I don't know why the leaves and buds of the blooming dragon boat flower have withered.

The leaves and buds of the flowering dragon boat flowers have withered, which is caused by high temperature and little watering. The main points of culture are as follows:

It is best to choose fertile, loose and well-drained acidic sandy soil for the Dragon Boat Festival. If it is potted, it is best to use a mixture of cultivated soil, peat soil and coarse sand.

Watering dragon boat flowers likes being wet and afraid of being dry. The stem and leaf growth period needs enough water to keep the basin soil moist, which is beneficial to bud germination and leaf growth.

Sunshine Dragon Boat Flowers need plenty of sunshine, especially in the growing period of stems and leaves. Adequate sunshine, green and shiny leaves, is conducive to the formation of inflorescences, neat flowers, bright colors.

Temperature The optimum temperature for the growth of Dracaena dracunculata is 15-25℃, 24-30℃ from March to September, and 13- 18℃ from September to next March. In winter, the temperature is not lower than 0℃, so it is vulnerable to freezing injury.

In the growth period of fertilization, apply 1 time every half month, and mix nitrogen, phosphorus, potassium, ferrous sulfate and horseshoe slices at the ratio of1:1:2: 3.

Pruning and pruning are mostly carried out after leaving the house in spring, mainly by thinning branches properly to facilitate ventilation and lighting. In addition, proper enucleation during flowering can make it more pregnant and flowering.

Leaf spot and anthracnose do great harm to the insect, and it can be sprayed with 10% antibacterial agent 40 1 acetic acid solution 1000 times.
