How To Grow Kellogg’s Breakfast Tomatoes

Growing Kellogg’s Breakfast tomatoes is very much the same as growing other large vining heirloom tomatoes.

Kellogg’s Breakfast tomatoes can be grown at home from seed or can be purchased as potted seedling plants from a plant nursery. If growing from seed, purchase your Kellogg’s Breakfast tomato seeds in the winter or early spring and plant them indoors 6-8 weeks before the last frost in your area (usually this means sowing seeds indoors sometime in February-March). If available, an easier option is to buy Kellogg’s Breakfast seedling plants, although they are less common than many other heirloom tomatoes.

Whether you’re growing from seed or from purchased seedlings, don’t put them outdoors until threat of frost has passed. Tomato plants can be damaged at temperatures below 43°F (6°C). Read more about when to transplant tomatoes outdoors.

Kellogg's Breakfast Tomato Seedling Plant

Once outdoors, plant your Kellogg’s Breakfast tomato plants in nutrient-rich soil that drains water easily. These are large plants which should be spaced about 2 feet apart. They grow particularly well in raised garden beds and in large containers like wine barrel gardens. Put the large Kellogg’s Breakfast plants in a location where their leaves get direct sunlight for at least 6-8 hours per day. Also ensure they are close to a water spout so they will be watered frequently (a drip irrigation system is excellent for watering tomato plants).

Kellogg’s Breakfast tomato plants are indeterminate, meaning their vines keep growing longer and longer throughout the season. These larger vines require a significant trellis or cage structure to support them. Skip the small standard hardware store tomato cages and opt for a heavy-duty tomato cage, a sturdy vertical plant stake, a large garden obelisk, or even a metal garden arch. Use twine or plant ties to secure the vines to the support structure as they grow.

Tomatoes are heavy feeders (especially large beefsteak-types like Kellogg’s Breakfast) which can benefit from added nutrients when planted in containers or nutrient-deficient soil. Start by top-dressing soil with some homemade compost (or store-bought organic compost if you don’t have homemade). For an extra nutrient boost, try an one of these organic tomato fertilizer on your tomato plants:

How Tall Do Kellogg’s Breakfast Tomato Plants Get?

Kellogg’s Breakfast tomato plants are among the largest types of tomatoes to grow, with vines reaching 6-10 feet (or more). These vigorous plants grow largest when given a sturdy trellis structure to support the vines. Plant size can also be increased by planting them in a sunny location with nutrient-rich, well-draining soil and consistent watering.

Kellogg’s Breakfast tomato plants are indeterminate, meaning that the vines continue to grow longer (or taller if staked vertically) throughout the growing season. Unlike determinate tomatoes, they don’t reach a terminal mature height, and keep growing longer until the plant is killed by frost or cut back with pruners.

How Long For Kellogg’s Breakfast Tomatoes To Ripen?

Kellogg’s Breakfast Tomatoes take about 80 days to ripen after the seedling plants are transplanted out into the garden. Once the first tomatoes start to ripen (~80 days after transplanting outdoors), more tomatoes will continue to grow and ripen throughout the growing season until the plant is hit with a hard frost or cut back.

Harvesting Kellogg’s Breakfast Tomatoes

Kellogg’s Breakfast tomatoes are very large and take a long time to ripen on the vine. Some gardeners choose to leave some fruits on the vine to ripen to peak ripeness, so those fruits can be enjoyed fresh in the garden or harvested for fresh tomato toast. Extra fruits can be harvested/removed early and ripened indoors (at room temperature) as a form of insurance against hungry animals such as deer or birds who might get to your ripening tomatoes before you do!
