When Do English Roses Bloom? Planting Time and Greenhouse Profit Explained
Roses originated in China, have a long history of cultivation, and are the national flower of England. Their flower language: love, love and beauty, radiant glow, bravery, nobility. So when do roses bloom? When is the best time to plant them? What are the profits of greenhouse cultivation? Here is a detailed summary below:
Roses bloom in early May, and small-flowered varieties bloom between June and July. Once the flowers are fully open, the fragrance dissipates and the petals drop very easily, so flowers should be picked when they have just begun to open, while the petals are still folded and not yet spread and the stamens have not yet emerged; the specific time is before sunrise. Practice has shown that the more roses are picked, the more times they bloom. If they are not picked, they can bloom only once a year.
Roses like plenty of sunlight, tolerate cold and drought, and prefer well-drained, loose, fertile loam or light loam. They grow poorly in clay loam and bloom poorly. They should be planted in a well-ventilated place away from walls to prevent sunlight reflection from scorching the buds and affecting blooming.
The growth habits of roses have been recorded in materia medica of past dynasties and in modern traditional Chinese medicine monographs. Roses are sun-loving plants; with sufficient sunlight, the flower color is deeper and the fragrance is stronger. If sunlight during the growing season is less than 8 hours, they grow leggy and do not bloom.
The Best Time to Plant Roses
Divide plants in November-December after leaf fall or in March-early April when buds have just begun to sprout,
Each clump should carry 2-3 branches and must include fibrous roots. Dip them in mud slurry for planting, and cut the stems back to 25-35 cm above the soil surface to encourage new branch growth.
Alternatively, in May-June, press branches near the ground into the soil, wound the buried portion, and after 2-3 months they will root and can be separated from the mother plant and planted elsewhere.
Before planting, apply decomposed organic fertilizer as a base fertilizer, and water thoroughly after planting. Roses like fertilizer; apply it 4 times a year (early spring to promote budding, May to promote flowering, during the flowering period as a supplementary fertilizer, and at the onset of winter). Roses are afraid of waterlogging, so do not water too much. Regular pruning can keep the plants growing vigorously with abundant and colorful flowers. Pay attention to disease prevention.
For cuttings, autumn is better; for direct planting, of course spring is better.
Greenhouse Rose Growing Brings Annual Income of 25,000 yuan
According to market surveys, roses are the flower variety with the largest sales volume in the fresh flower market. A small flower shop of just over ten or twenty sq m sells as many as 200,000 rose stems a year. For greenhouse rose cultivation, 4,500 rose plants can be grown per mu. It can produce 4 to 5 crops a year, with an annual output of 70,000 to 80,000 stems, and a net income of about 25,000 yuan.
Greenhouse Roses Produce at Least Three Crops a Year
Zhu Qunce's rose garden mainly has 10 varieties including Carola and Yanfen. Generally, before May 1, one crop of naturally grown roses is cut, another crop is cut in June, and then production is controlled until October of the second half of the year or later for one more crop. Some greenhouses also produce one crop before Valentine's Day, so some greenhouse roses produce three crops a year, while some greenhouses cut four crops.
Zhu Qunce said that one mu generally produces 800 bunches per crop. In the first half of the year, the price per bunch may be less than 10 yuan, but in the second half of the year the price is generally above 10 yuan. In the second half of last year, Carola sold for as much as 50 yuan per bunch at its most expensive, while lower-quality ones sold for 15-20 yuan per bunch. On average, about 10 yuan per bunch, the income from three crops a year can reach 24,000 yuan. After deducting costs for greenhouses, fertilizer, pesticides, flower sleeves, labor, and so on, the net income from growing one mu of roses is more than 10,000 yuan.
Planting Prospects and Plans to Expand the Area
After so many years of growing roses, Zhu Qunce found that the worst market was in 2005. That year, Kunming roses sold for as little as 5 jiao per bunch, while the wrapping paper for a bunch cost 4 jiao per sheet. Many growers lost heavily. After that, with the treatment of Dianchi Lake, rose cultivation around Kunming was no longer developed blindly, and the planting area no longer expanded significantly. In recent years, market prices have risen year by year.
At present, domestic rose pricing all refers to Kunming prices. Growing them locally not only guarantees freshness but can also save 3 to 4 yuan per bunch in transportation costs. As many newlyweds increasingly use fresh flowers instead of silk flowers at weddings, the fresh flower market has been expanding year by year in recent years. Although Zhu Qunce's rose planting area has expanded year by year, he has no worries about sales, and sometimes supply even falls short of demand.
