Introduction to the planting methods and techniques of Rose

Rose is a very beautiful flower, because its different colors imply different, so it is a popular variety in flower shops. Rose for planting environment requirements are not very high, common planting methods are open field planting and potted planting, the following together to see the technical points.

1. Key points of rose planting technology in open field

1. Land selection and preparation

Choose well-ventilated, sunny, dry terrain plot planting. It is not advisable to choose low-lying plots. The land is usually ploughed before winter, organic manure applied, leveled and harrowed for seed.

2. Breeding methods

Rose propagation methods are usually used in the production of asexual propagation: plant division, layering, grafting and cuttage, which is more used in plant division propagation. Spring, autumn and rainy season, preferably during dormancy.

3. Field management

Roses are cultivated in the open field. Although it has strong adaptability to the environment and can be managed extensively, in order to improve yield and quality, it still needs to strengthen field management. When planting, decomposed organic fertilizer should be applied. Because roses are fertile plants, fertilizer should be applied four times a year in general: one time before germination in early spring, one time before flowering (about May), one time before flowering, one time before flowering, and one time before wintering.

Early spring drought should be watered in time to promote flower bud differentiation and prolong flowering time. Intertill and weed frequently during the growth period. Rose afraid of waterlogging, if the ponding time is a little longer, the lower leaves will be yellow, serious plant death, so the rainy season to timely drainage. After winter, the rose garden will be generally turned over, combined with fertilization and soil cultivation. Those with sparse branches should cultivate more soil to promote branch germination, otherwise less soil.

4. Shaping and pruning

Reshaping and pruning are important links in rose management. Because roses bloom on the branches of the same year, frequent pruning can make the plants grow vigorously, the tree shape is correct, and the flowering life of the plants can be extended. Pruning at flowering and dormancy.

II. Key points of potted rose planting technology

1. Potting soil

Potted roses in terms of soil requirements fertile soil, loose, good drainage, can use garbage soil and river sand, and according to the ratio of 7:3 for mixing, mix well use; also use dry river mud and burned honeycomb cinder, and according to the ratio of 6:4 for mixing, mix well use; not only this, there is a method, can use vegetable garden soil, burned honeycomb cinder, river sand, and according to the ratio of 7:2:1 for mixing, mix well use.

2. Temperature and Light

Rose likes warm and sunny growth environment, relatively cold-resistant, suitable for growth in a warm environment of about 15~25 degrees; roses belong to positive plants, sunshine duration of not less than 6 hours a day is good, full sunshine will make the color gorgeous, fragrance more rich, insufficient light will appear excessive growth and no flowering phenomenon. Therefore, the family potted roses should be placed in the south balcony, sunny south windowsill and other places with sufficient sunlight for maintenance.

3. Fertilization

In the maintenance, we need to fertilize the potted roses. The potted roses also have certain requirements for fertilizer and water. Fertilization should choose compound fertilizer with excellent efficacy, so as to meet the needs of nitrogen, phosphorus, potassium and other nutrients when the roses grow. Fertilization should be carried out along the edge of the flowerpot, buried with fertilizer, and then watered. Rose seedlings on water requirements are not too high, we see the pot soil dry after watering enough water, can not let the pot soil too wet, otherwise it will make the leaves of rose seedlings yellow.

4, pruning

How to prune roses? The flowering period of roses is around May ~ August every year. After the roses wither at the end of August and before the winter dormancy period arrives, the aging branches, pest branches and relatively weak branches of roses should be thoroughly pruned. Each plant should leave 4 to 5 branches. These branches need to be 40 cm to 50 cm away from the ground. Each branch should leave one or two lateral branches. Two short buds should be left on the lateral branches to facilitate the concentration of nutrients. Accumulate enough energy for the vigorous growth and flowering of new year roses.
