Spray some plant ash water, the leaves are thick and oily green, and the flowers rub against the open pot

Plant ash is the ash formed after plant combustion. It is rich in potassium, phosphorus, calcium and minerals. It is not only a high-quality foliar fertilizer, but also can effectively control the occurrence of diseases and pests

1. What are the suitable flowers

Because plant ash is alkaline, it is not suitable for acidic flowers, such as azalea, camellia and other southern flowers and plants

2. When

In case of defoliation and yellowing of flowers, aphids, red spiders and other diseases and pests, plant ash water can be sprayed on the leaf surface, which can improve the yellowing of leaves and effectively control diseases and pests

3. How

After 12-16 hours, put the grass and trees into the fresh ash pot, and then spray the ash on the upper layer with a stick. After that, put it into the fresh ash pot, and then spray it fully

Note that the ratio of plant ash to water is different for different situations. When defoliation occurs, the dilution ratio is 1:10; When spraying before and after flowering, the dilution ratio was 1:2; When killing insects, the dilution ratio is 1:20

4. Spraying frequency

Spray once a week. After spraying 2-3 times continuously, the yellow leaf phenomenon can be improved and the diseases and pests can be controlled

Spray some potassium dihydrogen phosphate, the branches are strong, the leaves are green, and the flowers are blooming and colorful

Potassium dihydrogen phosphate is a good fertilizer for raising flowers. Spraying it on the leaves can supplement phosphorus and potassium to the flowers, promote photosynthesis and make the flowers grow

2. When

It can be in the growth period and pregnant bud period of flowers, which can make the branches stronger, the leaves fat and green, and the flowers bloom more and more colorful

Add clean water into the potassium dihydrogen phosphate solution. The water temperature should not be too low. The dilution ratio is 1:3000. Put the dilution into the watering can and spray it towards the leaf surface. Pay attention to spraying the back and tip of the leaf

4. Spraying frequency

Spray 2-3 times in the bud pregnancy period of the flower, which can make the flower bloom more and colorful

Spray some ferrous sulfate, the leaves are green and the flowers are delicate

Ferrous sulfate is rich in iron, which can promote the formation of chlorophyll and adjust the pH of soil. Spraying it on the leaf surface is better than pouring it into the soil

1. What are the suitable flowers

Suitable for flowers that like acidic soil, such as jasmine, camellia, azalea, etc

2. When

When the leaves of Camellia and Rhododendron turn yellow due to the weakening acidity of the basin soil, ferrous sulfate can be sprayed. It is best to spray it in the morning and evening on a sunny day

3. How

If ferrous sulfate turns yellow, it indicates that it has been oxidized and deteriorated. Green ferrous sulfate should be used. Add clean water to ferrous sulfate, the water temperature is close to the room temperature, and the dilution ratio is 1:1000. Put the diluent into the watering can and spray it on the leaf surface

4. Spraying frequency

Spray the leaves once a week for 3 weeks, and then continue spraying every other month. Spraying too often is harmful to the flowers
