Dear gardeners,
I have a north facing garden which gets a lot of ambient light but only a few hours of direct sunlight. I am struggling to see good results with:

1. Zepherine Drouhin climbing rose - Planted this last spring and it grew a few branches that I have trained on a trellis. The branches are very thin though and I had to remove a bunch of leaves on them because of mildew.
2. Rangoon creeper or honeysuckle - Planted this last spring and saw some growth, but completely shed all its leaves during the winter. Also the main growth was a single vine with tiny branches off of it.

My question is if I can place these plants in a sunnier location (friend's place) during the growing season to trigger good growth and bring them back to the shade later on. I am hoping that a more mature plant with thicker branches and more leaves can tolerate less light more effectively. Do you think it will work?

Both are full sun to part shade plants that require about 6 plus hours of direct sun. What you want to do would get you larger plants in the short term providing they survive the transplants but in the long run does not sound like the right growing conditions.
