Lavender is sun-loving.As a long-day plant, it needs to receive a long time of light in the flower bud differentiation period.If the light time is insufficient, it will delay its flowering period and affect the flowering of plants.It should be noted that this plant is not tolerant to strong light, so it needs proper shade in summer, especially at noon to avoid sunlight, so as not to sunburn its leaves.
1. Soil: The root system of lavender is very developed, and it is usually planted in a place with a deep soil layer.If it is potted, you need to use loose and fertile soil, which is more conducive to the growth of plants.In order to increase its drainage, broken tiles can be placed on the bottom of the basin.In addition, a small amount of base fertilizer can also be mixed into the pot soil to provide a little nutrient.
2. Temperature: Lavender has strong heat resistance and cold resistance, but it can grow and develop only under suitable temperature.Seeds germinate at 8-12 degrees Celsius, and when the temperature reaches 12-15 degrees Celsius, the branches of the plant begin to grow.When it reaches 16-18 degrees Celsius, it will grow buds and blossom at about 20 degrees Celsius.
3, watering: lavender prefer dry environment, the demand for water is not a lot.In the returning green stage and budding stage of plants, due to the rapid growth rate, it also needs relatively sufficient water.To its flowering period, watering should be reduced, so as not to cause the phenomenon of falling flowers.Similarly, it does not need much water to go dormant in winter.
4. Fertilization: In addition to applying base fertilizer during planting, additional fertilizer can also be applied properly during the growth period of lavender.Fertilization is usually applied before and after flowering, mainly phosphorus and potassium fertilizer before flowering, which can promote flowering of plants, and nitrogen fertilizer after flowering, so as to restore plant growth.
