Thornless Hybrid Mesquite - Planting Hole depth
Hello Forum, As posted yesterday, I'm excited about planting a South American Hybrid Mesquite "Chilean" in my backyard to provide some MUCH needed shade for my patio.
Yesterday afternoon I dug a planting hole per the instructions given to me at the nursery. The hole is about two feet deep (for starters). To test the drainage, I filled the hole about half way with water. This morning the water is pretty much in exactly the same spot! In other words, it hasn't soaked in or absorbed at all! I'm thinking this is indicative of poor drainage. My question, how much deeper do I need to dig? If there is a caliche or layer of clay, how deep might I need to go to bust through it? Can mesquite roots bust through it? Some of my neighbors have really tall trees (originally planted by the home builder) and I'm assuming their backyards have the same drainage issues that mine does. Again, Thanks for all your help.
