Passionfruit are best planted from October through till May.

Harvest In

12 - 18 Months

Passionfruit harvest times are between February to June and plants will start to bear fruit about 18 months after planting. After fruit start to appear it will take them around two to three months to ripen. When fruit turn their respective colour and fall off the vine when shaken, this is the time to harvest them.

Prepare

Position

Passionfruit do best in a sunny sheltered position with plenty of space to grow. In areas that are particularly hot plant your passionfruit in partial shade. Provide a strong frame or support for your passionfruit to climb along.

Soil

When planted into the ground Passionfruit likes a moist but free draining soil that is rich in organic matter. To improve the organic content in your soil, break up the soil and add Kings Compost and Kings Sheep Pellets then mix together well. When growing in containers, plant into Kings Container mix. This mix contains added water storage crystals and Saturaid, two products that help maintain moisture in the soil.

Pollination

Pollination is carried out by bees and other insects. To encourage bees in your area, plant-pollinator plants including lavender, cosmos, echinacea, sunflowers or borage.

Plant

When planting into the ground, gently tap the plant out of its pot. Dig a hole twice the depth and width of the plants root ball. Mix Kings Compost into your existing soil at a 50/50 ratio, add Sheep Pellets and Kings Citrus and Fruit Tree Fertiliser, then mix together well. Back fill the hole with this soil, so that when planted the top of the plant’s roots sit level with the surrounding ground. Firm the soil down gently and water in well with Aquaticus Organic Garden Booster. In heavier clay soils, where drainage is likely to be an issue, plant onto a raised mound and sprinkle Gypsum Clay Breaker into the bottom of the hole, this helps slowly condition the soil and will help to break down the clay. When planting into containers plant in Kings Containers mix, as this has water retention crystals in it, which will help in keeping the soil moist. Firm the soil down gently and water in well with Aquaticus Organic Garden Booster.

Care

Watering

Keep plants well watered through the drier months. Deeply watering 3 times a week is more effective than a slight sprinkle every day. Water slowly allowing the water to sink down into the roots, rather than allowing it to run off the top of the soils surface. Add Saturaid into the soil at planting as this will help channel the water deep down into the root zone. If planted in pots never allow the pot to sit in water. When watering avoid wetting the foliage, and if possible, water in the morning.

Feeding

When planted in the ground liquid feed every month with Aquaticus Garden Booster, from Spring through to the end of Autumn, this encourages root growth and increases the microbial activity in the soil. Monthly applications of Kings Sheep Pellets will help with soil conditioning and plant health. In addition apply applications of Kings Citrus & Fruit tree food as per the instructions. If planted into a containers feed with Kings Slow Release Citrus Fertiliser along with monthly applications of Aquaticus Organic Garden Booster this encourages strong roots and a healthy immune system.

Protecting

Fungal problems thrive in damp, humid conditions, and plants are more susceptible if they are water stressed. Proper watering is essential. Protect from any chance of frosts by covering with frost cloth during winter.

Mulching

Mulch around the base of the plants (make sure that the mulch does not come into direct contact with the stem of the plant) with Living Earth More than Mulch. Mulching helps to reduce weeds as well as aiding the soil to retain moisture.

Spraying

Passionfruit are susceptible to fungal conditions and insect pests. Fungal conditions can be treated by applications GroSafe Free Flo Copper. Spray with Aquaticus Bugtrol for insect pests.

Pruning

By encouraging your passionfruit to stay fairly open you increase the airflow around the plant (which reduces humidity and the likelihood of diseases). Do this by pinching or cutting out denser growth. The fruit itself is formed on this season’s wood. So to improve fruiting prune in early spring and, in general, it’s worth pruning one lateral hard each year. To stop your passionfruit vine from getting too big, pinch out the tips when it gets to the size you want.

General Care

When using sprays, chemicals or fertilisers always read the label and follow the instructions. Apply sprays in the evening to avoid harming beneficial insects.

Beginner Tip

When spraying, either spray first thing in the morning or in the evening when bees are not foraging. Avoid spraying in direct sun and onto flowers.

Expert Tip

Small crop numbers, or unripe fruit falling off the vine This is most likely due to poor pollination. Take care not to spray passionfruit flowers when treating your plant for pests or disease. Poor weather such as drought can also interfere. Keep them well watered over the summer.
