A Complete Guide to Growing and Caring for Chinese Roses

The Chinese rose is a plant with strong adaptability and strong cold tolerance, and its requirements for growing soil are not very strict. Let me introduce it to you next.

How to Grow Chinese Roses

First, plant the seedling bed in a sunny, dry and well-ventilated place. If the growing-season cutting method is used for planting, it needs to be done in the first half of the year from April to May and in the second half from September to October, when the climate is neither too cold nor too hot and most suitable for cuttings. The cuttings are best taken in the morning when there is dew, choosing branches of the current year that are robust and well developed, free of pests and diseases, with yellow scales at the base that have not yet fallen off; the length is 8-14 cm, and short branches that have not flowered or have flowered are preferable; next, after the cuttings are prepared, insert them into the pot immediately, to a depth of 1/3 of the cutting, as too deep or too shallow is not good. At this stage, the pot should be placed in a shady place, away from direct sunlight, and in dry weather a sprayer should be used to mist the leaf surfaces several times; finally, after about 30 days, when the new leaves are found to have grown larger and turned green, they can be planted in pots.

Precautions for Growing Chinese Roses

Temperature Precautions for Growing Chinese Roses

In winter, Chinese roses overwinter indoors. Because the room temperature is relatively high, they cannot enter dormancy properly. By the following spring, before they are brought outdoors, the leaf buds have already begun to sprout and grow, consuming most of the nutrients stored in the branches. After being brought outdoors, the young buds cannot adapt to the changeable climate and cannot withstand the invasion of cold air and cold winds, which easily causes the plant to die.

Precautions for Repotting Chinese Roses

When repotting in spring, the plant has already begun to grow. If too much of the original potting soil is replaced, the root system will be damaged, which also easily causes the new buds to die after repotting, and may even cause the whole plant to die. Therefore, repotting should be done before the leaf buds sprout.

Precautions for Root Pruning of Chinese Roses

When repotting, if the plant's roots are pruned too severely, making it difficult for their absorption capacity to recover, the balance between the aboveground and underground parts is broken, and the plant will also die.

Propagation Methods for Growing Chinese Roses

Seed Propagation Method for Chinese Roses

Seed propagation is mostly used for propagating rootstock seedlings and breeding new varieties. Plants sown in spring can bloom in the autumn of the same year. Plants sown in winter need mats for cold protection during the cold winter. Harvest the fruit during the ripening period from October to November, dry them in the sun for a few days, then crush the flesh with a slightly light roller, wash the seeds out with water, and place them in sand for moist storage.

Cutting Propagation Method for Chinese Roses

Cutting is the main method of propagating Chinese roses. In the south, softwood cuttings can be done in spring and autumn. Spring cuttings are done from March to April, when the relative humidity is relatively high; they can take root 25 days after cutting, with a high survival rate. Autumn cuttings begin in late August and end at the end of October; at this time, the rooting period is extended by 10-15 days compared with spring cuttings.

Grafting Propagation Method for Chinese Roses

Grafting is also a commonly used method in production, especially for excellent varieties that are difficult to root from cuttings. The rootstock should be selected from types with strong adaptability and resistance to powdery mildew and brown spot, such as wild rose, Rosa multiflora var. cathayensis, and Rosa spinosissima. Branch grafting or bud grafting is mostly used.
