Overview of fertilization for osmanthus trees

Osmanthus fragrans is an evergreen broad-leaved tree that prefers warmth and humidity. The most suitable growth temperature is 15-28℃.

Osmanthus likes fertilizer. Try not to use chemical fertilizers. Use more farmyard manure. It especially likes pig manure fertilizer. You can use decomposed cake fertilizer liquid. Fertilize in thin layers and apply frequently. Starting from February, water it once every 10 to 15 days. The fertilizer should not be concentrated and the amount should not be too much.

What fertilizer is good for osmanthus trees?

Before planting osmanthus in the ground, herb ash and organic fertilizer should be mixed into the tree hole first, and watered thoroughly once after planting. Generally, nitrogen fertilizer is applied once in spring, phosphorus and potassium fertilizers are applied once in summer to make the flowers flourish and the leaves luxuriant, and wintering organic fertilizer is applied once before winter.

For home potted osmanthus, you can use a mixture of fermented liquid fertilizer made from bean dregs, fish intestines, etc. and add water for use, but it must not be too concentrated. Osmanthus does not like heavy fertilizers, so it is sufficient to apply it once every half a month or so.

How to fertilize the sweet-scented osmanthus tree to make it grow faster

Dig trenches outside the crown projection of the osmanthus tree and apply fertilizer. The depth of the trench depends on the depth of the roots. The fertilizer cannot come into contact with the branches and leaves, nor can it directly come into contact with the thick roots and fibrous roots.

Do not apply fertilizer during the dormant period of osmanthus, because at this time the roots' demand for nutrients is very small and photosynthesis is very weak. If you apply fertilizer to it, root burn is likely to occur.

Points to note when fertilizing hanging flower trees

1. In late March of spring, apply 0.1-0.3 kg of quick-acting nitrogen fertilizer to each osmanthus plant to promote its growth and produce more shoots. In July, apply 0.1-0.3 kg of quick-acting phosphorus and potassium fertilizer to each plant. In October, apply 2-3 kg of organic fertilizer to each plant to prepare for wintering.

2. When caring for the osmanthus tree, if you accidentally apply too much fertilizer and cause root burn, you should immediately change the soil or water it plenty to dilute the fertilizer.

3. Osmanthus likes light, so after fertilizing, you must ensure sufficient scattered light. If you keep it at home, it is recommended to place it in a place with good lighting, such as a balcony or windowsill.
