Dahlias are one of the most beautiful and versatile flowers you can grow in your garden. They come in a wide range of colors and sizes, making them perfect for any occasion. However, knowing when to harvest them is crucial to preserving their beauty and longevity.

In this article, we will discuss the optimal time and technique for harvesting dahlia plants.

Optimal Time for Harvesting Dahlia Plants

Dahlias bloom from mid-summer until the first frost. The best time to harvest dahlias is when they are fully matured, which is usually in the late summer or early fall. At this time, the flowers are at their peak and have reached their full size and color.

One way to tell if your dahlias are ready for harvesting is by examining their petals. If the petals are fully open and firm to the touch, then they are ready for picking. If the petals are still tightly closed or soft to the touch, then it’s best to wait a few more days before harvesting.

Dahlia Plant Harvesting Technique

Harvesting dahlia plants properly is important to ensure that they remain fresh and beautiful for as long as possible. Here are some steps to follow when harvesting your dahlias:

  1. Use sharp scissors or garden shears to cut the stem about 6 inches below the flower head.
  2. Cut the stem at a 45-degree angle to prevent water from pooling on top of the cut.
  3. Remove any leaves or buds from the stem that will be below the water line in your vase.
  4. Place the cut flower immediately in a bucket of water.

It’s important to harvest your dahlias early in the morning when they are still cool and well hydrated. This will ensure that they last longer once placed in water.

FAQ

How long do dahlias last once harvested?

With proper care, dahlias can last up to a week once harvested. It’s important to change the water in the vase every two to three days and trim the stems at a 45-degree angle each time.

What should I do if my dahlias wilt after harvesting?

If your dahlias wilt after harvesting, you can revive them by submerging the entire flower head in water for a few hours. This will allow the flowers to rehydrate and regain their strength.

Can I harvest dahlias before they are fully bloomed?

It’s best to wait until dahlias are fully bloomed before harvesting them. This ensures that they have reached their full size and color, and will last longer once placed in water.

How many times can I harvest dahlias in a season?

Dahlias can be harvested multiple times throughout the growing season, from mid-summer until the first frost. It’s important to leave enough flowers on the plant so that it can continue to grow and produce more blooms.

In conclusion, harvesting dahlias at the optimal time and using the correct technique is crucial to preserving their beauty and longevity. With these tips, your dahlias will last longer and add stunning color to any space.
