Also known as Chinese name Bitongqie, petunias are also called dwarf petunias, dwarf trumpets, and shuttlecock flowers. The flowering period of petunias often spans from April to October, with an annual flowering period of up to three months. Proper maintenance during the flowering period can promote more and longer-lasting blooms. Although petunias resemble morning glories in appearance, they are not even in the same order in terms of kinship. There are many varieties of petunias, and different varieties have different flower colors and shapes. Next, I will introduce the flowering period management methods for petunias.
1. Proper watering
Overly wet potting soil can cause the plant to grow too tall, and excessive rainfall during the flowering period can dilute the color of the flowers. If it rains during the flowering period, it is important to avoid getting wet, and the amount of water should be determined based on the dryness of the soil. Accumulated water should be avoided during the flowering period, as it can shorten the flowering period and cause root rot.
The amount of water should be moderate, keeping the soil slightly moist. Watering during the flowering period should be done when the soil is dry, and the watering should be thorough, avoiding getting water on the flowers. When temperatures are high, it is appropriate to increase watering or lightly spray water. It is best to avoid watering in the evening, and early morning is the best time for watering.
2. Sufficient sunlight
After sowing, petunias can bloom in about 100 to 150 days. If sown in autumn or winter, they can produce flower buds in spring. Petunias are long-day plants, and adequate sunlight can promote the formation of flower buds, resulting in more blooms. Insufficient sunlight can cause the branches and leaves to grow too tall and the flower color to fade.
The duration of sunlight should be maintained at about 12 hours, and if sunlight conditions are poor, incandescent light can be added. In the summer, it is important to shade the plants to prevent exposure to direct sunlight.
3. Proper fertilization
The flowering period of petunias also requires regular and appropriate fertilization, with fertilization every 10 to 12 days. During the bud formation stage, it is important to add phosphorus fertilizer to ensure more and brighter flowers. Fertilizer should be avoided from getting on the roots and can be sprayed on the leaves after dilution. During the summer flowering period, fertilizing should not be done at noon but rather in the early morning or evening.
After the flowering period, it is also necessary to apply additional fertilizer, such as diluted phosphorus-potassium fertilizer, to help the plants better survive the winter.
4. Pruning
If the flower buds are small after the buds form, it is important to剪掉 the buds to promote reblooming. After flowering, it is appropriate to prune the withered flowers and yellow leaves. After flowering, you can also directly cut off one-third of the top of the plant to promote the formation of new flower buds, which will bloom again shortly, extending the flowering period and increasing the number of flowers.
If seeds are not needed for sowing after the flowers fade, it is also necessary to prune the withered flowers and shorten the branches.
