Dahlias are a popular flower for home gardeners, and for good reason. These easy-to-grow plants bloom in the summer months and come in a wide variety of colors, shapes, and sizes. Dahlia tubers can be stored over winter to extend your growing season, but storing them properly is key to ensuring that you get healthy new plants from them next spring.
However, if you live in a climate where the weather is colder, storing dahlia tubers is necessary to ensure they will bloom again when you want them to. This article will teach you how to store dahlia tubers correctly so they will last until next year’s planting season.
When to dig up dahlias?
There are a lot of reasons to dig up your dahlias, but if you’re in zones 7 or colder, you’ll want to do it before the first hard frost strikes. When the plant turns yellow and dies back, it’s a good indication that the time is near, usually around late fall.
The best time to dig up your dahlia tubers is when the flowers and leaves of your dahlias go brown and wither (usually at the end of Autumn). The reason for this is that once they have gone dormant, they will be able to store energy for next year’s blooming season.
There’s nothing worse than seeing a beautiful plant wither away in your garden because you didn’t realize how quickly the winter months were approaching. If you don’t have time to dig them up yourself, consider hiring a professional gardener to do it for you.
How To Remove Dahlia Tubers from Plant
Once frost has killed the plant, you can remove the tubers. The best time to do this is after the first frost, as this will kill any insects that may be on the tuber and prevent it from rotting. The key thing to look for when harvesting dahlia tubers is whether they are firm or soft or mushy. If they are firm, they are ready to be dug up; if they are soft or mushy, wait until next year before removing them from your garden bed.
To dig out your dahlia tubers, use a trowel or sharp knife at the soil level in order to gently lift them out of their beds. You can also use a fork to loosen the soil around each tuber so that it comes free more easily once you have exposed it with your digging tool (this method works best if there are several plants growing close together).
Preparing Tubers for Storage
First, remove any damaged or diseased tubers. Next, remove any stems and foliage that are still attached to the tubers. Wash them thoroughly with a garden hose before storing them in a cool, dry place such as an open bin or box on a shelf in your garage or basement.
Dig up dahlia bulbs in the fall.
In early fall, dig up dahlia bulbs. The best time to do this is in early fall because you will be able to see what color the flowers will be when you plant them next year. If you leave the tubers in the ground too long, they may start to rot and won’t look as nice when they flower again.
Clean the dahlias and trim back the plants.
Clean the dahlias. The purpose of this step is to remove any dead flowers and leaves that are yellow or brown. You can also cut off damaged leaves, small leaves, or oversized ones (if they’re too large).
Trim back the plants. This helps them withstand transportation better, as well as storing them in a container where there’s less soil around the roots.
Don’t drop the tubers. This is a good rule for everyone to follow in life, but especially for dahlia growers who are about to store their tubers. Avoid dropping them on the ground or floor. Your dahlia tuber should be kept clean and dry from the moment it’s removed from the soil until it’s planted again in the springtime. If you can manage this with minimal bruising, you’ll have healthier plants come next year.
Allow the bulbs to dry for a few days.
After you have planted your dahlia bulbs, allow them to dry for a few days. This is important because it will prevent the bulbs from rotting and also helps them store better. When stored properly, dahlias can last for years if not decades in cool storage conditions. The drying process also allows you to store your bulbs in smaller spaces than normal.
Check roots for signs of rot, disease, or pests.
Next, check the roots for signs of rot, disease, or pests. Rot can be identified by an obvious discoloration of the root. If you see any signs of rot, discard that tuber and do not plant it again.
The disease can be identified by a black or brown spot on the tuber’s skin or fleshy interior tissue below the skin (the eyes). If you see any spots that look like this, discard that tuber and do not plant it again. Pests include slugs and snails that will eat holes into your tubers before they mature into flowers.
Remove excess soil from roots with a stiff brush (a toothbrush works well). Brush off excess soil from roots with a stiff brush. I use a toothbrush, but you can use any stiff-bristled brush that you have on hand.
Place the dried dahlia bulbs in a mesh bag or paper bag.
Now that the dahlia bulbs have been allowed to dry out, you can store them in a paper bag or mesh bag. You want to keep the bulbs clean and dry, so keep them away from moisture. Also, if you’re storing your dahlia bulbs in a paper bag, make sure not to crush them—they can easily break. If you’re storing your dahlias on display (such as at a flower shop), consider using an opaque plastic bag instead of clear plastic or glass containers because they will be easier for customers to see through without getting distracted by what’s inside the container itself.
Store the dahlia bulbs in a cool, dark place that maintains a temperature between 40 and 50 degrees Fahrenheit. The ideal humidity level for most bulbs is about 30 percent. To ensure proper storage conditions, keep your dahlia bulbs out of direct sunlight and store them in a mesh bag or paper bag. Check on the bulbs every two to three months and discard any soft or shriveled ones so they won’t rot and infect their neighbors during storage.
Check on the dahlias every 2 to 3 months. Discard any soft or shriveled bulbs. Dahlia bulbs can be stored in mesh bags or paper bags. Store them in a cool, dark place that maintains a temperature between 40 and 50 degrees Fahrenheit.
One of the most important things to know about dahlias is how to store them correctly. You can store them in almost any container, but you will want to make sure that the container has holes in it so that air can flow through it. This will make sure that mold does not form on your bulbs when they are stored over long periods of time. You also want to make sure that your container is not too large for your bulbs or else they will be crushed under the weight of other objects inside.
Ways of Storing Dahlia Tubers
Dahlia tubers can be stored in a number of different ways, but the best option depends on how long you want to keep them.
-If you’re looking for short-term storage, you can simply leave your dahlia tubers in the ground and cover them with mulch. This will keep them from freezing and will help protect them from pests.
-If you’re looking for medium-term storage, try storing your tubers in a box or bag with peat moss or sawdust. The moisture from the peat moss or sawdust will keep your tubers from drying out, and the darkness will help prevent mold growth.
-For long-term storage, it’s best to store your tubers in a cool place that is dark and dry, such as a cellar or garage, and allow them to dry slowly over time before planting them again next spring.
Maintaining Stored Tuber Temperature and Moisture
Temperature and moisture are important in preserving dahlia tubers. If either of these is incorrect, rot may occur. The optimum temperature range for storing your dahlia tubers is between 40 to 50 degrees Fahrenheit (5-10 degrees Celsius). If the temperature is too low, the tuber may freeze and die; if it’s too warm, it will begin to sprout prematurely. The optimal relative humidity for storing dahlias should be about 60 percent; if it drops below 50%, water loss through evaporation will be greater than you’d like when you finally put your plants back into the soil.
To monitor temperature and humidity levels in your storage area, use an indoor/outdoor thermometer with a probe that can be placed on the floor near where you’re storing your tubers (or just take a regular old thermometer along with you when you go shopping). You’ll also want to test the soil’s moisture level by digging down about 6 inches deep into one corner of your bin or box and using a trowel or spade; look at how much moisture there is there before deciding whether or not any additional watering might be necessary during this time period (this method won’t work so well if you’re storing them outside).
Tips for Producing Healthy Dahlia Plants Next Season
The dahlia is a beautiful flower that produces vibrant colors and intricate patterns, which makes it a popular choice among gardeners. Dahlias can be grown in a variety of climates, but they require some special attention to produce healthy plants for the following season. Here are some tips for producing healthy dahlia plants next season:
1. Dahlias need full sun exposure and well-drained soil. They have large root systems that grow deep into the ground, so your garden beds should be at least 12 inches deep with good drainage.
2. Dahlias prefer temperatures between 65 and 80 degrees Fahrenheit during the day and 55 to 70 degrees at night. If you live in an area where temperatures dip below 60 degrees at night, bring your plants indoors until spring arrives (or plant them outside earlier).
3. Dahlias need moisture throughout the season, but too much water will cause rot or mold problems on the leaves and buds of your plant; check your soil daily to make sure it doesn’t dry out completely between watering sessions.
4. Keep an eye out for aphids and other insects; they are attracted to dahlia flowers because they contain nectar from which these pests can feed themselves and their young offspring.
5. Fertilizing Dahlias is also important because it helps them produce bigger blooms with more color than if they weren’t fertilized at all. You should apply fertilizer once per month during their growing season (which lasts from June until October), but never use more than two pounds per 100 square feet per application because too much fertilizer can damage the plants.
6. You should also keep an eye out for yellowing leaves and wilting stems, which are signs that your dahlias need more water. If you see these symptoms, you should immediately give them a thorough watering session so they stay healthy and happy.
These tips will help you keep your dahlia tubers in good condition for the next growing season.
We hope that we’ve given you some insight into how to store dahlia tubers so they can produce healthy plants next season. We also hope that we’ve helped you avoid some common pitfalls, such as preventing rot or mold from taking over your stored tubers. It takes a bit of planning and organization in order to keep things running smoothly, but with these tips in mind, anyone can do it.
