When to plant
Plant Physalis in spring after the risk of frost has passed and the soil has begun to warm. In mild climates, planting can also be done in early autumn. Avoid planting in cold, wet soil. If starting from young plants, harden them off gradually before planting outdoors.
Where to plant
Choose a sunny, warm location with at least 6 hours of direct sunlight daily. Physalis thrives in borders, kitchen gardens and sheltered sites. For fruiting types, full sun is essential for good yields. Avoid deep shade, as it reduces flowering and fruiting.
Preparing the soil
Loosen soil to 25–30 cm depth and enrich with compost or well-rotted manure. Physalis prefers fertile, well-drained soil that holds some moisture. Improve sandy soil with compost, and lighten heavy clay with grit and organic matter.
Preparing the plants
If planting young plants, water them well in their pots before planting. For bare-root plants, briefly soak the roots in lukewarm water for 15–20 minutes. Remove only damaged roots if necessary and handle the stems gently.
Planting the plants
Plant Physalis at the same depth as they were growing in their pot or as indicated on the bare-root crown. Space plants 45–60 cm apart to allow good airflow and room for spreading. Firm soil around the roots and water thoroughly after planting.
After planting
Keep the soil consistently moist for the first few weeks to help roots establish. Apply a light mulch around (but not against) the stems to conserve moisture and suppress weeds.
During growth
Water regularly during dry periods—Physalis performs best with even moisture. Apply a balanced fertiliser in spring to support flowering and fruiting. Remove any competing weeds and consider staking taller varieties to keep them upright. For fruiting types, pinch out overly weak or wandering side shoots.
After flowering / end of season
For ornamental Physalis, leave the lanterns to dry on the plant for the best colour. At the end of the season, cut back stems to ground level once they have died back naturally. In cold climates, mulch crowns lightly in winter for protection.
Extra tips
Physalis can spread by underground runners—plant in root-barrier beds or containers if you want to limit spread. They pair beautifully with grasses and late-summer perennials. Fruiting types are ideal for sunny patios, kitchen gardens and edible borders.
