Techniques of flower cultivation and fertilization in autumn

Selection of fertilizer

Teach students according to their aptitude and apply fertilizer according to their planting. The method is very simple. For those plants that bloom in autumn, in order to ensure beautiful flowers, fertilization focuses on supplementing phosphate fertilizer and potassium fertilizer; Plants that grow normally in the growth period in autumn need more nutrients. They should be watered with some thin fertilizer and water, or some rotten farmyard fertilizer. For foliage plants in the growth period, add a little nitrogen fertilizer appropriately; For plants that slowly enter dormancy from autumn, appropriately reduce the content of nitrogen fertilizer to avoid affecting overwintering; For bulbous plants and aromatic plants, a little phosphorus fertilizer and potassium fertilizer can be applied appropriately

Fertilization cycle

Flower fertilization needs to grasp the amount of fertilizer and carry out according to a certain cycle. Fertilization in autumn should follow the principle of thin fertilizer and frequent application. The amount of fertilization should be less each time, but it can be applied several times more

In early autumn, when plants are still growing, they should be watered once every 7-10 days. With the gradual deepening of autumn, the temperature drops, and the growth of plants slows down. They should be fertilized once every 15-20 days and gradually stop fertilizing

Fertilization techniques

In autumn, some plants begin to grow for the second time, and some plants enter the flowering season. Similarly, some plants enter the growth slowdown period. The time of fertilization should be determined according to the growth status of plants

For plants in the growing period, the purpose of fertilization is to promote the growth of plants, and the nutrients in the soil should be supplemented in time through fertilizer; For autumn flowering plants, the main purpose of fertilization is to promote flowering, and more fertilizer can be applied to promote flowering; For plants that are already in the slow growth period, we should protect and reduce fertilization in autumn

Precautions for fertilization in autumn

Acidity and alkalinity

People should not be unfamiliar with this word. Yes, different plants need different fertilizers and have different acidity and alkalinity. They like acidic plants and avoid using alkaline fertilizers when applying fertilizer. They can choose calcium superphosphate

Growth cycle

This is what Xiaobian repeatedly stressed in the article. The growth state of flowers is different, and the requirements for fertilizer are also different. The specific fertilization operation should be determined according to the actual situation
