Clematis "planters" around deck - a few questions
Put this on the clematis forum, but it's gotten no responses. DH wants to start building the deck!
We are installing a deck on the back wall of our garage, and we intend to leave square(ish) gaps (cut-outs) in the decking so that we can plant clematis to grow along the wall of the deck. It will be a mix of Huldine and something else, perhaps Jackmanii since it's so reliable. We don't have a sketch of this yet, but here is the idea:
-About 2' between each cut-out space for the clematis.
-Thinking that the cut-outs need to be about 10"x10". What do you think? Bigger? Smaller?
-There's going to be a space of about 10" between the top of the deck and the ground below. Do you think a square column (same width) would be sufficient to hold the root system for that far? Or would you build larger boxes , even though the cut-outs may be smaller?
-What about the idea of getting plastic planter pots, with the bottom removed, to hold the roots in the 10" gap beneath every cut-out? How big would you make those?
Any other thoughts or ideas about this? Thanks for any help!
Edited to add:
Well, my DH modified his CAD drawing of the deck to include the built-in gaps for planters. Those are the spaces here that are mostly "ringed" at the bottom.
So the questions are:
a) Are these holes big enough? (10"x9")
b) How would you recommend bridging the gap between the decking and the ground 10" below?
