Growing Tomatillos: From Seedling to Harvest

Tomatillos: Vigorous, Tangy Relatives of Tomatoes

Tomatillos (Physalis philadelphica) are easy-to-grow, productive plants that yield tart, husk-wrapped fruits essential for salsa verde. They share growing requirements with tomatoes but are more cold-sensitive and sprawl aggressively.

Upon Arrival

Unpack immediately. Water if dry. Place in bright, indirect light indoors or sheltered shade outdoors. Harden off over several days, bringing in if frost threatens. Transplant to larger pots if weather remains cold.

Planting Out

• Timing: After frost danger passes and nights stay above 50°F.
• Site: Full sun, rich, well-drained soil. Rotate crops; avoid planting where nightshades (tomatoes, peppers, eggplant, potatoes) grew in the last 3 years.
• Spacing: Follow label recommendations (typically 3–4 feet). Stake, cage, or trellis to manage sprawl.
• Planting: Dig generous holes, amend with compost and low-nitrogen organic fertilizer. Set plants at same depth as in pots. Water well and provide temporary shade for a few days.

Ongoing Care

• Water: Deep, regular watering (weekly or more in heat).
• Fertilize: Side-dress with compost or low-nitrogen fertilizer 2–3 weeks after transplanting and again at bloom.
• Harvest: Pick when husks fill out and fruit is pale green (or purple for colored varieties).
