I started moonflowers from seed in February, to be planted in containers with bamboo supports. One container with two seedlings is doing really well - the seedlings are getting leafy and green and climbing heavenwards. In the other pot, however, the seedlings look all chewed up and spotty and have holes in them, although they are still growing and climbing.

I've already uprooted the diseased-looking moonflower seedlings from the second pot. I have other healthy green (backup) seedlings that I could replace them with.

My question is, should I completely replace the soil that the other seedlings were growing in, before potting the backup moonflower vine seedlings in the "bad" pot? That's what baffles me about the two pots: I used the same potting medium for both.

Thanks,
