I hear ya
I try different things, too -- but I also like to plant in the ground to see what the difference in potential is, and at least in my case, the containers tend to stunt.
I am counting down the days I can plant in the ground! We moved back in with my parents to help start a family business and just as I'm living out of boxes, my poor plants are, as well.
One day, we shall all be free! I also feel for all of those in drought areas. I turned down a high paying job in SF because I'd have to give up my garden. All my plants are currently on a screen pool deck, but under the second floor patio. So they get a lot of eastern light, then get a break the rest of the day. Florida sun is so brutal. Even my sun loving plants are like "give us a break already!" I used to have a pretty great drip irrigation set up, but I'm making best with the situation right now. Our rain is so sporadic and intense when we get it. Hope your plants keep getting plenty big!
One thing that does keep my plants growing, unbelievably so, is a discontinued plant food. When I ran out, I called the company because I couldn't find anyone carrying it, and they said it was discontinued, but sent me four bags complimentary because I was so in love with it. Now I want to break down the ingredients and make my own. It seems to have superhero strength steroids in it. I can see higher yield and next day growth spikes every time. The stuff is magic. I wonder why they discontinued it.
