As winter approaches, many flower enthusiasts begin to prepare their cassia for the winter. As a traditional ornamental plant in China, cassia not only has a fragrant aroma but also has certain medicinal values. If you want to keep cassia safe during the cold winter, proper fertilization is the key. This article will introduce you to the method of fertilizing cassia for overwintering in detail, helping you easily care for your cassia.
Cassia grows slowly in winter, even in a state of dormancy. The purpose of fertilizing at this time is to store nutrients and improve the plant's cold resistance. Proper fertilization can not only ensure that cassia survives the winter safely but also provide sufficient nutrition for flowering in the following year. Next, let's take a detailed look at the method of fertilizing cassia for overwintering.
Cassia overwintering fertilization timeThe best time for cassia overwintering fertilization is generally in autumn, about one month before the leaves fall, when the cassia is in the peak growth period. Fertilization can effectively promote plant growth and improve cold resistance.
Cassia overwintering fertilization method1. Type of fertilizer
Cassia overwintering fertilization mainly uses organic fertilizers such as chicken manure, cow dung, and sheep dung. Organic fertilizers are rich in organic matter and trace elements, which are beneficial to cassia growth. A moderate amount of compound fertilizer can also be applied to supplement the required nutrients like nitrogen, phosphorus, and potassium for the plant.
2. Fertilizer amount
The amount of fertilizer for cassia overwintering fertilization should be determined based on the size and growth condition of the plant. Mature cassia should be fertilized 2-3 times a year, with each application being about 100-200 grams. For seedlings or newly planted cassia, the amount of fertilizer should be appropriately reduced.
3. Fertilization method
(1) Ditch fertilization: Dig a ditch around the cassia roots, evenly sprinkle the fertilizer into the ditch, and then cover with soil. Note that when fertilizing, avoid direct contact between the fertilizer and the roots to prevent root burning.
(2) Broadcast fertilization: Evenly sprinkle the fertilizer around the cassia and gently turn it into the soil. This method is suitable for a smaller amount of fertilizer.
Precautions1. After fertilizing, water thoroughly to ensure the fertilizer is absorbed by the soil.
2. Keep the soil moist after fertilizing to prevent fertilizer evaporation due to drought.
3. When fertilizing, pay attention to the growth condition of the cassia and adjust the fertilizer amount as needed.
Cassia overwintering fertilization is a key link to ensure the safe overwintering of cassia. Through proper fertilization, it can provide sufficient nutrition for cassia and improve its cold resistance. I hope the introduction in this article can be helpful to you in caring for your cassia.
