During cultivation, water according to soil dryness and moisture, but avoid water accumulation in the pot. The suitable growing temperature is around 26-28°C. During this period, an appropriate amount of urea, phosphate fertilizer, and potassium fertilizer can be applied. Pesticides such as liquid jishijing, snail bait, and Bordeaux mixture can be used to control pests and diseases.

1. Choosing Soil

Angelonia does not have high soil requirements. It is suitable for planting in a full-sun environment, as well as in slightly shaded, well-drained sandy soil, and grows best in alkaline soil.

2. Reasonable Lighting

1. After Angelonia is planted out in summer, appropriate shading is needed, and after the seedlings recover, they can gradually be exposed to light.

2. At noon in summer, avoid direct exposure to sunlight, and appropriate sun-shading measures are needed. In the evening, water thoroughly, which helps balance the transpiration under strong daytime light.

3. Timely Watering

Angelonia likes to grow in a moist environment. During cultivation, water according to soil dryness and moisture, but water accumulation should not occur in the pot.

4. Suitable Temperature

The suitable temperature for Angelonia during growth is 26-28°C. It can relatively tolerate short periods of high temperatures above 35°C. When the temperature is too high, ventilation or spraying can be used to lower the temperature.

5. Regular Fertilization

1. Angelonia likes fertilizer. After potting, a small amount of fertilizer can be applied 10-15 days later, and then 1 application of fertilizer about every 15 days.

2. Before open-field planting, decomposed organic fertilizer can be applied into the soil as a base fertilizer. During the growth period, 2-3 topdressings can be applied along with irrigation. About 5 kg of urea can be applied per mu, and during the flowering period, phosphate fertilizer and potassium fertilizer can be applied 1-2 times.

6. Pest and Disease Control

1. The more common insect pests of Angelonia include whiteflies, aphids, slugs, and so on. When whiteflies and aphids occur, generally liquid jishijing 600-800 times dilution, 5% acetamiprid 800 times dilution, or 25% Actara (thiamethoxam) 2500-5000 times dilution can be used for control.

2. When slugs occur, 3.3% snail bait, or 3% calcium arsenate mixture powder can be used, applying 1 gram of pesticide per square meter for control.

3. The more common diseases of Angelonia include downy mildew, leaf spot, and so on. When downy mildew and leaf spot occur, generally 0.1%-0.2% copper sulfate solution or 1% Bordeaux mixture spray can be used for control.

7. The Value of Angelonia

Angelonia has small flowers, elegant flower colors, a large number of flowers, and a long ornamental period. It also has very strong adaptability to hot and high-temperature climates. It is one of the herbaceous flower varieties very suitable for summer planting. It can be planted in the ground, in pots, and can also be planted in container combinations or in wetlands.
