Lycopersicon esculentum
TOMATO-OXHEART-RED is an old favorite! This large, fleshy, delicious and juicy variety of tomato matures mid-season with smooth firm fruit. They can weigh around 500grmas so require staking and are perfect for adding to your favourite recipes.  Oxheart Tomatoes are typically larger than other varieties, with a heart-shaped appearance and a deep red colour.  They grow well in light or heavy soils but you will obtain better results if you add organic matter, some pre-planting fertilizer and the chosen site has good drainage.

Sow in a good mix of soil and lightly cover – keep moist but not wet. Transplant when seedlings achieve 3-4 leaves.

Oxheart Red Tomato is often know as old-fashioned “Bullock Heart”  if you’re in Queensland, or “Ox Heart” in other parts of Australia

How to Grow Oxheart-Red Tomatoes

Here’s a guide on how to grow Oxheart-Red Tomatoes.

  • Choose a location that receives at least six hours of direct sunlight every day.   Tomatoes need warm weather to grow and thrive. Ideally plant them in an area that is protected from strong winds. Also, ensure that the soil is well-draining, rich in nutrients, and has a pH level of 6.0 to 6.8.
  • Prepare your soil so it’s fertility can grow and produce healthy fruit.  Add organic matter such as compost or well-rotted manure to improve  texture and fertility.  Work the organic matter into the top 30 cm (12 inches) of soil to distribute the nutrients are evenly.
  • Plant the tomato seedlings after the last frost date in your area.  Space the plants 60-90 cm (24-36 inches) apart in rows that are 90-120 cm (36-48 inches) apart. Dig a hole that is slightly deeper than the root ball of the seedling and mix in some slow-release fertiliser.  Place the seedling in the hole and fill the hole with soil. Firmly press the soil around the base of the plant and water well.  Or sow direct in warm climates.
  • Water and fertilize regularly as tomatoes need consistent moisture to grow and produce fruit. Deeply water once a week, making sure the water penetrates the soil to a depth of at least 30 cm (12 inches). Avoid overhead watering, as this can lead to fungal diseases.  Fertilise the plants every two weeks with a balanced fertiliser, following the instructions on the package.
  • Mulching around the base of the plants can help conserve moisture, suppress weeds, and regulate soil temperature. Apply a layer of organic mulch such as straw or shredded leaves around the plants, being careful not to cover the stem.
  • Provide support for the plants as the oxheart-red tomato plants grow taller, they will need support to keep them from falling over.  Stake the plants or use a tomato cage to provide support. Be sure to provide support early in the growing season, as it will be harder to do once the plants have grown larger.
  • Watch for pests and diseases as tomatoes are susceptible to many pests and diseases such as aphids, whiteflies, and blight. Keep an eye on your plants for signs of trouble and take action as soon as possible to prevent the spread of disease. Use organic pest control methods whenever possible, such as insecticidal soap or neem oil.
  • Harvest the tomatoes at about 80-90 days when they have matured and have a deep red colour. Gently twist the tomatoes off the vine, or use pruning shears to cut them off. Store the tomatoes at room temperature until they are fully ripe, then use or refrigerate them.
  • Growing oxheart-red tomatoes can be a fun and rewarding experience. By following these tips, you can produce a bountiful harvest of delicious, juicy tomatoes that will add flavour and colour to your meals.

Red Oxheart Tomato is an indeterminate plant.  Indeterminate tomato plants continue to grow and produce fruit throughout the growing season until they are killed by frost or disease. They require staking or trellising to support their vining growth habit.  In contrast, determinate tomato plants grow to a certain size and produce fruit for a shorter period of time, usually ripening all their fruit at once.

Heritage of Oxheart Red Tomato

The Red Oxheart tomato is an heirloom tomato variety believed to have originated in Europe, possibly in Russia or Italy. The exact origins of the variety are uncertain, as there are multiple tomato varieties with similar names and characteristics.

Generations of gardeners and farmers have grown Oxheart Red Tomato.  It is one of the classic heirloom tomato varieties. Commonly used for canning, sauces, and slicing for sandwiches and salads.
