The time of changing pots of Gladiolus should also be selected. After the period of vigorous growth, the period of withering flowers is more appropriate, which can reduce the impact on Gladiolus.
Before changing pots, gladiolus can first separate the flowerpot, loosen the surrounding soil, and then pour the flowerpot, take out Gladiolus with its roots with one hand, trim the roots properly, cut off the old and rotten roots on it, leave healthy roots, and ensure the function of absorption and transportation.
Every year there will be growth, so the flowerpot should be a little bigger than the original, to ensure that there is enough space to support the growth. The requirements for the soil are higher. Keep the soil free of caking. Use the sandy soil with nutrition to support the later growth. The selected soil contains nutrients, and it should be mixed with base fertilizer to maintain the growth demand in the later stage.
When these are ready, fill the pot with soil, and then plant Gladiolus in the middle. The planting depth shall be at least 5-8 cm, and the remaining soil shall be filled into the pot. After planting, pour enough water into it, which can play the role of planting, and maintain the temperature at about 20-25 ℃.
