If your garden area is used for evening relaxation and entertainment, add the enticing fragrance of moonflowers in the garden. Large white or purple blooms on a climbing vine offer an amazing evening smell when growing moonflowers.
Moonflower plants (Ipomoea alba) are perennial vines in sub-tropical areas, but gardeners with cold winters can successfully grow moonflower plants as annuals. A member of the Ipomea family, moonflower plants are related to the sweet potato vine and the morning glory, with flowers that open in late afternoon. Large, heart-shaped leaves further enhance the attractive moonflower vine.
How to Grow a Moonflower Vine
Moonflowers in the garden do not need much ground space, as they readily climb upward. Provide a trellis or other support for the vigorous vines. Growing moonflowers can reach up to 20 feet, happily twining around anything within their reach. You can pinch back growing moonflowers at the top of the vine, as a part of your care for moonflowers, to force flowering downward.
Moonflower plants grow easily from seed when planted in somewhat fertile soil, but they are adaptable to other soil conditions. In more northern areas, seeds can be started six to eight weeks before the soil outside has warmed. Plant moonflowers outside when outdoor temperatures are consistently 60 to 70 F. (15-20 C.)
Some growers think the crowding of roots in the pot encourages an earlier bloom on moonflower plants. Moonflower vines can grow in large containers or you can plant them in the ground. More moonflowers can be started from root division of existing plants. Mulch the roots of moonflowers in southern zones, and dig them up for winter storage in colder areas.
Light requirements for growing moonflowers are adaptable, but more sun equals more blooms.
Care for Moonflowers
Water small plants regularly and provide additional water as moonflower vines grow.
Regular fertilization at half strength with a high phosphorus fertilizer encourages more blooms on this plant. Too much nitrogen fertilizer may limit blooms and create abundant growth of the foliage.
Now that you’ve learned how to grow a moonflower vine and how to care for moonflowers, be sure to add some to your garden or any sunny area where you can take advantage of beautiful blooms and fantastic evening fragrance, especially in the nighttime moon garden.
