1、 How to fertilize
When the Rhododendron sprouts, it can be sprayed with some foliar fertilizer. Fertilizing before flowers bloom can promote flower bud differentiation, but after there are flower buds, you only need to spray leaf fertilizer. But when the bud grows to a certain extent, don't continue fertilization. There is no need to apply fertilizer during the flowering period. You can wait for the flowers to wither before replenishing nutrients p>
2、 Is it watered
When fertilizing cuckoos, they can be watered, but the amount of watering should not be too large. Generally, the next morning after fertilizing it, water it with clean water. The purpose of this is to help dissolve the fertilizer and better absorb the roots of the plant. Fertilization should be carried out when the soil is dry, and the time can be in the evening, so as not to endanger the growth of plants p>
3、 Precautions
1. Fertilization amount: the Rhododendron should be fertilized with thin fertilizer and frequently. Generally, fertilization is not needed in 1-2 years, which is that there is enough base fertilizer in the soil. For 3-5 years, fertilize once every 15 days; For plants that have grown for more than 4 years, the amount of fertilizer applied each time is about 20g p>
2. Concentration: it is a plant that likes fertilizer, but it should also pay attention not to use concentrated fertilizer when applying fertilizer. In the growing season, fertilization is generally applied with thin cake fertilizer and water, or the fertilizer retted by ourselves. It is necessary to apply fertilizer once before winter, but do not apply base fertilizer when changing pots p>
