1、 Fertilization time

Fertilization of lavender is mainly concentrated in its growth period. At this stage, the plant grows and develops rapidly, so it needs sufficient nutrient supply. If the nutrient is insufficient, it will slow down its development and reduce flowering. In its dormancy period, it is necessary to reduce watering or stop fertilizer, so as not to accumulate too much fertilizer, form fertilizer damage and endanger the growth of plants

2、 Fertilizer selection

The fertilizer applied to lavender in different periods is also different. 1-2-year-old seedlings should be mainly phosphorus and potassium fertilizer, and nitrogen fertilizer should not be applied more, otherwise it is easy to grow in vain. For plants over 3 years, more nitrogen and phosphorus fertilizer should be applied, and less potassium fertilizer should be applied to avoid affecting the quality of essential oil. Organic fertilizer is mostly used for fertilizer, and nitrogen fertilizer is selected for topdressing, so as to better develop

3、 How to fertilize

Lavender fertilization must be combined with watering, so as to ensure the 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. The fertilization position should be far away from the root to avoid damage. If it is liquid fertilizer, it can directly irrigate the root instead of watering. Be careful not to spray it in other places

4、 Precautions

The first thing to pay attention to is to control the amount of fertilizer. Although fertilizer can help growth, excessive fertilization is not only detrimental to plant development, but also may burn its roots. In addition, do not apply fertilizer when the plant is flowering, otherwise it is easy to cause flower falling
