Thanks folks. Yes the one in the bottom right of the third photo definitely got too much sun too fast when I put them out this spring but it is looking better now. I think I will change all my pots to clay and fresh soil and see what happens. When is the best time to fertilize? Just in the spring or throughout the summer? Is it too late now? our nights are starting to get fairly cool and soon they will have to be brought in for the winter.
