How to Grow Tomatoes from Seed: Cherry Tomatoes for Beginners

Growing tomatoes from seed opens up a world of varieties you simply can't find at a garden centre. The Honey Jar Red Striped cherry tomato is a perfect beginner's choice — sweet, prolific, crack-resistant, and beautiful on the vine with its distinctive red-and-yellow striped skin.

When to Start Tomato Seeds

Start indoors 6–8 weeks before your last frost date. Starting too early leads to large, root-bound transplants; starting too late means a shortened growing season. Most growers in zones 5–7 start seeds in late February through March.

Sowing Tomato Seeds

Fill seed cells or small pots with moist seed-starting mix. Sow seeds ¼ inch deep, 2 seeds per cell. Keep at 70–80°F (21–27°C) — bottom heat from a seedling heat mat significantly improves germination speed. Seeds germinate in 5–10 days.

Once seedlings emerge, remove the weaker of the two. Move immediately to strong light — 14–16 hours under grow lights or your sunniest windowsill. Leggy tomato seedlings (stretched toward light) are the most common beginner mistake.

Potting Up

When seedlings are 3–4 inches tall with their first true leaves, pot up to a 4-inch pot. Bury the stem up to the lowest leaves — tomatoes develop roots all along their buried stems, building a stronger plant.

Hardening Off and Transplanting

Two weeks before outdoor planting, begin hardening off: place seedlings outside in a sheltered spot for increasing periods each day. After 7–10 days they're ready for the garden. Transplant after last frost when soil has warmed to 60°F+. Space cherry tomatoes 24 inches apart. Bury deeply again — up to the first set of leaves.

Growing and Harvesting

  • Stake or cage immediately after transplanting
  • Water consistently — irregular watering causes blossom end rot and cracking
  • Fertilize every 2 weeks with a tomato-specific fertilizer once flowering begins
  • Harvest when fully coloured — cherry tomatoes at peak ripeness detach easily with a gentle twist

Frequently Asked Questions

How long do cherry tomatoes take from seed to harvest?

From seed sowing to first harvest is typically 70–80 days for cherry tomato varieties like Honey Jar. This includes 6–8 weeks of indoor growing plus 4–6 weeks of outdoor growth before the first ripe fruits appear.

Can I grow cherry tomatoes in containers?

Yes — cherry tomatoes are excellent container plants. Use a pot at least 15 gallons in size with drainage holes. Container tomatoes need more frequent watering and fertilizing than in-ground plants. Support with a stake or cage and they will produce abundantly all season.

Why are my tomato seedlings turning purple?

Purple colouring in tomato seedlings usually indicates phosphorus deficiency, often triggered by cold soil temperatures (below 55°F) that prevent root uptake. Move seedlings to a warmer location and ensure temperatures stay above 65°F. The discolouration typically resolves once plants warm up.
