History & Nutrition

History

The Brandywine tomato has become the gold standard against which all heirloom tomatoes are measured, and its documented history stretches back to 1885 when it was first listed in the seed catalog of Johnson & Stokes of Philadelphia. The variety is believed to have originated with Amish farmers in Chester County, Pennsylvania, who named it after the Brandywine Creek that runs through the region. For nearly a century, Brandywine remained a regional treasure, passed down through generations of Pennsylvania Dutch families and small-scale seed savers who recognized its exceptional flavor. The variety nearly disappeared in the mid-20th century as commercial agriculture favored disease-resistant hybrids with longer shelf life over taste. Brandywine's rescue and subsequent fame is largely credited to seed saver Ben Quisenberry of Big Tomato Gardens in Ohio, who in the 1980s obtained seeds from Dorris Sudduth Hill, whose family had maintained the variety since the 1900s—hence the variety is sometimes called "Sudduth's Brandywine." The tomato's distinctive potato-leaf foliage (rather than the typical serrated tomato leaf) became a hallmark of authenticity. When the heirloom tomato movement exploded in the 1990s, Brandywine became its poster child, appearing in seed catalogs, farmers markets, and eventually upscale restaurants that celebrated its unparalleled taste.

Nutritional Benefits

  • High in lycopene
  • Excellent source of Vitamin C
  • Contains potassium
Climate & Temperature

Optimal Growing Temp

70°F - 85°F

Brandywine thrives at 70-85°F but is less heat-tolerant than modern hybrids. Fruit set suffers when nights exceed 75°F or days exceed 90°F. This heirloom performs best in moderate climates.

Survival Range

55°F - 90°F

Can survive these temperatures

tender
warm Season

Frost Note: Highly frost-sensitive. Protect from cold temperatures below 50°F. Brandywine is slower to mature than modern varieties, so start early indoors.

Best USDA Zones

Zone 5Zone 6Zone 7Zone 8

Humidity

40-60%

Moderate humidity preferred. Brandywine's potato-leaf foliage can trap moisture, increasing disease risk in humid climates.

Plant Size & Growth

Height

6-9 feet

Spread

2-3 feet

Growth Habit

indeterminate

annualRoot Depth: Deep, extensive root system reaching 3+ feet. Healthy roots are critical for supporting the large fruits this variety produces.
Growth Stages

Germination

7-14 days

Brandywine seeds may germinate slower and less uniformly than hybrid varieties. Maintain 75-85°F soil temperature for best results.

Seedling Stage

Duration: 5-6 weeks

True leaves: First true leaves show characteristic potato-leaf shape—broad, smooth edges unlike typical tomato foliage

Transplant ready: Ready when 6-8 inches tall with sturdy stem. Brandywine seedlings benefit from longer indoor growing period.

Vegetative Growth

Duration: 5-7 weeks after transplant

Vigorous growth phase. The distinctive potato-leaf foliage develops. Plants grow tall and require early staking. Larger leaves can make airflow a concern.

Flowering

Timing: 7-9 weeks after transplant

Duration: Continuous throughout season

Self-pollinating but can benefit from gentle shaking. Large flowers are attractive but can struggle in extreme heat.

Fruit Development

Begins: 4-6 weeks after flowering

Duration: Continuous until frost

Large fruits develop slowly—don't rush harvest. Allow 6-8 weeks from pollination to ripe fruit. First fruits often have characteristic cracks (cosmetic only).

Harvest Maturity

Timing: 80-100 days from transplant

  • Deep pink color throughout
  • Large size (1-2 pounds common)
  • Slight softness when gently pressed
  • Strong, sweet tomato aroma
  • Some natural cracking near stem is normal
Expected Yield

Per Plant

8-15 lbs per plant

Per Square Foot

3-6 lbs per square foot

Harvest Frequency

Every 4-7 days during production

Factors Affecting Yield

  • Lower yields than modern hybrids but exceptional flavor compensation
  • Heat stress significantly reduces fruit set
  • Consistent watering prevents cracking that reduces harvestable fruit
  • Disease management critical for sustained production
  • Proper pruning directs energy to fruit production
Watering Guide

Seedling Stage

Keep consistently moist

Established Plants

1-2 inches per week, deep and consistent

During Fruiting

Consistent moisture absolutely critical—Brandywine is famous for cracking

Preferred Method

Drip irrigation strongly recommended. Water at base only. Mulch heavily to maintain soil moisture.

⚠️ Critical Watering Periods

  • Flowering through harvest—entire fruit development

Pro Tips

  • CRITICAL: Brandywine cracks easily—maintain consistent soil moisture
  • Heavy mulching (4+ inches) helps prevent moisture fluctuations
  • Never let plants wilt then flood with water
  • Slightly reduce water during final ripening for better flavor
Fertilizing Guide

Container Growing
✓ Suitable for containers

Minimum Size

15 gallon minimum

Recommended Size

20+ gallon for best results

Depth Required

At least 18-24 inches deep

Best Varieties for Containers

Dwarf Brandywine varieties available but rare

Container Tips

  • Brandywine can grow in containers but needs exceptionally large pots
  • Heavy fruit requires very sturdy support system
  • Expect lower yields in containers than in-ground
  • Daily watering likely required in summer
  • Rich potting mix with added compost essential
Support & Trellising
Support Required

Support Type

Heavy-duty cage (6ft+), sturdy stake, or trellis system

Height Needed

7-8 feet tall minimum

When to Install

Install at transplanting—these plants grow tall quickly

Method

Single-stem training produces fewer but larger fruits. Cage growing allows 2-3 stems with good fruit production. Heavy fruit clusters may need individual support slings.

Tips

  • PRO TIP: Use concrete reinforcing wire cages—standard cages are too small
  • Plants can exceed 9 feet—plan support height accordingly
  • Heavy fruits (1-2 lbs each) need robust support to prevent breakage
  • Tie plants frequently as they grow—Brandywine vines are heavy
  • Consider A-frame or overhead trellis systems for maximum support

Pruning Guide
Pruning Recommended

Why Prune

Direct energy to fruit productionImprove air circulation through dense foliageReduce disease pressureEncourage larger fruits

When

Begin when plants are 12-18 inches, continue throughout season

How Often

Check and prune weekly

Technique

Remove suckers below first flower cluster. For larger fruits, remove more suckers and limit to 1-2 main stems. For more fruits, allow 3-4 stems.

Remove

  • All suckers below first flower cluster
  • Lower leaves as plant grows (especially touching soil)
  • Excessive suckers above first cluster (keep 2-4 maximum)
  • Yellow or diseased foliage promptly

Keep

  • Main stem(s)
  • 2-4 strong suckers above first flower cluster
  • Leaves shading developing fruit from sunscald
