How to Propagate Sweet Alyssum? Detailed Propagation Methods and Precautions

Sweet alyssum prefers cool, sunny conditions and also tolerates partial shade. It is highly adaptable, and artificial cultivation is not difficult. However, if rainy weather lasts too long, sweet alyssum becomes more susceptible to infection by pathogens. Friends who love sweet alyssum can propagate new plants themselves once their sweet alyssum has grown to a certain size.

Sweet alyssum

Sweet alyssum can be propagated by seed or by cuttings, but seed propagation is generally more common. In northern regions, spring sowing is typical, usually sowing seeds in a greenhouse in March to raise seedlings. Sweet alyssum seeds germinate faster than ordinary flower seeds, and seedlings emerge uniformly. The optimum germination temperature is 20°C, with seedlings emerging in about 5 days. When 3-4 true leaves have formed, transplant into pots. They bloom in June. When the summer heat arrives, growth declines and flowering is sparse; at this point, cut off the spent flowering stems and strengthen fertilizer and water management, and they will bloom again in autumn. In North China and southern regions, autumn sowing is typical, overwintering in a cold frame under protection, then potting up or transplanting in March of the following year, blooming in April.

Sweet Alyssum Pictures: Cultivation Methods and Precautions for Sweet Alyssum

Sweet alyssum, also called "little white flower," is a plant in the Brassicaceae family. It can be grown in gardens or cultivated as a potted plant. Its fragrance is pleasant, its colors are vivid, and it is especially beautiful. In a moment I will share sweet alyssum pictures with everyone, and also give everyone a comprehensive understanding of the cultivation methods and precautions for sweet alyssum.

Sweet alyssum has strong vitality. It likes sunlight but fears intense light, and it is not strict about soil requirements; normally, well-drained soil should be chosen. Before early summer, necessary pruning should be carried out, and it should be moved to a cool place. Pay attention to water supply at ordinary times, and only apply dilute liquid fertilizer. As long as these things are done well, sweet alyssum can grow healthily.

1. Humidity management

When cultivating sweet alyssum, humidity management is very important. This plant likes a dry air environment. If air humidity is too high, it becomes prone to infection by pathogens. During ordinary cultivation, it fears being rained on, and at night its leaves should be kept dry. Under ordinary indoor conditions, the temperature should not exceed 60 percent.

2. Temperature regulation

The sweet alyssum plant likes a cool climate, dislikes high temperatures, and tolerates severe cold. In winter it has low temperature requirements; as long as it is not placed somewhere with frost, it is fine. But in summer, temperature control must be paid attention to. It cannot be placed in an environment above 30 degrees, otherwise it may die from excessively high temperatures. In addition, this sweet alyssum plant grows fastest when the external temperature is between 15 and 25 degrees.

Cultivation Methods and Precautions for Sweet Alyssum

Cultivation Methods for Sweet Alyssum

Temperature

Sweet alyssum likes a cool climate and dislikes extreme heat. It is not strict about winter temperatures; as long as it is not exposed to frost, it can overwinter safely.

Summer temperatures must not be too high. If the temperature reaches as high as 30°C, it will die. The most suitable growth temperature is 15°C-25°C.

Soil

It is not strict about soil requirements. As long as the soil is loose, fertile, and well-drained, it can grow healthily.

Light

Sweet alyssum likes a sunny environment and is slightly shade-tolerant.

Therefore, apart from avoiding direct sunlight in summer, it can be placed in a sunny spot in other seasons to receive scattered light.

Watering

Sweet alyssum likes a relatively dry air environment. If rainy weather lasts too long, it is prone to infection by pathogens. It fears being rained on, and at night the leaves should be kept dry.

The most suitable relative air humidity for sweet alyssum growth is 40%-60%.

Precautions for Cultivating Sweet Alyssum

Pay attention to pruning

During the flowering process of sweet alyssum, spent flowers can be cut off along with three leaves, which can extend the flowering period.

Prevent and control pests and diseases

During the cultivation of sweet alyssum, pay attention to preventing pests and diseases. Spray 2000-fold decis or 1000-fold dichlorvos once every 10-15 days to prevent insects. Spray 700-fold carbendazim or chlorothalonil once every 7-10 days for sterilization.

Control fertilization

Sweet alyssum has relatively high fertilizer requirements, but do not fertilize randomly, do not apply concentrated fertilizer, and do not apply nitrogen, phosphorus, and potassium fertilizers in a one-sided way. Follow the principle of "light fertilizer applied frequently, small amounts with more applications, and complete nutrition."

Pay attention to rain protection

During the plum rain season, do not let it be rained on for a long time. Otherwise, excessive moisture or poor drainage can easily cause water accumulation, and may even cause the roots and stems of sweet alyssum to rot.

Pay attention to frequent ventilation and maintain air circulation, which can extend the flowering period and lifespan.
