.

They are also often sown from seeds.
Seeds must be soaked in water for a day before sowing so that they sprout faster. Usually greens are sown in rows.
Recommendation
Do not thicken the crops too much, as they will shade each other and this will reduce the overall green yield. Retreat 10-15 cm between rows, and between plants - 5 centimeters.
Green seeds should be sown in moist and well loosened soil. When planting seedlings, the distance between plants can be increased by 1 cm.
Here's everything you need to know about the correct planting of vegetable seedlings in the greenhouse.

When to plant seedlings in a polycarbonate greenhouse?
Our fertile soil is capable of yielding a rich harvest. The amount of harvested vegetables and herbs, as well as their taste, depends on skill and dexterity. Plants are grown not only in open ground - greenhouses are used for faster maturation. When to sow seeds, at what temperature to plant seedlings and how to prepare a greenhouse? In this article you will find answers to these questions.
What seedlings are planted in the greenhouse?
Beans, onions, cabbage, tomatoes, cucumbers, carrots, herbs, garlic are grown in a greenhouse. Such cultures also feel good in winter if the greenhouse is heated. In the summer, you should not be limited to the usual seedlings. With tomatoes, you can plant bushes of asparagus beans, which in a warm environment will give a greater yield. The nodules on the roots of this plant form nitrogen and nourish the soil well.
Such a neighborhood will benefit the tomatoes. Cucumber seedlings can be planted in a greenhouse together with eggplant and pepper seedlings.
Green onions can be grown in the greenhouse in winter. In severe cold, onions are covered with a layer of humus. In frosty weather, you can also plant dill, which will yield a crop within two months. Seedlings will only need sufficient humidity and temperatures above +15 degrees.
Polycarbonate greenhouses create good conditions for early planting. Due to the honeycomb structure, polycarbonate accumulates heat inside the greenhouse, due to which the temperature in polycarbonate greenhouses is higher than in film or glass ones.
Preparing seedlings for planting in the greenhouse
It is possible to grow strong seedlings with a good root system and strong stems.
The first step is to select a suitable sowing container. Too heavy, large or cramped containers are not suitable for seeds.
In addition, it must have good drainage: holes for draining excess water and stones at the bottom. Otherwise, the seeds may rot. The same seedlings that have risen will not develop normally and will wither away.
Sowing in ordinary plastic cups or pots is the most popular method. They provide protection against root rot, have special drainage holes at the bottom, and seedlings from cups are easy to transplant. But they take up a lot of space, they are difficult to carry, because. You have to carry each glass separately. Wooden or plastic boxes save space significantly, they can be stacked on top of each other. They are easy to carry, and plants are easy to care for. However, removing seedlings from boxes can damage the roots.
Seeds are also sown in paper combs filled with nutrient mixture. When planting seedlings, the material is simply cut and each cell is placed directly into the ground. The plant is not damaged and does not have to take root.
But, unfortunately, it is very difficult to find such paper honeycombs. But they have a worthy replacement - peat cups. Porous walls provide the necessary moisture and air access to the roots.
Seedlings are planted in a greenhouse directly with a glass, which decomposes over time and fertilizes the soil. The pot is environmentally friendly and does not contain pathogenic microbes or toxic substances.
When to sow seedlings in a greenhouse
The sowing time for a particular plant is always indicated on the seed package. To correctly calculate the sowing time, it is worth considering several factors:
- Vegetation period - the time from the appearance of the first sprouts to the full formation of plants. There are early-ripening, mid-ripening and late-ripening varieties. You can find out the features of a particular plant from the inscription on the package with seeds. Tomatoes grow in 80-140 days, eggplants - 100-150, sweet peppers - 90-140, and cabbage 50-190.
Late tomatoes begin to be planted already in mid-February, and early ones - in late March - early April. - The optimal age of seedlings is the time when they most easily endure diving, take root quickly and get sick little. In early tomatoes, this period is 40-50 days, mid-season - 55-60, late - 70, pepper - 50-65, eggplant 45-60.
- Temperature requirements. Eggplant is a very heat-loving vegetable, so it is not worth planting seedlings even in a greenhouse early. This should be done when the likelihood of late frosts has passed. Some varieties of tomatoes and peppers are not so demanding on temperature and can be grown in greenhouse conditions even in cold weather.
- Desired harvest time. To obtain a crop several times a year, the seeds are sown more than once.
- Seed germination period and climatic conditions. There are varieties of plants with cold (determined by temperature and soil moisture) and warm (end of frost) sowing period.
When to plant seedlings in the greenhouse?
When transplanting small seedlings, it is important to make sure that they have strong stems and roots.
Before planting tomato seedlings in a polycarbonate greenhouse, sprouts should be prepared. This process begins 2-3 weeks before transplantation. Watering gradually decreases, and ventilation increases. Seedlings are taken out for a short time to the balcony or a window is opened to lower the temperature in the room by a couple of degrees. Greens are fed with ashes (a glass of 10 liters), and in 7-10 days. stop watering. On the day before planting, the plants are watered abundantly. You can plant seedlings in a greenhouse from May 1 to May 10. At that time, the seedlings had 6-8 leaves and a stem 30-35 cm.
Pepper seedlings are hardened in 10-15 days. The temperature in the room should gradually decrease to 17-18o. At first, the room is ventilated only during the day, and 4 days before, the windows are opened at night.
Seedlings are taken out to a more lit place, and the number of waterings is reduced.
To protect against fungal diseases, a week before planting in the greenhouse, the sprouts are sprayed with a solution of copper sulphate (15g/10l). A few days before planting, the plants are well watered. Seedlings are planted in a greenhouse when the soil has warmed up to a temperature of 18 degrees. This period is May 25-30 or later, depending on the weather. Around the same time, they are transplanting eggplant.
How to prepare a greenhouse?
All experienced summer residents and farmers know that preparatory work in the greenhouse begins in the autumn. It is then that it is disinfected, all waste, unnecessary twine, ropes, twine are removed from it. Doors and windows close securely to prevent wind or precipitation from damaging the greenhouse. If these rules are followed in the spring, there will be less work in the greenhouse - no repairs, pest control, or cleaning will be needed.
Preparatory work in the spring will be as follows:
- Polyethylene greenhouses are checked for holes, glass greenhouses for cracks, and polycarbonate greenhouses for frame deflection from snow loads and cracks in polycarbonate.
- Thorough cleaning, removal of last year's tops, mosses, lichens. Next, the greenhouse is washed inside and out. Polycarbonate is cleaned only with soft sponges or brushes with a non-abrasive agent.
- Decontamination (chemicals, natural remedies, biologics). Replacing the topsoil with humus with mineral fertilizers.
- Fertilization.
To fertilize the soil, it is important to look up to the plants that will be grown. Some mix loam, manure and peat in a ratio of 4:3:3. Someone just mixes loamy soil with humus 6:4. On top, you can lay out a layer of rotted sawdust, hay or straw and sprinkle with peat.
To adapt the soil to a particular seedling, measure its Ph. In accordance with the indicators, the acidity of the soil is regulated by lowland or highland peat.
