Welcome Back Ogrefugee, it is an honor to post in your thread. In this journey of life good karma and positive energy really do bring good things full circle.
Red clay soil, you wanna do it good haul your own in. Mix the native soil back in at 30%. Drought most summers, gonna have to make use of that water if you can. Always wanted to run lines myself, but carrying with my back is how it gets done. Watch for the flash floods we get when it rains for a day or three after being dry for a month or three. Then it likes to get wet end of Sept beginning of Oct to mold up whatever has made it thus far.
Sun needs to hit them soon as it comes up so it drys off the Morning Dew, then you want full sun all day as much as you can. Southern exposure
Keep the numbers down and start with a few BIG holes. 50gal/100gal . Amend every year and dig more as you feel you can take care of them. Even just one well taken care of plant in a big hole will usually out produce 10/15 smaller plants that cannot be taken care of properly.
My experiences anyhow, hope it helps pics from 2yrs ag
