How to grow verbena

1. Soil

Verbena is not very demanding on the soil, but it needs to be planted in soil that is breathable and well-drained. Avoid continuous cropping, otherwise it will lead to the degeneration of the variety and slow growth, affecting its ornamental value.

2. Temperature

It likes a warm environment, and 20-30℃ is the most suitable temperature for its growth. It is not cold-resistant and grows slowly below 10℃. During the winter period, breeding needs to be carried out in a greenhouse, and the minimum cultivation temperature must not be lower than 0℃.

3. Lighting

It requires full-day sunlight and cannot grow in shaded conditions. Cultivating it in a semi-sunny or shaded area will result in poor growth and slow growth.

4. Fertilization

Top dressing should be applied in time according to its growth conditions. Fertilizer can be prepared in a ratio of about 1:20 of decomposed cake fertilizer to diluted manure, or low-concentration compound fertilizer can be used.

5. Watering

It tolerates drought, but a relatively humid environment is beneficial to its health. A moderate amount of water is required in the early stages of cultivation. Daily watering should be controlled once every 4-5 days, and the soil should not be too wet. During the rainy season, attention should be paid to drainage to prevent root rot and death.

6. Notes

1. Other weeds should be removed in time, but avoid spraying herbicides.

2. Chemical pesticides such as parathion, methyl parathion, and carbendazim can be used for disease and insect control.
