4. Precautions

Lavender fertilization is mainly concentrated during the growth period, that is, spring, summer and autumn. For 1-2-year-old seedlings, choose phosphorus and potassium fertilizers instead of nitrogen fertilizers to avoid excessive growth. Plants over 3 years old should be fertilized with more nitrogen and phosphorus fertilizers. Too much potassium fertilizer will affect the quality of essential oils. In addition, fertilization should be combined with watering to help the fertilizer be better absorbed.

1. Fertilization time

Fertilizing lavender mainly focuses on its growth period. At this stage, the plant grows and develops very quickly, so it needs sufficient nutrient supply. If the nutrients are insufficient, it will develop slowly and flowering will be reduced. During its dormant period, watering should be reduced or fertilizer should be stopped to avoid excessive accumulation of fertilizer, causing fertilizer damage and harming the growth of the plant.

2. Fertilizer selection

Different The fertilizers applied to lavender vary from time to time. 1-2 year old seedlings should mainly use phosphorus and potassium fertilizers. It is not advisable to apply too much nitrogen fertilizer, otherwise they will easily grow leggy. For plants that are more than 3 years old, more nitrogen and phosphorus fertilizers should be applied, and less potassium fertilizer should be applied, so as not to affect the quality of essential oils. Most of the fertilizers are organic fertilizers, and nitrogen fertilizers are used for top dressing, so that they can develop better.

3. How to fertilize

Lavender Fertilization must be combined with watering to ensure effective absorption of nutrients. If it is a 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 fertilizer should be applied away from the roots to avoid damage. If it is liquid fertilizer, you can directly irrigate the roots instead of watering. Be careful not to spray it in other places.

IV. Precautions

Fertilization The first thing to pay attention to is to control the dosage. Although fertilizer can help growth, applying too much fertilizer is not only detrimental to plant development, but may also burn its roots. In addition, do not fertilize the plants when they are blooming, otherwise it will easily cause flower drop.
