Gardenia is an indoor flower known among gardeners for its vagaries when grown. But if you properly care for her at home, she will certainly respond to the work and time spent.
Botanical description and plant varieties
Gardenia (Gardenia) is a plant that belongs to the Marenova family. The ancestors of these indoor flowers come from the moist forests of Asia. Botany today knows about 250 species of gardenia, which in the wild are evergreen bushes, but some of them can reach the size of a tree.
At home, they grow mainly jasmine gardenia, which has a pleasant subtle odor. The height of a houseplant in a pot usually does not exceed 50 cm, although it can reach 1-2 meters. It has attractive leaves in a deep green hue.
The flowering period of this plant begins in mid-summer - July, and continues until the height of autumn. The flowers are in the shape of small roses.

Indoor Gardenia: Home Care for Beginners
When growing this flower, you will have to be patient, because it is very demanding on the conditions. For its proper development, it is necessary to provide a sufficient amount of moisture and light rays, as well as protect from drafts. Mistakes in care lead to dropping buds and drying out of the leaves, and in the long run - the complete death of the plant. But if you "make friends" with the plant, then it is sure to please its delicate flowers in abundance.
It is best to put a flower pot on the east or west window. If you put it on the south side, then at lunchtime the plant will need to create artificial shading. With insufficient lighting (for example, in winter or when growing on the north window), additional illumination will be needed using lamps that are placed at a distance of 60 cm from the gardenia.
It is important to remember that even turning plants over can cause flowers and buds to fall, so this is not recommended.
The optimum resting temperature is 18 ° C. In spring and summer, it should reach 24 ° C. Hypothermia and drafts have a very negative effect on the plant. This flower is very fond of high humidity, so next to the pot you need to place containers with water or put it in a tray with moistened peat or sphagnum.
How to grow gardenia
Features of watering
Gardenia likes moisture, but overfilling can lead to fatal rotting of the roots. Therefore, the plant should be watered when the top layer of the earth is already completely dry. The frequency of this procedure also depends on the period in which the flower is:
- from mid-October, watering is carried out once every 2-3 days;
- in the winter months, once every 4 days is enough.
Since this shrub loves acidic soil, it will be useful to add a couple drops of lemon juice when watering.
Gardenia also loves spraying from a spray bottle and a warm shower, because its historic homeland is tropical forests. Dry air is one of the main enemies of health and the decorative appearance of plants.. Especially moistening the green part is necessary in the hot sultry months. You can put the pot in the bathroom and water from the shower, after covering the soil with polyethylene. During the flowering period, it is enough to wipe the leaves with a damp cloth, because drops of moisture will leave brown spots on the petals.
During active growth, a set of buds and flowering gardenias, additional root dressing is necessary. It is best to start them in March, when the plant wakes up after the winter. Fertilizing continues with the beginning of autumn. Two feedings are enough per month.
For this purpose, it is better to need complex mineral fertilizers designed specifically for flowering plants. They must certainly have a sufficient amount of potassium and iron. The deficiency in the last substance can also be indicated by the appearance of unsightly yellow spots on the leaves. Flower crops are suitable liquid fertilizers for azaleas and orchids, sold in flower shops. It is only necessary to dilute them in a concentration two times weaker than indicated in the instructions for use of the product.
In the autumn and winter period, top dressing is carried out only if the gardenia has regained buds. It is also important to remember: products with calcium in this composition are not strictly recommended.
Disease Prevention and Pest Protection
The main preventive measure against diseases for gardenia is to provide her with competent care. The bush should be inspected regularly for pest infections. Dangerous enemies for a plant that can destroy it are:
- spider mite;
- scale insects.
If one of these pests has been “identified”, then gardenia must be set aside from other indoor plants in order to avoid infection. Gardenia is carefully treated with insecticides. For example, Fitoverm is well established. If the affected area is small, then one spray can be dispensed with. When pests actively breed, it will take several treatments over 10 days.
How to transplant gardenia
Flower transplant after purchase
After buying a plant, a transplant is necessary only if it is in a transport soil in which there are no nutrients. You can ask the seller about this. Most indoor flowers from abroad are sold in such unsuitable soil.
If the substrate meets the requirements, then you should wait until the gardenia adapts to new living conditions. This will take a couple of weeks. If the plant blooms, then you should wait for the fall of all flowers. For now, it will be enough to put it in a warm and bright place, providing the necessary care (including spraying).
For transplantation, they take a pot whose volume is several centimeters larger than the size of the root system. At its bottom, drainage is necessary. Gardenia loves acidic soil, so ready-made soil for growing azaleas is suitable for it. You can make a substrate yourself by mixing turf (or coniferous) soil with sand and peat in a ratio of 1: 1: 1. Gardenia is transplanted carefully, being careful not to damage the root system.
How to make gardenia bloom
To make a plant bloom, you need to think about what mistakes could be made in creating the conditions and caring for it. The most common ones are:
- Unsuitable temperature. The indoor thermometer should be above 18 ° C, but not more than 25 ° C.
- Sunlight deficit. Perhaps for gardenia it is better to choose a brighter place or provide additional lighting with the help of lamps.
- Lack of nutrients. Regular fertilizing with mineral complexes for decorative flowering plants should be organized.
- Poor water for irrigation. Water must be passed through the filter if it is too hard.
- Low humidity.
In most cases, the correction of growing conditions leads to the active formation of buds and flowering.
Mistakes when growing a flower
In addition to the errors that were listed above, novice flower growers often make others:
- Incorrect pot placement. Permanent shade or direct sunlight is harmful to the plant.
- Use hard, unsteady water or too cool for the plant.
- Lack of timely trimming.
- Failure to maintain the correct acid balance of the soil (it must be acidified regularly).
All this can lead to the fact that the appearance of the plant significantly deteriorate. Then the leaves will begin to turn yellow, fade and fall. Such gardenia will not only not bloom, but may also die sooner.
How to propagate gardenia
Growing gardenia in room conditions is not an easy, but very interesting task. The result of the work will certainly cause admiration, because these exquisite flowers can not leave indifferent. It is enough to take into account the needs of the flower in sunlight, warm air, moisture and nutrients. Plant care should begin from the moment of its acquisition.
