📷 Wikipedia: TomatoStarting Iron Lady: indoors or direct sow?
🌾 Sow directly in the garden — Iron Lady is not usually started indoors.
Do not start indoors; plant seedlings directly outdoors only after the last frost has passed and soil temperatures are warm enough for tomatoes.
Soil, care & harvest
Prepare loose, fertile soil with a pH between 6.0 and 7.2 to support root development. As a warm-season crop, start seeds indoors only after the last spring frost date when soil temperatures have warmed sufficiently. Sow seeds at a depth of about one-quarter inch; germination typically occurs within seven to twelve days under consistent warmth.
Space plants twenty-four to thirty inches apart to ensure good air circulation and fruit production. Install sturdy cages or trellises early, as these varieties can grow up to ten feet tall. Maintain high moisture levels through regular watering and apply mulch to retain soil humidity while feeding the plants regularly during the growing season.
Although resistant to many issues, watch for fruitworms, aphids, cutworms, and flea beetles; use row covers or hand-picking to manage them. Blossom end rot may occur if watering is inconsistent. Harvest ripe fruits approximately seventy-five to eighty days after transplanting when they reach full color and flavor.
