How to Sow
Sowing Directly in the Garden:
- Moonflower seed has a hard seed coat. To aid germination, nick or cut the seed coat with a nail file and soak the seed overnight.
- Direct sow seeds in average soil in full sun two weeks after danger of frost has passed. Moonflower is a vigorous vine; choose a location next to a support for the vines to climb.
- Moonflower is not generally recommended for containers.
- Prepare the soil by removing weeds and working organic matter into the top 6-8 inches of soil; then level and smooth. Moonflower tends to prefer poor soils rather than highly enriched soil.
- Sow seeds thinly and cover with 1/2 inch of soil.
- Firm soil lightly and keep evenly moist.
- Seedlings will emerge in 7-14 days.
- Keep soil evenly moist but not wet.
- Thin to stand 12 inches apart when plants are 1 to 2 inches high.
- Do not fertilize unless the plants are showing a nutrient deficiently. Over fertilizing may produce lush green vines with few flowers.
- Monitor for pests and diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.
- Remove plants after they are killed by heavy frost in fall to avoid disease issues the following year.
- Moonflower vines need little care and are easy to grow.
- Plants can self-sow so allow some to set seeds at the end of the season if you would like it to come back next year. If you would like to prevent self-sowing, remove seed pods before the seeds are released.
- When night falls flowers open quickly, sometimes in less than a minute. Excellent plant for a patio where you may enjoy the summer evening outdoors.
