shade tree in clay?
I live in zone 7a in Utah and I need to plant a tree for shade. The house has no permanent plantings yet, just my veggie garden. The tree will go in a southwest corner against the fence and hopefully shade a trampoline or sitting area under it. Our soil in this spot is clay. We have drip irrigation and sprinklers coming soon.
I would love a tree with these traits (in order of priority):
-does not drop anything spiky nor messy
-attractive to wildlife
-fast growing! we are in desperate need of shade!
-native/beneficial to the environment would be awesome
-no/little pruning necessary
-ok to walk over roots
Can you please give me some ideas of what trees I should consider? Temps are about 100 here now so I will probably keep it in a container until Fall and then plant it.
I love the gingko trees but it seems like it's a slow grower? I'm confused because some sites say it has moderate or medium growth rate.
Any comments/advice, please chip in!
