A Detailed Guide to Snapdragon Cultivation Techniques: Management Points from Sowing to Blooming
Snapdragon is a perennial herbaceous plant in the Scrophulariaceae family, with plants reaching about 50 cm in height. Its flowers are vivid and brightly colored, giving it extremely high ornamental value. Because the flowers closely resemble goldfish, it got its name. Snapdragon also has considerable medicinal value, able to clear heat and detoxify, cool the blood and reduce swelling, and it is an oilseed crop as well. So how should snapdragon be planted? Below, the editor brings you the cultivation techniques for snapdragon. Let's take a look!
1. Sowing Environment
Snapdragon has strong cold tolerance and is not suited to growing in high-temperature environments. It is best planted in a spot with full sunlight or partial shade. Choose soil with normal drainage, deep, loose, soft layers and strong permeability. Pay attention to soil fertility; it should not be too poor, otherwise the growth of snapdragon will be affected to some degree. After choosing the site, do the soil preparation work well, carrying out deep plowing and disinfection to prevent residual pathogens from harming snapdragon growth. Then apply enough base fertilizer, mainly fully decomposed farmyard manure, to meet the abundant nutrients snapdragon needs for growth.
2. Timely Sowing
The main planting method for snapdragon is sowing. Spring and autumn are the best times to sow snapdragon, though this varies depending on the growing region. In the Yangtze River basin, sowing is generally done in autumn; autumn seedlings have stronger growth ability and a higher flowering rate than spring seedlings. Before sowing, to promote germination, the seeds should be soaked and pregerminated in a solution such as gibberellin. When sowing, pay attention to sowing density. After sowing, cover with fine soil and press it down firmly to ensure full contact between seeds and soil, then water thoroughly to keep the soil moist. Control the temperature well to prevent water from evaporating too quickly and improve the seed germination rate.
3. Seedling Management
After sowing, under normal management, germination occurs in about a week. Then the plastic film should be removed in time to promote the seedlings pushing through the soil and receiving light. During seedling growth, thinning should be carried out about twice to ensure every seedling can grow vigorously. When the seedlings have grown about 5 true leaves, they can be transplanted and planted out. When transplanting, try to transplant with soil to prevent lack of water from affecting seedling development. Before transplanting, do a series of preparations for the planting field, control the planting density well and dig the planting furrows. After planting, water thoroughly, do the topdressing work well, strengthen field management, and improve the survival rate after planting.
4. Field Management
Snapdragon contains rhizobia and has a strong nitrogen-fixing effect, so when topdressing, nitrogen fertilizer may be omitted and phosphorus and potassium fertilizers are mainly sufficient. Properly applying phosphorus and potassium fertilizers can improve flower quality and enhance petal brightness, which is very important for snapdragon growth. During the growing process, pinching should be done well. Usually it is done once when the seedlings grow to about 14 cm, then again at 20 cm. This can effectively promote side branch growth in snapdragon plants, increase the flowering rate, and raise commercial ornamental value.
The above is a brief introduction to snapdragon cultivation techniques. Snapdragon cultivation is very simple, but field management work is still needed to ensure normal growth of snapdragon and avoid losses. That is all for today's introduction.
