Growing Information

Plant Type

Indeterminate heirloom tomato
(continues growing and producing until frost)

Mature Size

Height: 5–7 feet
Width: 2–3 feet

Light Requirements

Requires full sun for maximum fruit production and sweetness.

Soil Needs

Thrives in rich, well-draining soil with compost or organic matter added before planting.

Ideal soil pH: 6.2–6.8

Watering

Keep soil consistently moist but never soggy. Deep watering encourages stronger roots and healthier fruit.

Avoid overhead watering to help prevent disease.

Fertilizing

Feed every 2–3 weeks with a balanced tomato fertilizer once flowering begins.

Too much nitrogen may produce excess leaves with fewer tomatoes.

Planting Instructions

Starting Seeds Indoors

Start seeds indoors 6–8 weeks before your final frost date.

  • Plant seeds ¼ inch deep
  • Keep soil warm and moist
  • Germination usually occurs within 5–10 days

Provide strong light after sprouting to prevent leggy seedlings.

Transplanting Outdoors

Move outdoors only after danger of frost has passed and nighttime temperatures remain above 50°F.

When transplanting:

  • Bury stems deeply for stronger root growth
  • Add compost to planting hole
  • Water thoroughly after planting

Ongoing Care

Pruning

Remove lower leaves and small suckers to improve airflow and reduce disease pressure.

Mulching

Apply mulch around the base of plants to:

  • Retain moisture
  • Suppress weeds
  • Reduce soil splash onto leaves

Support

Because fruits grow extremely large and heavy, sturdy cages or stakes are essential.

Tie branches loosely as plants grow.

Harvesting

Kellogg’s Breakfast tomatoes are ready when fruits develop a rich golden-orange color and slightly soften when gently squeezed.

Harvest regularly to encourage continued production.

These tomatoes are prized for:

  • Sweet, fruity flavor
  • Smooth texture
  • Low acidity
  • Huge slicing size

Common Problems

Cracking

Usually caused by uneven watering. Maintain consistent soil moisture.

Blossom End Rot

Often linked to inconsistent watering or calcium imbalance.

Hornworms

Inspect plants regularly and remove pests by hand if found.

Early Blight

Improve airflow and avoid wetting foliage to help prevent fungal issues.

Companion Plants

Great companions include:

  • Basil
  • Marigolds
