Life habits of roses:

Rose is a shallow-rooted plant with strong germination ability, sunshine-loving, cold and drought tolerance and strong adaptability. However, in a cool and ventilated place, the growth is poor and the flowers are sparse, which leads to plant elongation. Roses are best grown in deep, fertile, well-drained neutral or slightly acidic light loam and slightly alkaline soil.

Roses are afraid of waterlogging, which lasts a little longer, and the lower parts of branches and leaves are prone to yellowing. Severe waterlogging will lead to the death of the whole plant. Don't plant roses too close to the wall to avoid sunburn caused by sunlight reflection. Rose is a temperate tree species, which is cold-resistant and drought-tolerant. The requirements for soil are not strict. It can grow on weak alkaline soil.

It grows and blooms best in neutral or slightly acidic light loam rich in humus and well drained. It likes sunshine best. Poor shade growth potential, sparse flowering period, water intolerance, yellow lower leaves, good tillering when exposed to water. Strong and growing rapidly.
