Rose growth environment conditions and characteristics

Rose growth environment conditions and requirements

Rose has a wide growing range and is commonly planted in both the north and south of my country. Rose prefers a cool and warm climate and is afraid of high temperatures. The most suitable temperature is 18℃~28℃. When the temperature exceeds 32℃, flower bud differentiation will be inhibited, which means that it will not bloom in midsummer.

Rose growth temperature

Roses bloom around May 1st, and the temperature is 20-30 degrees. If the temperature is lower, the flowering will be slow. If it is above 36 degrees, the leaves will be burned. When the temperature is below 5 degrees Celsius, it will completely enter a dormant period, and it will be frozen to death at 0 degrees.

Rose growth humidity

Roses are generally planted outdoors. During the production period, the air humidity should not be lower than 70-80%. It is most suitable to keep the humidity within this range. When the roses grow new branches and leaves, water them once every two days. When buds appear, water them once a day. During the flowering period, water them once in the morning.

Rose growing soil

Roses require soil with good drainage, slightly acidic, loose and fertile. Alkaline soil or clay soil cannot be used, otherwise it will affect the growth. During the cultivation period, five parts of garden soil, three parts of leaf mold and two parts of rice husk ash can be used to prepare the soil, which can basically meet the growth needs.

Rose growth cycle and process

Roses bloom most vigorously from April to September. The growth cycle of roses is as long as 200 days, starting from mid-May and lasting until mid-November every year, hence the name "Monthly Red". Generally, it takes 10 days from germination to bud growth of 5CM. It takes 15 days from 5CM growth to budding, and 25 days from budding to flowering.
