Everything it needs
9 essentials at a glance
Watering
Pepino plants prefer consistently moist soil but should not be waterlogged.
Water them deeply once a week, allowing the top inch of soil to dry out between waterings. In hotter months, increase frequency to twice a week. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and leaf drop.
Light
Pepino thrives in full sun, requiring at least 6-8 hours of direct sunlight daily.
Ideal placement is in a south-facing garden bed or a sunny patio. While it can tolerate partial shade, reduced light may lead to leggy growth and fewer fruits.
Soil
The ideal soil for Pepino is well-draining, sandy loam with a pH range of 6.0 to 7.0.
Ensure good drainage to prevent root rot; a recommended potting mix includes equal parts of peat, perlite, and compost.
Humidity
Pepino prefers moderate humidity levels around 50-70%.
To increase humidity, mist the plant regularly or place a humidifier nearby. Signs of humidity stress include browning leaf tips and wilting.
Temperature
Pepino grows best in temperatures between 70-85°F (21-29°C) and is hardy in zones 9-11.
It can tolerate brief periods of heat up to 95°F (35°C) but is sensitive to frost, so protect it during cold snaps.
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10 every 4-6 weeks during the growing season.
In fall, reduce feeding as the plant enters dormancy. Signs of nutrient deficiency include yellowing leaves (nitrogen), poor fruit development (phosphorus), and stunted growth (potassium).
Pruning
Prune Pepino in early spring to remove dead or damaged branches and to shape the plant.
Use clean, sharp pruning shears. Deadheading spent flowers can encourage more blooms and fruit production.
Repotting
Repot Pepino every 1-2 years or when roots begin to outgrow the pot.
Choose a pot that is 1-2 inches larger in diameter. Signs it needs repotting include roots growing out of the drainage holes and stunted growth. To repot, gently remove the plant from its current pot, loosen the roots, and place it in fresh potting mix.
Propagation
Pepino can be propagated through stem cuttings or seeds.
For stem cuttings, take a 4-6 inch cutting from a healthy plant, remove lower leaves, and place it in water or moist soil. For seeds, sow them in spring, covering lightly with soil. Keep the soil moist until germination, which takes about 2-3 weeks.
When it's unhappy
Yellow leaves
Why it happens
Over-watering or nutrient deficiency.
How to fix it
Check soil moisture and adjust watering schedule. Fertilize with a balanced fertilizer if nutrient deficiency is suspected.
Wilting
Why it happens
Under-watering or extreme heat.
How to fix it
Increase watering frequency and ensure the plant is in a shaded area during peak heat.
Fruit drop
Why it happens
Stress from temperature fluctuations or inadequate pollination.
How to fix it
Ensure stable temperatures and consider hand-pollinating flowers if necessary.
Powdery mildew
Why it happens
High humidity and poor air circulation.
How to fix it
Improve air circulation around the plant and treat with a fungicide if necessary.
Root rot
Why it happens
Over-watering and poorly draining soil.
How to fix it
Allow the soil to dry out and repot in fresh, well-draining mix if necessary.
Care through the year
Spring
In spring, focus on pruning and fertilizing as new growth begins. Ensure the plant has adequate sunlight and water as temperatures rise.
Summer
During summer, maintain consistent watering and monitor for pests. Provide shade during extreme heat and continue fertilizing every 4-6 weeks.
Fall
In fall, reduce watering as the plant prepares for dormancy. Harvest ripe fruits and consider bringing potted plants indoors if temperatures drop.
Winter
In winter, protect Pepino from frost and reduce watering significantly. If indoors, ensure it gets enough light and maintain a stable temperature.
Toxicity & Safety
Pepino is generally considered non-toxic to pets and children. However, ingestion of large quantities may cause mild gastrointestinal upset. The leaves and unripe fruit are less palatable and should be avoided.
Good to know
Why are my Pepino leaves turning yellow?
Yellowing leaves on a Pepino can indicate over-watering or a nutrient deficiency. Check the soil moisture and adjust your watering schedule accordingly, and consider fertilizing if the plant has not been fed recently.
How often should I water my Pepino?
Water your Pepino deeply once a week, allowing the top inch of soil to dry out between waterings. In hotter weather, you may need to increase watering to twice a week.
What is the best light for Pepino plants?
Pepino plants thrive in full sun, requiring at least 6-8 hours of direct sunlight each day. A south-facing location is ideal for optimal growth and fruit production.
How do I propagate Pepino?
You can propagate Pepino through stem cuttings or seeds. For cuttings, take a healthy 4-6 inch stem, remove lower leaves, and place it in water or moist soil. For seeds, sow in spring and keep the soil moist until germination.
What temperature is best for growing Pepino?
Pepino prefers temperatures between 70-85°F (21-29°C). It can tolerate brief heat but is sensitive to frost, so protect it during cold weather.
How do I prevent powdery mildew on my Pepino?
To prevent powdery mildew, ensure good air circulation around the plant and avoid overhead watering. If it occurs, treat with a fungicide and improve air flow.
When should I prune my Pepino?
Prune your Pepino in early spring to remove dead or damaged branches and to shape the plant. This encourages healthy growth and fruit production.
