1. How to plant potted roses

1. Preparation of pot soil. ① Mix 70% garbage soil and 30% river sand. ② Mix 60% dry river mud and 40% honeycomb cinder. ③ Mix 70% vegetable garden soil, 20% honeycomb cinder, and 10% river sand.

2. Potting time. It should be done after the leaves fall in early winter or before budding in early spring.

3. Fertilization and watering. Potted roses are restricted by limited pot soil, so they have strict requirements on fertilizer and water. ① Compound fertilizer is generally preferred as it is both convenient and hygienic. Because compound fertilizer contains various elements, nitrogen, phosphorus and potassium have a better mix. Apply about 20 grams per plant each time (the amount should not be too much). Use iron to cover the edges of the pot around the pot. Dig the soil to a depth of about 10 centimeters, then apply fertilizer and cover with soil. ② Watering is one of the basic tasks of growing flowers, but it is often the reason why plants die easily. Watering depends on the potting soil. Once it is dry, water it thoroughly. Too wet may cause root rot. The soil in the pot should be changed every other year. When changing the pot, the surrounding roots at the bottom of the pot should be cut off, so that the flowers can be more, larger and more colorful.

4. Plastic pruning

Generally, no pruning is required. Old plants can be pruned to remove dense branches, withered branches, and diseased and insect-infested branches. Roses bloom, pick them as they bloom and fall, and bloom again after picking, otherwise they will only bloom once.

5. Flowering period control

Generally, the natural flowering period is better.

Select a flat land with deep soil, loose layout and good drainage to create a rose garden. Dig pits with a plant spacing of 50 cm and a row spacing of 150-200 cm. The pit depth is 50 cm. Apply 10 kg of farmhouse to each pit. Fertilizer or bio-organic fertilizer.

To choose a good seedling, choose a strong rose seedling. The germinated seedling should have 2-3 branches; the grafted seedling requires a well-developed root system, a stem thickness of 3-4 mm, and a plant height of 30 cm. Plant as soon as possible, and seedlings shipped to other places must be dipped in pulp and packaged.

According to the requirements, about 700 rose seedlings per acre are needed for reasonable and dense planting. Since there are few seedlings that year, in order to save land, 1,500-2,000 rose seedlings can be planted per acre. In the second year, the seedlings can be transplanted or sold. , spring planting is held in early spring before the roses sprout; autumn planting is held from October to December, and summer planting is held on rainy days during the rainy season.

Scientific management of cultivating and weeding. Because the seedlings are small, weeds can easily grow. Weeding must be done promptly so that the seedlings are not damaged and there is no weed. Keep the soil loose. Fertilization is mainly based on organic fertilizers, and topdressing is usually done four times a year. The first time around Qingming Festival is to pour livestock manure water, which is called germination fertilizer, and water it in time. The second time in late April is before budding or flower picking. Manure and water are used to promote more and full flower buds; bio-organic fertilizer is applied in May, and overwintering fertilizer is applied in late autumn and early winter to ensure that the seedlings survive the winter safely. Prune off old branches, diseased branches, and weak branches after flowering in June and during the winter dormancy period to allow new branches to grow. Pay attention to the prevention and control of pests and diseases at all stages of field management.

6. Pest and disease control

The main pests of potted roses are caterpillars and scale insects. Caterpillars are easy to control. Once the scale insects attack, they are difficult to control and will cause the entire plant to be infected. And cause diseases, so the control of scale insects is the focus of domestic roses. To prevent and control scale insects, place roses in a well-ventilated and well-lit area, cut off branches with many roses, and retain a few main branches to allow internal ventilation. Keep the potting soil moist but not waterlogged. When white spots are found on rose branches, scrape them off with bamboo chips in time. If it is serious, cut off the entire branch or even all the branches, and spray scale insecticides together. Roses are not afraid of pruning, and we will also introduce the pruning of roses below. If you want roses to grow well and bloom more, pruning is very important. Generally, when overwintering, all branches should be cut off about 10 centimeters above the ground to ensure smooth overwintering. After spring, new shoots sprout. Select 2-3 new shoots and break off the rest with your hands. When the new shoots grow to about 10-15 cm, pick off the tops with your hands. After a few days, each branch will grow again. Produce 2-3 new buds, so that the entire rose plant will be complete and compact. Water and fertilizer can be concentrated on a few branches, and the flowers will be as large as you wish. After blooming, you can cut off the flower branches that have bloomed, and new flower branches will grow soon. If you want bigger flowers, keep fewer flower branches and remove some excess flower buds. If you want more flowers, top them more often. Roses consume a lot of nutrients when blooming, so they must be fertilized in time before budding and after blooming.

2. Maintenance of roses

1. Wrap them with plastic film. After selecting satisfactory flowers, be sure to wrap them in bunches with plastic film to avoid water loss and return. Cut it as soon as possible and insert it in the water to extend the viewing period.

2. Fill the glass vase with about two-thirds of water, add a little salt, and cut off about one centimeter of the lower part of each flower stem. , it is best to make a horseshoe-shaped cut, that is, an oblique cut, so that it can last for about a week

3. Soak the flower roots in hot water for 15 seconds, and then subtract the soaked part.

Just insert it into the vase and it can be maintained for a week

4. Add 5% sugar and 50PPM silver nitrate per liter of water in the bottle to make a vase insertion solution.

5. Packed into bundles Roses generally contain water in their packaging, just pour a bowl of water every day.
