I didn't think we did, but after moving all of the plants on our terrace (which is on the 3rd floor), I put the number of plants we have at "a lot".
A friend helped me move them. His name is Wilson. And, of course, he was hardly ever even winded but graciously acted tired when I needed a break.
The best part was the two 30 gallon planters with some sort of evergreen and a eucalyptus tree.
Lesson learned: Put trees on the first floor.
Oh, and I forgot what sore meant. Why did this not hurt so much 10 years ago?
