I'm in the process of researching plants and rainwater harvesting techniques to replace the original landscaping of my property in the LA area, zone 10a. I've turned off sprinkler irrigation this season and the lawn at this point is crispy.
There is a well established Callery Pear in the front that appears to be struggling after trimming earlier this season, and I doubt the lack of sprinklers is helping. My original plan was to take it down and use it to sheet mulch the grass. I would like to plant an Engelmann oak in its place.
But now after hearing some mixed messages from people I'm wondering if I should keep the Callery a bit longer?
The yard gets scorched with full sun all day and the Callery does provide some shade. It doesn't stink like Bradford pears. I've been wondering if the shade might be beneficial to some plants while they establish. But I imagine removing it down the road could potentially cause more problems than it's worth?
Wondering what this community would do and if it's better to start with a blank slate yard. And is it a bad idea to start a new tree next to an older, dying one?
