[how to raise lavender flowers] how to raise lavender

Lavender has always been a favorite flower plant, the whole plant has a fragrant smell, leaf-shaped flowers beautiful and elegant, blue-purple inflorescences long and beautiful, suitable for flower path cluster planting or strip planting, can also be potted ornamental, but also has a good mosquito repellent effect. Many families grow lavender will choose seed sowing method, it is not easy to cultivate plant seeds, especially the survival rate of lavender seeds is still relatively low, then how to plant lavender seeds? What are the planting methods and techniques of lavender seeds? Let's learn about this:

How to raise lavender flowers

Temperature:

In the warm winter and cool summer environment, the most suitable temperature for growth is 15-301C, so spring and autumn are the best periods for plant growth. It is more cold-tolerant, especially in the seedling stage. It can endure the low temperature of-5cm Mel 8X: when there are 4 pairs of leaves. The plant goes into dormancy when the winter temperature drops below 01C, but the soil can endure the low temperature of-2 (TC), and the pot is planted indoors to keep warm in winter. Avoid high temperature and extreme heat, semi-dormant in summer, and muggy weather is the most likely to lead to plant death. However, as long as the plant is well ventilated, although the plant grows slowly, it will not die from high temperature. When the temperature exceeds 3 (TC), besides strengthening ventilation, measures such as shading and environmental water spraying should be taken to create a cool environment.

Lighting:

Xiguang, it is usually best to put the pot plant in a place where you can see the sun all day and have good ventilation. Lack of light will affect flowering and essential oil production. However, when the summer temperature is higher than 30X:, the strong sun should be avoided and shading measures should be taken to cover about 50% of the sun.

Watering:

Like the dry soil environment, avoid wet and waterlogging. Do not have too much water, otherwise the root system is easy to suffocate, which is the most common problem of growing lavender. During the growth period, tearful water should grasp the principle of "no dry, no watering"; at the same time, 7JC should avoid pouring on the leaves, because there are villi on the leaves, such as water retention on them, the leaves are easy to rot. If the leaves are accidentally stained with water, the plant should be moved to the ventilated place in time to dry as soon as possible. Plum plants should be placed in shelter during the rainy season, otherwise they will not only reduce oil production, but also cause rotting roots and death. Avoid humid and muggy weather, control watering when high temperature in summer, and strengthen ventilation. High temperature and high humidity can easily lead to plant death. It is necessary to control watering in winter to keep the basin soil relatively dry.

Trim:

Lavender flowers are the most abundant in essential oil, and flowers or inflorescences are mainly used. In order to facilitate harvest, some small inflorescences at the initial stage of cultivation might as well be leveled with large scissors, and the newly grown inflorescences are highly consistent, which is conducive to a harvest. Some varieties can reach a height of up to 90 centimeters, and this method is also used to make the plants low and make them more branched, blossom and increase the yield. After flowering, the plant must be pruned, and the plant can be pruned to the original 2umber 3, so that the plant type will be stronger and conducive to growth. Pruning in the cold season such as spring and autumn, generally pruning in spring, pruning in autumn will affect the cold resistance. Be careful not to cut the lignified part when pruning, so as not to weaken the plant and die.

Planting and turning pots:

When growing lavender in the Yangtze River basin, we should choose heat-resistant species, such as toothed lavender, French lavender, sweet lavender (a hybrid of narrow-leaf lavender and toothed lavender) and so on. When the seedlings grow out of 4 or 6 true leaves, they should be put into the pot. Like well-drained, neutral or alkaline sandy loam, the matrix can be prepared with rotten leaf soil, vermiculite, perlite, coconut bran and other materials. If the soil is acidic, it should be mixed with some lime or coal cake ash and adjusted to the soil pH to neutral or weakly alkaline. The basin should be turned once every spring.

Pest control:

Because of its unique aroma and oil, there are few diseases and insect pests, and Fusarium wilt may occur at high temperature.

Lavender seed price:

We naturally have to buy lavender seeds before planting. What we want to know is the price of lavender seeds. The price of lavender seeds is very different from the varieties of lavender. Now the lavender seeds bought online are generally calculated by grains, 20 to 30 seeds cost about 5 yuan, and the prices sold in different regions are not the same.
