How to Garden Passiflora Alata

Updated March 23, 2017

Passiflora alata is a passionfruit vine, native to Brazil. Blooming in fragrant red and purple flowers, from late summer to early fall, P.alata bears edible yellow fruit, 4 to 5 inches long. Passiflora alata is a tropical vine and must be grown in a frost-free climate.

Grow the Passiflora alata in full sun in a warm area of the garden.

Give the vine a sturdy support structure. Some gardeners grow it next to a fence or use a strong trellis or arbor.

Add a 3-inch layer of organic mulch around the base of the Passiflora alata every spring. Keep it 2 inches from the vine and spread it out in a 1-foot radius.

Water the Passiflora alata to keep the soil moist at all times. It is especially important to pay attention to the moisture content of the soil during fruiting.

Fertilise the passionfruit vine with 1.36kg. of 10-5-20 formula fertiliser, four times a year. Sprinkle the fertiliser on the soil, 6 inches from the base of the vine and spread it in a 1-foot diameter. Water the top 4 inches of soil after fertilising.

Prune the Passiflora alata after harvest in warm regions of the country and in early spring where the weather is cooler. Cut the plant back to keep it growing on its support structure. Also remove any dead, dying or weak stems. Cut other stems back by at least one-third of their length.
