Osmanthus, as one of China's traditional famous flowers, is deeply loved by people for its unique fragrance and beautiful flowers. To ensure the osmanthus tree grows strong and blooms profusely, fertilization is a key step. This article will provide a detailed analysis of the techniques for fertilizing osmanthus during its leaf growth period to help you cultivate a lush osmanthus tree.
Time for Fertilizing Osmanthus for Leaf Growth
The period when osmanthus is growing leaves is a crucial time for fertilization. Fertilizing during this period can be divided into the following stages:
1. Spring Fertilization: Spring is the first peak growth period for osmanthus. Fertilizing at this time can promote the growth of new branches and leaves. The application is generally done before the osmanthus buds in spring, typically from late February to early March each year.
2. Summer Fertilization: In summer, the temperature is high, and osmanthus grows vigorously, requiring nutrient supplementation. Fertilization is generally done from late May to early June each year.
3. Autumn Fertilization: Autumn is the second peak growth period for osmanthus. Fertilizing at this time can promote flowering. The application is generally done from late August to early September each year.
Fertilizer Selection for Osmanthus Leaf Growth
The selection of fertilizers for osmanthus during leaf growth depends on the growth stage of the plant and the soil fertility. Here are some suitable fertilizers:
1. Organic Fertilizers: Organic fertilizers such as chicken manure, cow manure, and pig manure are rich in organic matter and nutrients, which are beneficial for osmanthus growth. When applying, ensure the organic fertilizers are fully decomposed.
2. Compound Fertilizers: Compound fertilizers contain multiple nutrient elements such as nitrogen, phosphorus, and potassium, which can meet the growth needs of osmanthus. Apply according to the recommended dosage on the fertilizer packaging.
3. Trace Element Fertilizers: Trace element fertilizers such as zinc sulfate and boric acid can supplement the trace elements needed during osmanthus growth. Apply according to the recommended dosage on the fertilizer packaging.
Fertilizing Methods for Osmanthus Leaf Growth
The main methods for fertilizing osmanthus during leaf growth are as follows:
1. Basal Fertilization: Before spring fertilization, apply organic fertilizer or compound fertilizer around the base of the osmanthus tree to a depth of about 10-15 cm.
2. Top-dressing: During the vigorous growth period of osmanthus, top-dressing can be applied. Top-dressing can be done through foliar spray application at a concentration of 0.1%-0.2%.
3. Liquid Application: During the vigorous growth period of osmanthus, fertilization can be done by liquid application. For this method, dissolve the fertilizer in water and apply it evenly around the base of the osmanthus tree.
Precautions for Fertilizing Osmanthus Leaf Growth
1. Avoid excessive fertilization: Over-fertilization can lead to poor growth or even death of the osmanthus tree. When fertilizing, apply an appropriate amount based on the size and growth stage of the tree.
2. Avoid fertilizing too early: Fertilizing too early can affect osmanthus growth and even cause root burn. The best time to apply fertilizer is before the buds sprout.
3. Water after fertilizing: Water promptly after applying fertilizer to help it dissolve and be absorbed by the plant.
Fertilizing osmanthus during leaf growth is a key step in ensuring its healthy growth. Mastering the right timing, fertilizer selection, and application methods can effectively promote osmanthus growth, making your tree lush and vibrant. We hope this article is helpful to you and that you cultivate a beautiful osmanthus tree!
