Detailed Explanation of Rose Planting Methods and Techniques

The rose is a very beautiful flowering plant, and because different colors carry different meanings, it is a relatively popular variety in flower shops. Roses do not have very high requirements for the growing environment, and the common planting methods include open-field planting and potted planting. Let's take a look at the technical points below.

I. Key Technical Points for Open-Field Rose Planting

1. Site Selection and Land Preparation

Choose a plot with good ventilation, sufficient sunlight, and relatively high, dry terrain for planting. Low-lying plots should not be chosen. Usually, the land is plowed and turned before winter, organic fertilizer is applied, and the soil is leveled and raked fine ready for planting.

2. Propagation Methods

In production, rose propagation usually uses asexual methods: division, layering, grafting, and cuttings, among which division is more widely used. The time is spring, autumn, and the rainy season, and it is better to carry it out during the dormant period.

3. Field Management

Roses are mostly cultivated in the open field. Although they have strong adaptability to the environment and can be managed somewhat extensively, field management still needs to be strengthened to increase yield and quality. When planting, decomposed organic fertilizer should be applied. Because roses are fertilizer-loving plants, under normal circumstances they need to be fertilized 4 times a year: apply 1 round of sprouting fertilizer before budding in early spring, then apply 1 round of flower-promoting fertilizer before flowering (about May), apply 1 more round of flower-promoting fertilizer during the flowering period, and apply 1 round of wintering fertilizer before overwintering.

In early spring, when the weather is dry, water promptly to promote flower bud differentiation and extend the flowering time. During the growth period, cultivation and weeding should be carried out frequently. Roses are afraid of waterlogging; if water accumulates for even a slightly long time, the lower leaves will turn yellow and fall, and in severe cases the plant will die, so drainage should be done promptly during the rainy season. After winter begins, turn over the rose garden generally, combining fertilization with earthing up. For those with sparse branches, earth up more to promote branch sprouting; conversely, earth up less.

4. Shaping and Pruning

Shaping and pruning are important parts of rose management work. Because roses bloom on the current year's branches, frequent pruning can make the plants grow vigorously, keep the tree shape neat, and extend the number of years the plant blooms. Pruning is divided into pruning during the flowering period and pruning during the dormant period.

II. Key Technical Points for Potted Rose Planting

1. Potted Soil

Potted roses require fertile, loose soil with good drainage. You can use garbage soil and river sand mixed in a 7:3 ratio, stir well, and use; you can also use dry river mud and burned honeycomb coal cinders mixed in a 6:4 ratio, stir well, and use; not only that, there is another method: you can use garden soil, burned honeycomb coal cinders, and river sand mixed in a 7:2:1 ratio, stir well, and use.

2. Temperature and Light

Roses like a warm growing environment with sufficient light and are relatively cold-tolerant. They are suitable for growing in a warm environment of about 15-25 degrees; roses are sun-loving plants, and it is best if the daily sunshine duration is not less than 6 hours. Sufficient sunshine will make the flower colors more brilliant and the fragrance more intense, while insufficient light will cause excessive vegetative growth without flowering. Therefore, for household potted roses, place them in a south balcony, a sunny south windowsill, or other places with sufficient sunlight for care.

3. Fertilization

During care, we need to fertilize potted roses. Potted rose seedlings also have certain requirements for fertilizer and water. For fertilization, choose a compound fertilizer with relatively excellent effects, so that it can meet the needs of rose seedlings for various nutrients such as nitrogen, phosphorus, and potassium during growth. When fertilizing, dig deeply along the edge of the flower pot, bury the fertilizer, and then water. Rose seedlings do not have very high water requirements. After you see the potting soil become dry, water thoroughly, but do not let the potting soil become too wet, otherwise the leaves of the rose seedlings will turn yellow.

4. Pruning

How to prune roses: the flowering period of roses is around May to August each year. When the roses finish blooming at the end of August and before the winter dormant period arrives, carry out a thorough pruning of the rose's aged branches, pest- and disease-affected branches, and relatively weak branches. Keep 4 to 5 branches per plant, and these branches need to be 40 cm to 50 cm from the ground. Keep one to two side branches on each, and keep two short buds on the side branches, so as to help concentrate nutrients and accumulate enough energy for the vigorous growth and flowering of the roses the following year.
