Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings with cotyledons (seed leaves) emerge and develop first true leaves

Keep soil consistently moist but not waterlogged; provide 14-16 hours of bright light daily; maintain 70-75°F temperature

2

Vegetative

3-4 weeks

Plants develop multiple true leaves and sturdy stems; grows 6-12 inches tall indoors before transplanting

Harden off seedlings before transplanting; prune suckers if desired; fertilize every 2 weeks with balanced fertilizer

3

Flowering

2-3 weeks

Yellow flowers appear in clusters after plant is established in garden; Flare sets fruit prolifically

Ensure consistent watering and adequate phosphorus; avoid over-nitrogen which reduces fruiting; provide support structure if needed

4

Fruiting

3-4 weeks

Small green fruits develop and enlarge over time, gradually ripening to bright red; multiple clusters mature sequentially

Maintain steady watering and fertilize every 2-3 weeks; mulch around base to retain moisture; prune excessive foliage in heat to prevent fruit cracking

5

Harvest

Continuous throughout season

Fruits reach full red color and slight give when gently squeezed; peak sweetness and flavor

Pick regularly to encourage continued production; harvest in morning when cooler; leave stem attached when picking

Common Pests

  • Hand-pick; encourage parasitic wasps; use Bt (Bacillus thuringiensis) sprays

  • Spray with neem oil; increase humidity; remove heavily infested leaves

  • Yellow sticky traps; spray with insecticidal soap; encourage natural predators

  • Remove lower leaves; improve air circulation; apply copper fungicide; avoid overhead watering

  • Remove infected leaves; mulch to prevent soil splash; apply fungicide if severe

Uses

🍳

Fresh eating and snacking

Culinary

Flare cherry tomatoes are perfectly sized for snacking straight from the vine and adding whole to salads. Their concentrated sweetness and low acidity make them ideal for enjoying fresh with minimal preparation. [source]

🍳

Cooking and sauces

Culinary

The high sugar and low water content compared to slicing tomatoes makes Flare excellent for making concentrated pasta sauces, marinades, and roasted tomato preparations. Perfect for preserving as sauce or paste. [source]

🍳

Canning and preserving

Culinary

Flare's abundant, uniform harvest makes it ideal for canning whole, as paste, or sauce. The determinate growth ensures most fruit ripens simultaneously, allowing for efficient batch processing. [source]

💊

Lycopene source

Medicinal

Tomatoes contain lycopene, a powerful antioxidant associated with reduced cardiovascular disease risk and certain cancer prevention. Cooking tomatoes increases lycopene bioavailability. [source]

🦋

Pollinator support

Wildlife

Tomato flowers attract bees, hoverflies, and other beneficial insects essential for fruit set and garden pollination. Growing tomatoes supports pollinator populations. [source]

Harvest Tips

Harvest when fruits are fully red and slightly soft to squeeze; cherry tomatoes continue ripening after picking if left at room temperature; Flare's determinate nature means most fruit ripens within a 3-4 week window for concentrated harvesting, ideal for preserving and sauces

Fun Facts

  • 🌱 Flare was specifically bred for disease resistance and is known for its reliability even in challenging growing conditions, making it a favorite for both beginner and experienced gardeners
  • 🌱 Cherry tomatoes like Flare have higher sugar content per ounce than larger slicing tomatoes, which is why they taste sweeter despite being smaller
  • 🌱 Burying tomato transplants deeply (up to the first true leaves) stimulates additional root development along the buried stem, creating a stronger root system and more drought-resilient plants
