When to change pots and raise flowers, it is best to change pots and raise flowers according to the growth of flowers.

1. Generally, if you change pots to raise flowers, it should be based on the growth of flowers. If it grows quickly, it proves that the nutrients in the potted soil are still sufficient. If the dead seedling doesn't grow, it's best to change the pot at this time. Generally, it is enough to change the pot once every two to three years.

2. For our young plants, such as seeds for sowing, we should put them in small pots in the early stage and gradually change them into large pots in the later stage, especially grass flowers. It takes a very fast time to grow from a small seedling to a big seedling. According to its growth, if its roots grow full of pots soon, it is necessary to change pots in time, and finally plant them directly in a suitable big pot, and then let him grow and let him grow.

Therefore, there is no fixed time for changing pots. If the time is long, change the pot soil every 2-3 years. Most of its roots are full of pots, and the whole plant will obviously grow weakly. At this time, it is best to change the soil. For the newly planted seedlings, the pots should be gradually changed according to their growth performance and growth speed.

4. Potted flowers in the family, regardless of big seedlings, should remember that we should raise them with soil with good air permeability as much as possible. If the soil is garden soil, there will be less nutrients. If it is kept for a period of time, maybe six months to a year, the pot soil will harden, and if it is not poured thoroughly, there will be no nutrients in the pot soil, which will lead to its lack of nutrients and the emergence of stiff seedlings and yellow leaves. such

Because there is no need to change pots too frequently, he needs to be supplemented with nutrition. If nutrients are not supplemented, fertile soil will be short of nutrients for one year. If we plant any plant, we must fertilize it. Fertilizers should be selected according to the performance of plants. If it is high in phosphorus, multi-element growth or high in nitrogen, it can ensure that there is no shortage of nutrition. Potted soil only stores weak fertility. As long as there is a certain degree of looseness, its roots can grow well and quickly, so there will be no problem. This is that we must know when to change pots according to the situation, and then we can change pots reasonably, so that there is no difficulty in raising flowers. It's time to grow and blossom.
