Rhododendron leaves are yellow and small, so something should be fed

Hello, azaleas are taboo exposed to the sun, and if they are in a high-temperature, dry, and poorly ventilated environment for a long time, it will cause the leaves you said to dry up and turn yellow and fall off in a large area.

It is best to put this pot of rhododendrons in a semi-shaded place where the sun is not exposed to the sun, azaleas prefer water, you can keep the potting soil moist during the growing season, and you can often spray the rhododendron leaves and trunks on sunny days, which can increase the humidity of the air. After the rhododendron blooms, properly prune off the thin and elongated branches, and apply compound fertilizer or nitrogen fertilizer once every month or half a month during the growth period, which is conducive to the occurrence of more lateral branches after pruning and makes the branches thick. After the early autumn season, the phosphorus fertilizer (catalytic bud pregnancy) is also applied once every half a month or once a month until the flower buds bloom and the fertilization is stopped.

In the process of maintenance, if you find that the leaves become smaller and curl back, you should pay attention to insect pests, rhododendrons are easy to give birth to red spiders and mites, regularly spray insecticides and fungicides on both sides of the leaves, as well as ** lobular disease drugs, this kind of drugs are sold in the flower market. If you find that the disease is sick, it is best to spray 3 times in a row, once every 7 days.

If you follow these methods to take care of your azaleas, you should be able to take care of your azaleas, good luck.

The effect of applying potassium sulfate compound fertilizer or diamine phosphate is good, and the two I have been using can be turned into water to water to water the flowers, and the thin fertilizer is applied frequently. You can also poke a few small holes in the side of the pot and place the fat grains inside the small holes. Put 4-5 grains in a hole is fine.

Depending on the size of the pot, 3-5 holes. Later, look at the growth and then top dressing. It is possible to combine the two methods.

First, the base fertilizer.

The base fertilizer is generally incorporated into the substrate when the rhododendron is planted or repotted, and the compound fertilizer with a balanced ratio of nitrogen, phosphorus and potassium is usually selected. The fertilizer should not be too thick, because the plants at this time need to slow down the seedlings, and the thick fertilizer will be detrimental to their growth, so it should be diluted before use.

2. Fertilize before flowering.

Before flowering, adequate fertilizer can increase the number of flowers and will also help with flowering quality. At this time, the fertilization is mainly phosphate fertilizer, and a small amount of potassium fertilizer is added to improve the resistance of the plant. Applying less or no nitrogen fertilizer, otherwise it will make it grow and hinder flowering.

3. Fertilization during flowering.

Fertilization is generally not required during flowering, when it absorbs nutrients from the soil and requires less additional fertilizer. Improper fertilization can lead to shortened flowering and even wilting of flower buds.

Fourth, fertilize after flowering.

After flowering is another important time period for fertilization. Since rhododendron flowering consumes a lot of nutrients, it needs to be supplemented with a certain amount of nitrogen fertilizer. In the summer, it enters a semi-dormant period, at which point no fertilization is required.

But in August-September, it will resume growth, at which point phosphorus fertilizer should be applied every 15 days. Stop fertilizing after winter.
