Do trumpet vines need any special care to make it through our cold Waupaca winters?
A. Trumpet vines are hardy to Zone 4 and need no special winter protection in your Zone 4 landscape. Increase winter survival of all plants by keeping them healthy during the growing season. Mulch the soil around the plants with shredded bark, evergreen needles or other organic material to conserve moisture, improve the soil and reduce weeds. Water the plant thoroughly as needed throughout the season and one last time before the ground freezes. Trumpet vines can be a little slow to leaf out in the spring. Remove dead tips and prune back established plants to control their size. Q.How should I overwinter my hibiscus? A. Let’s start by identifying the type of hibiscus you are growing. The tropical hibiscus (Hibiscus rosa-sinensis) need to move indoors for winter. Place in front of a bright sunny window and treat it like a houseplant. You just might be rewarded with flowers all winter. Or move the plant to a bright window in a cool room and water just often enough to keep the plant alive
