How to raise hibiscus flowers and pictures of hibiscus flowers

1, fertilizer: hibiscus flowers are large, so the requirements for fertilizer are relatively high. The potted soil we use for cultivation can be mixed with garden soil, compost and river sand in the ratio of 6:3: 1, or can be cultivated with compound fertilizer, floating sand or perlite mixed with phosphorus and nitrogen.

2, light moisturizing: hibiscus flowers must maintain sufficient light during the maintenance period, and it is not easy to bloom in a hidden environment. It needs a lot of water, so it needs to ensure enough water, which will affect its growth in a dry environment.

3. Winter maintenance: hibiscus flowers will die on the ground in winter, and the underground part will spend the winter in the form of roots. If it is indoor maintenance, we suggest that the room temperature should be kept above 10 degrees, so that it can safely overwinter; If it is a relatively cold environment of about 0 degrees, it is necessary to completely stop fertilization, control watering, cut off dead parts, and let it go through the winter smoothly.

Extended data:

Hibiscus pest control;

1, powdery mildew: white powdery small spots appeared on the leaves at the early stage of the disease, and many small spots merged into large spots at the later stage. When the damage is serious, the plant is weak, the leaves are yellow and fall off early. Prevention and control methods: Spraying 25% triadimefon 2 000~2 500 times at the initial stage of the disease, or spraying 50% sulfur powder when the dew is still wet in the morning.

2. Cicadellidae: Adults and nymphs suck juice from buds, leaves and twigs, which leads to the gradual death of branches and is harmful to health. Prevention and control methods: Apply chemicals to branches before adults lay eggs at the end of September to prevent them from laying eggs. Spraying 500-fold solution of 50% carbaryl or 2000-fold solution of 2.5% deltamethrin during the nymph damage period. ?

3. Tetranychus cinnabarinus: Harming plant leaves. The damaged leaves showed yellow and white spots at first, and then gradually spread to the whole leaves, causing the leaves to curl, yellow and fall off. Control method: spray 40% omethoate 1 000~5 000 times solution. Aim at the back of the blade when spraying, and pay attention to the spraying cavity and the middle and lower blades.
