Thessaloniki Tomato Seeds belongs to the long record of tomato selection that began with domestication in the Americas and continued through farmers, gardeners, public breeders, market growers, and seedkeepers. Where a precise breeder or family chain is not supported by a primary record, this page does not invent one.\u003c\/p\u003e\n\u003cp\u003eThe variety is described through observable fruit, plant habit, use, and the records kept by people who continue to grow it. Thessaloniki is maintained in this catalog as an open-pollinated (op) slicing tomato. Published records support the cultivar name and the observable fruit and plant traits used on this page.\u003c\/p\u003e\n\u003cp\u003eWhere the available documentation does not preserve a complete breeder, family, or community chain, Species-level tomato domestication in Andean South America is kept separate from the later history of this named cultivar, which may involve farmers, public breeders, gardeners, market growers, and seedkeepers in other regions. The listed heritage classification is Heirloom; it describes the catalog classification and does not prove an undocumented origin story.\u003c\/p\u003e\n\u003ch2\u003eFruit, flavor, and kitchen use\u003c\/h2\u003e\n\u003cp\u003eThessaloniki is best for fresh slicing, sandwiches, salads, and general kitchen use. The expected flavor is classic sweet-tart tomato flavor with juicy flesh and balanced acidity. Fruit is described as red and about 5 to 7 oz. Use a tested current recipe for home canning; cultivar name alone does not establish safe acidity. Thessaloniki is especially useful for fresh slicing, sandwiches, salads, and general kitchen use. Flavor and eating quality are described as classic sweet-tart tomato flavor with juicy flesh and balanced acidity. For home canning, use a tested current recipe; cultivar name, color, or perceived sweetness does not establish safe acidity.\u003c\/p\u003e\n\u003ch2\u003eHow to grow Thessaloniki\u003c\/h2\u003e\n\u003cp\u003eStart Thessaloniki indoors about 6 to 8 weeks before the last expected frost. Sow 1\/8 in deep in a warm, evenly moist seed-starting mix; expect 6–12 Days near 75–90 °F. Give seedlings strong light, move them into larger cells before they become root-bound, and harden them gradually before planting outside after frost danger.\u003c\/p\u003e\n\u003cp\u003ePlant in full sun with loamy soil near pH 6.0–6.5. Space plants 30 in apart and rows 36 in apart. Maintain moderate moisture, mulch after the soil warms, and keep foliage off wet soil where possible. Set up stake at transplanting. The indeterminate plant reaches 61–72 in.\u003c\/p\u003e\n\u003ch3\u003eSeason care\u003c\/h3\u003e\n\u003cp\u003e• Give Thessaloniki strong light from emergence so seedlings remain stocky rather than stretched.\n• Install stake when transplanting; adding support after vines are large can damage roots and stems.\n• Water at the soil line and maintain even moisture to reduce cracking, blossom-end rot risk, and stress-related fruit problems.\n• Harvest when the fruit has reached its cultivar-specific color and gives slightly to gentle pressure; color alone can be misleading on green, purple, or striped varieties.\n• Use 60-69 Days as a planning range rather than a guaranteed calendar date; weather and transplant stress can shift first harvest.\u003c\/p\u003e\n\u003ch2\u003eHarvest and maturity\u003c\/h2\u003e\n\u003cp\u003e60-69 Days from transplanting under suitable conditions. Harvest when the cultivar-specific color has developed and the fruit gives slightly to gentle pressure; green-ripe, striped, purple, and dark cultivars require more than a simple red-color test.\u003c\/p\u003e\n\u003ch2\u003eSaving seed\u003c\/h2\u003e\n\u003cp\u003eTomatoes are primarily self-pollinating, but occasional crossing can occur. To maintain Thessaloniki, save seed from several healthy true-to-type plants and bag unopened flower clusters when extra isolation is needed. Allow labeled fruit to ripen fully, squeeze the seed and gel into a container, ferment briefly until the gel releases, rinse clean, and dry the seed in a thin labeled layer. Store the finished lot cool and dry with the year, source, plant count, and isolation notes.\u003c\/p\u003e\n\u003ch2\u003eCommon questions\u003c\/h2\u003e\n\u003cdiv class=\"aonsk-faq\"\u003e\n\u003cdetails\u003e\u003csummary\u003eWhen is Thessaloniki ready?\u003c\/summary\u003e\n\u003cp\u003ePlan around 60-69 Days.
