Give When fertilizing roses, it is recommended to bury the fertilizer in the soil and do not spread it directly on the surface. Burying it in the soil can dilute it faster and the plants can absorb it better, but be careful not to bury it too close or too deep. Too close and easy to burn the roots, too deep to dig into the root system. The trench dug should be as shallow as possible. After burying it, water it appropriately to dilute it, so that it will be quickly absorbed by the plant.
