If you want to save and store your begonia bulbs over the winter months, treat them with a sprinkle of dusting sulfur to discourage mold, cover them and leave them in a cool place. Get all the details in this free video on growing and storing plant bulbs.
I'm Donna Emery from Glover Nursery in West Jordan, Utah. We're going to talk about saving Begonia bulbs over the Wintertime. You can buy Tuberous Begonias either as starts, like these bulbs are actually a tuber, or you can buy them already planted in the Spring like these are. If you want to try and keep them until next year, you have a couple of options. One, is you can dig the bulbs out of your garden like this. This actually has a shoot. You could break that off and then nestle it in some bark or sawdust or sand that is slightly damp but not wet. Now, before I do that I like to give them a little shake of dusting sulfur so that it helps retard the disease growth and mold growth, nestle them into this material, cover them lightly and put them in a cool but not freezing place. The garage is fine if it doesn't freeze or your basement. In the Spring, you lift them out of this. You can soak them for an hour or two in just plain warm water and then plant them in your garden again after all danger of frost has passed. Now during the Winter, while they are sleeping, check on them a couple of times. The media that they're in should be damp but not wet. The tubers themselves should not be shriveled and dry nor should they be moldy. If it's moldly, it's too wet, they're shriveled and dry. You need to just lightly mist this bark dust with some water and come Spring you should be able to lift them out and replant them and have beautiful Begonias again.
