How to apply fertilizer to roses

In addition to applying sufficient base fertilizer, roses have extremely high requirements for fertility during the growth period. It is necessary to apply water-soluble quick-acting fertilizer in time to provide timely nutrients for the growth of the plants. Usually, top dressing is required three times a year.

The first time is during the budding period. At this time, the temperature rises and the underground roots begin to grow and develop. When the roots grow to the top, there is a great demand for fertilizer, so fertilization must be done in time. The second time is during the flowering period, and quick-acting fertilizer must be applied quickly. The third time is after flowering. The flowering period consumes more nutrients, so fertilization must be done according to the growth of the plant.
