The foliage on the Ipomoea leptophylla seedlings I started some time ago has gradually turned yellow, and eventually dried up on 3 out of the 4 seedlings that were previously growing well. The last seedling is getting yellowish now too. I don't believe it's overwatering, as they are in a fast-draining mix, and have been watered on the same schedule as other alpine seedlings. I knocked the soil out of the one of the pots and found a large, healthy-looking white root. Is this some sort of dormancy behavior?
Tim, or anyone else, have you see this with seedlings of this species? Thanks in advance for any info.
