How to grow potted lavender? Cultivation methods and maintenance matters

Lavender pot cultivation method

1. Suitable soil

Potted lavender has relatively high requirements for soil. It is suitable to be planted in fertile soil with deep, loose soil and good drainage. It particularly likes soil containing silicon and calcium. Generally, it cannot be planted in acidic or alkaline soil, which is not conducive to its growth and development.

2. Water appropriately

Potted lavender does not require much water and is not tolerant of waterlogging. When watering, wait until the soil is dry before continuing to water. The best time to water is in the morning, so that you can effectively avoid the sun. At the same time, do not spill water on the leaves. Provide sufficient water in spring, an appropriate amount but not too much in summer, and use sufficient snow in winter to maintain normal moisture.

3. Appropriate fertilization

Potted lavender is a fertilizer-loving plant. 1-2 year old seedlings are mainly fertilized with potassium and phosphorus fertilizers, while lavender over 3 years old is mainly fertilized with nitrogen or phosphorus fertilizers. Organic fertilizers should be used as the main fertilizer at ordinary times, and should be applied every 3-4 weeks during the growth period to facilitate normal growth and development.

4. Adequate lighting

Potted lavender also likes sunlight, especially during the development period. The daily light exposure time should not be less than 4 hours. If it is maintained in a dark environment, the lavender will develop poorly and age prematurely. If the light is strong in summer, it cannot be exposed directly to the sun. Half of the sunlight should be blocked and it should be ventilated frequently.

5. Suitable temperature

Potted lavender likes a cool environment. The most suitable temperature for its growth is 15 to 25 degrees. It can also grow at 5 to 30 degrees, but the temperature cannot exceed 35 degrees, otherwise the stems and leaves on the top of the plant will become withered and yellow. In northern regions, the temperature cannot be too low. If it is kept below 0 degrees for a long time, it will gradually enter a dormant state.

Lavender care precautions

1. Change the pot in time

Lavender grows relatively fast and will gradually grow larger, so you need to change to a slightly larger flowerpot to provide it with enough space to grow.

2. Prevent diseases

Lavender is more susceptible to root rot. To avoid this, you can irrigate the roots with a diluted solution of carbendazim or thiophanate-methyl every month. In addition, leaf spot disease is also prone to occur in July and August, which requires spraying Bordeaux mixture for prevention and control, or spraying with 500-800 times diluted mancozeb.
