The Oxheart tomato is an old heirloom from the 1920’s and is still very much as popular today as it was then. It is a heart shaped tomato that is pinkish red and very meaty with a mild sweet tomato flavor. Another very impressive tomato and one that we enjoy growing year after year. The tomatoes are huge weighing 280-454 g (10oz–1 lb) each. Sizes can vary significantly but it is safe to say that they get very large and they are very prolific.
Tomatoes are a warm-season crop that are easy to grow and provide delicious fruits for a variety of culinary uses. There are many varieties to choose from, ranging in size, shape, and color. Plant tomatoes in a location that receives full sun for at least 6 hours a day and has well-drained soil. Tomatoes prefer soil that is slightly acidic with a pH between 6.0 and 6.8. Start tomato seeds indoors 6-8 weeks before the last frost date in your area. Sow seeds 6mm (¼”) deep in seed-starting soil and keep them moist until they germinate, which should occur in 7-10 days. Once the seedlings have developed their second set of true leaves, transplant them into individual pots or into a larger container with at least 30cm (12”) of soil depth. When transplanting tomato seedlings into the garden, wait until after the last frost date and the soil has warmed up to at least 10°C (50°F). Dig a hole that is deep enough to cover the root ball and up to the first set of leaves. Space plants 60-90cm (24-36”) apart in rows that are 90-120cm (36-48”) apart. Fertilize tomato plants with a balanced fertilizer every 4-6 weeks during the growing season. Water the plants deeply once a week or more frequently if the weather is hot and dry. Tomatoes are susceptible to blossom end rot, which is caused by calcium deficiency, so consider adding calcium to the soil or using a calcium-rich fertilizer. Tomato plants need support to grow upright and to prevent the fruit from touching the ground, which can cause it to rot. Use stakes, cages, or trellises to support the plants as they grow.
Harvest tomatoes when they are fully ripe and have reached their mature size and color. The fruit should be firm but slightly soft to the touch.
