When and How to Pinch the Top of Dahlias
This article introduces the knowledge about when and how to pinch the top of dahlias, including the following details:
When and How to Pinch the Top of Dahlias
Dahlias need to be pinched because their above-ground parts are relatively fragile and prone to lodging in strong winds. Therefore, it is necessary to pinch them during maintenance to make them grow shorter, sprout more lateral branches, which can resist lodging and also increase the number of flowers, enhancing their ornamental value. The usual time for pinching is in spring and autumn every year, as the wounds heal more easily during these seasons.
Do Dahlias Need to Be Pinched
Dahlias need to be pinched because their above-ground parts are fragile and can easily lodge in strong winds. Pinching can make them grow shorter, sprout more lateral branches to resist lodging, and increase the number of flowers for better ornamental value.
When the dahlia seedlings grow to about 5 cm high, they can be pinched at the top to control their height and prevent lodging.
Pinching dahlias means removing the top part of the plant when it reaches the desired height, and the specific operation depends on the variety of the dahlia.
Usually, about half a month after pinching, new leaves will grow, and the flowers will start to bloom from the end of July to the beginning of August.
When to Pinch Dahlias
Dahlias are usually pinched in spring and autumn each year, as this is their growing period. Pinching during this time allows their wounds to heal quickly, which is beneficial for their growth and development.
How to Pinch Dahlias - Steps and Methods
1. Pinching: When the dahlia seedlings grow to about 5 cm high, they can be pinched by removing the top part, which helps to control the height and prevent lodging.
2. Pruning branches: During the management of dahlias, it is necessary to prune them in time. If there are withered or weak branches, they should be cut off to reduce nutrient consumption and promote better ventilation and light penetration for better growth.
Precautions for Pinching Dahlias
When maintaining dahlias, attention should not only be paid to pruning but also to other aspects. For potted plants, frequent fertilization is needed for sufficient nutrients to bloom and grow better. In high summer temperatures, they should be moved to a shady place. Moreover, attention should be paid to pests and diseases, and prompt treatment is necessary to prevent exacerbation.
The comprehensive explanation provided above about when and how to pinch dahlias is hoped to be a modest contribution that can solve your problems with green plants.
