>>2136693Sorry to hear that, anon. Mine are in clay as well and at a flooding area to boot. I dug holes a couple feet deep, surrounded them with concrete blocks, and filled them with a compost mix. Hopefully that overcomes the bad location.
Its probably not too late to plant more. You could also try a wicking tub like included pic. Gardening with Leon YT channel has some good walkthroughs on how to make them.
