How to grow weigela? Detailed explanation of cultivation methods and precautions
Soil
Weigela has extremely strong adaptability and is very easy to cultivate, growing rapidly. Generally, it is better to choose well-drained sandy soil as the cultivation soil. There are also many propagation methods, generally sowing, cuttings, and layering. Taking sowing as an example, it needs to be done in windless weather.
Fertilizing
Before flowering in early spring, apply decomposed compost once, and it will bloom abundantly year after year. Compost is an organic fertilizer made from animal and plant remains and excrement containing waste materials, decomposed by microorganisms under certain conditions. During the growing season, fertilize once or twice a month.
Watering
Pay attention to watering weigela during the growing season. After spring arrives, gradually increase the amount of watering. Keep the soil moist. Summer is a high-temperature season, so ensure sufficient moisture and pay attention to cooling. If necessary, move it to a shaded place. During the planting period, water thoroughly at least twice a month to meet the growth needs of weigela.
Pest and disease control
It has strong cold resistance and likes deep, moist soil rich in humus, but it is afraid of waterlogging, so it needs to be planted in a sunny spot. This flower does not have many pests and diseases. Occasionally there are aphids and red spider mites, which can be killed by spraying dimethoate.
Now that you know the cultivation methods of weigela, many flower lovers may also want to learn about the value of weigela, right? Below we will introduce the value of weigela.
How to grow weigela: cultivation methods and precautions for weigela
Weigela has dense branches and leaves and brilliant flowers, suitable for group planting at courtyard walls and lakesides. The flower colors of weigela make people feel cheerful, so many friends also grow it at home. So what are the cultivation methods for weigela? Next, Xiao Qi will share the cultivation methods and precautions for weigela.
I. Cultivation methods for weigela
1. Soil: Weigela needs deep, moist soil rich in humus.
2. Humidity: Weigela likes light, tolerates shade and cold, and is afraid of waterlogging. The suitable air humidity is 65%-75%.
3. Temperature: The suitable growth temperature for weigela is 15°C-30°C, and the suitable temperature during the flowering period is 18°C-22°C. It tolerates low temperatures and can overwinter outdoors in the north.
4. Light: Weigela likes a warm, humid environment with plenty of sunlight.
5. Fertilizing: When potted, weigela can be grown in a mix of 3 parts garden soil and 1 part rice husk ash, plus a small amount of manure as base fertilizer. When planting, apply decomposed compost as base fertilizer, and thereafter every 2 to 3 years during the dormant period in winter or early spring, dig a trench around the roots and apply fertilizer once. During the growing season, fertilize and water timely every month. After budding in spring, gradually increase the amount of watering and keep the soil moist regularly.
6. Watering: Pay attention to watering weigela during the growing season. After budding in spring, gradually increase the amount of watering and keep the soil moist regularly. High temperature and drought in summer can easily cause leaves to turn yellow, shrink, and branches to wither. Keep sufficient moisture and spray water to cool it down, or move it to a semi-shaded, humid place for care. Water thoroughly 1 to 2 times a month to meet growth needs.
7. Pruning: Weigela has a relatively long growing period. Before winter, the small branches at the top often do not grow fully and are very likely to dry up during overwintering. Therefore, before budding each spring, the dried branches at the top of the plant as well as other old, weak, diseased, and pest-infested branches should be cut off, and long branches should be shortened. If seeds are not needed, remove the spent flower branches promptly after flowering to avoid consuming too many nutrients and affecting growth. Branches that have grown for 3 years should be cut off from the base to promote robust growth of new branches. Because the new shoots that bear inflorescences mostly sprout on 1-2 year old branches, heavy pruning of the previous year's branches is not suitable in early spring; generally only dead branches are thinned out.
8. Propagation methods: Weigela can be propagated by four methods: cuttings, layering, division, and sowing.
II. Precautions for growing weigela
1. For people who like growing weigela, one point must be noted: the seeds need to be pre-germinated before sowing. For direct sowing or 1 week before sowing, soak the seeds in cold water for 2-3 hours, remove them and place them indoors, wrap them in a wet cloth for pre-germination, and then sow; the effect is better.
2. In weigela cultivation, note that sowing is best done in windless weather with no heavy rain in the near future, and the seedbed surface should be leveled and finely prepared. The sowing method can be broadcasting or drilling on the bed surface, with a sowing rate of 2 g/sq m. After sowing, the soil cover thickness must not exceed 0.3 cm. Keep the bed surface moist within 30 days after sowing, and seedlings emerge in about 20 days.
The above isthe cultivation methods and precautions for weigelashared. During the cultivation of weigela, pay attention to watering and changing the potting soil. I hope it is helpful to everyone.
Cultivation methods for weigela
Weigela is also known as five-color crabapple, mountain sesame, and sea fairy flower. It is a deciduous shrub of the genus Weigela in the Caprifoliaceae family, with dense branches and leaves and brilliant flowers. The flowering period can last more than two months. It is suitable for group planting at courtyard walls and lakesides, and can also be used as a flower hedge or in grouped plantings at the edge of woods, or dotted among rockeries and slopes. Now let us take a look at the cultivation methods for weigela.
Growth habits of weigela
Weigela is distributed in Heilongjiang, Jilin, Liaoning, Inner Mongolia, Shanxi, Shaanxi, Henan, northern Shandong, northern Jiangsu, and other places in China. It grows under mixed forests or in mountaintop shrub thickets at an altitude of 100-1450 m. It likes light, tolerates shade and cold, and has low requirements for soil. It can tolerate poor soil, but grows best in deep, moist soil rich in humus. It is afraid of waterlogging. It has strong sprouting ability and grows rapidly.
Propagation methods for weigela
1. Sowing: Weigela seeds can be harvested from September to October. For direct sowing or 1 week before sowing, soak the seeds in cold water for 2-3 hours. Sow in windless weather with no heavy rain in the near future, and the seedbed surface should be leveled and finely prepared. The sowing method can be broadcasting or drilling on the bed surface, with a sowing rate of 2 g/sq m. After sowing, the soil cover thickness must not exceed 0.3 cm. Keep the bed surface moist within 30 days after sowing, and seedlings emerge in about 20 days.
2. Cuttings: Variant types of weigela should be propagated by cuttings, as seed propagation makes it difficult to maintain the traits after variation. The ground temperature should be 25°C-28°C, the air temperature should be 20°C-25°C, the air humidity in the shed should be 80%-90%, and the light transmittance should be about 30%. Roots can form in 50-60 days, with a survival rate of about 80%.
3. Layering: Weigela can be propagated by layering during the growing season by pressing branches into the soil. Usually after flowering, select lower branches for layering. Lower branches easily become prostrate, and roots readily form and survive at the nodes.
4. Division: Division propagation of weigela is usually carried out in early spring and autumn and winter. It is generally done around budding in spring in combination with transplanting. Dig out the whole plant, divide it into several clumps, and plant them separately.
