Cultivation methods and precautions of yellow rose

How to cultivate yellow rose

Soil requirements

Rosa rugosa is not very demanding on soil when growing. It is relatively resistant to drought and barrenness, and can also grow in alkaline soil. However, because Rosa rugosa is not tolerant to waterlogging, the soil must have good drainage and be as loose and breathable as possible.

Water and fertilizer management

When planting Rosa rugosa, first apply some well-rotted compost as base fertilizer. After it takes root, generally no further fertilizer is needed. However, in order to make it luxuriant, top dressing can be applied once every other year after flowering.

After planting, the yellow rose should be watered thoroughly once, and then watered again after about 3 days, and it will survive. In daily management, watering should be done in time depending on the drought situation to avoid wilting or even death due to excessive drought and water shortage. Pay attention to drainage and waterlogging prevention during the rainy season, and irrigate with antifreeze water once before frost.

prune

Yellow rose needs to be pruned frequently.

After flowering, pruning is required to remove dead flowers and branches to reduce nutrient consumption.

Pruning is also required after leaf fall or before budding, removing old branches, dead branches, and dense and weak branches to ensure vigorous growth. 1-2 year old branches should be pruned as little as possible to avoid reducing the number of flowers.

Precautions for the cultivation of yellow rose

Reproduction method

When propagating, the yellow rose is mostly propagated by division, layering and cutting.

Rosa rugosa has a strong ability to tiller and is suitable for reproduction by division, because division can produce seedlings quickly and has a high survival rate, while maintaining the plant's double-petal characteristics.

Diseases

Rosa rugosa is easy to cultivate, requires little management, and has few diseases and pests. Generally, powdery mildew will occur during the growth process of Rosa rugosa, which is mainly manifested by lesions on both sides of the leaves, with a sparse white powdery mold layer, causing the leaves to twist and the young leaves to turn purple-brown and die.
