Passiflora membranacea


Please be careful removing your plant from it's packaging.

Getting started -- Your plant was grown in filtered light, so plan on acclimating it to direct sun slowly. Start it with either filtered sun or early morning sun and gradually increasing the exposure every few days.  If the plant should wilt, give it more shade for a few days.

Pot size -- You can transfer your plant to a 1-5 gallon container.  Transplant to a larger pot whenever the roots start circling the bottom.  Within 12-18 months, it should have approximately 10 gallons or more.. although a smaller pot might work if the vine is pruned back regularly.

Soil -- Like most Passiflora, this one likes moist, fairly rich soil that drains well.  A good soil mix is 2 parts potting soil to 1 part perlite or coarse sand.

Potting up -- Before repotting, water the soil, so the soil ball doesn't break apart, which can damage the roots.  For the first week after repotting, shade from sun, and give no fertilizer.

Watering --  Aim to keep the soil evenly moist (but not soggy). 

Temperature & humidity -- This Passiflora seems to do best between 45 and 80 degrees.  It reportedly can survive a few degrees of frost, but i recommend protecting it from all frost.  I'm not sure how much heat it can tolerate, but if it is like some other highland Passifloras, it might not flower if temperatures rise above the upper 80s.

Light -- P. membranacea prefers full sun, however some afternoon shade may be necessary in warmer areas.  If you grow it in a pot, keep the pot shaded to avoid overheating of the roots.

Trellising -- The vine should be given something to climb on, like a large trellis, arbor, or the side of a home  You can grow it along an arbor or pergola.  You can also grow it along the roof of a greenhouse, with wires strung across the roof to give the vine something to attach to.  The vine can potentially grow 40 feet or more and can smother trees, so choose a site carefully.  You may cut back any unwanted growth.  After the first year, do any pruning after flowering, to avoid removing the budding sites.

Fertilizing -- After the first month, give monthly feedings during periods of active growth with an all-purpose fertilizer.  It's normal for older leaves to occasionally turn yellow and drop, but if it's excessive, the plant might need more nitrogen.

Flowering and fruiting --  The plant blooms from Summer through Fall.  If you want fruit, you will need a 2nd plant, although it might be able to cross-pollinate with certain Decaloba-type Passiflora species.

Pests to watch for -- spider mites (tiny "dots" under the leaves), aphids.

Enjoy your plant!
