I swear I have a black thumb. Any plant I care for dies.I plant herbs in window boxes, water them daily, they wither and die. Same for herbs in pots. I even set up a growlight in my kitchen, and they all just died.I transplant something, it dies. I got fancy soil to try to make my African violet bloom, now it's mostly dead.If I try gardening outdoors, the weeds take over. We have a raised garden bed that is currently full of 10'+ tall giant ragweed. I have a front flower bed with a couple roses, some beebalm, and WEEDS. Nothing else will take.Help??
