How to apply fertilizer to sweet osmanthus

1. Apply more nitrogen fertilizer

In addition to applying sufficient base fertilizer during cultivation, osmanthus also needs to be given appropriate topdressing. When it sprouts in March, you can apply more fertilizer. In order to make its new shoots grow stronger, you should apply nitrogen fertilizer 1-2 times, which is also beneficial to the differentiation of flower buds.

2. Supplement phosphorus and potassium fertilizers

In mid-to-late May, the new shoots will top out and enter the nutrient accumulation period. Appropriate supplementation of phosphorus and potassium fertilizers is needed, and nitrogen fertilizers can also be used. If the soil is dry before fertilizing, loosen the soil appropriately and water the leaves after applying fertilizer. This is to help the osmanthus absorb nutrients better.

3. Quick-acting fertilizer

In late October, the temperature is still relatively high, and its root system is still growing. At this time, you can apply quick-acting fertilizer mainly composed of nitrogen, supplemented by phosphorus and potassium fertilizers. This will help it bloom in the second year.

IV. Precautions

When applying top dressing, do not apply concentrated fertilizer or too much fertilizer. It is best not to apply fertilizer when the temperature is high, as it can easily burn the roots. Do not use fertilizer that is not fully decomposed, as it will also harm the plants.
