Lavender temperature and light management

What are the aspects of lavender management? Lavender cultivation requires all aspects to be beautiful and charming, so its daily management becomes extremely important.

Lavender temperature and light management

Temperature and light management of lavender

Lavender loves sunlight, and the place where it is potted requires sufficient sunlight. It is cool and is afraid of high temperatures and humidity. Controlling temperature, light and moisture is the key.

The top stems and leaves will wither and turn yellow if the temperature is higher than 38~40℃ for a long time, and the heat and humidity cannot be tolerated. In summer, it needs to be moved to a place out of direct sunlight, or a sunshade net with a light transmittance of 50% should be used. Shade, avoid direct sunlight, and increase ventilation to lower the ambient temperature and keep cool, so that you can survive the hot summer safely.

According to different lighting requirements in different periods, light should be exposed at the right time. For example, full sunlight should be ensured as much as possible in winter and spring. Lavender is a long-day plant. Light plays an extremely important role in its growth and development and the formation of aromatic oils. Excessive shading will cause excessive growth and make it susceptible to disease.

How to water lavender

Potted plants If water accumulates around the roots of lavender for a long time, the roots of lavender will easily rot and die. If the pot soil remains dry for a long time, it will also be detrimental to plant growth and even cause it to die.

Therefore, we should master the principle of "don't water if it's dry, water thoroughly if it's dry". When the leaves of potted lavender are slightly wilted, start watering. Normally, keep the surface of the pot soil dry and the interior of the pot soil moist. For degrees.

Watering in summer should be done in the morning or evening to avoid high temperatures. Be patient when watering. Pour water from the edge of the flower pot. Do not splash the water on the leaves and flowers, otherwise they will rot easily. And breed pests and diseases. The amount of potted soil for potted lavender is limited, so it is especially important to water it at the right time and in the right amount.

How to fertilize lavender

Lavender It is resistant to barrenness and does not require high fertilizers. From March to May, water-soluble quick-acting fertilizers, such as 1% to 2% urea or compound fertilizers, can be used. From June to August, phosphorus and potassium compound fertilizers are the main fertilizers. Do not use too much nitrogen fertilizer. Easy to cause excessive growth. When repotting in winter, add bone meal and superphosphate to the pot soil as base fertilizer.

Lavender pruning

In order Make the potted lavender plant beautiful in shape, with an appropriate ratio of flowers and leaves, and the height of the newly grown inflorescences should be consistent. After flowering, pruning must be carried out in time. The plant can be pruned to 2/3 of its original size. The plant will be stronger and conducive to growth. During the hot summer period, pruning should not be too heavy and do not cut into the lignified parts to avoid plant weakness and death. Usually, cut off dry, leggy and messy branches at any time. Appropriate pruning in late summer and early autumn can promote new branches and adjust the plant shape, such as hemispherical, spherical, square column, etc.

Main pest and disease control

Lavender The main disease is root rot. In high temperature and high humidity environments, ventilation should be strengthened to keep the air dry.

Especially from June to October, the pots should be turned over in time after rain, and attention should be paid to preventing water accumulation in the pot soil.

In the early stage of the disease, roots can be irrigated with 800 times solution of chlorothalonil and carbendazim once a month.

Common insect pests include red spider mites and aphids. When aphids are harmful, you can spray 50% pirimicarb 2000-3000 times liquid or 10% cypermethrin 2000-3000 times liquid once a week for 2 consecutive times times; when there is damage from red spider mites, you can spray it with 2000 times of Cromexate solution, once a week, and spray 3 times in a row. When spraying, you should be careful, and spray both the surface and the back of the leaves.
