Pinching or “topping” young dahlias is highly recommended, including dinnerplate dahlias. Pinching refers to the act of removing the top growth or terminal bud of a plant, which stimulates branching and results in a bushier plant with more flowers. This technique is particularly beneficial for dahlias as it helps to strengthen the stems and create a more compact and attractive plant overall.
When it comes to dinnerplate dahlias, which are known for their large and showy blooms, pinching becomes even more important. These varieties often have long stems that can be prone to bending or breaking under the weight of the heavy flowers. By pinching the plants when they are young, you encourage the growth of additional stems, which helps to support the weight of the flowers and prevent them from flopping over.
To pinch dinnerplate dahlias, simply wait until the plant has developed a few sets of leaves and is starting to grow. Using your fingers or clean pruning shears, remove the top portion of the main stem, just above a set of leaves or leaf nodes. This will stimulate the growth of side shoots and encourage a more bushy and compact plant.
It’s important to note that pinching should only be done once the plant has established a strong root system and is actively growing. Typically, this is done in the early stages of growth, when the plant is about 6-8 inches tall. Pinching too early or too late in the season may not yield the desired results.
In my personal experience with growing dinnerplate dahlias, I have found that pinching is a crucial step for achieving healthy and robust plants. By pinching early on, I have noticed a significant increase in the number of flowers produced and a sturdier overall plant structure. It also helps to distribute the energy and resources of the plant more evenly, resulting in a more balanced and aesthetically pleasing growth pattern.
In addition to pinching, it’s also important to provide proper support for dinnerplate dahlias as they grow. This can be done by staking the plants or using other support systems such as cages or trellises. By combining pinching with adequate support, you can ensure that your dinnerplate dahlias not only have a stunning display of large flowers but also maintain their structural integrity throughout the growing season.
Pinching dinnerplate dahlias is highly recommended to promote stronger, bushier plants with more flowers. This technique helps to strengthen the stems, prevent bending or breaking, and create a more compact and attractive plant overall. Combined with proper support, pinching can greatly enhance the growth and beauty of dinnerplate dahlias in your garden.
