Okay, so ive planted a total of about 16 plants over the course of the last 4 weeks... and I have two left. I am pretty sure its the storms and heavy rains TN's been getting, but Im not 100% positive. I'm not sure if it matters but, I looked around my plants and there seemed to be a good deal of roley poleys in my soil and fire ants in the vicinity of my plants. The plants keep dying when they're about 1 week - 1.5 weeks old. I actually dug around in a few of the dead plants' soils and I find the roots of the plant, but no top half (the part that sticks above ground with the leaves) I havent seen my plants in 4 days, so i will be going back today and i will have news if I have any plants left. So... I ask you, What is happening to my plants and how can I prevent it? Or is it just one of the setbacks of outdoor?
