Passion flowers can be propagated from cuttings taken in spring before the first frost of the season.

Take a 6 inch (15 cm) cutting and remove the lower leaves. Place into potting mix and keep indoors over winter. They can be planted in the garden in spring the next year.

Passion flowers can also be propagated by layering. Strip the leaves from a section of stem and bury it under the soil. Keep the stem in place with a piece of wire or a small stone. It should root in a couple of weeks.

Growing Passion flowers from seeds

Passion flowers can be extremely slow to germinate, but soaking the seeds for a couple of days before planting can help.

The seeds need light to germinate, so just place the seeds on the surface of the potting mix and gently pat them down.

Keep the soil moist and transplant them to larger pots when they have a few sets of leaves.

Plants that are grown from seed can take many years to flower, so propagation from cuttings is best.

Watering Passion flower vines

Passion flowers need to be watered regularly throughout summer, especially in hot weather. The soil should not dry out too much between waterings.

A layer of mulch will help the soil to retain moisture and keep the roots cool.

Fertilizer

Passion flower plants need to be fertilized every 4 to 6 weeks over spring and summer.
