Begonia flowers are not good for them to grow in cool places. However, in the hot summer, it must be properly shaded to prevent the sun from burning flowers and leaves.

Soil requirements of potted crabapple flowers

The growth of begonia flowers requires relatively loose alkaline soil, which can be added to the soil at the bottom of the tree root or to the river sand. The depth of potted sea bream flower should not be too deep, which is beneficial to extend the root system better. It can be based on the size of the plant, usually 12 centimeters from the basin.

Nutrient requirements of potted snapper

In spring, when sprouting, some organic fertilizer should be applied to supplement nutrition. After fertilization, water should be watered once to promote plant growth. When autumn leaves are like spring, fertilize. Thanks to the jellyfish after flowering, the need to apply phosphorus and potassium fertilizer. Under normal circumstances, some special jellyfish fertilizers can be used.

Water requirements of potted crabapple flowers

Crabapple flowers like a wet environment. When watering, it is better to keep the soil moist, watering in summer and not watering in winter. Avoid rain so as not to cause too much root water.

Pruning methods of potted sea bream flowers

In order to ensure the better growth and flowering of begonia, it is necessary to prune branches and leaves in early spring after the leaves of begonia, cut off weak branches, diseased branches, long branches and dense branches. Sparse parts according to the specific situation. Cut and promote more branches.

Temperature requirements of potted crabapple flowers

Begonia flowers are hardy and like ventilation. Crabapple flowers can usually be placed in a ventilated place, such as a yard or balcony. If the temperature is very low in winter. It is necessary to take appropriate protective measures.

Pest of crabapple flower and its control

Begonia flower pest: aphids

Introduction of tsutsugamushi disease

Aphids are common plant pests. Aphids can damage green leaves and leaves, suck juice, cause new buds to stop growing, leaves seem to twist and contract, and also bring coal pollution and viral diseases, which are prone to disease in the spring. It usually occurs in early April, decreases gradually after mid-June, and begins to increase after mid-August until the leaves end.

Control methods of locusts

The most direct way is to cut off branches with pests. It can also be controlled by imidacloprid water dispersant, high efficiency cyhalothrin water emulsion, butyl thiocarbamate EC, acetamiprid water dispersant and so on. Please note that these drugs are not suitable for early spring.

Crabapple flower pest: thrips

Introduction of hippocampus

Begonia flower pest: net bug

Brief introduction of net disease

Net mites often hide behind the leaves to suck the juice of the veins, the front of the leaves will appear pale spots, gradually become patches, the back of the leaves will rust, thicken, and eventually lead to fallen leaves, in serious cases will cause the leaves to fall off or bloom for a good time.

Network prevention and treatment methods

The net has a relatively fragile life and can be sprayed with general pesticides. It can be combined with acetamiprid water dispersant, cyhalothrin water emulsion, imidacloprid water dispersant, fenvalerate EC, avermectin EC and so on.

Thrips can cause great damage to branches and branches, especially tender tips. In the early stages of the disease, because the buds did not unfold, the Hummer hid inside and sucked juice, which was not easy to find. At the end of the disease, the young leaves turn yellowish brown and greasy, and gradually wither. Just like being burned, they are often mistaken for drought or lack of water or sunburn. Hummers are resistant to high temperatures and usually appear in early May. The most serious damage is from July to August.

Prevention and treatment of Hummer

The most direct way is to talk about buds, which can control the disease in a short period of time. It can also be controlled by acetamiprid water dispersant, imidacloprid water dispersant doubling solution, pyrazide wettable powder or nitropyran aqueous solution.

Begonia flower pest: stem wasp

Introduction to dry Bee Disease

The larvae of the stem can harm the buds and lead to the death of the treetops. Adults of dry bees usually begin to lay eggs in late April every year. From late April to early May, the larvae began to feed on young branches, resulting in sagging and death of buds. The branch was damaged two years ago and stayed until September. .

Dry bee control method

Cut the branches of the bedding directly. It can also be controlled by avermectin emulsifiable concentrate, chlorpyrifos soluble powder, butyl thiocarbamate emulsifiable concentrate, 3% hyperosmotic phenoxy emulsifiable concentrate 1, etc.

Crabapple flower pest: longicorn beetle

Brief introduction of beetle disease

Beetles usually live in trees for three years. In the first two years, the larvae will feed on the trees, and in the third year they will appear and mate and lay eggs. It is one of the most important dry and destructive pests.

Control methods of longicorn beetles

In the middle and late May of each year, cypermethrin-cut microcapsules (Green Wiley) were sprayed near the trunk and branch points according to the beetle's hole to kill the adult worms and spray them for another 50 days after 40 days. For the beetle larvae in the trunk, 5 times of dichlorvos emulsified concentrate or chlorpyrifos EC was artificially injected and sealed with the soil to kill the larvae. For planted seedlings, natural enemies can be released from tubers, and in severe cases, tuberculosis can be carried by swollen bees.

Crabapple flower pest: red spider

Brief introduction of Red Spider Disease

The damage degree of red spider disease is closely related to climate and planting density. It is the most serious in arid areas and intensive planting. Red spiders mainly harm old leaves, usually parasitic on the back. Larvae, nymphs and adults will suck the sap from the back of the leaves, making the leaves white and chlorotic. In serious cases, it is grayish white, and eventually the leaves fall off a lot.

Control method of red spider

It can be controlled by medicinal plants, such as eucalyptus emulsifiable concentrate, thiazolone EC, snail, styrene-butadiene EC, triazolyl WP and 2 pairs of hyperthyroidism WP.

Begonia flower pest: Spodoptera litura

Introduction to moth disease

Moths have many thorns on their bodies. If you accidentally touch it, it will cause redness and pain, which will be very difficult. If it is serious, it can cause lymphatic inflammation. Moth larvae feed on the meat on the back of the old leaves, leaving transparent reticular veins. The older larvae feed on all the leaves. Moths are a group of eating organisms that often gather together to cause damage to leaves. It usually occurs in June, with the worst from August to September.

Control methods of diamondback moth

It can be controlled by high efficiency cypermethrin aqueous emulsion, fenvalerate EC, avermectin EC, citalate EC and phoxim EC.

Pruning methods of crabapple flowers

Spring pruning

In spring, crabapple flowers begin to sprout, which requires a lot of nutrition. It is necessary to cut off dead branches, weak branches, diseased branches, horizontal branches, stacked branches, and too many branches of begonia flowers in order to promote the germination of begonia flowers. Promote the growth of new buds. Note that some long branches and leaves need to be cut according to the shape of jellyfish flowers to promote branching, increase the number of flower branches, and ensure that flowers are unique in the coming year.

Pruning after flowering

The growth periods of different varieties of begonia are different. According to the different flowering stages of begonia, the leaves and leaves of begonia were pruned two weeks after flowering. Cut crowded branches and protruding branches. Long branches can be truncated to keep 3 to 4 branches shooting out from the base. This helps to increase the number of short branches that form buds.

Pruning after falling leaves

After the leaves of jellyfish flowers, in order to better grow winter buds and maintain winter nutrition, such as dead branches, weak branches, diseased branches, cross branches, stacked branches, and too many branches of begonia should cut flowers in spring. At the same time, pay attention to maintaining the overall shape of the jellyfish.
