Growth Stages

1

Seedling

2-3 weeks

Small plants with 2-4 true leaves, delicate and light green

Keep soil consistently moist but not waterlogged; provide 14-16 hours of bright light daily; maintain 65-75°F temperature; thin seedlings to prevent crowding

2

Vegetative

3-4 weeks after transplanting

Bushy, compact growth with multiple stems and dark green foliage; plant reaches 2-3 feet tall (determinate habit)

Transplant into larger containers as needed; harden off before outdoor planting; stake or cage early; reduce nitrogen to encourage flowering; maintain consistent watering

3

Flowering

2-3 weeks

Yellow flowers appear in clusters; plant reaches full determinately compact size with dense foliage

Maintain consistent watering and nutrient levels; apply mulch around base; reduce excess nitrogen; support developing clusters with stakes; ensure adequate calcium availability

4

Fruiting

4-5 weeks

Marble-sized green fruits appear and enlarge; medium-sized paste tomatoes form, turning orange-red as they mature

Continue consistent watering; prune excess foliage only if shading fruit; apply calcium amendment if not already done; monitor for pests; support heavy fruit clusters

5

Harvest

2-4 weeks of peak harvest

Fruits are firm, fully colored orange-red, and slightly yield to gentle pressure; heavy production on compact determinate plant

Harvest ripe fruit daily for best flavor; use for sauce, paste, or fresh eating; remove plant after final harvest; save seeds if desired

Common Pests

  • Hand-pick large caterpillars; monitor plants daily; use Bt (Bacillus thuringiensis) for smaller infestations; allow parasitic wasps

  • Spray with strong water stream; use insecticidal soap; introduce ladybugs; neem oil as last resort

  • Yellow sticky traps; insecticidal soap; reflective mulches; neem oil; maintain good air circulation

  • Remove infected lower leaves; improve air circulation; avoid overhead watering; mulch to prevent soil splash; fungicide if severe

  • Remove infected plant parts immediately; copper fungicide; improve air circulation; avoid overhead watering; plant resistant varieties

Uses

🍳

Tomato sauce and paste

Culinary

Kenora Sunset is a paste variety specifically bred for processing, with high solids content and low water content. Excellent for making homemade tomato sauce, paste, and canned products. [source]

🍳

Fresh eating and salads

Culinary

Despite being a paste variety, Kenora Sunset has excellent flavor and can be enjoyed fresh in salads, on sandwiches, or sliced with salt and pepper. [source]

🏠

Cold climate gardening

Household

Bred in Canada for northern zones, this variety requires fewer heat days than standard tomatoes, making it ideal for gardeners in zones 3-5 or short-season regions. [source]

🍳

Canning and preservation

Culinary

High pectin and acidity make Kenora Sunset ideal for home canning, salsa, and long-term food storage without additional pectin. [source]

🦋

Pollinator attraction

Wildlife

Tomato flowers attract bees and other beneficial insects, supporting garden biodiversity while improving fruit set through pollination. [source]

Harvest Tips

Pick fruits when fully colored orange-red and slightly soft to touch; Kenora Sunset ripens reliably on the vine; harvest regularly to encourage continued production; determinate varieties produce most fruit simultaneously, ideal for sauce-making; tomatoes can be picked at breaker stage (first blush of color) and ripened indoors if needed

Fun Facts

  • 🌱 Kenora Sunset was developed at Agriculture and Agri-Food Canada's research center and is named after Kenora, Ontario, reflecting its cold-hardy heritage
  • 🌱 As a determinate variety, all fruits mature within a narrow window, making it perfect for single-harvest processing rather than continuous fresh eating
  • 🌱 Tomato plants can be propagated from cuttings as easily as from seeds—cut a healthy stem below a leaf node, place in water until roots develop, then plant
