How Can I Keep Purple Foxgloves During The Winter?

Q: I have two purple foxglove’s. How do I overwinter them in their pots? They can’t go inside the house as we have pets. 

A: The easiest way is to sink each pot in a hole of appropriate width that is a few inches deeper than the pot. Place gravel or a brick in the bottom to raise the pot off the soil. This will prevent the roots from being in standing water if we get lots of rain. Hardy plants do much better outdoors in winter rather than in front of a sunny window or in your basement.
