Reproduction, propagation and cultivated varieties
Physalis reproduces preferably by seed, although it supports propagation techniques by piles. To improve germination, you can find more information in this guide on Physalis cultivation techniques.
- Extract seeds from ripe, healthy fruits, ideally fermenting the pulp for 24 to 72 hours to improve germination rates.
- Wash the seeds in clean water and dry them in the shade on absorbent paper.
- Sow in a seedbed with rich, disinfected substrate, at a depth of up to 1 cm.
- Provide constant humidity, warmth and protection, maintaining temperatures close to 25 ºC.
- Transplanting is done when the seedlings reach about 15-20 centimeters and show 3-4 true leaves.
Germination is rapid (10-20 days), and vegetative development allows transplants to definitive soil or pots after 2 months from sowing.
Pot and garden cultivation
Physalis is excellent for growing both in orchard, garden as a flowerpotSome practical recommendations:
- Pot size: It must be large (minimum 20 liters per plant) and deep for adequate root development.
- Substratum: Universal substrate enriched with compost and perlite to improve drainage.
- Location: full sun or light semi-shade, avoiding strong winds.
- It is recommended to maintain a distance of at least 40-80 cm between plants on the ground, or use large individual pots to avoid competition for nutrients and space.
- The best results are obtained by performing an intermediate transplant to larger pots before the final transplant to the garden or orchard.
Pruning, staking and maintenance
El PHYSALIS It is a vigorous grower and requires pruning and staking techniques for healthy development and to maximize fruit production and quality:
- Formation pruning: It consists of eliminating the shoots that emerge at the base of the main stem up to the first 30-40 cm in height to reduce relative humidity and prevent diseases.
- Sanitary pruning: remove dry, old or diseased branches to reduce sources of infection.
- Pruning after harvest: Some varieties allow for more severe pruning to promote new flowering and vigorous branching.
- Tutored: Essential, especially during fruit production. Branches can break due to the weight of the fruit, so the use of individual stakes or online support systems is recommended.
- In pots, four canes can be used and formed into a cage with wire to direct growth.
Proper staking and pruning directly influence the yield, ventilation, and overall health of the plant.
Fertilization and manure
El regular subscriber It is key to consistent production and quality fruit. The nutritional needs of Physalis are similar to those of other nightshades:
- Base fertilizer: Incorporate mature compost, worm humus or organic fertilizers at the time of planting.
- Fertilization in production: Every two months add between 30-200 grams of fertilizer with high phosphorus and potassium content (10-30-10) or liquid tomato fertilizer to stimulate flowering and fruiting.
- In organic farming, maintain with well-made compost or manure every two months.
- Avoid excess nitrogen, which promotes vegetative growth but reduces fruiting and quality.
Irrigation and water needs
The Physalis needs frequent and moderate watering throughout the growth and development stage of fruits, but without flooding the substrate:
- Hand watering: wait for the substrate to begin to dry on the surface (the leaves look droopy when they require water).
- Avoid water accumulation in the pot saucer and prioritize well-drained soils.
- During periods of intense heat or drought, mulching is recommended to maintain soil moisture and temperature.
- In winter, reduce watering frequency, especially if the weather is humid or rainy.
Harvesting, preservation and post-harvest of Physalis
La Physalis harvest It is harvested when the calyx or mat changes color from green to straw-gold and dries, indicating that the fruit inside is ripe and ready to be harvested. Harvesting typically begins 60-80 days after flowering, and the harvesting period can extend up to 11 months from the first harvest.
- Harvesting must be manual, to prevent damage to the calyx, making it easier to preserve during storage.
- Conservation: The fruits can be stored in their wrapping for up to a month at room temperature, away from direct light and in dry conditions. Without the wrapping, the fruit's shelf life is reduced to just a few days.
- The fruit continues to ripen and soften after harvest, so it is recommended to consume or process it fresh, or store it refrigerated in a dry, ventilated container to extend its shelf life.
- Under optimal conditions (low temperature and humidity), it can be preserved for several months if the calyx is dry and intact.
Common pests and diseases in Physalis
Although physalis is relatively hardy, pests and diseases can occur, especially in conditions of excessive humidity or poor ventilation. The main threats are:
- Flea beetle (Epitrix sp.): small insect that perforates leaves.
- Whitefly (Trialeurodes vaporariorum): It settles on the underside of leaves; it sucks sap and can transmit viruses.
- Red spider: causes small spots and general weakness.
- Woodlouse: It develops attached to stems and leaves in dry environments.
- Alternaria sp.: One of the most common fungi, it begins with black spots on older leaves until they become necrotic. It usually appears due to excess humidity or poor ventilation.
For biological and preventive management:
- Maintain health by regularly pruning and removing infected plant debris.
- Monitor for pests and use organic treatments such as soapy water, neem oil, or color traps.
- Avoid sprinkling water on the aerial part and do not over-wet the foliage.
- Remove and destroy affected fruit to prevent the spread of disease.
Production, performance and life cycle of Physalis
The Physalis production cycle, from planting to harvestable fruit, is approximately 9 months. From the first cut, the plant can remain productive for up to 11 additional months, after which fruit production and quality gradually decline.
- Optimal performance: In well-managed crops, yields can reach between 14 and 20 tons per hectare, with an average of 300 fruits per plant in each harvest season.
- It is a crop that can be renewed by cuttings to maintain productivity in successive cycles.
- In home gardens or potted production, the plant is very grateful and allows harvesting for several months a year.
Physalis in gastronomy and culinary uses
Physalis is a versatile fruit in the kitchen:
- You can eat it fresh in fruit salads, desserts, and fruit salads, or use it in jams, sauces, chutneys, yogurts, ice cream, and creative pastries.
- In South America and other countries, it is used for juices, liquors, and processed products such as preserves and yogurts.
- Due to its sweet and sour flavor, it is ideal as a decoration for dishes and cakes, and pairs well with fresh cheeses and meat sauces.
It is also common to combine it with citrus fruits or nuts to enhance its nuances.
Practical tips and tricks for successful Physalis cultivation
Key considerations and recommendations supported by expert practice:
- Sow in a protected seedbed during late winter or early spring to speed up the cycle and obtain vigorous seedlings before transplanting.
- Avoid clayey, heavy, or highly alkaline soils to prevent rot and nutritional deficiencies.
- Maintain regular weed control to avoid competition for nutrients and water.
- Stake from the early stages of development to prevent branches from breaking under the weight of the fruit.
- Perform periodic sanitary pruning and remove old or affected leaves to improve ventilation and light.
- Avoid direct sowing of seeds in the field, as their small size and water requirements mean that seedlings thrive best in a protected seedbed.
