Tomatillo Seeds - Aunt Molly's - Physalis pruinosa

3, 4, 5, 6, 7, 8, 9, 10, 11

USDA Zones 3-11 - Grows as a warm-season annual across all zones. Planting times should be adjusted based on local frost dates and soil temperature requirements for successful germination.

Best performance in Zones 4-10 where long, warm summers provide ideal growing conditions for maximum fruit production and extended harvest periods through early fall.

Northern zones (3-5) - Start seeds indoors 4-6 weeks before the last frost date or direct sow after all danger of frost has passed and the soil has warmed. Consider using row covers or season extenders to maximize the growing season in areas with shorter summers.

Hot climate zones (9-11) - Plant in early spring for a summer harvest, or in late summer for fall production in desert regions where extreme summer heat may stress plants during peak temperatures.

Soil temperature critical - Requires warm soil of at least 65F for germination across all zones, with optimal soil temperature of 70-85F ensuring quick sprouting and strong plant establishment.

Growing season needs - Requires 70-80 frost-free days from transplanting for full production potential, making it suitable for all zones when planted at appropriate times relative to local frost dates.

When to Plant:
Start seeds indoors 4-6 weeks before your last expected frost date. For best germination, use a heat mat to maintain a consistent soil temperature of 70-85F. You can also direct sow seeds into the garden after all danger of frost has passed and the soil has warmed to at least 65F.

Location and Soil:
Choose a location that receives full sun (at least 6-8 hours of direct sunlight per day). 'Aunt Molly's' thrives in well-draining, fertile soil rich in organic matter. Amend heavy clay soils with compost to improve drainage and aeration. A soil pH between 6.0 and 7.0 is ideal.

Starting Seeds Indoors:

Fill seed starting trays or small pots with a high-quality, sterile seed starting mix.

Sow 2-3 seeds per cell or pot, planting them approximately 1/4 inch deep.

Lightly cover the seeds with soil and gently water to moisten the mix.

Place the trays in a warm, sunny location or under grow lights. A heat mat will significantly speed up germination.

Once seedlings emerge, thin to one plant per cell, keeping the strongest one.

Water consistently to keep the soil moist but not waterlogged.

Harden off seedlings for 7-10 days before transplanting outdoors. This process gradually acclimates them to outdoor conditions.

Transplanting Outdoors:

Transplant seedlings into the garden after all danger of frost has passed and the soil has warmed.

Space plants 24-36 inches apart in rows 3 feet apart.

Dig a hole slightly larger than the root ball. Place the plant in the hole and backfill with soil, gently firming it around the base.

Water thoroughly after transplanting to help the plant settle.

Care and Maintenance:

Watering: Provide consistent moisture, especially during flowering and fruiting. Water deeply and infrequently to encourage a strong root system.

Fertilizing: Amend the soil with compost before planting. You can also use a balanced, all-purpose fertilizer every 4-6 weeks during the growing season.

Mulching: Apply a 2-3 inch layer of mulch (such as straw or wood chips) around the base of the plants to conserve moisture, suppress weeds, and regulate soil temperature.

Staking: While 'Aunt Molly's' has a bushier habit than traditional tomatillos, some staking or caging may be beneficial to support heavy fruit loads and keep the plants off the ground.

Harvesting: The fruit is ready for harvest when the papery husk turns a light brown color and splits open. The ripe fruits will naturally fall to the ground when ready. The fruit inside should be a shiny yellow color. Harvest frequently to encourage continuous production.
