We are buying a new home that is almost complete. They have already done the landscaping and planted two hibiscus trees in the ground. We want to extend the patio into the space where the trees are and put the trees in pots. The landscaper said that wouldn't be a problem. I asked what size pot he'd recommend and he hesitated, stared at the tree for a bit, and then said two 30" pots should so it. I have zero experience with hibiscus trees, but after reading on the internet, I am thinking 30" is way too big. Am I wrong? These will be outdoors in FL year round. Is 30" overkill? The trees are about 3 feet tall now. If we do need 30" any clue where we can buy them? I've yet to find any that big. Thanks!
