After roses show buds, it is necessary to increase the application of phosphorus and potassium fertilizers.

You can use a 0.2% potassium dihydrogen phosphate solution to water the roots, which can promote flowering.
During this period, it is important to apply thin and frequent fertilization, not too much or too concentrated, to avoid fertilizer damage and the problem of falling flowers and buds. It is also not advisable to apply too much nitrogen fertilizer, as excessive growth of branches and leaves may affect the growth of flower buds. Once the flowers have bloomed, fertilization should be stopped, otherwise the flowering period will be shortened.

After rose buds appear, watering should follow the method of 'watering when dry and watering thoroughly'. Do not let the soil become too dry, or the flower buds will dry out. Generally, if you insert your finger into the soil and find it dry without moisture, you can water the flowers. Of course, it should not be too wet or waterlogged, as this may hinder the roots' respiration, leading to root rot and even the death of the rose.
