Have you upped your watering yet B? It looks really hot and dry there. How often do you get to water them? They could probably take 5 gallons apiece weekly if not more. I'm doin 4 gallons apiece weekly on mine, an i'm nowhere near as hot and dry as where you're at, and mine could probably take more still, especially through this heat wave we're havin. Although we did have a thunder & lightening storm move through on Saturday that brought some rain, and that's always a welcome thing in the middle of summer. When I got up to check my stuff there was mist rising from all the valleys. It was pretty sweet!!
I'll just throw these up here; sorry B!!
If you're haulin water any great distance, try usin a big backpack, or get some straps or something to carry your water across your shoulders. Use your back and shoulders and you can carry more water easier, especially over distance. I'm just sayin cause I see your 5 (?) gallon jug in your pics, and I know if your carrying that with your arms, my guess is it probably gets old really quick.
You know i'm not doggin' B, just a little advice learned from experience, and I like to share!!
Keep up the good work!!
