Red Banana Passionfruit
Getting started -- For the first week, i recommend keeping your plant in its pot to let it recover from being shipped. Keep it in a bright spot with no direct sun during this time.
Pot size -- You can transfer your plant to a 1-5 gallon container, and then move it into a larger pot a few months later. 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. Transplant carefully to avoid disturbing the roots.
Soil -- Like most Passiflora, this one likes moist, rich soil that drains well. A typical soil mix is 2 parts potting soil to 1 part perlite or coarse sand.
Watering -- P. antioquiensis likes regular watering, so that the soil is consistently moist, but not soggy. You may use a moisture meter probe to monitor the moisture levels deep in the root zone.
Temperature & humidity -- This Passiflora does best between 45 and 80 degrees. It reportedly can survive brief, light frosts, but i recommend protecting it from all frost. I'm not sure how much heat it can tolerate, but if it is like some related Tasconias, it may drop its summer flowers if temperatures rise above 85 or 90 degrees.
Indoors, between 40 and 80% humidity is recommended. This species flowers best with cooler nights, so if growing it indoors in a warm-night part of the country, try to lower the temps below 65 at night when the plant nears maturity.
Light -- P. antioquiensis prefers part sunlight. It likes to weave in and out of a bush, trellis, or similar structure so that it chooses how much sunlight it gets. Give it some protection from strong afternoon sun in warmer climates.
Trellising -- Since the blooms hang down by long stems, it's best to grow the vine at least 5 feet off the ground, so the blooms can be appreciated at eye level. You may grow it along an arbor or pergola, covered by translucent plastic. You can also grow it along the roof of a shaded greenhouse, with wires strung across the roof to give the vine something to attach to. The shoots tend to grow at least 12 feet long. If any stems grow too long, simply turn them and send them in another direction. After the first year, do any pruning after flowering, to avoid removing the budding sites.
Fertilizing -- About every 2 months, give a slow-release (pelleted or organic) fertilizer that contains micronutrients.
It's normal for an older leaf to occasionally turn yellow and drop, but if seems excessive, the plant might need more nitrogen fertilizer, or the soil may be too dry.
Flowering and fruiting -- P. antioquiensis can start flowering after it's approximately 1.5 years old. If you want fruit, and you don't have hummingbirds nearby, pollinate the flowers manually using a small brush, or your finger. You may cross-pollinate it with other Passiflora species in the Tacsonia section.
Enjoy your plant!
