I have the same problem, but I just planted the lantana about two weeks ago. My thoughts were that it was transplant shock. I got it an organic nursery: Texas Organic Nursery and Christmas Tree Farm located in Mexia. (I purchased it while visiting friends who live in Donie).

The leaves on my lantana seem to be doing all right. (The lantana to which I refer is the kind with yellow flowers). What time of day do you apply the Garrett Juice? When did you plant it? How much sun does it get?

Just occured to me that being our air & soil temps are so very hot right now, the plants may be suffering more than normal. It makes it more difficult for them to eat, as it does all of us. That would be my bet. I've moved my potted plants to where they get no more than morning sun right now and it helped a lot. The shade keeps the soil temp bearable and they do a lot better. The upshot here is that I suggest you try moving them to a place where they get shade half the day until our day & night temps go down a few degrees. The roots need a break!

Full sun is only for the most hardy plants right now. Everything else is just struggling through these "dog days"...except, strangely enough, my chives, which are growing like gangbusters and blooming too. They've been in the same pot for years and been through high heat and deep cold, so they're well established and I'm sure that helps.

reply: I planted the lantana in early June. You're right - i hardly get outside in August much less plant anything. But i will move them where they won't get the afternoon sun. The other pots with Candle tree, cannas, banana tree and sweetpotato vines are doing ok with the full sun, just have to water them each morning.

Why the heck are ya'll planting stuff in August anyway? It's too danged hot out there! (Says she who will be out planting a fall garden next weekend..... Just waiting for that little hint that the break is coming, don't ya know?
