UK National Flower Rose: Blooming Period, Best Planting Time, and Greenhouse Planting Profit

The rose originated in China and has a long history of cultivation. It is the national flower of the United Kingdom. Its flower language: love, love and beauty, radiant glow, bravery, nobility. So when does the rose bloom? When is the best time to plant it? What is the profit from greenhouse planting? The specifics are compiled for you as follows:

Roses bloom in early May, and small-flowered varieties bloom between June and July. Once the flowers are fully open, the fragrance is lost and the petals fall off very easily, so flowers should be picked when the blooms have just opened, the petals are still folded and not yet spread, and the stamens have not yet emerged; the specific time is before sunrise. Practice has proven that the more roses are picked, the more times they bloom. If they are not picked, they can only bloom 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 far from walls to prevent sunlight reflection from scorching the flower buds and affecting blooming.

The growth habits of roses have been recorded in past dynasties' materia medica and modern traditional Chinese medicine monographs. Roses are heliophilous plants; with sufficient sunlight, the flower color is deeper and the fragrance is stronger. If sunlight is less than 8 hours during the growing season, they will grow leggy and not bloom.

When is the best time to plant roses?

From November to December after leaf fall, or in early March to April when the buds have just begun to sprout, divide the plants,

Each clump should have 2-3 branches and must have fibrous roots. Dip them in mud slurry for division and planting, and cut the stems back to 25-35 cm above the soil surface to encourage new shoots.

You can also in May-June press branches close to the ground into the soil, wound the buried part, and after 2-3 months they will take root, and can then be separated from the mother plant and planted elsewhere.

Before planting, apply decomposed organic fertilizer as a base fertilizer, and after planting water thoroughly. Roses like fertilizer; apply 4 times a year (early spring to promote budding, May to promote flowering, fertilizer supplement during the flowering period, and at the start of winter). Roses are afraid of waterlogging, so do not water too much. Frequent pruning can make the plants grow vigorously and produce abundant, colorful flowers. Pay attention to disease prevention.

For cuttings, autumn is better; for direct planting, of course spring is better.

Growing roses in greenhouses yields an annual income of 25,000 yuan

According to market surveys, in the fresh flower market, roses are the flower variety with the largest sales volume. A small flower shop of just over ten to twenty square meters can sell 200,000 rose stems in a year. For greenhouse rose cultivation, 4,500 rose plants can be planted 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 one crop comes out in October of the second half of the year or later. Some greenhouses also produce one crop before Valentine's Day, so some greenhouse roses produce three crops a year, and 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, and lower-quality ones sold for 15-20 yuan per bunch; on average, about 10 yuan per bunch. With three crops a year, the income can reach 24,000 yuan. After deducting expenses for greenhouses, fertilizer, pesticides, flower sleeves, and labor, the net income from growing one mu of roses is more than 10,000 yuan.

Planting prospects: plans to expand the area

After growing roses for so many years, Zhu Qunce found that the worst market was 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 terribly. After that, with the treatment of Dianchi Lake, rose cultivation around Kunming was no longer developed blindly, and the planting area no longer expanded substantially. In recent years, market prices have risen year by year.

At present, domestic rose pricing all references Kunming's prices. Growing locally not only guarantees freshness but also saves 3-4 yuan per bunch in transportation costs. As more and more newlyweds use fresh flowers instead of silk flowers at weddings, in recent years the fresh flower market has been expanding year by year. 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.
