clematis - how/when to move young plants from indoors to outdoors

terryo2March 9, 2014

I have 2 young clematis plants (Dr. Ruppel & Sweet Summer Love) that I received in US mail in 4" pots. I transplanted them to larger (maybe 8" diameter pots) in a sunny unheated room (zone 6b).

They were in very bad shape but now are growing well - 'Dr. Ruppel' just had a bloom. SS Love has grown to about 4 feet tall.

How and when do I move them out onto my balcony which is pretty sunny but very exposed to wind and weather?

Should they be growing indoors like this?

I just don't know what the next step is. Any help greatly appreciated.

Move them outside when you don't have any more frosts or freezing temps. You must let them get used to being outside, you need to acclimate them. Bring them out for one hour the first day and increase time for 2 weeks, then they will be fine. You could grow them indoors if they are doing OK, it's up to you. You need also to slowly expose to the sun. The first few days I would leave in the shade, slowly increasing sun exposure daily too. By the last day 8 hours outside and in the sun or whatever your exposrure is. They do need sun.. 14 days is about right, works best for me.

I keep mine in the garden, one is about 25 years old. I added four more last year. The 25 year old one is massive, I cut it completely down every year. It grows like crazy and produces hundreds of flowers. Pruning depends on what type you have. 3 groups exist, each are pruned differently.
Brushwood Nursery has a good grow guide for Clematis
