How to breed thorn roses (matters needing attention in raising thorn roses)

If you want to raise Rosa roxburghii, you must first understand its characteristics. Rosa roxburghii is widely distributed in northern China, and its flowering period is in winter and spring, so it is relatively cold-resistant. But at the same time, Rosa roxburghii likes sunshine and warmth, and grows more vigorously under the conditions of abundant sunshine and high temperature. Rosa roxburghii is drought-tolerant, and the requirement for water content is not high, and the required soil should be easy to drain. The following is a detailed introduction to you from five aspects: soil, light, temperature, moisture and fertilizer.

I. Soil

The soil where Rosa davurica grows should be loose, rich in organic matter and well drained sand, which can be mixed with pastoral soil and sand to make the soil quickly filter water and prevent root rot caused by stagnant water.

Second, light.

Rosa roxburghii likes sunshine, and it needs enough sunshine to ensure nutrient accumulation during flowering. Under the condition of sufficient light, the flowering quality and quantity of Rosa roxburghii will be greatly improved.

Third, temperature.

Rosa roxburghii is widely distributed in the northern region and has the characteristics of cold tolerance, and it can safely overwinter at room temperature above 3℃ in winter. However, in order to make Rosa roxburghii blossom smoothly, the temperature must reach above 65438 05℃. If the temperature condition is maintained all the time, plus sufficient light, it will bloom all winter, so it is best to put Rosa roxburghii in an indoor culture with heating equipment in winter.

Fourth, moisture.

Rosa roxburghii is moisture-proof and drought-resistant, and does not need much water, as long as the soil is kept moist. It should be noted that when the humidity is too low, the leaves will dry up and fall off, enter a dormant state, and even wither and die when they are extremely short of water.

Verb (abbreviation for verb) fertilizer

Rosa roxburghii is strong and needs little fertilizer. In winter flowering period, only topdressing is needed once every half month. Fertilizer can be organic liquid fertilizer or compound fertilizer, and the best choice is decomposed organic fertilizer, which can make the stems of Rosa roxburghii strong and promote the flowering of Rosa roxburghii.
