Green Zebra Tomato

Start seeds indoors 5 to 6 weeks before your transplant date. Sow seeds 1/8 inch deep in seed-starting mix and keep at a constant 75 to 85 degrees Fahrenheit with moderate moisture. Seeds typically sprout in 5 to 7 days. Once the first true leaves appear, pot up seedlings to 50-cell trays or 4-inch pots and grow at a cooler 60 to 70 degrees Fahrenheit with complete fertilizer until hardening off. Avoid starting too early, as leggy, root-bound, or flowering transplants cause stunting and reduce early production.

Transplant seedlings outdoors after all frost danger has passed and soil has warmed. Space plants 24 inches apart with 42 inches between rows. Harden off seedlings gradually by exposing them to outdoor conditions over several days before planting. Do not transplant flowering or severely root-bound seedlings, as this stresses the plant and reduces early fruit production.

Harvest Green Zebra when fully ripe: the skin will shift from white or pale stripes to bright yellow stripes against the chartreuse base, indicating peak ripeness. The fruit should yield slightly to gentle pressure. Harvest by twisting and pulling, or use pruning shears to avoid damaging the plant. For green fruit, ripen indoors in a cool, dark area with fruit not touching one another. Do not refrigerate ripe fruit, as cold temperatures diminish flavor.

Green Zebra is an indeterminate variety that grows continuously throughout the season, reaching 5 feet or taller. Use basket-weave trellising with 5 to 6-foot stakes placed every 2 to 3 plants, using heavier t-posts at intervals and the bed ends for stability. For plants that outgrow manageable height and become difficult to harvest, prune the top once they reach the desired size. Avoid aggressive pruning that removes excessive foliage, as the plant needs leaves to support fruit ripening.
