How to over winter new clems?

19 years ago

Hi, I usually am over on the Cottage Forum and am branching out, so to speak. I got 3 new clems in 4" pots from Blue Stone. I potted them right away in 1 gal pots. They are doing very well and growing very well. I always have great luck with clems but usually buy the "Big Box" large ones. What do I do come winter with these potted 1 st year ones? Thank you for your help. Caroline

Caroline, in your zone, you can just let the pots sit outside in a sheltered spot. To prevent premature growth, I would put them out on the north side of the house since that will help keep them on the cooler side of the house. Another option I have used in zone 7a NC is to dig a hole in well drained area and then just sink the pots into the hole. The warmth of the soil will allow root development far into the winter and give you bigger roots for the spring. Just remember that dormant clematis will need some water if you store them in an area where the eaves of the house may shelter them from any rainfall you do get.

I lost potted 'Vienetta' this winter. It seems to be a tender variety. All my other potted Clematis (30+) survived with some minor protection very harsh winter that we had this year (I am in zone 6/7, MD).

Thank you for the advice. I love the clems I already have and they seem to love me ! I have a walled garden with a swimming pool and the micro climate seems to be just what they like. I will get them in the ground in the spring. I love this forum and have listed the suppliers that you all have suggested. I can hardly wait to get some gal. sized ones . Thanks again, Caroline

I don't do anything special to mine and I am in Zone 8 too though my zone 8 is a lot cloudier and has less hot days than yours.

'Vienetta' is a florida cultivar which would make it less frost hardy than most.

Clematis florida species are alot hardier than was originally believed. I know of several people in the Michigan area who successfully grow Clematis Sieboldii outside in the ground. Most books give recommendations as to it only being hardy to zones 7 to 9 (the Toomey and Leeds Encyclopedia for one!), but the experience of people in Michigan zone 5 shows that the true hardiness ratings is not known with any certainty. That is why the international survey Clematis on the Web is conducting on hardiness and overall growth characteristics of all clematis is such a great thing that everyone growing clematis should participate in.
