I have a raised deck off the back of my house, that gets way too hot to enjoy in the summer. It is also very windy where I live, since it is in a river canyon. So, we have barely used the deck. We bought a pergola for the deck yesterday, which is going to be wonderful for keeping the sun off of the deck for part of the day, but I would love to add some trellis to the sides and grow Morning Glory on it, to use as a wind break and sun screen for the sides. I was thinking of building planter boxes, and was wondering if Morning Glory will grow good in them? Also, how deep do they need to be? I've grown Morning Glory for years, but it has always been in the ground, and I've never really paid any attention to how deep the roots are growing.
The ground on both sides of the deck is covered in brick pavers and rock, which looks like nice. I really don't want to remove them unless I have to. I was thinking that planter boxes would keep me from having to do that. But, I'm willing to do remove some of the brick and rocks if that is the best way to grow it.
Thanks for any help!
