1、 What kind of fertilizer
It should apply fertilizer frequently during the management period, and select the appropriate fertilizer species, so that it can blossom and grow better. The specific fertilizer to be applied depends on the season or growth stage. Base fertilizer should be applied at the beginning of planting, just use rotten fertilizer, and topdressing once half a month later. Nitrogen, phosphorus and potassium fertilizer should be applied before flowering to promote flower bud differentiation. Organic fertilizer should also be applied after flowering to supplement nutrition. Winter fertilizer should be applied at the end of autumn and the beginning of winter. At this time, nitrogen, phosphorus and calcium fertilizer can be used to improve the cold resistance p>
2、 What if you fertilize too much
Although it is a fertilizer loving plant, it should not be over fertilized at one time, otherwise the root system is easy to rot and burn the plant in serious cases. Therefore, excessive fertilization must be treated as soon as possible. A large amount of water can be poured for flushing, so that the fertilizer will flow out along the water after dilution, so as to avoid fertilizer damage. However, if the situation is serious, it is best to replace the soil as soon as possible and replace it with new soil to avoid rotten roots p>
3、 Fertilization method
To fertilize the roses, it is recommended to bury the fertilizer in the soil and not directly sprinkle it on the surface. Buried in the soil can be diluted faster and the plants can absorb better, but be careful not to bury too close or too deep. Too close is easy to burn roots, too deep is easy to dig roots. The excavated ditch should be shallower as far as possible. After being buried, it should be watered and diluted appropriately, so that it will be absorbed by the plants soon p>
