Rosa Hybridda likes warm, sunny, air circulation environments. The optimum temperature for most varieties is 15 ~ 26℃ in the daytime and 10 ~ 15℃ at night. When the temperature is below 5℃ in winter, Rosa Hybridda enters dormancy. Some varieties can withstand low temperatures of -15℃ and high temperatures of 35℃; When the summer temperature lasts above 30℃, Rosa Hybridda enters semi-dormancy, and the plants grow poorly. Although they can also be pregnant with buds, the flowers are small, the color is dim and dull, and the ornamental value is lost.
Rosa Hybridda is native to East Asia. It is mainly distributed in North China, Northwest China and Southwest China, Japan, Korea and other places, and is also widely planted in many other countries. Rosa Hybridda is sun-loving, drought and waterlogging resistant, and also can withstand cold, suitable for growing in the more fertile sandy soil.
Rosa Hybridda is a new flower, enchanting, meaning to be together is a promise.
Rosa hybrida is a colorant that is harmless to human body and a dye aid to synthesize colorant. When the white rose (or white rose) is approaching its flowering period, Rosa Hybridda begins to water the flowers with dye, so that the flowers are like water absorption, and the colorant is inhaled to achieve dyeing. According to Flower experts, there are very few blue roses that grow naturally in the world. The "Rosa Hybridda" on sale in the market is the product of artificial dyeing. The more formal "Rosa Hybridda" starts to dye the flowers in the growing period, the color is natural and not easy to fade.

Rosa hybrida has straight cutting, mainly used in the production of cutting method, generally selected in the spring. The cuttings are selected from short and strong annual semi-lignified branches without heading, and cut at the top 8 ~ 10 cm as cuttings. The cuttings should be close to the node of the stem, and the cuttings should be treated by applying callus anticorrosive film around the cuttings to protect the integrity of the phloem. The cuttings should be treated by soaking in 800 times of high lipid film solution (preventing wound rot and virus infection, restoring the physiological vitality of the plant and promoting germination, roting and seedling emergence).
Aphids and night moths can damage plants and their leaves.
The beetle, the small ground tiger can harm the plant root, can use poison bait to trap kill.
Rust usually occurs on the back and stem of Rosa Hybridda leaves. Spray targeted drugs and new high lipid membrane, greatly improve the effective component rate of pesticide.
