Canna Lily, Elephant Ear and Gladiolas are examples of plants you can overwinter. Since we have had a couple of good frosts here in the Miami Valley, it is time to prepare our tubers, roots and corms for winter storage. These types of plants can have problems surviving a deep freeze.
Now is a good time to divide these plants. You can break them apart with your hands or use a sharp butcher knife to make clean cuts. Keep one to three starts in each clump, depending on their size. There are a couple of different ways to prepare these plants for winter storage: dried or in containers.
Beginning in mid- April, when temperatures are mild, you can put the plants outside. Remember to protect them from being exposed to a hard freeze.
Another group of bulbs that needs winter storage are the spring blooming ones. These are best protected by a blanket of soil that will stay cold over the winter – in other words, planted in the ground. There is still time to get them put in before the ground freezes.
By spending a little time now, you can enjoy a jump on next season with plants you grew. Then concentrate your spring purchases on new varieties!
