How to grow roses in pots and what to pay attention to

Growth habits of roses in pots

Roses prefer places with plenty of sunlight and fertile soil and are generally planted in the ground, which is conducive to the growth of their root system and allows them to grow more luxuriantly. Their roots are relatively cold-resistant and can withstand temperatures as low as minus 20°C.

Light requirements: Roses are light-loving plants with strict requirements for light. Indoor potted plants need to be guaranteed to receive sufficient light every day. During the growing season, the light must not be less than 8 hours a day. If the light is insufficient, it will cause excessive growth without flowering. Too much direct sunlight is also not good for the growth and development of roses, and can easily cause sunburn on the leaves.

During the budding period, compound fertilizer should be applied to promote rapid growth of plant branches and leaves. During the flowering period, quick-acting fertilizer should be applied to promote yield and improve the quality of flowers.

Potted rose pruning: Potted roses need to be pruned in spring. Weak branches, duplicate branches and diseased branches can be cut off to promote the growth of new branches. The withered flowers need to be pruned after the flowering period, otherwise they will not only be unsightly, but will also continue to consume nutrients and be detrimental to the germination of new buds. Excess side buds should also be cut off, leaving only one.

They need to be pruned in time during the growth period, and the withered flowers need to be cut off after flowering. This can reduce the loss of nutrients and enhance the ornamental value of the plant.
