When do petunias bloom?
This article provides a detailed explanation of when petunias bloom and an introduction to the flowering period of green plants and flower planting. Next, the editor will introduce the content.
Commonly known as petunia, the Chinese name for the plant is Bitongqie, also known as dwarf petunia, dwarf trumpet, and shuttlecock flower. The blooming period of petunias is usually from April to October, with an annual flowering period of up to three months. Good maintenance during the flowering period can promote more and longer-lasting blooms. Although the flowers of petunias resemble those of the morning glory, they are not even in the same order in terms of kinship. There are many varieties of petunias, with different varieties having different flower colors and shapes. Below is an introduction to the flowering period management of petunias.
1. Proper watering
Overly moist 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 prevent the plants from getting wet, and the amount of water should be determined based on the dryness of the soil. Therefore, it is essential to avoid waterlogging during the flowering period, as this can shorten the blooming time and cause root rot.
The amount of water should be moderate, keeping the soil slightly moist. Watering during the flowering period should be done only when the soil is dry, and it should be thorough, without getting water on the flowers. When temperatures are high, it is necessary to increase watering or sprinkle water appropriately. The timing of watering should avoid the evening, with morning watering being the most effective.
2. Sufficient sunlight
After sowing, petunias can bloom in about 100 to 150 days. If sown in autumn and winter, they can produce flower buds in spring. Petunias are long-day plants, and adequate sunlight can promote bud formation, resulting in more flowers. Insufficient light can cause the stems and leaves to grow excessively and the flower color to fade.
Sunlight time should be maintained at about 12 hours, and if the conditions are not good, incandescent lighting can be increased. In summer, it is important to shade the plants to prevent sun exposure.
3. Proper fertilization
The flowering period of petunias also requires regular and appropriate fertilization, with fertilizing every 10 to 12 days. During the bud formation period, additional phosphorus fertilizer should be applied to produce more and brighter flowers. Fertilizer should not come into contact with the roots and can be sprayed diluted fertilizer on the leaves. 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 a diluted solution of phosphorus and potassium fertilizer, to help the plant better survive the winter.
4. Pruning
If the flower buds are small after they form, they should be cut off promptly to promote reblooming. After flowering, it is appropriate to prune the spent flowers and withered leaves. After flowering, you can also directly cut off one-third of the top of the plant to promote new flower bud growth, which will bloom again shortly and extend the flowering period with a large number of flowers.
If seeds are not needed for sowing after the flowers fade, it is also necessary to prune the spent flowers and shorten the branches.
