Days to Germination
5–10 days
Cherokee Purple is one of the most celebrated heirloom tomatoes in the United States. Its modern history begins in 1990, when a Tennessee gardener mailed seeds to tomato historian Craig LeHoullier with a note saying the variety had been in her family for over a century, reportedly originating with the Cherokee people. It has been in widespread cultivation ever since.
The fruit is large — typically 8 to 12 ounces — with a dusky pink-purple shoulder, deep brick-red flesh, and green-tinted shoulders that never fully ripen. The flavor is what made it famous: dense, sweet, complex, with a winey acidity that most modern hybrids lack. It cracks readily and bruises easily, which is why you almost never see it in supermarkets but is exactly why it belongs in a home garden.
For your zone: start indoors around mid-March.
Sow seeds ¼ inch deep in a sterile seed-starting mix. Bottom heat dramatically improves germination rates — aim for a soil temperature of 75–85°F. Seeds will emerge in 5–10 days. Once the first true leaves appear (the second set after the rounded cotyledons), move seedlings under bright light immediately. Insufficient light is the single most common cause of leggy, weak transplants.
Pot up to 4-inch containers once seedlings have two sets of true leaves. Bury the stem deeply — tomatoes root along buried stem tissue, building a stronger root system than transplants set at their original soil line.
Begin 7–10 days before transplanting. Day 1: 1 hour outside in dappled shade, no wind. Add an hour each day, gradually increasing sun exposure. Skip the schedule entirely on cold, windy, or rainy days — a single bad day can set seedlings back two weeks. By the end, plants should be outside full-time and ready for ground.
For your zone: transplant around mid- to late May, once nighttime soil temperatures hold above 60°F.
Tomatoes planted into cold soil sulk for weeks and often never recover their growth potential. Don't rush it — a transplant put out one week late often outproduces one put out one week early.
Dig a hole deep enough to bury two-thirds of the seedling stem, removing lower leaves first. The buried stem will root along its length, anchoring the plant and improving nutrient uptake. Space plants 24–36 inches apart in rows 4–5 feet apart. A handful of finished compost and a tablespoon of bone meal in the hole at planting gives the root system a long, slow nutrient source.
Support. Cherokee Purple is indeterminate and will reach 4–6 feet by season's end. Cage, stake, or string-trellis at transplant time — never later. A 6-foot stake driven 12 inches deep is the most foolproof method for hot, windy conditions.
Water. Deep, infrequent watering beats shallow daily sprinkling every time. Aim for 1–2 inches per week delivered at soil level (drip irrigation or soaker hose, not overhead spray). Inconsistent watering is the single largest cause of fruit cracking and blossom end rot in this variety.
Mulch. A 2–3 inch layer of straw, grass clippings, or shredded leaves applied after the soil warms will regulate soil moisture, suppress weeds, and prevent the soil-splash that spreads fungal disease onto lower leaves.
Pruning. Remove suckers (the shoots growing from leaf axils) up to the first flower cluster. Above that, lighter pruning lets the plant carry more fruit without sacrificing too much vigor. Strip the lowest leaves once plants reach 18 inches — they touch the soil, never see direct sun, and become the entry point for early blight.
Feeding. If you composted at planting, a single side-dressing of compost or balanced organic fertilizer when the first fruits set is enough. Avoid high-nitrogen feeds after flowering begins — they push leafy growth at the expense of fruit.
Cherokee Purple is ripe when the shoulders take on a deep dusky purple and the fruit gives slightly to gentle pressure — like a ripe avocado, not soft. The green-tinted shoulders never fully turn color, even at peak ripeness, so don't wait for them. Twist the fruit upward to break the stem cleanly. Pick every 2–3 days at peak season.
Counter-ripen indoors at 65–70°F for the best flavor. Never refrigerate — refrigeration destroys the volatile compounds that make Cherokee Purple's flavor remarkable. Eat within 4–5 days of harvest.
Cherokee Purple is open-pollinated, so saved seed will grow true to the parent. Scoop seeds from a fully ripe fruit, ferment in water 3 days, rinse, then dry on a plate for two weeks. Stored cool and dry, seeds remain viable for several years.
