The Q&A Archives: Passion Fruit

Question: I have a 2-3 year old Passion Fruit vine that I started from seeds from a Passion Fruit I purchased a the supermarket. It is in a large pot and is 10-12 feet tall. It has never bloomed. When I move it outside this summer, do I need to cut it back in order to get new growth and, hopefully, blooms?

Answer: Passiflora, the passion fruit, will develop flowers when it gets old enough, and when all of its cultural requirements are met. You can prune your plant back to encourage new growth, then provide the sunniest spot available indoors, or full sunshine outdoors. Water as needed to keep the soil moist and fertilize when new growth begins. Since your plant is in a pot, you'll want to fertilize carefully or you'll risk burning the roots. A half-strength liquid fertilizer can be used every 3-4 weeks during the growing season.

When your plant blooms, you'll need to transfer pollen from flower to flower to assure fruit set. Use a cotton swab or a small paint brush to "visit" each flower.

Hope your passiflora is fruitful this summer!
