To begin, wait until the plant reaches eight to 12 inches. It’s not too late to pinch dahlias, but you should do it when the plant has four sets of leaves on its central stalk.

If you’re starting a new garden this year, it’s never too late to start planting dahlias. During the fall, you can divide dahlias and store them for next year. Dahlias thrive in Zone 7 and Zone 6 as long as the winters aren’t too harsh. You can also harvest them from their tubers. Jersey’s Beauty dahlia is a seven-foot-high plant with hand-size flowers.

You can plant your dahlia tubers in early spring or start them undercover in March. Plant them in shallow pots with a layer of compost. Cover them with a piece of fleece for one week before bringing them outside. Then, wait until the first shoots have appeared. They will continue to flower throughout the summer and into the fall. However, if you are planting in a row, you can use string or anchor posts to support the tubers.


The best time to pinch Dahlias is between the second and fourth sets of leaves when the plant is about 12 to 16 inches tall and has three or four sets of leaves on its stalk. If you are not sure when to pinch, you can use a thumbnail to gently pinch the stems off the plants. Pinching is most effective when the plant is at the base of its stems, but you can still pinch them off at higher levels if the plant is crowded.

You should wait until the stem is at least 12 inches tall with at least four sets of leaves.

Before planting, it is important to harden the tubers so that they do not get disease or rot. After digging up the tubers, cover them with fleece for one week and leave them in the garden during the day. Once the soil is warm enough, dahlias will send out new shoots in early summer. They may shoot early in spring, but that shouldn’t harm the plant in the long run.


If you want a taller flowering plant, you can begin by pinching the stems at the very tip of the stalk. This will encourage the plant to grow bushier. After it sprouts, you can continue to pinch the plant to encourage growth. Dahlias require moderate care, but they do not require staking. Sprouting dahlias takes time and patience. The tubers will grow quickly once sprouted.

Despite their compactness, dahlias need pruning after they bloom. This will prevent them from growing too wide and losing their compact shape. In order to properly pinch, you need to dig the plant’s tubers away from the stem.

Additionally, the flowers will be smaller and harder to see.


In late spring or early summer, it is safe to pull the tubers of Dahlias. Dahlias are prone to black spots, which can be prevented by spraying the tubers with a mixture of baking soda and water. During storage, dahlias don’t need light. Lift the tubers with the help of garden folk. If you find mold inside, cut the tuber off at an angle, leaving about 3/4 of it intact. This won’t have any effect on the plant’s growth.

Dahlia should be pruned when it reaches 12 inches in height with at least four leaves per stem. You should not pinch a dahlia that is much taller than this. However, if it reaches a height that is too tall, it will eventually fall over. If you can, support the stem with a stake or a sturdy stake for a few weeks before you cut it again.

During the summer, dahlias grow quickly, so it is essential to prune them at an early age. Pinching your dahlia at this age will encourage branching, which will result in more blooms later in the season. In general, dahlias are best pinched when they are about 18 inches tall.

Pinching dahlias is an important part of the process and should only be done if the tubers have rotted. Dahlias are considered tender perennials, so they can stay in the ground over the winter in zones eight to ten. In zones colder than zone eight, dahlia tubers should be stored indoors to prevent rotting. Use a USDA Hardiness Zone Finder to determine which zone your dahlias belong in. This tool will show you the minimum winter temperature for your area. Zones are given in degrees Fahrenheit.

Soil preparation is an essential part of the planting process. Begin by preparing the soil by weeding and fortifying the soil with compost or fertilizer. You can also add soil amendments to improve the soil’s pH. A good soil pH range is between 6.5 and 7.0. You can find a soil test kit at your local hardware store or Luster Leaf. Once you’ve added soil amendments, check the pH level of your bed. If the soil is too acidic, you can add agricultural lime to balance it out.

If you’ve neglected to pinch dahlias, you should consider deadheading instead. Deadheading encourages new blooms while reducing the amount of energy directed to making seeds. Alternatively, you can use a sharp knife to cut off a dead flower head. Regardless of the method, it’s better to remove the spent flower head before it sets seed.

If you’ve planted dahlias in the ground, make sure you dig them deep enough to protect them from damage. If you have a pine forest, consider spreading pine straw over your dahlia patch.
