Top Plum Tomato Varieties for East Lyme Gardeners
Not all plum tomatoes perform equally well in Connecticut's humid summers and variable weather. Based on trials from the University of Connecticut Cooperative Extension Service, these varieties consistently deliver excellent results for East Lyme gardeners:

Planting Guide for East Lyme Gardeners
Successfully growing plum tomatoes in East Lyme requires understanding our specific microclimate challenges. Here's a step-by-step guide:
Soil Preparation (Late April)
East Lyme's soil tends to be clay-heavy with moderate drainage. Amend with 3-4 inches of compost and work into the top 12 inches of soil. Add crushed eggshells for calcium to prevent blossom end rot—a common issue in our humid climate. Test soil pH (ideal range: 6.2-6.8) through the UConn Soil Testing Lab.
Planting Timeline
- Indoors: Start seeds 6-8 weeks before last frost (early-mid March)
- Hardening Off: Begin 7-10 days before transplanting (mid-late April)
- Transplanting: After soil reaches 60°F (typically May 15-30)
Planting Technique
Bury seedlings deeper than their nursery pots—up to the first set of true leaves. This encourages stronger root development along the stem, crucial for withstanding East Lyme's occasional summer storms. Space plants 24-36 inches apart in rows 3-4 feet apart.
Support Systems
Plum tomatoes are determinate (bush-type) varieties that benefit from support:
- Cages: Use 5-6 foot tall cages for Roma and San Marzano varieties
- Stakes: Drive 7-foot stakes 6 inches from plant base
- Florida Weave: Ideal for multiple plants in a row
Managing Common East Lyme Tomato Challenges
Connecticut gardeners face specific challenges that require proactive management:
Humidity-Related Diseases
East Lyme's coastal humidity creates perfect conditions for fungal diseases. According to a 2023 survey by the New London County Master Gardeners, 68% of local tomato growers reported dealing with early blight:
East Lyme Tomato Grower Challenges (2023 Survey)
- 68% experienced early blight
- 42% dealt with blossom end rot
- 31% had issues with tomato hornworms
- 27% reported cracking fruit during heavy rains
Prevention Strategies
- Watering: Use drip irrigation or water at base in morning (never overhead)
- Spacing: Maintain adequate airflow between plants
- Mulching: Apply 3-4 inches of straw after soil warms
- Rotation: Don't plant tomatoes in same spot more than once every 3 years
Harvesting and Using Your East Lyme Plum Tomatoes
Plum tomatoes typically ripen from July through September in East Lyme. Harvest when fruits are uniformly colored and slightly soft to gentle pressure. For sauce-making, pick tomatoes at peak ripeness when sugar content is highest.
Local chef Maria Rodriguez of The Barn at Niantic recommends: "East Lyme's coastal climate produces plum tomatoes with exceptional flavor concentration. I use them in my signature tomato-basil bisque, featuring fresh basil from Gardner's Eden Nursery. The lower water content of plum varieties creates richer sauces without lengthy reduction time."
Extending Your Harvest
- Process tomatoes immediately after harvest for best flavor
- Freeze whole plum tomatoes (no need to peel)—they'll slip right out of skins when thawed
- Make sauce in batches and freeze in 2-cup portions
- Try dehydrating slices for tomato powder to use in winter dishes
