How To Grow Moon Plant Flowers

What is a moonflower?

As a vine, the Moonflower plants can climb to an approximate height of 16′ feet. The vines produce the beautiful flowers come late summer.

Moonflower plants don’t require much space in the garden, as the Moonflower plant grows upwards searching for full sun!

You’ll love the unique heart-shaped leaf as much as the pure white blooms itself as it shoots towards the moon!

For best results to display this fast-growing climbing vine, the plant uses a trellis suitable to support the plant’s growth.

They love to grow on anything and everything they can get their “hands” on!

A trellis serves as the perfect support for them. If you find the growth a bit too overwhelming, pinch the Moonflowers at the top.

The Moonflower plant does best growing in direct sunlight, during warmer months but will grow in partial as well.

If possible, position the moon vine near sunny patios and avoid garages or the side of a house, which could block the sun’s rays for much of the day.

Plant in well-drained soil that doesn’t contain too much clay. Keep soil appropriately moist but not too soggy.

For added encouragement, add a fresh layer of compost and water deeply once or twice a week, more if you’re experiencing a dry spell.

It’s better to under-water rather than overwater, as it can affect the flower’s quality as they grow. The addition of fertilizer isn’t needed if the soil is fertile.

These plants can survive a light frost spell, but cannot bear severe to heavy frost.

In colder zones, plant the moonflower vine in a large container to move indoors when the winter season arrives. Prune vines back and keep in a warm, sunny location.
