How to Care for Roses to Keep Them Alive
This article introduces how to care for roses to keep them alive and the correct methods of rose cultivation. Below, the editor provides a detailed explanation.
Rose care management requires special attention to adequate sunlight, watering, fertilizing, pruning, and pest and disease control. Roses are adaptable to cold, drought, and various soil types. They belong to the Rosaceae family, Rosales genus, and are commonly known as roses, red roses, and Chinese roses. The horticultural varieties include purple double roses and purple twig roses. Roses are distributed in North China, Bulgaria, the United States, and other places, blooming from May to June with a fragrant scent. Below is an introduction to the care methods for roses.
1. Sunlight Requirements
Roses enjoy plenty of sunlight and require an adequate amount of direct light, with a minimum of 6 hours of direct sunlight.
2. Soil Requirements
Roses prefer neutral or slightly alkaline soil but can also be grown in slightly acidic soil. They don't have high fertility requirements and grow well in loose, well-draining soil with some humus.
3. Water Requirements
Roses are drought-tolerant but not flood-tolerant. Watering should be done when the soil is dry. No watering should be done when the temperature is below 0°C. For potted roses moved indoors for winter care, watering should be done at noon.
4. Temperature Requirements
The optimal growing temperature for roses is between 12 and 28°C. Roses can form flower buds in temperatures above 7°C, and the longer the high temperatures after bud formation, the earlier the flowers will bloom. It is not suitable to care for roses in a hot environment during the flowering period. When the temperature exceeds 35°C in summer, the plants will enter a dormant state, and appropriate measures should be taken to cool them.
Roses are relatively cold-tolerant, with most varieties able to withstand temperatures as low as -15°C. When winter temperatures are too low, the plants will enter a dormant period. In northern regions, no measures are needed for outdoor cultivation, but potted roses should be placed in a sunny environment at 20°C for wintering.
5. Fertilizing Methods
Spring and early summer are the blooming seasons for roses. Frequent fertilizing is necessary, with applications every 15 to 20 days. If a water-soluble solid fertilizer is used, it should be watered thoroughly after application.
6. Pruning Methods
Appropriate pruning should be done after the flowering period. If there is no need to bear fruit or keep seeds, withered flowers can be cut off. During the summer dormant period, pruning can be done for shaping and to prevent excessive growth.
7. Pest and Disease Control
Common pests and diseases of roses include rust, leaf spot, stem blight, aphids, red spiders, and longicorn beetles. Prompt control measures should be taken, and for diseases caused by pathogens, preventive measures such as spraying fungicides should be taken in advance.
