‘Wisconsin 55’ Tomato, organic seeds (Solanum lycopersicum) This classic heirloom tomato was developed by the University of Wisconsin for a relatively early harvest and solid performance in cooler climates and shorter growing seasons. It produces medium-to-large, smooth, round red fruit. Mild, slightly tangy flavour suits slicing, canning, and sauces. Gaia also highlights crack resistance. The packet contains approximately 25 open-pollinated organic seeds certified by Ecocert Canada, lot GO24010, with reported germination above 85%. Consistent moisture and sturdy support help gardeners obtain an even, accessible harvest from this historic variety today.

Start seeds indoors 6 to 8 weeks before transplanting, approximately 1/8 to 1/4 inch deep. Gaia lists germination in 5 to 10 days from 21 to 32°C, with an optimum of 23 to 29°C. Provide bright light immediately after emergence. During hardening off, reduce watering and nitrogen gradually without allowing plants to wilt. Transplant after all frost risk has passed into warm, fertile, well-drained soil with 24 to 36 inches of spacing. Install a cage or stake at planting to support stems and preserve good airflow. Water the mix evenly during establishment.

Gaia lists 70 to 80 days to maturity, a height of 4 to 6 feet, and a spread of 24 to 36 inches. Growth habit is contradictory in the source: one sentence calls the plant determinate, while the label and the same description also state indeterminate. This page therefore keeps the uncertainty explicit. Water deeply at soil level and harvest after fruit becomes fully red. A tomato that has begun to blush can finish ripening off the vine above 21°C. Ripe fruit is edible, but keep leaves, stems, and green tomatoes away from pets.

Uses in the garden

Grow Wisconsin 55 in full sun in a warm, fertile, well-drained plot. Preserve 24 to 36 inches between plants so light and air can circulate. Place plants north of shorter crops so their 4-to-6-foot height does not shade them. Install a large cage at transplanting because Gaia provides conflicting determinate and indeterminate growth-habit statements. Water deeply at soil level and mulch after the soil warms to stabilize moisture. Label the support Wisconsin 55 and lot GO24010. Wisconsin 55 is a classic heirloom tomato developed by the University of Wisconsin for shorter seasons and cooler climates. It produces medium-to-large, smooth, round red fruit with mild, slightly tangy flavour. Fruit suits slicing, canning, and homemade sauces. Gaia describes good crack resistance and a relatively early harvest. Gaia calls the plant determinate in one sentence, but the label and the same description also state indeterminate. This growth-habit conflict remains disclosed so an uncertain value is not presented as one settled fact. Gaia lists a height of 4 to 6 feet, a spread of 24 to 36 inches, and 70 to 80 days to maturity. Lot GO24010 contains approximately 25 open-pollinated organic seeds with reported germination above 85%.

01 How many Wisconsin 55 tomato seeds are in the packet?

The Gaia packet contains approximately 25 Wisconsin 55 tomato seeds certified organic by Ecocert Canada. Lot GO24010 reports germination above 85%. Gaia identifies this garden crop as annual, heirloom, and open-pollinated. Because the quantity is approximate, a small variation may occur.

Keep the packet with seedlings so the cultivar and lot remain identified. Wisconsin 55 is a classic heirloom tomato developed by the University of Wisconsin for shorter seasons and cooler climates.

02 How should Wisconsin 55 tomato seeds be started?

Start seeds indoors 6 to 8 weeks before transplanting, approximately 1/8 to 1/4 inch deep in clean, moist seed-starting mix. Gaia lists germination in 5 to 10 days from 21 to 32°C, with an optimum of 23 to 29°C. Keep the mix moist without standing water and provide bright light immediately after emergence. During hardening off, reduce watering and nitrogen gradually without allowing plants to wilt. Transplant only after frost risk has passed and the soil has warmed. Space plants 24 to 36 inches apart and install a large cage immediately. Wisconsin 55 is a classic heirloom tomato developed by the University of Wisconsin for shorter seasons and cooler climates.

03 How long does Wisconsin 55 germination take?

Gaia lists germination in 5 to 10 days from 21 to 32°C, with an optimum of 23 to 29°C. Lot GO24010 reports a rate above 85%, without guaranteeing every seed under all conditions. Use clean, light seed-starting mix, maintain consistent moisture without saturation, and provide bright light immediately after emergence. During hardening off, reduce water and nitrogen gradually without allowing plants to wilt. Label the container Wisconsin 55 clearly so this heirloom tomato remains separate from other varieties. Wisconsin 55 is a classic heirloom tomato developed by the University of Wisconsin for shorter seasons and cooler climates. It produces medium-to-large, smooth, round red fruit with mild, slightly tangy flavour.

04 How much space and support does Wisconsin 55 need?

Allow 24 to 36 inches between plants and install a sturdy cage at transplanting. Gaia lists a height of 4 to 6 feet and a spread of 24 to 36 inches. Growth habit conflicts in the source: one sentence calls Wisconsin 55 determinate, while the label and the same description state indeterminate. A large cage covers both possibilities without restricting the plant. Place it in full sun, preferably north of shorter crops. Tie stems with soft material and maintain consistent moisture. Wisconsin 55 is a classic heirloom tomato developed by the University of Wisconsin for shorter seasons and cooler climates.

05 When should Wisconsin 55 tomatoes be harvested?

Harvest after round fruit becomes fully red. Gaia lists 70 to 80 days to maturity. A green tomato whose colour has begun to blush can finish ripening off the vine above 21°C. Arrange fruit in one layer, inspect it often, and pick fruit that has begun changing colour before the first frost. Use ripe tomatoes promptly for slicing, canning, or sauce. Store whole fruit from 12 to 21°C as listed by Gaia and refrigerate cut portions in a covered container.
