Last fall I had to remove a 25 + year old weeping willow tree we had in our front yard. We loved that tree for its shade on the front of the house and for its beauty. I removed the tree, stump and all the roots, which means I am going to be re-doing the entire front yard. My wife and I want to get a tree planted ASAP so it can start taking root and hopefully give us some amount of shade. We have shopped a few local nurseries/ growers. I think we have our choice nailed down to two, but we are both having trouble deciding. We have decided on either a Shamel ash (evergreen ash) or a Chinese Elm. We have narrowed it down to these based on their growth rate, the shade potential, lack of mess from fruit- flowers- berries-etc and the advice of local growers as to what is right for our location/climate. I will mention that we are in SoCal, so it is warm dry climate. Does anyone have experience with either of these two? We actually reserved a nice Shamel Ash today, but can change it before delivery. One thing we have seen online regarding the Ash tree is that the roots can be invasive and damaging. This really concerns us, but the nursery says it will not be a problem if watered properly. My other concern with the Ash is its potential size. We live on a city lot probably less than 10,000 sq ft. My location for either tree will be about 16-17' away from the eves on the front of the house.
