Fertilize the rose mainly when it is growing very vigorously, especially when it is flowering, that is, in May and June.In addition, if the nutrients in the soil are insufficient when planting or repotting, base fertilizer can also be used appropriately.
The fertilizer used in the growth period is mainly some liquid fertilizer, which can be purchased directly, and the effect is better.When planting or repotting, solid fertilizer is mainly used.
1. The liquid fertilizer used in the growth stage cannot be used directly, but needs to be diluted with water first, and then sprinkled on the soil surface.During the flowering period, special attention should be paid to liquid fertilizers containing phosphorus.The application of solid fertilizer is not so troublesome, it can be mixed in after the soil is prepared, just pay attention to mixing evenly.
2. The other is the frequency of fertilization.In the seedling stage, the amount of fertilizer needed is relatively not so much, which can be controlled to fertilize once in about 20 days.If the plant has grown up, then the amount of fertilizer needed will be slightly more, and it is better to control it once every 15 days or so.
When roses are dormant, they can be fertilized temporarily because their growth is basically stagnant.
