1、 How to choose the fertilizer of oleander

If you want flowers to grow well, fertilization is the key, so how to fertilize oleander? First of all, we should choose the right fertilizer. As we all know, there are many kinds of fertilizers, including specially produced fertilizer and self-made farm fertilizer. It is not recommended to use chemical fertilizer for oleander fertilization. You can make farm manure by yourself: for example, animal manure and urine are rich in nitrogen, which can promote the growth of oleander plants. It is an indispensable fertilizer for growth and development, but you can't overdo it, which will make the flowers bloom. The principle of using this kind of fertilizer is thin, light, less and diligent to prevent the root from being burned; For example, animal bones are rich in phosphorus. Bones such as fish bones can be smashed or ground and used as base fertilizer for potting; Plant fertilizers such as peanut cake water or bean cake water are rich in potassium, which can be used as base fertilizer for potting or topdressing after fertilization

2、 Fertilization method of oleander

Oleander has a large plant and a long flowering period, so it is necessary to apply fertilizer. Fertilize at least twice a month before flowering; More phosphorus and potassium rich fertilizer should be applied at flowering stage, with topdressing every 10 days; It is best to apply fertilizer 1-2 times in winter. For potted oleander, sufficient base fertilizer should be applied when moving the pot in spring, and then topdressing is best once a week, which is rich in potassium and phosphorus. After the survival of oleander, the number of fertilization can be reduced. Remember not to apply more or only one kind

3、 Precautions for oleander fertilization

1. Oleander likes neutral or acidic soil. It's best not to use alkaline fertilizer such as plant ash when applying fertilizer

2. When transplanting potted plants, the soil in the flowerpot can be mixed with 15% chicken manure to keep the organic fertilizer at about 20%, not too much

3. When the temperature is high in summer, such as above 30 ℃, fertilization shall be suspended to avoid damage to oleander caused by fertilizer accumulation

4. The stems and leaves of oleander contain a variety of toxins. When applying fertilizer, be careful not to hurt the stems and leaves to avoid poisoning
