How to grow Moonflower Vine

Dilute liquid fertilizer during growing period, but keep drier in winter.

At least 6 hours of sunlight a day for flowering.

In frosty areas, cut off tops in autumn and cover roots with mulch.
In really cold areas, give up and grow them as annuals.

Cut a notch in the seed with a file, or soak for several hours in sulfuric acid or overnight in warm water.
Sow in autumn if winters are mild (then you don’t have to worry about seed pre-treatment), otherwise in spring.

Try to aim for a seed spacing of at least 11.7 inches (30.0 cm) and sow at a depth of around 0.98 inches (2.5 cm). Soil temperature should be kept higher than 16°C / 61°F to ensure good germination.

Plant 5-7 well-rooted seedlings in a 8-12" pot.
Water only moderately until pot is filled with roots.
Crowding is thought to improve flowering.

Help 1"-2"- seedlings to twine around trellis, etc.

Can also be grown from cuttings, layering, root division, tubers on stems.

Ensure that temperatures are mild and all chance of frost has passed before planting out, as Moonflower vine is a tender plant.
