Storing Dahlia Tubers: Tips to Keep Your Flowers Blooming Year After Year

If you're an avid gardener, chances are you have a soft spot for dahlias. These showy flowers come in a variety of shapes and sizes, and their bold colors can brighten up any garden bed or container. But as the growing season comes to a close, it's important to properly store your dahlia tubers so they can bloom again next year. In this article, we'll go over some tips and tricks to help you successfully store your dahlia tubers.

Choosing the Right Time to Dig Up Your Dahlia Tubers

The first step in storing your dahlia tubers is knowing when to dig them up. Wait until the foliage has turned yellow or brown and has died back to the ground. This usually happens after the first frost of the season. If you live in an area with mild winters, you may be able to leave your dahlias in the ground all year round. However, if you're expecting a hard freeze, it's best to dig up your tubers and store them indoors.

Preparing Your Dahlia Tubers for Storage

Once you've dug up your dahlia tubers, remove any excess soil from the roots. Then, use a sharp knife or pruning shears to cut off the stems about 6 inches above the tubers. Be careful not to damage the tubers themselves. Next, let the tubers dry out for a few days in a warm, dry place. You can also dust them with a fungicide powder to prevent rot during storage.

Choosing the Right Container for Storing Your Dahlia Tubers

When it comes to storing your dahlia tubers, choosing the right container is crucial. You want a container that is big enough to hold all your tubers without crowding them, but not so big that the tubers move around too much. A cardboard box lined with newspaper or a plastic bin with drainage holes can both work well. Just make sure the container is clean and has good ventilation.

Storing Your Dahlia Tubers in the Right Conditions

Once you've selected your container, it's time to add your dahlia tubers. Place them in a single layer on top of some damp peat moss or sawdust. Make sure the tubers aren't touching each other, as this can cause them to rot. Cover the tubers with more peat moss or sawdust until they are completely buried. Store the container in a cool, dark place with a temperature between 40°F and 50°F, such as a basement or garage. Check on the tubers every few weeks to make sure they're not drying out or rotting.

Tips for Successfully Storing Your Dahlia Tubers

Here are a few additional tips to help you successfully store your dahlia tubers:

• Label your container with the type of dahlia and the date you stored it, so you know which tubers to plant next year.
• Avoid storing your tubers near fruits and vegetables, as the ethylene gas they produce can cause the tubers to sprout prematurely.
• If you notice any signs of mold or rot on your tubers, remove them immediately to prevent the problem from spreading.
