My Dapladenia is outside in the ground. How do I protect it from outside weather?

Growing zone 7 or below, you should bring your Dipladenia indoors to overwinter.
Zone 7 or above you can spread 3 inches of mulch or straw around the roots. Water only when the soil becomes dry and do not fertilize in the winter.
Depending on the region you are in, you are either zone 6b or 7b. If the temperatures in your garden are below 45 degrees F., the plant should be brought indoors.
