Spinach Planting & Spinach Growing

Spinach is a fast-growing plant, yielding many leaves in a short time in the mild weather of spring and fall. Get expert tips for growing spinach.

Spinach is a cool-weather vegetable related to beets and Swiss chard. A fast-growing plant, it yields many leaves in a short time in the mild weather of spring and fall. When growing spinach, the trick lies in making it last as long as possible, especially in the spring, when lengthening days shorten its life. One great way to do that is to start with vigorous young Bonnie Plants® spinach plants, which are already well on their way to maturity when you put them in your garden. Although it prefers full sun, spinach will still produce a respectable harvest in partial shade.

Quick Guide to Growing Spinach

Soil, Planting, and Care

Spinach grows most quickly in well-drained soil rich in organic matter such as compost or composted manure and with a pH of 6.5 to 7. A simple way to improve your existing soil is to mix 3 inches of aged compost-enriched Miracle-Gro® Performance Organics® All Purpose In-Ground Soil with the top 6 inches of existing soil. In order to grow spinach twice a year, plant it about 4 to 6 weeks before the last frost in the spring, and again 6 to 8 weeks before the first frost in the fall. Space plants 12 inches apart; this gives leaves room to reach full size. Perhaps the easiest growing option is to plant spinach in pots filled with premium quality potting mix, such as Miracle-Gro® Performance Organics® All Purpose Container Mix which will provide roots with just the right environment for strong growth.

For the most tender leaves, encourage spinach to grow fast and without interruption by fertilizing regularly with a water-soluble fertilizer like Miracle-Gro® Performance Organics® Edibles Plant Nutrition that feeds the soil along with the plants for better growth. (Be sure to follow directions.) This plant food works in tandem with great soil to help you achieve the best possible spinach harvest.

In the spring, plants will grow tall and bloom (called bolting) as soon as the days are longer than 14 hours. Heat also speeds up bolting, since spinach prefers temperatures between 35 and 75 degrees. Our variety is slow to bolt, which is a real bonus for gardeners who don't have the luxury of long stretches of mild weather.

Because it bolts in the lengthening days of spring, spinach is an especially popular crop for fall, when days are short and cool. Plants are very cold-hardy, tolerating temperatures as cold as the teens to low 20s once they are well established. This quality makes them great for overwintering over in zones 8 and southward.

In cold climates, some gardeners plant spinach in a cold frame or cover plants with hay and leave them all winter; they'll be first to produce a very early spring harvest.

Troubleshooting

Heat and long days will end your crop, so plant as mentioned above. Pests that enjoy spinach include flea beetles, spider mites, and aphids, which feed on the leaves. Diseases that attack plants are downy mildew (a mildew that may appear during cool, moist weather) and white rust (which causes white spots on the leaves). For instructions on how to fight back against these pests and diseases, contact your local Extension agency.

Harvest and Storage

Spinach leaves are ready to harvest as soon as they are big enough to eat. Harvest by removing only the outer leaves and allowing the center leaves to grow larger; this will allow the plant to keep producing. Picking the outer leaves also gives the advantage of briefly delaying bolting. In spring, when plants are about to bolt, pull the entire plant at once to enjoy the leaves before they become bitter.

A bowl planter filled with spinach plants makes a great small cool-season garden. Spinach is one of the most cold tolerant vegetable plants.When spinach begins to bolt in warm weather, it tastes bitter and is ready to be pulled. The plants look tall and spindly with thick stalks when they start flowering.These spinach plants grow close together so that they can be thinned as they are harvested.

FAQs

When is the best time to plant spinach?

In late winter or early spring for a fast crop and again in late summer or early fall, after the hottest temperatures have passed. Spinach is a cool-weather vegetable.

How can I know when my spinach is ready for harvest? What is the method of harvesting?

When the outer leaves are about 6 inches long, they're ready to be harvested. Or, if it is spring and plants are near the end of the season where they will soon bolt (bloom), you can pull up or cut the entire plant.

My spinach bolted, and I cut the plants just above the soil line.

Will I get another crop from them?

No, they are finished. It is time to pull them up and replace them with a warm-weather crop. You can plant spinach again in late summer for a fall harvest.

Spinach is an undemanding plant that’s a joy to grow and even more of a joy to eat.

 

When, Where and How to Plant Spinach

Spinach can be either sown directly into the garden or started from seeds indoors. For the least work and the most convenience, seedlings can also be purchased from a nursery in spring.

To give spinach a head start, plant seeds in sterile seed-starting mix indoors about six weeks before the last expected frost date. The seeds will germinate one to two weeks later in soil that is between 60 and 68 degrees. If growing in a room that stays cool, consider using a seed-starting mat that will raise the temperature of the soil.

Spinach is frost tolerant, so it can go in the ground long before many other crops. When spinach seedlings have two true leaves and when there are four or fewer weeks remaining until your last frost date, the seedlings may be transplanted outdoors.  

Seeds can be planted outdoors as soon as the soil is workable in spring — about six weeks before the last expected frost — and they will germinate as the days warm.

To germinate seeds faster and more reliably, there is a process called “priming.” A week before sowing spinach seeds indoors or out, soak seeds in room temperature water overnight or up to 24 hours. Next, place the seeds on a paper towel to air dry for one or two days. Once the seeds appear dry, place them in an airtight container and store the container in a cool place. The seeds will have soaked up and retained enough water to stimulate the first stages of germination. Wait at least five days, but no more than seven, and sow the seeds. 

Primed spinach seeds will germinate both faster and more uniformly: In about five days, the grass-like seedlings will emerge. 

Spinach seeds last up to three years in storage. If in doubt about the age or viability of spinach seeds, prime and sow a few seeds early to test the batch. If the test seeds don’t germinate, it’s time for a new packet.

For a steady harvest over several weeks, a good strategy is to plant a new crop every 10 days. Each crop can be sown directly, or you can stagger plantings of both seeds and seedlings. Continue these succession plantings until it’s time for summer crops to go in. When late summer comes, start up again for fall crops.

Spinach grows well in a wide variety of soils, but like most crops, it does best when the soil is well amended with lots of organic matter, especially compost. The ideal pH range for spinach, like many common vegetable crops, is 6.5 to 7.0. A soil test can tell you if you are near the target and, if not, what amendments can be added to the soil.

Spinach will grow best in full sun — six to eight hours of direct sunlight — or partial shade.

Follow the spacing instructions that come on the seed packets for the variety you have, or plant just a little denser with a plan to later eat the baby spinach that you will remove while thinning the crop.

 

Spinach can be planted outdoors before most crops can because it is frost-tolerant.

 

Types & Varieties of Spinach

 

There are two main types of spinach: Savoy and smooth-leafed.

Savoy spinach and semi-savoyed spinach have dark green leaves characterized by their wavy or puckered leaves, and they include some of the best varieties for growing in cold weather. And yet, some savoy spinach varieties are adapted to withstand heat, offering the best of both worlds.

Smooth-leafed spinach, also called flat-leaf spinach, is the kind you often see in salads. It can be harvested as baby greens for sweeter, more tender leaves, or allowed to grow. 

Auroch is a fast-growing smooth-leafed spinach that performs best in fall, winter and early spring, with a high resistance to downy mildew. It’s ready for harvest in 24 days.

Bloomsdale is a classic variety of savoy spinach that withstands heat better than others, so it offers the best of both worlds, and it’s renowned for its garden-fresh flavor. In 50 days, it produces thick, succulent, dark-green leaves that are very sweet in salads. When planted in autumn, Bloomsdale will overwinter and mature in the early spring, though it’s best sown in early spring for late spring and early summer harvests.

Gazelle is a smooth-leafed spinach with uniform leaves and bunches that make it perfect for baby leaf harvest.  It’s also highly downy mildew resistant and ready for harvest in just 26 days.

Palco matures in 38 days and is adaptable as both a cool-season or warm-season crop. It is a flat-leaf spinach that may be harvested as baby greens or enjoyed after attaining its full size. It is both bolt and mildew resistant. 

Red Tabby is a red-veined smooth-leafed spinach with angular leaves in an upright growing habit. It matures in a month and is downy mildew resistant. 

Renegade has fleshy, round, smooth, dark green leaves and sweet, tender stems. It’s a flat-leaf spinach that matures in 42 days.

Space is a slightly savoyed spinach with medium green leaves that are highly resistant to downy mildew and mature in just 25 days. It is versatile — grow it in all seasons.

 

Spinach comes in a wide variety of shapes, textures growing habits and even colors.

 

Watering Spinach

Spinach is a thirsty crop that enjoys up to 1.5 inches of water a week. If it hasn’t rained that much in a week, make up the difference with supplemental irrigation. Water under the foliage, right at ground level, to avoid wetting the leaves, which invites plant diseases. When growing spinach, it’s really nice to have a drip irrigation system for a slow and consistent application of water — but it’s not necessary as long as you keep on top of watering the garden when Mother Nature fails to.

A 2-inch layer of organic mulch such as shredded leaves, pine bark or straw will help keep the soil cool and moist between waterings.

 

Organic mulch around spinach plants will keep the soil moist between waterings.

 

Fertilizing Spinach

As long as you have good rich soil, spinach isn’t a demanding plant. But it can help to add some organic nitrogen-based fertilizer — like alfalfa, soybean meal or blood meal — at planting time. Adding compost before planting will also help the plants along, and balancing the pH will ensure the nutrients in the soil are readily available to the plants.

Spinach Pests & Diseases

When it comes to pests and diseases, spinach is a gardener’s dream since it rarely succumbs to any serious problems. 

Provide adequate spacing to allow for good air circulation to avoid mildew. If downy mildew does become a problem, practice crop rotation or choose resistant varieties.

Proactively check for slugs, which are easily controlled with a number of environmentally-friendly options, including handpicking, placing bowls of beer near the plants at soil level, or using a pet-safe iron phosphate bait like Sluggo. 

 

Spacing spinach adequately at planting time can reduce instances of mildew later.

 

Harvesting Spinach

And of course, the best part of spinach is eating it. You can harvest spinach whenever you want. This is one of those cut-and-come-again plants that I love so much since new leaves will resprout to replace the ones you cut. Simply snip away individual leaves as soon as they’re big enough to use.  Or you can cut the entire plant about an inch above the soil level. Cutting encourages new growth and another crop of leaves and that makes me a very happy and healthy gardener!

When spinach bolts — that means it has sent up a flower stalk and “gone to seed” — it becomes bitter. This happens when the weather heats up in summer. At this point, the plant is done. Pull it out and add it to the compost pile, and plant your next crop in its place.

terms of sowing and rules for growing in the garden

Spinach is a vegetable crop that contains in its leaves a lot of useful vitamins that are indispensable for the functioning of the human body. Therefore, gardeners who decide to switch to a healthy diet sooner or later ask themselves how to plant a plant. In order for the planting of spinach to be successful, and the bed soon covered with juicy rosettes, you need to know everything about the specifics of growing vegetables in the garden.

Well, here's how and when to plant spinach outdoors in spring and autumn. nine0003

    Since spinach is a cold-resistant plant, spring planting in open ground is carried out immediately after the ground thaws .

    As regards temperature , the spinach sowing starts when it gets warmer outside to +5 degrees and further increase is predicted.

    In the Middle lane (Moscow region) this time falls on the second half of April .

    And in autumn, spinach is planted before winter , similarly to winter garlic or onions , i.e. from end of September to November (depending on the region). nine0003

    Lunar calendar 2022

    Many gardeners often refer to Lunar calendar for specific dates for greater discipline.

    According to the lunar calendar in 2022 favorable days for planting spinach in open ground are:

  • in April - 3-9, 12-15, 26-27;
  • in May - 1-6, 10-15, 19, 24, 31.
  • Unfavorable days according to the lunar calendar for 2022 for sowing spinach are the following dates (Full Moon days and New Moon , as well as the period when the Moon is in Aquarius, because it is a barren and dry sign - is italicized ) :

    How to plant spinach outdoors: preparation and planting

    The desire to get spinach in the garden can simply disappear after a few unsuccessful plantings. To prevent this from happening, you need to know all the requirements for growing this vegetable crop.

    How to choose a planting site

    It is better to plant spinach in well-lit areas where water does not stagnate. To harvest as early as possible, the plant is placed on the southern slopes, which are protected from cold winds. nine0003

    If there is nowhere to plant bushes except for a lowland, the crop is sown on ridges, which are fenced with hard rock boards. Due to the fact that the root system of the plant is short, the mound may be small.

    Since spinach is compatible with most horticultural crops, there is practically no need to consider predecessors and neighbors when choosing. The only thing worth paying attention to is how the previous crop was fertilized - the more top dressing was made last year, the better for spinach. These rules apply to all cultivated plants, except beets, since plants are subject to the same diseases and pests. nine0003

    What kind of soil is needed and how to prepare it

    Spinach likes to grow on nutritious and loose soils (sandy or loamy), neutral acidity (pH 6-7).

    If the soil in the area is excessively acidic, dolomite flour is added to the soil in advance (in autumn).

    In autumn phosphorus - potash fertilizers are applied to the soil ( superphosphate and potassium sulfate or wood ash and bone meal ), as well as organic matter (compost, humus). And in the spring they add nitrogen ( urea or ammonium nitrate ).

    To improve the structure of heavy clay soils, additional peat and sand can be added.

    How to prepare the seeds

    Soak the seedlings in warm water to speed up germination. If the seeds of many crops need several hours of soaking, then spinach seeds are kept in water for 24-48 hours. This feature is due to the fact that the planting material is covered with a hard shell through which moisture is difficult to absorb. Place the container for germination in a warm place and periodically change the water. At the end of the period, the spinach seeds taken out of the water are slightly dried and sown in open ground. nine0003

    Direct planting

    The first thing to do before planting spinach seeds outdoors is to loosen the soil with a rake and then level it. If the landing will be made on the ridges, an embankment is created at the chosen place and fenced with improvised materials. On a prepared bed, rows are made with a wooden plank 2 cm deep. The optimal distance between rows is 15-20 cm, and between plants - 7-10 cm. Seed consumption for sowing 1 sq.m. area - 4-5 g.

    If the bushes are planted too densely, the plants will develop more slowly. In order to be sure that enough plants will grow in the garden and the place will not be empty, you can reduce the step between the bushes in the rows. However, if the seed germination is 100%, the plantings will have to be thinned out. The soil in the recess is watered with warm water, the seeds are laid out. Then the crops are carefully covered with a rake, while slightly crushing the soil.

    To reduce the evaporation of moisture and slow down the growth of weeds, the bed is mulched with hay, dry leaves, chopped straw. If the landing is done correctly, and the weather turned out to be favorable, the first shoots will appear after 2 weeks. nine0003

    How to care for spinach after planting

    In order for plants to give a good harvest, they need to provide comfortable conditions for growth. What is the care of spinach after planting?

    Watering

    The soil on which the greenery grows must be constantly moist, but in no case swampy. Due to the constant overflow, the plants do not grow well and after a while they are affected by root rot. nine0003

    It is especially important to water the spinach during hot weather, as stemming begins due to insufficient moisture. Water the bushes 2-3 times a week. Water consumption per 1 sq. m beds - 3 l.

    Top dressing

    During the growing season, it is not recommended to feed greens with fertilizers that contain a large amount of phosphorus and potassium.

    Leaves of plants that are deficient in chemical elements gradually turn into a different color or die. nine0003

    The fertilizers selected for feeding spinach must be applied strictly at the dose recommended by the manufacturer, otherwise excess nutrients will provoke premature bolting.

    Important! It is impossible to feed greens during growth with fresh organic matter, as it distorts the taste of the leaves.

    Weeding and loosening

    To grow even the most unpretentious crop, you need to pull out weeds as needed. As you know, these plants suck out a lot of nutrients from the soil and compact the soil, which adversely affects the state of the crop, and, accordingly, the yield. In the case when the distance between shoots is much less than 7-10 cm, the extra bushes are removed. To reduce stress on surrounding bushes, water the bed sparingly after thinning. nine0003

    The first time the soil is loosened when the seedlings are 2-3 days old. To do this, gently destroy the formed crust with a rake, thereby improving soil aeration. In the future, loosening is carried out after each watering or rain.

    Shelter in the heat

    Since spinach does not tolerate summer heat, in July, when the air temperature often exceeds +26 C, plantings need to be shaded. To cool the soil and bushes from overheating, a small tent is installed over the spinach plantation or the bed is covered with a special shading net. nine0003

    Important! It is impossible to grow succulent leaves without abundant watering and building a shelter. Under the influence of high temperature and lack of water, the leaves become hard and tasteless.

    Pests and diseases of spinach

    The tender leaves are enjoyed by aphids, leafminers and naked slugs. Do not mind eating greens and snails. Spinach growing in a thickened state suffers from downy mildew. Bushes become infected with spotting and root rot. nine0003

    Since it is impossible to treat greens with chemicals, it is better to try to prevent the appearance of pathogenic microorganisms. To protect plantings from damage, you need to properly care for them: water, loosen, weed. In order to prevent powdery mildew, bushes are planted at a sufficient distance. Also, for planting, it is recommended to choose spinach varieties with high immunity to all kinds of diseases.

    When to harvest and how to store

    In order for spinach leaves to be tender and tasty, they need to be harvested in time. If you delay the recommended time, the leaves will become stiff and lose their taste. Spinach harvest begins 8-10 weeks after germination.

    You can determine whether spinach is ready for harvesting by the type of bush - you can harvest greens immediately after the formation of 5-6 leaves on the plant.

    Spinach is harvested by cutting individual leaves or a whole rosette. The plant is also uprooted. Before putting the uprooted plants into containers, the rhizome is washed, trying not to splatter the leaves. Then the washed part is blotted with a paper towel and placed root down in the box. nine0003

    Important! Spinach should not be harvested immediately after watering or rain: wet leaves rot shortly after cutting.

    Store the spinach in the top section of the refrigerator. Since fresh leaves are stored on average for 1-2 weeks, they are dried, frozen or canned for the winter.

    Thus, if you carefully understand the agrotechnical requirements, planting spinach will not cause difficulties even for an amateur gardener. All that an unpretentious culture needs for normal growth is a sufficient amount of moisture and fertile soil. nine0003
