How to fertilize gardenia correctly during flowering period

When the plant is growing poorly, even if it is already full of flower buds, it is necessary to give it some nutrients in time . Otherwise, the plant will not have enough nutrients to maintain flowering, the flowers will wither prematurely, and the fragrance will be weak.

1. Avoid applying nitrogen fertilizer during the bud stage

Special attention should be paid when fertilizing gardenia during the bud period . Not all fertilizers can be used. Otherwise, it will not only fail to promote flowering, but will affect flowering.

If too much nitrogen fertilizer is added during this stage, it will cause the plant to grow branches and leaves, causing a large number of flower buds to fall off , affecting the normal opening of the flowers.

2. Apply phosphorus and potassium fertilizers to promote flowering

Nitrogen fertilizer mainly promotes the growth of branches and leaves of plants, while phosphorus can promote flowering and fruiting. Plants will also consume a large amount of these elements when flowering, so phosphorus fertilizer should be the main fertilizer during the bud stage.

For example, you can apply some potassium dihydrogen phosphate solution to it, directly use the potassium dihydrogen phosphate diluted with water to water the roots, or you can apply fertilizer on the leaves, both of which can have a very good effect in promoting flowering.

3. Reasonably control the concentration of fertilizer and water

When fertilizing gardenia, try to apply small amounts of fertilizer frequently .

Especially when applying fertilizer after the flower buds grow, the concentration must be properly controlled, and it is best to add 1000-1500 times of clean water. If the fertilizer water is too concentrated, it is easy to cause fertilizer damage, which will also cause the flower buds to fall and shorten the flowering period.

4. Increasing light is conducive to flowering

Gardenia is relatively shade-tolerant, but it also needs sufficient light during its growth and flowering periods. Only under reasonable photosynthesis can the plant produce more nutrients for its growth and development.

  When there is insufficient light for a long time, the flower buds will be slow to bloom, and even if they bloom, there will be no very strong floral fragrance. Therefore, during the bud stage of the plant, it is appropriate to expose it to more scattered light, which can also play a very good role in promoting bud formation and flowering.
