Fall is Upon Us

Fall Leaves and Clematis Seedheads

Here is what I do in fall (or at least try to most of time) to keep my babies happy!  I have adapted this things to-do list to accommodate gardeners in the other parts of the country. 

Whack Down Those Weeds

Clean up and remove weeds that can harbor diseases and pests.  

The Final Meal

Give your clematis one last feeding before winter comes.  In USDA Zones 4-9, do a final feeding for clematis with Gro Power 3-11-11 in early September or 6 weeks before the first frost.  In USDA Zones 10 & 11, do a final feeding for clematis with Gro Power 3-11-11 between the end of September and early October.  This will tide them over until they are ready to come to life in spring.

Tuck Your Clematis Under a Nice Cozy Blanket of Mulch

Reapply mulch on your garden beds before your clematis take their winter nap.

Time to Prune?

Yes, if you live in USDA Zones 10 & 11 prune your clematis in November. In USDA Zones 4-9 you will wait until February or March. After pruning, to help prevent any stem rot or fungus, apply a Physan 20 drench to soak the plant and planting site.

Nuke Responsibly Any Potential Overwintering Scoundrels

To help eradicate any overwintering insects, spray your clematis with a natural pesticide made with an ingredient such as pyrethrum or with horticultural oil which will suffocate them.

Prepare for Winter

Where the ground freezes, prepare for winterization.  Continue to water throughout fall. Protect garden clematis plants from light freezes by covering them with blankets, sheets, cardboard or baskets. (for more information see: Winterizing Your Clematis)
