Managing Leggy Morning Glory and Moonflower Seedlings

Morning glory and moonflower seedlings in 3-inch peat pots are 3 weeks old, vigorous but yellowing bottom leaves, small new leaves. Fertilized with 5-1-1 a week ago. Too late? Nights 45°F, days 55°F—too cold to plant out?

Seedling Care and Timing

At first true leaves, transplant to individual cells/pots in regular potting soil. Dilute fertilizer 50%, feed weekly. Don't plant out until nights consistently above 45°F. Yellowing lower leaves = normal or slight nitrogen deficiency—weekly half-strength feed fixes it. Small new leaves may indicate root binding in peat pots or light limitation.
