How to Pinch Dahlias for Optimal Growth
How to Pinch Dahlias?
Pinching dahlias is a beneficial practice that results in stronger, bushier plants with more flowers.
The best time to pinch dahlias is when they are about 10″ tall and have at least 4 sets of leaves on the center stalk.
Pinching stimulates lateral buds to develop into new stems, redirecting the plant’s energy towards producing stronger stems and leaves.
Although it may delay flowering by a week or two, the plants will be fuller, stronger, and easier to manage.
Additionally, cutting flowers for bouquets during the summer and early fall has a similar effect to pinching, keeping the plants bushy and stimulating more bud production.
To support full-size dahlias, staking is recommended.
Stakes such as steel T-posts or 2″ square hardwood stakes should be placed at 3 to 4 foot intervals to prevent sagging of the string.
Different options for stakes include wood stakes, bamboo poles, metal rebar, and tomato cages.
Time invested early in the growing season to pinch dahlias and provide support will promote healthy plants.

Did You Know?
1. Did you know that dahlias were first discovered in Mexico in the 16th century by Spanish conquistadors? They were actually used by the Aztecs for medicinal purposes and as a source of food!
2. One interesting tidbit about pinching dahlias is that by physically removing the center terminal bud, you can encourage bushier growth and more abundant flowering. This technique is called “pinching out” and is commonly used by dahlia enthusiasts.
3. In the language of flowers, dahlias symbolize dignity and elegance. So next time you give someone a bouquet of dahlias, you’re actually conveying a message of grace and sophistication!
4. While dahlias are primarily known for their vibrant and striking colors, there is a rare variety called Café au Lait that has pale, creamy tones. This particular dahlia has gained immense popularity because of its unique and soft coloration.
5. Dahlias come in a wide range of shapes and sizes, but one especially intriguing type is the “pompon” dahlia. Resembling a perfect sphere, these small and adorable flowers are typically no larger than a ping pong ball and are often used in floral arrangements to add a touch of cuteness and charm.
Pinching Dahlias For Stronger Plants
When it comes to growing dahlias, pinching or “topping” young plants is a crucial technique that can significantly improve their growth and appearance. By pinching dahlias, you can encourage stronger and bushier plants that produce more flowers. This simple method involves removing the terminal bud of the plant, which redirects the plant’s energy towards developing new stems and leaves.

Timing And Technique For Pinching Dahlias
To achieve the best results, it is important to know when and how to pinch dahlias. Generally, the ideal time to perform this technique is when the dahlia plant reaches around 10 inches in height and has at least four sets of leaves on the central stalk. This ensures that the plant is mature enough to handle the pinching process without being overly stressed.
To pinch a dahlia, locate the terminal bud at the top of the main stem, just above the highest set of leaves. Using sharp and clean pruners or scissors, carefully remove the bud by making a clean cut. It is crucial to make the cut just above a set of leaves to allow for new stems to develop.
The Benefits Of Pinching Dahlias
Pinching dahlias offers several benefits that make the extra time investment worthwhile. By removing the terminal bud, you stimulate the development of lateral buds, which ultimately results in the growth of new stems. This branching effect gives the plants a bushier appearance and allows for more flower production.
While it may take an additional week or two before the plant starts to bloom, the outcome is well worth the wait. Pinched dahlias will have stronger stems, fuller foliage, and will be easier to manage as they grow. This improved structure also makes them more resistant to wind and adverse weather conditions.

Pinching Vs Cutting Flowers: Which Is Better?
Another approach to achieving bushier dahlias is through the regular cutting of flowers during the summer and early fall. This practice has a similar effect to pinching, as it redirects the plant’s energy towards producing new stems and leaves. By cutting the flowers for bouquets, you not only enjoy beautiful arrangements but also stimulate the growth of lateral buds, enhancing the overall aesthetic and health of your dahlia plants.
However, it is important to strike a balance between cutting flowers and allowing some blossoms to develop fully. While cutting flowers helps maintain a bushy appearance, allowing some flowers to bloom and fade naturally can also contribute to the plant’s longevity and overall vitality.
Supporting And Staking Full-Size Dahlias
Full-size dahlias, especially those with large flowers, often require additional support to prevent the branches and blossoms from drooping or breaking under their own weight.
Staking dahlias shortly after planting is recommended to ensure the plants receive the necessary support throughout their growing season.
Staking strategies for dahlias can involve individually staking and tying branches as they grow or using stakes on the corners of the dahlia beds and enclosing the plants with twine. Regardless of the method chosen, the goal is to provide the necessary support for tall dahlias, promoting strong and upright growth.
Different Staking Options For Dahlias
When it comes to choosing the right stakes for dahlias, there are various options to consider. Steel T-posts or 2″ square hardwood stakes are commonly suggested for providing sturdy and reliable support. These materials are robust enough to withstand the weight of the plant and the elements.
To ensure optimal support, stakes should be placed at 3 to 4-foot intervals throughout the dahlia bed. This prevents the sagging of the twine, which can lead to instability. The lowest row of twine should be positioned 12 to 18 inches off the ground, with additional twine added at 12-inch intervals as the plants grow taller.
Other staking options include wood stakes, bamboo poles, metal rebar, and tomato cages. Wood stakes, preferably 1½ inches in diameter and 6 feet tall, should be positioned 3 inches away from the center stem and pounded into the ground at least 12 inches deep. Bamboo poles can be placed on either side of the plant or in a square formation around the dahlia to provide support. Metal rebar is a durable option that can last for many seasons, with one stake per plant being sufficient.
Finally, tomato cages can be a practical option for supporting individual dahlias. Square cages that fold flat are ideal, and round cages can be modified by cutting off the legs and positioning them with the wide end resting on the soil surface.
By investing time and effort in staking and supporting your dahlias early in the growing season, you promote healthy plants with strong structures. Additionally, proper support makes deadheading and maintenance tasks easier, allowing you to enjoy the beauty and abundance of dahlias in your summer and autumn garden.

Frequently Asked Questions
Do dahlias need to be pinched?
Pinching dahlias is highly recommended for optimal growth and flower production. While dahlias can thrive without pinching, giving them a pinch will result in a more robust and compact plant with increased bloom yield. This advice holds true for all types of dahlias, whether they are border dahlias, dinnerplate dahlias, or decoratives. By simply pinching the plants, you can achieve a bushier and more fruitful dahlia garden.
Is it too late to pinch dahlias?
Pinching dahlias at the appropriate time is crucial for their healthy growth. It is recommended to pinch them when they are small, before they reach a height of 24 inches or have more than seven to nine sets of leaves. Pinching them later can be ineffective as their stems become hollow and hinder their response to pruning. Therefore, timing is key when it comes to pinching dahlias to ensure optimal results in their growth.
Do dahlias like to be wet or dry?
Dahlias thrive in soil that is kept evenly moist, without being overly saturated or dry. These large plants have a higher water requirement, so it is important to ensure that the soil retains moisture. However, the frequency of watering will depend on the soil type and climate conditions. In sandy soil, expect to water more frequently to maintain the desired moisture levels for dahlias.
How do I properly pinch dahlias to promote bushier growth?
To properly pinch dahlias for bushier growth, start by waiting for the dahlia plant to develop three to five sets of true leaves. At this stage, locate the topmost set of leaves and use clean gardening shears or your fingers to pinch off the entire top of the stem, just above the set of leaves. This process is called “pinching out” and helps stimulate the growth of lateral buds, encouraging the plant to branch out and become bushier. Additionally, make sure to remove any unwanted shoots or buds that can divert energy away from the main stem. Regularly pinching throughout the growing season will result in a more compact and fuller dahlia plant.
