How to propagate Verbena

1. Methods of propagating Verbena

1. Cuttings

You can start taking cuttings of petunias in May and June, choosing a temperature around 15 degrees. Choose strong old branches of petunia, cut them into strips of five to six centimeters, and insert them into loose and moist sandy soil. Be sure to provide shade, and only allow a little sunlight after 2 to 3 days. A small amount of gentle light will encourage the growth of the cuttings, and roots and new shoots will appear in about two weeks. When the seedlings have grown five or six leaves, they can be transplanted and planted elsewhere.

2. Planting seeds

The germination rate of petunia seeds is very low, less than half. Moreover, the seedlings grown from seeds germinate slowly, have low quality, and do not grow well.

The seeds should be sown at a temperature of about 16 degrees. After planting, they should be placed in a dark place immediately. While keeping the soil moist, make sure the air is not too dry. Generally, the seeds are sown in spring, and the petunias will bloom around July.

3. Daily management

(1) Fertilization

During the growing period of verbena, fertilizer should be applied for good development. The frequency is about once every half a month, and the fertilizer applied should not be too concentrated.

(2) Watering

The roots of petunias are shallow, so special attention should be paid to the amount of water to avoid affecting the growth of petunias. During the hot summer, control the amount of watering to prevent drought. Watering too much or too little will be harmful to the growth of petunias. If there is too much water, the stems of the plants will grow thin and long, and the number of flowers will decrease. If you water too little, the plants will not grow well and will produce seeds prematurely.

Verbena has strong disease and insect resistance. As long as there is adequate nutrition and proper water supply, the plant will grow healthy and strong, and diseases and insect pests will rarely occur.

2. Precautions during the cultivation of Verbena

Verbena prefers a cool environment and cannot tolerate extremely hot or cold environments. High temperatures and excessive direct sunlight will cause its leaves to shrink, branches to shorten, and growth to slow.
