Should I fertilize the osmanthus when it is about to bloom? What fertilizer should I use to make it bloom more?

1. Fertilize the osmanthus when it is about to bloom

It consumes more nutrients when it blooms than usual, so it is necessary to fertilize it. Only when there are sufficient nutrients can there be more flowers and the flowering period can be extended. If no fertilizer is applied, it will affect normal flowering and the flowering period will naturally be shortened.

2. Selection of fertilizer

If you want it to bloom more, you need to choose the right fertilizer. Before flowering, more phosphorus and potassium fertilizers should be applied to promote root growth, so as to preserve and promote flowers. The number of flowers will also be greater and the flowering period can be extended. Stop applying nitrogen fertilizer, otherwise it will cause vigorous growth of branches and leaves, which will easily lead to excessive growth. This will affect flowering and the flowering period will end early. In addition, be sure to stop fertilizing during the flowering period. Just wait until the flowers have completely withered before refertilizing them. This will also help the plant survive the winter and improve resistance.

3. Fertilization method

In addition to choosing the right type of fertilizer, you must also ensure that the fertilization method is correct. When applying fertilizer, try to stay away from the root system, as applying too close may burn the roots. It is best to water the plant once after each fertilization, which can dilute the fertilizer and allow the osmanthus to absorb it faster. Note that you should use a small amount each time and do it in multiple times. Do not use too much at one time, otherwise it will cause fertilizer damage. It is recommended to apply fertilizer once every half a month before flowering, and apply thin fertilizer frequently.
