Gardenia is a tropical plant that does not have a very good reputation for being grown at home.
The main methods of propagation of gardenia are by seeds and cuttings. It should be noted right away that at home the seed method is almost hopeless.
The process of growing gardenia seeds is quite painstaking, since this plant has a capricious character. But if you have patience, you can grow a flower in this way. And the plant will delight you with its delicate aroma and luxurious flowers.
When does it multiply?
The last days of February are considered the best period for sowing seeds. - the beginning of March, when it gets warmer, and the day increases significantly. The germination period of planting material from the moment of sowing is 1-1.5 months. Before this, the earth must be warmed up. It is allowed to sow seeds in summer. But here an important condition is to prevent overheating of the sprouted seedlings, otherwise it will dry out.
How to get planting material?
If you plan to purchase seeds for growing, then it is better to do this in specialized flower shops. But you can assemble them yourself. It must be borne in mind that the seed box appears after flowering, which lasts from March to September.
The seeds are oval in shape. They have one rounded end, the other sharp. On average, they grow in length up to 4-5 mm. Fresh high quality seeds are colored light and dark brown. After they are collected, you must dry them well. Shelf life is 2-3 years, if stored in a dry place without moisture.
The most important indicator on which the germination of seedlings depends is the freshness of the seed. When buying, be sure to check the packaging date. It often happens that out of 5 pieces, 1-2 emerge.
Important! Gardenia seeds are poisonous. When working with them, you must use personal protective equipment.
The preparatory stage consists in preparing:
- fresh gardenia seeds;
- shallow wide container or pot;
- potting soil.
The substrate can be a ready-made mixture for azaleas or a suitable soil prepared independently. In order to get it, you need to mix in the same proportions:
- coniferous or deciduous land;
Seeds should be soaked 24 hours before sowing in warm boiled water, per 100 ml of which 1-3 drops of a growth stimulant are added.
How to grow a flower?
Large gardenia seeds in order not to carry out a pick in the future, you can put it in separate cups one by one... But most often, flower growers sow them in a common container.
- The first step is to prepare warm soil. You can find out more about soil and fertilizers for a flower here.
- A 4-5 centimeter drainage layer of fine sand is laid on the bottom of the container, on top of which prepared earth is poured.
- Water it and spread the seeds on top. It is more accurate and more convenient to work with tweezers. Seeds are laid out from each other at a distance of 3-4 cm.
- The soil should be slightly compacted and watered with a spray bottle.
- Until the moment when shoots appear, the container must be placed in a warm and dark place. The temperature should be + 23 ° С, do not fall below + 18 ° С.
- To create greenhouse conditions, cover with a bag or plastic bottle. We must not forget to air every day, to remove the collected condensate.
The seeds will germinate in about a month. After that, the containers must be placed in a lighted place, but so that direct rays of the sun do not fall on them.
Sometimes, on some sprouts, a shell remains, which prevents the seedling from developing. Its rapid separation is facilitated by high humidity. Florists advise to wrap the seed coat with wet cotton wool, and then gently pull it off. Seedlings appear at home no earlier than a month later. If the process of reproduction by seeds will be carried out in winter, then additional lighting must be provided.

What to do after landing?
- After the second pair of leaves appears on the seedlings, it is necessary to plant it in different pots, that is, perform the picking procedure. In terms of volume, they should be 2-3 cm more than the soil food, with which the flower will be transplanted. You will get acquainted with all the features of a competent gardenia transplant in a separate article.
- Since these gardenia sprouts are not yet accustomed to room conditions, to maintain the desired microclimate, they must be covered with plastic bottles.
- After a month, they are removed and the gardenia is fed for the first time. The concentration of fertilizers used should be two times weaker than that indicated in the instructions.
- For the prevention of chlorosis, it is recommended to spray the leaves with Ferovit every 10 days.
- After the appearance of new leaves, gardenia must be regularly fed with complex fertilizers without the presence of hydrochloric acid salts and carbonates in them. In this case, the doses should be reduced by a third. Top dressing is carried out 2-3 times a month. We described all the features of the choice of fertilizers and soil for gardenia here.
- Water the gardenia flower with soft water.
- If you pinch the upper stems, then the bush will become more voluminous.
- After a year, it is advisable to place the flower in another place. Then he is looked after as an adult plant.
Common mistakes and tips
Blunders can cause certain problems. The appearance of yellowness on the leaves indicates that the soil is not acidic enough. To prevent this from happening, it is advised to constantly add lemon juice to the water. Florists recommend adding 4-5 drops of lemon juice to 1 liter of water. The juice can be replaced with citric acid.
If at home, the gardenia begins to turn yellow and fly around the foliage, then the reason may be hiding in a lack of moisture or watering the flower with cool water.
Leaves become pale due to:
- lack of light;
- improper temperature;
- deficiency of nutrients in the soil.
The flower needs to be rearranged to a more illuminated place and fertilized into the ground. Signs such as wilting leaves, shedding buds and flowers indicate that the air temperature is not high enough. Gardenia loses its beautiful appearance if it stands in a draft, as well as from excess moisture.
Improper care and lack of proper attention to the flower can lead to the appearance of pests and the development of diseases:
- If gray dots or depressions similar to needle holes appear on the upper leaves, then the plant is suffering from thrips.
- The thyroid gland leaves brown oval spots above and below the leaves.
- Spider mites will cause them to dry out, and cobwebs will be visible on their underside.
- It is not uncommon to see a sticky discharge on the gardenia. This is the result of the vital activity of aphids, which are very fond of the tops of the stems and buds.
- Gardenia can suffer from mealybugs, due to which:
- the plant begins to grow poorly;
- leaves turn yellow and fly around (you can find out about other problems with gardenia leaves here);
- flowering stops.
It is imperative to fight pests, because exceptionally healthy plants grow, bloom and reproduce well. You can get rid of insects with insecticides.
