Hello guys, I recently bought two Chilean mesquites 15Gal about 3 weeks ago. One seems to be doing well while the other has dried up leaves that are all coming off. I dug and planted in wide and deep hole mixed miracle organic soil with semi clay like native soil. I have been watering a few times per week and we have recently had some thunderstorms. What could be going on with my Chilean? I don't want to loose it. I paid around 55$ please help with any suggestions. Thank you much!
