History

Aunt Ruby's German Green traces its roots to a Tennessee family and was named for Ruby Arnold, who preserved and shared these seeds with the heirloom tomato community for generations. With its striking lime-green color and shockingly complex flavor, it has earned a devoted following among growers who believe the best tomato doesn't have to be red — and one taste tells you exactly why. It remains one of the most talked-about varieties in the heirloom world.

When to Plant

Start indoors 6–8 weeks before your last frost date and transplant after nights stay consistently above 50°F and all frost danger has passed. Find your frost dates and hardiness zone at the USDA Plant Hardiness Zone Map.

Growing Tips & Planting Dimensions

• Spacing: 24–36 inches between plants; 36–48 inches between rows
• Sow depth: 1/4 inch — cover lightly with fine seed-starting mix
• Germination: 7–14 days at soil temps of 65–70°F
• Full sun — at least 6–8 hours of direct sunlight daily
• Start indoors 6–8 weeks before last frost; transplant after nights stay consistently above 50°F
• Heavy staking or caging required — these are large, vigorous vines with dense, heavy fruit
• Water at soil level to reduce foliar disease pressure and keep vines off the ground
• Rotate crops yearly and mulch soil to reduce disease splash
• Best in well-drained, rich soil with excellent airflow

🌱 Gentle Cover Germination 🌱

Into the surface — thin cover only, no light needed

Aunt Ruby's German Green Tomato seeds are small — but don't let their size fool you. These little seeds carry everything needed to grow into vigorous, productive plants. They just ask for a little extra care at germination. Follow these steps and you'll be well on your way.

How to Germinate Successfully:

1. Start with the right foundation. Use a fine seed-starting mix — not garden soil or coarse potting mix. Sift it if needed. Small seeds need a smooth, even surface to make good contact and germinate reliably.
2. Cover lightly — just barely. Press seeds onto the moist surface and cover with no more than 1/8 inch of finely sifted mix. These seeds don't need light to germinate but they don't want to be buried either.
3. Mist, don't drench. Use a spray bottle to keep the surface evenly moist. Watering from above can wash small seeds away before they ever get started.
4. Warmth is your friend. These seeds germinate best at 65–70°F — basically normal room temperature. A heat mat can help if your space runs cool.
5. Trap the humidity. Cover your tray with a humidity dome or a loose piece of plastic wrap. This keeps moisture and warmth stable while you wait.
6. Give them time. Keep conditions consistent, resist the urge to overwater, and trust the process — they will sprout.
7. Thin with scissors, not fingers. Once seedlings appear, snip extras at the soil line rather than pulling. These roots are close together and pulling one can disturb its neighbors.

Growth Type & Harvest Yields

Indeterminate; produces large, heavy fruit on vigorous vines throughout the season. Yields are moderate to good — fruit size is impressive and each tomato is a showstopper. Caging is essential; the vines are tall and the fruit is dense.

Knowing When to Harvest

• Color does NOT turn red — that's the point. Watch for the skin to shift from bright lime green to a softer, slightly yellow-green or chartreuse tone
• A slight blush of amber or pink at the blossom end is a reliable sign of ripeness
• Fruit should feel slightly soft to gentle pressure — firm but with a little give
• When in doubt, taste one — ripe Aunt Ruby's is unmistakably sweet and complex
• Harvest regularly to encourage continued fruit set through the season
• Store at room temperature — cold destroys the complex flavor this tomato is famous for

Companion Plants & Mutual Benefits

• Basil — repels aphids and complements tomato flavor
• Marigolds — deter nematodes and whitefly
• Carrots — loosen soil around tomato roots
• Borage — repels tomato hornworm
• Parsley — attracts beneficial insects

How to Enjoy

• Slice thick and serve fresh — the color alone is a showstopper on any plate
• Mixed heirloom tomato platters with olive oil, flaky salt, and fresh herbs
• Caprese salad with a twist — green tomato, burrata, and lemon zest
• Slice into salads for color contrast and complex flavor
• Pair with other heirloom varieties for a stunning rainbow tomato spread
