Dormant bulbs, corms, and tubers are a great way to ensure that certain plants can survive through the winter. These tender perennials have underground storage structures that allow them to go dormant during the colder months, protecting them from the harsh conditions.
One example of a plant with a bulb is the canna. Cannas are known for their vibrant flowers and lush foliage. In colder climates, it’s important to dig up the bulbs before the first frost. Once the foliage has been killed by frost, it’s time to prune the canna back. This helps to prepare the plant for dormancy and makes it easier to store indoors.
Gladiolus is another tender perennial that can survive winter with the help of its corms. Corms are similar to bulbs but have a solid texture rather than layers. When the gladiolus foliage turns yellow or brown, it’s a sign that the corms are entering dormancy. At this point, the foliage can be pruned back and the corms can be dug up. It’s important to remove any excess soil and allow the corms to dry thoroughly before storing them.
Dahlias are also tender perennials that can be saved over the winter by digging up the tubers. Tubers are thickened underground stems that store nutrients for the plant. Once the foliage of the dahlia has been killed by frost, it can be pruned back and the tubers can be dug up. It’s important to handle the tubers carefully to avoid damaging them. After digging them up, they should be allowed to dry and then stored in a cool, dark place for the winter.
Storing these dormant bulbs, corms, and tubers is relatively easy. They can be placed in paper bags or cardboard boxes with some dry peat moss or vermiculite to help absorb moisture and provide insulation. It’s important to check on them periodically during the winter to make sure they are not rotting or drying out.
In my own experience, I have successfully stored canna bulbs and gladiolus corms over the winter. I dug them up in the fall, pruned back the foliage, and allowed them to dry before placing them in a cool, dark area. Come spring, I replanted them in the garden and enjoyed their beautiful blooms once again.
By taking the time to dig up and store these tender perennials, you can ensure their survival through the winter and enjoy their beauty for years to come.
