When the water is thoroughly watered, the soil should be dried before giving water, with the surface culture medium dry, the internal moisture for the degree, and the leaves wilting slightly. Water in the morning, avoid the sun, do not splash water on leaves and flowers, otherwise it is perishable and breeds the Red Sea.

A continuous humid environment will cause the roots not to breathe enough air and grow poorly, or even suddenly die of the whole plant, which is often the reason for the failure of lavender cultivation.

How to bask in the sun in lavender potted plants

Lavender is an all-day plant, which needs plenty of sunshine and humid environment. The environment that can give full sunshine is better. One tree grows in half a day, but flowering is rare. Summer should cover at least 50% of the sun and increase ventilation to lower the ambient temperature. Lavender can grow well on flat land in winter and should be cultivated under full-day sunlight.

Third, the temperature requirements of lavender pot.

Lavender is semi-heat-resistant, cool, warm in winter and cool in summer.

The suitable temperature for growth is 15-25 ℃, and it can grow at 5-30 ℃.

The limiting temperature is above 35 ℃, and the top stems and leaves are withered and yellow for a long time higher than 38-40 ℃.

In northern China, dormancy begins when it is below 0 ℃ for a long time in winter, and the seedlings can withstand the low temperature of-20 ℃ to-25 ℃ during dormancy.

Fourth, the pruning of lavender pot

Lavender flowers are rich in essential oil, mainly flowers or inflorescences, in order to facilitate harvest, some small inflorescences in the early stage of cultivation might as well use large scissors to make the whole flat, and the new 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. Must be pruned after flowering, the plant can be trimmed to the original 2/3, the plant type will be stronger and conducive to growth. Pruning in the cold season such as spring, autumn 10, generally pruning in spring, pruning in autumn will affect the cold resistance.
