First of all, we should know that when we sow roses, we need to sow one seed at a time, and the distance between each seed should be the best. Then, cover them with suitable soil and water, and let them germinate in a cool and ventilated place. In fact, roses, like most xerophytes, are particularly afraid of waterlogging. We must never water roses all day, because if you just plant a few in a flowerpot, it will bloom early.
It must be remembered that the soil in the flowerpot will not be watered until it is dry. Once watered, it should be thoroughly watered at one time, otherwise the root of the rose will be soaked in water, leading to the death of the rose. Secondly, we all know that the growth and development of plants need photosynthesis, so potted plants are irregularly placed on the balcony to get enough light. When your rose leaves turn yellow or rot, it means that your plants are not getting enough light.
After all the above steps are completed, you should also know that plants need fertilization, and the fertilizer needed by roses is not very strong, which will sting the roses to death. All it needs is light water fertilizer or a little nitrogen fertilizer contained in rice washing water. In fact, as long as the leaves and flowers of your rose are not morbid, you don't need chemical fertilizer.
If roses are planted in a large area in the garden or field, it is best to choose a place where there is plenty of sunshine and no water accumulation, and loosen the soil every spring. Usually, if you remove grass and insects from it, it will grow freely and healthily.
I'll stop here and introduce the technique of growing roses!
