Vermilion is an evergreen shrub that belongs to the wild peony family. It has beautiful red flowers and is a very popular potted ornamental plant. The red has a long flowering period that lasts from spring to autumn, giving people a long time to enjoy.
Cultivating vermilion not only beautifies the environment, but also has many other benefits:
Air Purification: Vermilion can absorb harmful substances in the air and release fresh oxygen, which helps to improve air quality.
Stress Reduction and Relaxation: Admiring the bright red flowers of the vermilion can make you feel good and reduce stress.
Courtyard landscape: Vermilion can be used as a potted plant or planted in the garden landscape to play a decorative role.
The most suitable temperature range for the growth of vermilion is between 15-25 degrees Celsius. The temperature should not be lower than 10 degrees Celsius in winter, and the high temperature should not exceed 35 degrees Celsius in summer. Proper air humidity is also important for the growth and flowering of vermilion, and the humidity should be maintained between 50%-70%.
Vermilion prefers a well-lit environment. You can choose a half-sunny and half-shady location to ensure 4-6 hours of sunlight per day. However, in the summer heat, you also need shade to avoid direct sunlight.
Vermilion red needs a good ventilation environment to grow. The planting site should avoid enclosed spaces and ensure air circulation. At the same time, vermilion is not resistant to cold, so it should be moved indoors or in a greenhouse for protection in winter.
Vermilion is not too strict on the soil, but loose and fertile soil with good aeration and drainage will be more conducive to its growth. You can choose to mix peat, humus and vermiculite to make culture soil.
Vermilion requires the right amount of nutrients to grow. It is recommended to apply a slow-release compound fertilizer once a month to ensure that the plants receive balanced nutrition. In spring and summer, the amount of nitrogen fertilizer can be appropriately increased to promote the growth of new branches.
Vermilion is not waterlogged, be careful not to overwater. When watering, it should be watered thoroughly and breathable, and the surface should be slightly dry before continuing to water. Frequent watering is required in the summer, and the amount of water can be reduced in the winter.
Vermilion can be appropriately applied to slow-release organic fertilizer or compound fertilizer in spring every year to supplement the base fertilizer. Foliar fertilizer can be sprayed once a month in summer to promote plant growth and flowering. Be careful not to over-fertilize so as not to burn the root system.
The main purposes of pruning vermilion are as follows:
Dredging branches and leaves, increasing ventilation and light transmission;
Adjust the shape of the plant to maintain the appearance of beauty;
Control the size of the plant and adapt to the size of the pot;
Remove long and dead branches to ensure plant health.
Vermilion can be pruned vigorously in late spring and early summer to encourage new shoots to germinate, but not too much. Light pruning maintenance can be carried out at any time. Prune with pruning scissors, pay attention to retaining the main trunk and properly thinning the middle and lower branches, so that the plants are well ventilated.
Common diseases of Vermilion are:
Leaf spot: brown spots appear on the leaves, which expand later and cause defoliation;
Rot disease: rot of the stem or root system and softening;
Powdery mildew: the appearance of powdery powder on the surface of leaves and shoots.
Common insect pests are:
Spider mites: sucking the sap causes the leaves to turn yellow and fall off;
Aphids: feed on young shoots and leaves, causing leaf deformation and wilting;
Scale insects: feed on plant sap, causing branches and leaves to lose their luster.
Keep the environment clean and hygienic, increase ventilation, and improve plant resistance;
Prune dead branches and fallen leaves in time to remove the source of pests and diseases;
Use special fungicides or insecticides for spraying control;
Collect the damaged plants and destroy them in time to prevent the spread.
Healthy semi-lignified shoots are used as cuttings that are easy to take root and germinate under moisturizing conditions. Proper application of hormone rooting powder can effectively improve the survival rate of cuttings.
The seeds of vermilion can be used for seedling raising. Mature and healthy seeds are collected, sown after proper treatment, and transplanted after germination and growth into small seedlings. However, this method requires a longer period and is therefore less used.
Grafting propagation can effectively transfer the characteristics of excellent varieties to new plants. Grafting the rootstock of the excellent variety of Vermilion to the cold-tolerant and disease-resistant wild base plant can obtain a new plant with both qualities. Grafting technology operations require specialized knowledge.
Breeding vermilion red flowering needs to pay attention to environmental details such as temperature and humidity, light, soil, watering and fertilization, and also need to pay attention to pruning and shaping, pest control and other care measures. In addition, through various propagation methods such as cuttings, sowing and grafting, more healthy flowering vermilion plants can also be cultivated. As long as you grasp the above points, you will be able to make the vermilion red bloom under your careful cultivation.
How much water should I water for vermilion?
Generally, watering every 10-14 days is appropriate, depending on the soil and environmental humidity. Water thoroughly and breathe, and wait for the surface to dry slightly before watering. In summer, you need to increase the frequency of watering.
Can Vermilion be grown in full sunlight?
Vermilion prefers semi-sunny and semi-dark light conditions, with 4-6 hours of sunlight every day. Full sunlight can easily cause leaf burns, which is not conducive to growth and flowering.
How long does it bloom?
Vermilion has a long flowering period that lasts from spring to autumn. Usually the best time to bloom is from March to May, after which new flowers continue to bloom.
What should I pay attention to when pruning vermilion?
When pruning, the main trunk should be retained, and the middle and lower branches and leaves should be appropriately thinned to increase light and air transmission. Be careful not to prune too much at one time, otherwise it will affect the growth of the plant.
When does Vermilion need to be fertilized?
Slow-release organic fertilizer or compound fertilizer can be applied as a base fertilizer in spring. Foliar fertilizer is sprayed monthly during the summer growing period to supplement nutrients. Be careful not to overdo it.
