Most roses are world-famous ornamental plants, widely distributed across the cold-temperate to subtropical regions of Asia, Europe, North Africa and North America. In China they represent love, and many ancient civilizations around the world also regard the rose flower as a symbol of truth, goodness and beauty, with China rose and rose as their representative plants

When do roses bloom?

The flowering period of roses is generally from May to September each year, opening in sequence and lasting up to half a year. But in recent years, global warming caused by the greenhouse effect has made roses in some places start blooming as early as April, or even March. Therefore, flower lovers who want to enjoy the blooms should grasp the timing well so as not to miss the viewing period.

Reasons why roses do not bloom

1. Insufficient light, flower buds cannot differentiate. Roses are strongly sun-loving flowers, preferring moist soil that does not waterlog, and growing well under high temperature and high light conditions.

2. The plant is too small, or heavy watering causes the branches to grow excessively. Excessive growth makes all the nutrients go to the growth of branches and leaves, leaving no capacity to supply the needs of flowering. Controlling watering and thinning the branches and leaves to increase ventilation and light penetration between them can make roses bloom abundantly.

Cultivation and management of roses

1. Fertilization management: Roses like fertilizer and also tolerate poor soil. In March, apply 1 to 2 times a nitrogen-based liquid fertilizer to promote the growth of branches and leaves; in April to May, apply 2 to 3 times a phosphorus- and potassium-based fertilizer to encourage more buds and more flowers; after flowering, apply one rejuvenating fertilizer and then no more. Roses are sun-loving flowers, fond of warmth and also tolerant of cold; in North China and areas to its south, they can overwinter safely outdoors.

2. Watering management: Roses like moisture but fear wetness and are averse to waterlogging. From budding to before flowering, water a little more as appropriate, to the degree that the soil is moist but not waterlogged; after flowering, do not water too much, and let the soil dry and wet alternately; in the rainy season, pay attention to drainage to prevent waterlogging.

3. Pruning and trimming: Roses have strong sprouting ability and grow luxuriantly. If not pruned in time, under conditions of muggy heat, humidity, insufficient light and poor ventilation, they are prone to pests and diseases, so pruning should be carried out once after flowering. When pruning, you can select vigorous half-lignified branches of the current year for cuttings, placed in a semi-shaded spot; after they survive, transplant and set them out the following spring. You can also, before budding in early spring, cut off the rooted suckers from the base and plant them separately.

Reasons why roses do not bloom

Speaking of roses, some flower growers may be on the verge of tears, because the roses they planted for a whole year have never bloomed, which is very frustrating. What exactly causes roses not to bloom?

Roses are different from China roses; although both belong to the Rosaceae family, their flowering periods differ. Roses generally bloom in April (around Qingming), in cold places in May to June, and in some places they can also bloom in summer. Having learned about the flowering period of roses, let's now talk about the reasons why roses do not bloom:

First, some rose varieties have poor flowering ability, not like China roses, so flower growers need to be patient.

Second, make sure that what you are growing is a good variety of rose. The author has more than once seen flower growers who bought "roses" from Suqian shops; mentioning a certain place, flower growers have nothing but tales of blood and tears. The pictures are dazzling, but what is received is actually wild rose. Some flower growers are lucky enough to see it bloom, as in the picture below:

In addition, according to investigations, many roses bought by flower growers from Suqian shops are not easy to bloom; the reason is unknown, the secret behind the JS, for once they bloom, the game is up.

Third, light is an important condition for roses to bloom. If there is insufficient light, it will hinder roses from blooming.
