When the rose flower is in the growing season, that is, spring and autumn, it needs to be fertilized. This is better for it to grow branches and leaves. And before the rose blooms, that is, the budding stage, it also needs to be fertilized. This can promote it to grow more bracts and keep it blooming during the flowering period.
When it is in the growing season, it can be applied with some compound flower fertilizer containing more nitrogen elements. If not, you can also use bean cake or chicken manure. In this way, it can directly provide nutrition for the growth of its branches and leaves, and help it grow luxuriant. Before flowering, it can be sprayed with some diluted potassium dihydrogen phosphate. This can stimulate it to bloom.
In the growing season, fertilizer can be applied every 10 days or so. If the bean cake fertilizer is used, it can be diluted with water and then poured into the soil. If slow-release fertilizer is used, you can poke a hole directly at the edge of the flowerpot, put the fertilizer in it, and then bury the hole. At the flowering stage, potassium dihydrogen phosphate can be dissolved and diluted with water, and then it can be installed in a watering can and sprayed on the branches and leaves of the plant.
