Wondering when to prune gardenias to keep these plants the right size for your backyard, and shapely, too? While very little pruning of these prized shrubs is necessary, it is definitely a task worth adding to a gardening to-do list for a handsome feature plant, and it’s important to get the timing right.

On the desirable evergreen shrubs list for many gardeners in the south – as well as that of those located in colder zones who are prepared to move their plants indoors in winter – gardenias are adored for their showy, fragrant blooms and attractive foliage.

But to help them look their best, pruning is a good idea, and this is the lowdown on when to prune gardenias.

When to prune gardenias

Gardenias are one of the best flowering shrubs for busy gardeners because they don’t have to be pruned much. But pruning will keep them in shape, and will allow the removal of broken stems.  

If you’ve chosen gardenias to plant with hydrangeas, or have a smaller yard, and therefore want to keep them more compact, prune gardenias every year. But if letting them grow bigger works within the garden design, pruning every two or even every three years can be sufficient to keep them to the dimensions and shape you want.

What time of year to prune gardenias

While when to prune gardenias can vary from annually to two or even three yearly, the rules are stricter when it comes to the time of year to prune them. Get it wrong and fewer flowers can be the result.

‘For trees and shrubs that are grown for their flowers, you must consider when they bloom before you decide to prune them,’ say Daniel Gill and Thomas A Merrill at LSU Ag Center . 

Be aware that gardenias may bloom just once a year, or more than once, so you should be sure about the variety in order to know when to prune. 

Prune gardenias after flowering

Gardenias should be pruned right after the last flower has bloomed. ‘Gardenias, like azaleas, would need to be pruned after they have finished flowering, which will be sometime late spring or early summer,’ say the experts at UF/IFAS Extension Nassau County .

Pruning a gardenia at this time of year avoids the risk of cutting away new buds, which could happen if you prune in the fall.

The timing is driven by the fact that new buds develop on older wood. Gardenias ‘bloom in early summer, but they produced their flower buds from last year’s growth’, explain Daniel Gill and Thomas A Merrill.

For gardenias that bloom more than once, wait until the end of the final blooming cycle to prune.

Can I prune gardenias in winter?

You shouldn’t prune gardenias in winter because you risk reducing the number of flowers that will bloom next time around. Prune in summer instead when older wood can be cut back without risking the removal of newly formed flower buds.

In summer wait until the last of the shrub’s flowers has fallen and then prune for best results.

Should you deadhead gardenias?

It is a good idea to deadhead gardenias. Removing spent blooms prevents the plant from setting seed. Deadhead a gardenia after the blooms wilt and it will direct its energy into producing flowers allowing you to enjoy more of the wonderful blooms. Remove old flowers and the shrub will look more attractive, too. 

It’s worth deadheading a gardenia weekly throughout the blooming season, pinching off spent flowers or cutting them off just above a leaf set. When the last of the year’s blooms have faded, you can prune gardenias if you want to improve their shape or remove broken stems.

How to Prune a Gardenia Bush in 5 Simple Steps

A gardenia bush should be pruned with proper techniques and at the right time to prevent any kind of damage to the plant health. Read this article to know how to prune a gardenia bush.

Gardenia bush is well-known for its shiny, dark green foliage and beautiful white flowers with exquisite fragrance. Growing gardenia is a pretty simple task. It can be grown outdoors as well as indoors. It grows well in a warm climate. Therefore, in those areas where the winter is intolerable, this ornamental shrub is grown indoors in containers as a houseplant. It should be planted in a rich, well-drained soil and placed in one such location where it receives the morning sun. Pruning gardenia is a part of the plant care. However, it does not require pruning to keep the plant healthy. Rather, it is pruned for aesthetic reasons.

Two of the most important aspects of gardenia care are the timing of the pruning and the tools to be used for the job. The main steps on how to prune a gardenia bush are as follows:

Step #1

Selection of the right pruning time for gardenia bush is very important. It should be done only after its blooming season is over, but before the new buds of the next season make their appearances. Pruning is avoided during blooming period as it causes significant damage to the existing blossoms. On the other hand, it should be pruned prior to the onset of fall when the new buds appear. Pruning in fall season can badly ruin blossoms of the new season. Therefore, the ideal time for pruning the bush is late summer or early fall.

Step #2

You can prune gardenia bushes with small hand pruners. Always use sharp pruning shears for this job to ensure an even cut. Uneven cuts can make the plant prone to diseases. Bypass pruners are mostly recommended for pruning gardenia bush as it works like a pair of scissors. Thus, it gives clean cuts that can heal fast, which reduces the chances of any future problems in the plant after pruning.

Step #3

First of all, you have to eliminate all the damaged and diseased parts of the plant. Pinch out all the dead or wilted blooms from the plant. If any of the branches show signs of disease or fungal infestation, then cut them out from the base. While pruning, keep the pruner at a 45 degree angle. After pruning the diseased parts of the plant, you must wipe off the shears with a disinfected rag or else the disease may spread to other branches that come in contact with it. You may come across some stems that do not have any growth. Those are probably dead stems and you must cut them out.

Step #4

Make a thorough inspection of the shrub from all sides and angles to identify the locations of the stems and leaves that are protruding out. Pruning is done to eliminate these extra shoots that keep growing from all directions in order to give a more fuller look to the shrub. You should trim the branches that are growing laterally as they can ruin the shape of the bush later on. You can also give a desired shape and size to the foliage. For this, you have to prune several inches along the edges of the plant. Maximum pruning should be done at the topmost part of the plant. This will improve air circulation through the foliage and promote growth of new shoots.

Step #5

While pruning gardenia, you must keep one thing in mind that you cannot prune more than one-third of the plant. Once you finish pruning, all trash materials should be disposed off immediately. Otherwise, the pests from the diseased branches may attack the bush all over again. Do not water the plant for the next few hours after pruning.

Usually, a gardenia bush does not have vigorous growth. So, you can prune it after a gap of two years, although most people prefer to prune it once a year to maintain an attractive shape.

Gardenia is a flower from a genus of tropical plants, the Rubiaceae family. The name was given in honor of the American naturalist A. Garden. It grows in Asia, Africa, Japan and China, prefers tropical and subtropical climates. Gardenia flowers are painted in delicate shades of creamy white, they are distinguished by incredible grace and intoxicating aroma.

Peculiarities of growing gardenia

Gardenia is characterized by great capriciousness and demanding care. In order for the plant to grow well and give abundant flowering, a lot of effort will have to be made.

Planting a Gardenia

Before planting, you should first choose a specific variety that is most suitable for climatic conditions.

Important: When choosing a planting site, make sure that the soil is sufficiently acidic, according to the preferences of the plant.

Planting methods

Gardenia can be planted in open ground or in a decorative pot.

When planting in the ground, water the ground first. Then they dig a hole of sufficient depth into which the entire root system could easily fit. Next, the roots are placed in a prepared place, sprinkled with earth, which is lightly tamped. Cover the soil with mulch.

The first watering of the planted plant should take place a day later if there was no natural precipitation the day before. Fertilizers that need acidic fertilizers should be applied up to several times a year.

In order to plant a gardenia in a pot, you must first fill the selected container with earth, pour warm water and mix thoroughly. The soil should become moist, without air cavities.

The stem is placed in the center, fertilizer is added, the pot is placed in a place open to sunlight. Watering should be done once a week on a regular schedule.

Optimum planting time

The most preferred planting time is the winter-spring period.

How to choose the right soil (Soil composition)

When growing gardenia, it is necessary to stock up on acidic soil, which is quite loose and highly fertile. Suitable slightly acidic substrate, the same as azaleas. It can be prepared independently from the same parts of coniferous, soddy land, as well as peat and sand. In this case, sand can be replaced with perlite or vermiculite in a ratio of 3: 1.

The substrate tends to leach over time. Restoration of acidity will help watering the flower two or three times a month with a slightly acidic solution, for example, water in a volume of 1 liter, where a couple of drops of citric acid were diluted and ferrous sulfate (0. 5 g / l) was added. You can also use water infused with peat.

Features of gardenia care at home

Caring for a flower requires strict adherence to a number of rules that will help ensure a favorable environment.

Location and lighting

Gardenia belongs to light-loving plants and requires a lot of lighting.

The light needs to be bright and diffused. Direct sunlight in a hot summer will not do her any good, while the brightest place in winter does not pose a danger to direct exposure.

It is best to place the flower on windows facing west or east. The pot, exposed to the south window, needs to be slightly protected with a cloth during the hours of maximum sun activity. A flower growing in a north window will need additional light, which can be created using fluorescent lights. Lack of light leads to wilting of the stem and dropping of the buds.

The flower is extremely sensitive to temperature changes, it should not be placed under an open window or on a balcony.

Humidity

Gardenia, like all tropical plants, needs a high level of humidity, especially during budding. This can be achieved by placing moistened peat or sphagnum in the pan where the pot stands, while avoiding immersing the bottom in water.

Foliar spraying, especially in summer, should be done several times a day. In winter, it should be reduced and done no more than once every two days. When spraying, it is best to use a spray bottle, avoiding droplets on flowers and leaves, leading to brown spots. For the same reason, the most suitable time for spraying a flower is the first half of the day, which will allow the moisture lingering on the leaves to evaporate before nightfall. During the flowering period, spraying is best replaced by wiping with a soft cloth moistened with water.

Temperature regime

Compliance with the temperature regime is one of the most important factors for good survival of gardenias. The optimal temperature for its successful growth in spring and summer is 22-24°C. In autumn, the temperature should be slightly reduced to 18°C, as well as in winter. At this time of the year, it is necessary to ensure that the flower warms up the air at night to 16 ° C. A slight decrease favorably affects the laying of the kidneys. Overheating in winter (over 22°C) will encourage overgrowth preventing bud formation.

The danger is a strong cooling of the root system. Drafts can be detrimental to a flower.

Watering schedule

When it comes to watering, the plant is unusually capricious. He needs water

strictly at room temperature. If it is chilled, it will cause the leaves to turn yellow and grow poorly. Generally, gardenias respond well to rainwater.

More water will be required during growth. Immediately after the top layer has dried, the next one should be applied, but water should not stagnate in the pan. With the onset of autumn, reduce watering to moderate, each time waiting 2-3 days. Even less water is required with the onset of winter. The dormancy time of the flower is 4 to 6 weeks. As a rule, it falls on the end of March - the beginning of April, one month before flowering. Moderate watering at this time will help proper budding. However, the soil must not be allowed to dry out. Also, do not forget about observing the level of acidity necessary for the absorption of mineral supplements, and add a solution of citric acid in time.

Tip: You can check the acidity with litmus paper, for this purpose, a pinch of earth is poured with water, which is then drained and the soil is tested.

Top dressing and fertilizers for gardenia

Additional nutrition, which gardenia needs especially in spring and summer, will help create favorable conditions for the plant. At this time, top dressing will be required twice a month. Fertilizers for flowering plants are suitable, with alternating organic and mineral, without calcium. It is necessary to feed adult plants before the onset of autumn, and do this regularly.

For feeding gardenias, liquid concentrates, such as Vito, as well as peat-humic fertilizers, are suitable.

The first dressing of a flower bought in a store will be needed in six months. If signs of chlorosis are found, ferovit and iron chelate should be added to the top dressing.

Pruning

To form an ornamental gardenia shrub, you need to trim it. A suitable time is the period after the end of flowering or immediately before planting. To do this, the shoots are shortened by about half. Avoiding damage to the flower during active growth, you should pinch new shoots at the very top of the bush.

Pruning the bush will stimulate the growth of additional lateral shoots and will ensure lush flowering, even formation of the bush in the next season.

Tip: Shoots that have been cut at the time of pinching are suitable for flower propagation.

Pruning methods

The main technique for achieving a spherical crown is to cut off all side shoots in early spring. The leaves do not need to be touched. On an elongated seedling, you need to pinch the bud located at the very top, then you can create a neat tree. To do this, only 3-4 buds are left at the top, all the rest are cut off along with the foliage. After waiting for a noticeable growth of the left branches, pinch the buds on them too.

Significantly ease the effect of pruning on a flower by watering it with a large amount of water a day before the planned pruning. Then do the processing of the cuts using charcoal.

Transplanting

Gardenias are usually sold as a whole plant, so they need to be transplanted to develop properly.

In order to avoid damage to the root system of the flower, which can often be very tangled roots, it is best to use the transfer method for transplantation, transporting together with an earthen clod. The procedure should be carried out regularly, every year, after the end of flowering.

Transplanting methods

For mature plants, repotting once every three to four years will suffice.

Azalea soil is suitable as gardenia transplant soil. It can be purchased at flower shops or nurseries, or you can make your own.

Before transplanting, plants should be placed in water heated at room temperature for one hour to separate excess soil and untangle the roots.

Next, it is recommended to lower the flower into a solution in which the growth stimulator "Kornevin" is diluted for two hours. During transshipment, the soil on the roots is left, new soil is poured into the pot. The lower part of the stem should enter the ground only 0.5-1 cm in order to avoid death from sudden decay.

Propagation of gardenia

If desired, you can propagate gardenia, but this process will be quite complicated and cause a lot of trouble.

Methods of reproduction (Basic methods, subtleties)

There are several ways of reproduction of a flower. The most common is cuttings using stems. To do this, you need to take shoots from the top up to 10 cm high. Then prepare warm soil by adding a root formation stimulator to it. A positive result will be facilitated by the placement of cuttings in a mini greenhouse. They need to be covered with glass or film. The room must be ventilated daily. A temperature regime of at least 25°C must be observed. Bottom heating has a beneficial effect.

When does gardenia bloom?

Gardenia blooms from May to August.

Flowering time flower shape

Flowering time can be up to six months, depending on the size of the plant and the number of buds that have appeared, which usually open in turn. In rare cases, repeated flowering is possible closer to winter.

What to do after flowering

Withered flowers must be removed, freeing the plant's strength for the formation of young shoots.

The most famous species and varieties of plants

In the home environment, jasmine gardenia or, more correctly, jasmine-like, has taken root best of all. It is distinguished by high decorative qualities. She is extremely warm-hearted. In hot countries it is grown in gardens, in areas with a cool climate - in rooms or greenhouses.

Currently, a large number of different varieties of this species are known:

Problems, diseases and pests of the flower

When breeding gardenia indoors, various problems may arise, including massive dropping of buds. This can be caused by dry air, an earthy coma, a sharp drop in air temperature. Too low temperatures and the lack of the necessary acidity of the substrate leads to discoloration of the leaves, called chlorosis.

Gardenias are susceptible to pests such as:

To combat them, spraying with an insecticide solution will help twice, spacing up to 5 days between treatments. The infected plant should be isolated.

Useful tips (Note to the florist)

A favorable gardenia care regimen that allows you to maintain its lush flowering, prevent buds and leaves from falling off, includes a number of basic rules:

Answers to readers' questions

Difficulties in caring for gardenia often stop many growers from buying it, however, many questions that arise in practice have already been answered.

Lifespan

If the plant is cared for correctly, its life cycle can last up to seven years.

Is gardenia poisonous?

Gardenia refers to plants, all parts of which are poisonous. Its fruits, which can cause indigestion, are especially dangerous for health. To prevent undesirable consequences, it is necessary to wash your hands thoroughly after touching the color.

Why doesn't the flower bloom?

As a rule, the lack of flowering of gardenia can be observed in two cases:

Favorable temperature conditions, sufficient illumination, air humidity, and the supply of nutrients to the soil within the normal range are of great importance.

Tip: If the plant does not form buds, more frequent spraying will help, placing the pot on wet expanded clay, lowering the air temperature to 18 ° C.

Why do leaves turn yellow (blacken, dry)?

Incorrect watering of gardenias can cause the leaves to suddenly turn yellow. The reason may be both excessive moisture and drying of the soil. All these factors lead to the development of root diseases, which affect the quality of the foliage. In addition to yellowness, they can cause blackening of the leaves.

Iron deficiency may be another reason. This happens when too hard water is used. Fertilizing the plant with iron chelate (Ferovit) will come to the rescue. They are applied strictly according to the instructions until the flower is completely healed.

Gardenia why do the buds fall off?

If there are too strong changes in air temperature in the room where gardenia grows, as well as with errors in the irrigation regime, buds may fall off. In addition, fall can be caused by reasons such as:

Important: At the moment of budding, the flower shows a particularly sharp reaction to any changes in environmental conditions.
