Rose likes sunshine, but also tolerates semi-shade. It is relatively cold-tolerant and can survive the winter in the open field in most areas of northern China. The soil requirements are not strict, and it is resistant to drought and barrenness, but it will grow better when planted in deep, loose, fertile, moist and well-drained soil, and it can also grow normally on heavy clay soil. Intolerant of water and moisture, avoid accumulation of water. When planting new plants, apply decomposed organic fertilizer. In the first one or two years after frost planting, you can dig trenches and apply basal fertilizer once every year in late autumn to facilitate growth and flowering. It has strong tillering ability, is resistant to pruning and pollution. The flowering period is generally from April to September every year and blooms sequentially, which can last up to half a year. Due to global warming due to the greenhouse effect, roses in some places begin to bloom as early as April or even March.

Rose, also known as wild rose, is a small flower that climbs the fence and is a deciduous shrub native to my country.

Roses do not choose soil very much, but whether they are planted on the ground or in pots, they grow best in sandy loam that is rich in humus. Roses like moisture but are afraid of moisture and avoid waterlogging. Therefore, when caring for roses, from the time when the roses sprout to before they bloom, you can water them more appropriately, so that the soil is moist but not waterlogged. Do not water too much after flowering, and the soil should be moist. When it is dry or wet, attention should be paid to drainage and waterlogging prevention during the rainy season.

Methods for cultivating roses

1. Sunshine: Roses are light-loving flowers and trees that require sufficient sunlight. Sufficient sunlight should be maintained during the growth period.

2. Watering: Roses like moisture but are afraid of moisture and avoid waterlogging. From germination to before flowering, you can water more appropriately, so that the soil is moist but not waterlogged. Do not water after flowering. If too much, the soil will become dry and wet, and attention should be paid to drainage and waterlogging prevention during the rainy season.

3. Fertilization: Roses like fertilizer and tolerate barrenness. They can apply nitrogen-based liquid fertilizer once or twice in March to promote the growth of branches and leaves. Apply it twice in April and May. Use phosphorus and potassium as the main fertilizer three times to promote more flowering of the fertile buds. Apply a rejuvenating fertilizer after flowering, and then no need to fertilize again. The longer the plant grows, the more flowers it blooms, and the more nutrients it needs. Soil and fertilize once every winter are needed to keep the twigs and flower buds lush and the scenery beautiful. When cultivating potted flowers, more attention should be paid to pruning and shaping. Due to the large amount of flowers produced, cut flowers need to be fertilized 1 to 2 times a week during the flowering season. Attention should be paid to cultivating the mother branches for flower picking and cutting off flower buds on weak branches.

4. Insect pests: Roses can be infected with many diseases, most of which are caused by fungi. Before the onset of the disease, you can spray 200 times the same amount of Bordeaux mixture to prevent it. When the disease occurs, spray 15% fentanin wettable powder 1000 times. , or 70% thiophanate methyl wettable powder 1000 times liquid.
