Gardenia is an evergreen shrub with white and elegant flowers, evergreen leaves and fresh and pleasant flowers. It is an important garden ornamental plant. Gardenia is not only beautiful in appearance, but also can be used as medicine, which has the effect of clearing away heat and toxic materials. The flower language of gardenia is eternal love, which is often used to express love. In the process of gardenia cultivation, it is often necessary to prune it to promote its growth. So how to do it? Let's have a look.

First, pruning method

1. Trimming time

Pruning gardenias is generally carried out in spring and autumn with good weather conditions. Gardenia grows fast, so it is very necessary to prune it in time. Proper pruning can promote the healthy growth of gardenia. Pruning in spring and autumn with suitable temperature and humidity conditions can reduce the adverse effects on gardenia.

2. Leave the three main branches

When pruning, first choose three main branches, which need to be preserved. Then cut off all the side branches that grow up to 15 cm from the base of these three branches, so that the side branches are concentrated above the middle of the main branch. Also pay attention to cutting off the branches that grow from the roots.

Cut off the fragile branches.

Pay attention to cut off the branches and leaves that are not growing well, and don't leave the branches and leaves infected by pests and diseases. Poor growth of branches and leaves will take away the nutrients in Jiankang branches and leaves, which is not conducive to the healthy growth of plants; Leaves damaged by pests and diseases will also threaten healthy leaves.

Cut off long branches

When gardenia is in a vigorous growth period, cutting branches and leaves is beneficial to the growth of gardenia. The main reason is that pruning long branches can promote the growth of lateral branches and make plants bloom more.

Remove flower buds

Take off the buds properly, leaving only 2~3 buds on the robust branches, and only 1 bud or none on the poorly growing branches.

Second, matters needing attention

1. Pay attention to ventilation

Gardenia likes light and is more drought-tolerant. Gardenia can be placed outdoors for ventilation after pruning, which is beneficial to its growth and recovery.

2. Water and fertilizer management

When gardenia soil is dry, we should pay attention to watering to promote its recovery. Pay attention to dry water when watering, and try not to pour it into the incision. Also pay attention to the timely fertilization of gardenia, choose nutrient solution when fertilizing, and add some nutrient solution when watering.

3. Control pests and diseases

After pruning, gardenias should be sprayed with fungicides. This is because many cuts will be left on the plants after pruning, and the resistance of the plants after pruning is weak, which makes it easy for germs to take advantage of it. Therefore, every time you prune, you should spray bactericidal drugs.
