Why Grow Aunt Ruby’s German Green?

• Green-when-ripe beauty: Broad, flattened beefsteaks develop a yellow tint and may show an amber-pink blush at the blossom end.
• Generous slicers: Fruits commonly weigh approximately 12–16 ounces; size varies with growing conditions.
• Rich garden flavor: Juicy green flesh offers sweetness, tang, and a gently spicy complexity.
• Family heirloom: Associated with Ruby Arnold of Greeneville, Tennessee.
• Indeterminate growth: Vigorous vines continue growing and setting fruit while conditions remain favorable.
• Open-pollinated, non-GMO: A distinctive addition to the home vegetable garden.

Planting and Growing

Start seeds indoors 6–8 weeks before your intended transplant date. Sow approximately ¼ inch deep in seed-starting mix, provide warmth for germination, and give seedlings strong light. Harden off gradually before planting outdoors after frost danger has passed and conditions have warmed.

Choose full sun and fertile, well-drained soil. Install a sturdy cage, stake, or trellis at planting time to support vigorous vines and heavy fruit. Water consistently at soil level and mulch to conserve moisture. Maintain airflow while retaining enough foliage to shade developing tomatoes.

For square foot gardening, use 1 plant per sq ft (trellis required) with dedicated vertical training and regular pruning. Allow more room for caged or multi-stemmed plants.

Ripeness Guide

Do not wait for these tomatoes to turn red. Look for a shift from firm green to a warmer yellow-green tone and check for a slight give under gentle pressure. A pink blush can help, but is not required on every fruit. Pick before the tomato becomes very soft and handle gently.
