Preparing to Plant Moonflower Seeds
Moonflower seeds need careful preparation in order to ensure beautiful white night blooms on flowering vines in your garden. The seeds should be prepared for germination four to six weeks before the final springtime frost in your area.
Open and Hydrate Seeds
With a sharp knife, make a small cut in each seed. Put the seeds in a small glass dish and cover them with water. Leave them to soak overnight.
Plant the Seeds
Fill two-inch deep peat pots with a soil-free potting material, to 3/4 inch from the rim of the pot. Dampen the potting material well with water, and set three santana moonflower vine seeds on top. Add another 1/2 inch of the soil-free potting material, and water sparingly. Keep the planted pots in a moist, warm area until the seedlings are sufficiently large for transplanting.
Cull the Seedlings Before Transplanting
The moonflower vine seedlings will germinate in about 3 weeks. Once seedlings have formed 2 or 3 leaves, they are ready to be transplanted outdoors. Check each pot, and cull the seedlings back to one per pot. Cut back the weaker seedlings carefully with scissors. Pulling them out by the roots will cause damage to the remaining one.
