Jung Seed Wisconsin 55 Tomato

Semi-determinate plants grow to a manageable, compact size but continue to produce fruit over a longer period than strictly determinate varieties. They offer the best of both worlds: a heavy initial harvest followed by continued production until the first frost.

Yes, Wisconsin 55 is an excellent choice for canning. The fruits have solid flesh and strong skins, which hold up well during processing, and their classic flavor profile makes them a reliable staple for sauces and preserves.

You should space your plants 24 to 30 inches apart. This spacing ensures adequate airflow, which is critical for preventing the diseases this variety is bred to resist, such as early blight and leaf spot.

While Wisconsin 55 is adaptable, it is specifically optimized for growing zones 3 through 9. If you are outside this range, you may struggle with extreme heat or a growing season that is too short to reach the 75-day maturity mark.

Even though they are semi-determinate, these plants are vigorous and will benefit from support. Using a cage or stake will keep the fruit off the ground, which helps prevent rot and makes harvesting much easier.

Wisconsin 55 is bred to have a robust root system and efficient nutrient uptake, which helps the plant manage calcium levels effectively. While this genetic resistance is strong, consistent watering is still the best way to prevent blossom-end rot in any tomato variety.
