Large Red Cherry Tomato Seeds

Start Red Cherry Large Tomato seeds indoors 6–9 weeks before your last frost date, sowing 0.25 inch deep in moist seed-starting mix. Soil temperature needs to stay between 70–85°F for even germination. If your home runs cool, use a heat mat under the tray. Heirloom Large Red Cherry Tomatoes germinate in 7–10 days under the right temperature. Once the second set of true leaves appears, move seedlings into individual cells so roots have room to develop before transplant. Harden off transplants for about a week outdoors in a sheltered spot before planting them in the ground.

Large Red Cherry Tomato plants require full sun for 6-8 hours per day. Plant in loose, well-draining sandy loam with a pH of 6.2–6.8. If your ground is heavy clay, work in compost or perlite before planting. Water deeply and consistently, but let the top inch of soil dry between sessions. Fully dry ground followed by heavy soaking causes blossom rot and cracked fruit. Mulch the base to keep moisture stable and reduce watering.

Put the cage or trellis in at planting time. An indeterminate vine doesn't stop growing, so plants need support before they flop over the bed. Feed every 2–3 weeks once flowering starts with a balanced fertilizer, then  once fruit sets choose something lower in nitrogen. Pick fruits as soon as they're fully red and give slightly under pressure, however don’t leave ripe tomatoes on the vine for too long, as it slows new fruit development.
