When to fertilize lavender and how to fertilize lavender

1. Fertilization time

Fertilizing lavender is mainly concentrated during its growing season. The plant grows and develops very quickly at this stage, so it needs sufficient nutrients. Insufficient nutrients will slow its development and reduce flowering. During its dormant period, you should reduce watering or stop fertilizing to avoid excessive fertilizer accumulation, which will cause fertilizer damage and harm the growth of the plant.

2. Fertilizer selection

The fertilizers applied to lavender at different times are also different. 1-2 year old seedlings should be mainly fertilizers of phosphorus and potassium, and nitrogen fertilizers should not be applied too much, otherwise it will easily grow too tall. For plants over 3 years old, more nitrogen and phosphorus fertilizers should be applied, and less potassium fertilizer should be applied to avoid affecting the quality of the essential oil. Use organic fertilizer as fertilizer and nitrogen fertilizer as top dressing to ensure better growth.

3. How to fertilize

Lavender fertilization must be combined with watering to ensure effective absorption of nutrients. If it is solid fertilizer, it needs to be applied before watering. Dig a hole in the soil, bury the fertilizer in it and fill it up. The location of fertilizer application should be away from the roots to avoid damage. If it is liquid fertilizer, you can use it directly on the roots instead of watering. Be careful not to spray it on other places.

IV. Precautions

The first thing to pay attention to when applying fertilizer is to control the amount. Although fertilizer can help growth, applying too much fertilizer is not only not conducive to plant development, it may also burn its roots. In addition, do not apply fertilizer when the plant is in bloom, otherwise it will easily cause the flowers to fall off.
