Tomato Heartbreakers F1

Tomato Heartbreakers F1 Seeds

(Heart-Shaped Cocktail Tomato)

Tomato Heartbreakers F1 is a signature series from PRUDAC — a specialist breeder focused on compact, ornamental-productive patio tomatoes. The Heartbreakers series is built around one defining characteristic: all varieties produce heart-shaped cocktail tomatoes, a fruit shape that is immediately distinctive and visually charming both on the plant and on the plate.

The heart shape is visible when the fruit is whole and becomes a perfect symmetrical heart when cut in half crosswise — making Heartbreakers tomatoes a popular choice for food presentation, garnishing, salads, and snacking. The fruit has a juicy texture with tender skin and delivers a well-balanced sweet-sour flavor profile with a Brix rating of approximately 8–9, indicating good natural sugar content for a cocktail tomato.

The Heartbreakers series includes multiple compact varieties suited to different container sizes and growing preferences. Each model in the Heartbreakers series has excellent vigor and shows an abundance of fruit, with a crop time from young plant to ripe red fruit of 10–12 weeks. Plants are bred for regrowth after the first harvest — provided ripe fruits are harvested promptly, plants continue to set new trusses and produce across an extended season.

The series requires no pruning, making it exceptionally easy to manage for home gardeners and patio growers. Compact plant habit, sturdy leaves, and strong disease tolerance make Heartbreakers F1 a reliable and productive choice across diverse growing conditions including Gulf weather.

In Gulf conditions, Heartbreakers F1 tomatoes perform as a warm-season crop, suitable for protected cultivation or cool-season outdoor growing from autumn through spring

Growing Tips

• Sow Heartbreakers F1 seeds indoors 6–8 weeks before intended transplanting date.
• Sow on the surface of a good, free-draining, moist seed-starting mix and cover with a fine layer of compost or vermiculite.
• Maintain a consistent temperature of 15–20°C until germination, which takes 7–14 days.
• When seedlings develop 2 true leaves, transplant into individual 7.5 cm pots and grow on at a minimum temperature of 15°C in a bright, sunny position.
• Once plants reach approximately 20 cm height, transplant into their final 15–20 cm containers using a quality, fertile potting mix.
• Heartbreakers F1 requires no pruning or pinching — the compact branching habit manages itself throughout the season.
• Position plants in full sun for best fruit production and flavor development.
• Water consistently, keeping soil evenly moist but not waterlogged — irregular watering causes blossom end rot and fruit cracking.
• Feed weekly with a balanced tomato fertilizer once flowering begins, switching to a higher-potassium formula once fruits start to set.
• Harvest fruits promptly as they ripen to encourage the plant to continue producing new trusses.
• Heartbreakers F1 is specifically bred for regrowth after harvest — plants that have ripe unharvested fruit will slow or stop setting new flowers.
• In Gulf conditions, autumn sowing (August–September) for transplanting in October–November delivers the best cool-season outdoor crop.
• Protected growing under shade cloth or indoors extends the productive season in warmer months.
