Chupon de Malinalco Tomatillo

25 Seeds

Chupon de Malinalco is a Mexican heirloom, open-pollinated tomatillo known for its distinctive elongated, pointed yellow fruits enclosed in papery husks. The fruits can reach about 10 cm long and have a sweet-tart, citrusy and fruity flavor. They can be used fresh, roasted, or cooked into salsas, sauces and other dishes.

The plants are vigorous and branching, generally reaching around 90–120 cm, although larger plants are possible under favorable conditions. Because the branches can become heavy with fruit, light staking or a cage can be useful.

Important: Tomatillos are generally self-infertile. Grow at least two plants so that flowers can cross-pollinate and produce a good crop.

🌱 Best Planting Time

For Gulf conditions, grow Chupon de Malinalco during the milder warm periods and avoid the most intense summer heat.

• Gulf region: September–April
• Kuwait: September–November and February–April
• Best periods in Kuwait: October–November and late February–March
• Avoid starting young seedlings outdoors during extreme summer heat.

🌿 How to Plant the Seeds

1. Use a fine, fertile, well-draining seed-starting mix.
2. Moisten the growing medium before sowing.
3. Sow the seeds about 0.5–1 cm deep.
4. Cover lightly with fine soil.
5. Keep the medium consistently moist but never waterlogged.
6. Place the seed tray in a warm, bright location.
7. Once seedlings emerge, provide strong light to keep them compact and healthy.
8. Start seeds in individual cells or small pots so the roots can be transplanted with minimal disturbance.

🌡️ Germination

• Ideal temperature: approximately 21–29°C
• A warm seed-starting environment helps encourage faster germination.
• Germination time: approximately 7–20 days
• Keep the growing medium evenly moist.
• Avoid excessive heat during germination.

Different seed sources report slightly different germination periods, so some variation is normal.

🌱 Transplanting

Transplant when seedlings are strong and have several true leaves.

• Start seeds approximately 6–8 weeks before outdoor planting when using a protected seed-starting schedule.
• Plant spacing: 45–60 cm
• Row spacing: 90–120 cm
• Harden seedlings gradually before moving them outdoors.
• Transplant after the weather has become consistently warm.
• Provide a stake, cage or other support as plants develop.

Grow at least two plants together for reliable pollination and fruit production.

☀️ Sunlight

• Provide full sun, ideally around 6–8 hours of direct sunlight.
• Morning sun is particularly useful in the Gulf.
• During periods of extreme heat, light afternoon shade can reduce heat stress.
• Maintain good spacing and air circulation around the plants.

💧 Watering

• Keep the soil evenly moist while seedlings are establishing.
• Water deeply when the upper soil begins to dry.
• Increase watering during flowering and fruit development when necessary.
• Avoid constantly saturated soil.
• Mulching can help retain moisture and moderate root-zone temperatures.
• Container-grown plants may require more frequent watering during hot weather.

🌱 Soil

Use fertile, loose and well-draining soil.

A suitable mixture can include:

• Quality vegetable-growing soil
• Mature compost
• Perlite, pumice or coarse material to improve drainage

A mildly acidic to neutral or slightly alkaline soil can be suitable.

Avoid heavy soil that remains wet around the roots.

🌿 Fertilizing

• Mix mature compost into the soil before planting.
• Use a balanced vegetable fertilizer during early growth if needed.
• Avoid excessive nitrogen, which can encourage excessive foliage.
• Provide moderate feeding during flowering and fruit development.
• Container plants may benefit from regular light feeding because nutrients are depleted more quickly.

🌼 Flowering & Fruit Development

The plant produces small yellow flowers followed by tomatillos enclosed in papery husks. Chupon de Malinalco is considered an early tomatillo, with some sources reporting around 70 days to maturity, while other growing conditions may result in approximately 80–90 days or longer.

The fruits develop from green to lemon-yellow as they mature.

🧺 Harvesting

For fully ripe fruit:

• Allow the fruit to fill the papery husk.
• The husk changes from green toward brown as it matures.
• A ripe husk may become dry and begin to split open.
• Mature fruit develops its characteristic yellow color and sweeter flavor.
• Harvest regularly to encourage continued production.

For culinary use, the fruits can also be harvested before complete ripeness depending on the desired flavor.

🪴 Growing in Containers

Chupon de Malinalco can be grown in large containers.

• Use 30–40 L or larger per plant.
• Choose a deep, sturdy container with excellent drainage.
• Provide a cage or strong stake because branches can become heavy with fruit.
• Grow at least two plants in separate containers or one sufficiently large growing area for pollination.
• Move containers to a more protected position during periods of extreme Gulf heat.

🔥 Gulf Climate Tips

• Start seeds indoors or in a protected area when outdoor temperatures are too extreme.
• Avoid germinating seeds in direct summer heat.
• Use morning sun and light afternoon protection during very hot periods.
• Give plants sufficient space because they can become broad and bushy.
• Support the branches before they become heavily loaded with fruit.
• Maintain good airflow, particularly in humid coastal Gulf areas.
• Grow at least two plants together for reliable fruit production.
• Avoid planting immediately after other Solanaceae crops such as tomatoes, peppers, eggplants or potatoes when possible.

🌱 Growing Tip: In Kuwait, start Chupon de Malinalco Tomatillo seeds during October–November or late February–March, protect young plants from extreme afternoon heat, and grow at least two plants together for better pollination and fruit production.
