Petunia is one of the most popular flowering plants. Lush bushes with white, pink, red, purple, spotted flowers are found in city flower beds, personal plots, on the balconies of townspeople. To prolong flowering and rejuvenate the bushes, flower growers prune petunias in mid-summer.

Why prune petunia

Petunia - an unpretentious plant that delights with its lush flowering. To maintain the beauty of flowers in the middle of summer, perform a "haircut". If petunia is left unattended, the plant will begin to stretch, and the flowers will become small and dull.

Petunia pruning is performed at the stage of growing seedlings. To do this, pinch the main branches, which stimulates the formation of lateral stems. The tips of the stems are removed with fingers or scissors, after which the shoots become thicker, and the leaves acquire a rich color. In two weeks, the first buds will appear on the bush, dormant buds are activated and will quickly grow.

Petunia haircut is included in the list of mandatory procedures to give the bushes a neat shape. This method helps to create unusual shapes and change the direction of stem growth. You can give the shape of a ball or descend branches in a beautiful cascade.

Important! The formation of petunias is performed only if the stem was promptly pinned during the growing season.

Pruning the plant correctly will help if the stems are pulled out due to lack of light and improper care. Bush varieties pluck without regret, leaving only 15 cm in length, ampelous cut if desired. After pruning, the plant begins to grow with renewed vigor.

Pruning or pinching is performed exclusively on mature bushes. This stimulates flowering and allows the propagation of petunias by cuttings. 3-4 weeks after the first procedure, the lateral stems are additionally shortened to add volume. Subsequent manipulations are performed as needed, taking into account the condition of the plant.

As a result of intense flowering, petunia quickly loses strength. For their renewal, the bushes are regularly sprayed and fed once a week.

After flowering, the plant is pruned if the bushes are grown for decorative purposes. If the grower needs seeds, no pruning is done. When regular pinching does not give the expected results and the leaves turn yellow, it is recommended to trim the bushes by one third. The plant is removed from the pot along with an earthen clod and the root system is divided in half. A sharpened knife will do for this.

After dividing the rhizomes, the petunia is transplanted into larger pots, filling them with fresh soil mixture. The containers are transferred to a dark place for a week and watered regularly. For three weeks, the soil is fertilized with nitrogen, then they switch to complex feeding. After such pruning, petunia will resume flowering at the end of August and will delight with new buds until September.
