Raw materials: controlled release fertilizer, water-soluble fertilizer, fermented chicken manure, potassium dihydrogen phosphate.

Steps:

The first step: planting Chinese rose for the first time, it is best to choose winter every year, and the seedlings are relatively large. Choose organic fertilizer and pine scale peat and mix well, and put about 20 to 50 grams of fermented chicken manure in every 20 cm pot. Organic fertilizers such as bone meal, cake fertilizer and fermented sheep manure can also be mixed, but the overall dosage should not be too much.

Step 2: Slow release fertilizer can be added at the same time as organic fertilizer, and the dosage is basically 4 grams per liter of soil. The dosage of a gallon of basin is about 12g. It can also be directly sprinkled on the surface of the planted rose soil layer, but the dosage should be halved.

Step 3: Daily maintenance can be watered with fertilizer with the ratio of nitrogen, phosphorus and potassium of 20-20-20, and the ratio is usually 1 g fertilizer plus 1 kg water.

Step 4: At flowering stage, potassium dihydrogen phosphate can be applied to promote flowering. The basic usage is to irrigate with 1500 times potassium dihydrogen phosphate solution before and just after flowering.

Step 5: Fertilizers such as fish intestines at home can be buried in a small amount to promote flowers.
