I put some garden soil in 2 buckets and filled it with rain water that I collected. I waited a few days but the water has not settled yet but I went ahead and dropped the seeds in. We'll see in a few days how the seeds are doing.
The soil I used is store bought garden soil. Online I saw some people just dug some soil out of their backyard. Unfortunately, my backyard is full of grass. If these seeds fail, on my next attempt, that is what I'll be doing.
