Gardening Know How is here to help with all your gardening questions, and when it comes to growing and caring for passion flower vines, it’s no different. If you have a passion for plants, then no doubt passion flower is on that list. While we receive a number of inquiries regarding these plants, here are the 10 most commonly asked questions about passion flowers.
flower is pretty easy to start. If you have an existing plant, or know a
friendly neighbor gardener who does, you can take a cutting. Cut off a 4- to 6-inch
(10 to 15 cm.) piece of stem just below a node. Take off the bottom leaves and
dip the end of the stem in rooting hormone and then potting soil. Keep it warm
and moist and out of direct sunlight. You can also start passion flower from
seed. Score seeds gently with sandpaper and soak them in warm water for 24
hours. Put the seeds in soil to a depth of about a quarter inch (0.5 cm.) and
keep covered with plastic. Put the seedlings in sunlight once you see leaves.
Watering issues are most likely to blame for yellowing
passion flower leaves. Check the soil and provide extra water if it is dry
and if the conditions have been especially hot. If the soil is consistently
moist and it isn’t too hot, you may need to back off on watering.
There are likely some environmental issues
preventing your vine from blooming. Passion flower actually prefers not to
be fertilized, so if you have been feeding it, stop. Sunlight can also be a
problem. The vine needs full sun to bloom, so consider transplanting if
necessary. The soil around the roots should be moist but also must drain well.
Overwatering and underwatering could prevent blooms. Your vine may also simply
be too young to flower. Most passion flower plants will take a few years to
establish before flowering.
a passion flower vine regularly to promote thicker growth
and flower and fruit production. During late winter, remove any damaged or dead
stems. Then, cut back stems in general by about a third of the plant. The vine
will come back more vigorously and fuller. If you have an old, overgrown vine,
you can prune it back to life. Cut it back to just a few strong stems. New
stems should come in, and you can train these to develop a nice, tidy vine.
flower can grow well in a container. But, in order to thrive it, will need
a large pot. Regularly transplant it to a bigger pot as the plant grows.
Watering in a container is especially important. You may need to water more often,
but also be sure that the pot drains. Whether in a container or in the ground,
your passion flower will need full sunlight.
There are a few
potential problems that can cause passion fruit to drop early. An irregular
watering schedule may trigger the issue. Passion flower vine needs regular
watering but also good drainage. Cold temperatures can be a problem too, as can
pests. Mite damage may cause fruit drop, as can fruit vine hoppers. Check for
and manage any infestations. Finally, a lack of trace elements in the soil may
cause fruit to drop. Get your soil tested through the local extension office to find out if it’s missing anything.
It depends on where
you live. Passion flower vine is considered hardy outdoors in USDA zones 6 to 9. It may be fine in zone
5, but that’s pushing it. If your temperatures get down to the negative double
digits Fahrenheit (about -24 and lower Celsius), the vine probably will not
survive the winter. You can, however, overwinter the plant indoors.
plant passion flower intentionally, but it can also be an invasive plant, especially wild varieties. If you
need to eliminate or control vines, first try pulling out new growth. If you
want to get rid of all of the vines, you’ll need to dig out the roots using a
shovel. Any remaining roots will regrow. Alternatively, you can use herbicides.
Those with picloram, dicamba, or 2,4-D, triclopyr should work with this woody
The color of the fruit will change when it ripens, but it
depends on the variety. Ripe
passion fruit will also drop from the vine. If you harvest the seeds, start
germinating them when fresh. Score the seeds with sandpaper and soak them in
warm water for about 24 hours. Then you can start them as you would other
seeds: in a seed tray with moist potting soil. Keep the seeds moist and then
place in sunlight once leaves emerge.
You can transplant
a passion flower vine, but it can be difficult. The roots go deep, and
you’ll need to dig most of them out for a successful move. The best time to
attempt a transplant is in late winter or early spring before active growth
begins for the new season. Dig out the roots when the soil is moist to make it
easier. Make sure to plant the roots as deeply as they were in the original
location for the best results.
