I believe the diagnoses of the three leaf seedling is called a "whorled phyllotaxy" which is a kind of genetic anomaly, but it's nothing to worry about. I think it'll grow out of it, but if not, it should still grow normally. As for the stretched seedling, it could be a number of things. Temperature variations and nutrient deficiencies can cause a seedling to stretch, as well as low levels of light. Are the leggy seedlings under direct sunlight? Or are they slightly shaded throughout the day?
Mr. Clandestine Reviewed by Mr. Clandestine on . Seedlings! Awwww. Heya. I got a few questions. I have 4 brand new, outdoor-grown (florida), seedlings. I have 2 questions about them. 1) 2 of the seedlings grew like 3 inches tall before the true leaves appeared, even though they were all planted 1 1/4 inch deep. Any reason for this? Is it the strain of plant? 2) One of the seedlings is growing normally, but its true leaves grew in a set of 3, rather than 2. So there are 3 jagged leaves growing above the 2 seedling round leaves. Why is this? Rating: 5
