Rose fertilization considerations

Roses like fertilizers, proper fertilizers can make roses bloom more beautifully, but fertilize when there is a degree. When planting the pot, do not mix fertilizer in the transplanted culture soil, but supplement the compost. It may be a large granular fertilizer (commercially available) in which oil residue and bone powder are mixed. About 20 centimeters of potted plants, about 3 places. Try to bury the fertilizer at a depth that is not buried as far as possible away from the plant. When replacing, remove the old fertilizer and put it in a different place than before.

When the rose is just planted, organic fertilizer should be added as the base fertilizer. Oil, bone powder or decomposed fertilizer can be used. The dosage is 1/4-1/5 of the soil. Later, every half month of topdressing once, when weeding can be combined with weeding, and slightly loose soil, will make the rose grow better. In the winter when roses are dormant, fertilizer is buried in the mud. 20-30 cm from the base of the rose, digging a 20-40 cm deep pit. It doesn't matter if the root is broken. After adding sufficient humus soil or compost, and thoroughly mixing with the soil, each rose is mixed with 500-700 g of fermented fertilizer with a ratio of nitrogen, phosphorus and calcium of about 1:3:1. Do not fix it in one place, but apply it evenly without missing. In this case, there is no need to specialize in topdressing. The fertilizer in summer is applied in half the amount of fertilizer in winter. Because the rose is in the growth stage, don't dig the deep pit like the one dug in winter, but sprinkle it on the surface of the soil and mix it with the surrounding soil. If you dig a deep pit, you may be able to damage the roots that absorb water and nutrients. Pay attention.
