"Bull's Heart" Tomato: How to Grow the Sweet Giant

The "Bull's Heart" variety is legendary: giant fruits weighing up to 500-800 grams, a heart-like shape, and meaty, sugary flesh. Being a late-maturing variety, it requires plenty of sun and very sturdy stakes, as the heavy crop can easily snap the branches.

Soil: The Foundation for a Record Harvest

Growing such large fruits requires a massive amount of nutrients. Tomatoes need loose, well-aerated soil.

• Best Choice: Fertile Loamy soils (Type 1).
• Soil Check: Perform the sausage test. A cracking ring (Type 1) is ideal. If the soil is too heavy (Clay, Type 3), the roots may suffocate, and the large fruits might crack from uneven moisture.

Best Companions (Good)

• Basil: Improves flavor and repels tomato hornworms.
• Carrots: Their roots aerate the soil, helping the tomato plants get more oxygen.
• Marigolds: Naturally kill soil nematodes that attack tomato roots.

Main Enemies and Hazards (Bad)

• Potatoes: The ultimate enemy. They share late blight. If potatoes get infected, your "Bull's Heart" crop will perish within days.
• Fennel: Releases growth-inhibiting toxins into the soil.
• Walnut Trees: The substance juglone from walnuts is lethal for tomato seedlings.
