I direct seeded kale in a raised bed, it started growing well but now the seedlings are dying one by one. I don't think it would be lack of water because the tatsoi that is in the same bed is thriving. There are rabbits around but I don't think it is them because I can see the shriveled leaves still intact on the kale plants. There are ants that are making ant hills around the stalks of the plants, this I have never seen before. Thanks for your help!
