With the improvement of living standards, more and more people have started to care for potted plants at home, and osmanthus, due to its unique fragrance and beautiful form, has become a favorite of many gardening enthusiasts. To ensure the robust growth of potted osmanthus, proper fertilization is key. What kind of fertilizer should be used for potted osmanthus? This article will reveal the secrets of fertilizing osmanthus.
Understanding the growth habits of potted osmanthusBefore discussing the fertilization of osmanthus, let's first understand the growth habits of potted osmanthus. Osmanthus prefers a warm and humid environment, is not cold-resistant, and grows well in loose, well-drained soil. Understanding these habits helps us choose the right fertilizer.
Principles of fertilization for osmanthus1. Moderate fertilization: Over-fertilization can lead to soil salinization, affecting the growth of osmanthus. Fertilization should follow the principle of "frequent application of light fertilizer."
2. Timely fertilization: Osmanthus has a higher demand for fertilizer during its vigorous growth period and flowering period, and the fertilization amount should be increased appropriately during these times.
3. Choosing the right fertilizer: According to the needs of osmanthus, choose compound fertilizers rich in nitrogen, phosphorus, and potassium.
What kind of fertilizer to use for potted osmanthus1. Organic fertilizers: Organic fertilizers such as chicken manure, cow dung, and sheep dung are rich in organic matter and trace elements, which help improve soil structure and increase soil fertility. However, it is important to note that organic fertilizers need to be fully decomposed before use to avoid root burning.
2. Compound fertilizers: Compound fertilizers contain multiple nutrients such as nitrogen, phosphorus, and potassium, which are suitable for the growth of osmanthus. Common compound fertilizers on the market include urea, diammonium phosphate, and potassium sulfate.
3. Trace element fertilizers: Osmanthus also has a high demand for trace elements such as boron, zinc, and iron during its growth, which can be supplemented with trace element fertilizers.
4. Foliar spraying: During the vigorous growth period and flowering period of osmanthus, foliar spraying can be performed to supplement nutrients. Foliar spray fertilizers include potassium dihydrogen phosphate and zinc sulfate.
Fertilization timing and methods1. Fertilization timing: Spring is the vigorous growth period of osmanthus, and the fertilization amount can be increased appropriately; in summer, high temperatures should reduce fertilization; autumn is the flowering period of osmanthus, requiring an increase in phosphorus and potassium fertilizers; and in winter, low temperatures should stop fertilization.
2. Fertilization methods: Spread the fertilizer evenly on the surface of the potting soil, then cover it with fine soil, or apply the fertilizer directly into the potting soil. When foliar spraying, ensure even application and avoid fertilizer dripping.
Proper fertilization is key to ensuring the healthy growth of potted osmanthus. Understanding the growth habits of osmanthus, following fertilization principles, choosing the right fertilizer, and fertilizing at the right time and amount will allow your potted osmanthus to bloom with a captivating fragrance.
