Minnesota’s short growing season demands tomato varieties that can ripen quickly before the first autumn frost arrives. Finding the best tomatoes to grow in minnesota means choosing cultivars that thrive in cool nights and unpredictable spring weather. You need plants that set fruit fast and resist common diseases like blight and septoria leaf spot.
This guide covers top-performing tomatoes for your Minnesota garden. We’ll look at determinate and indeterminate types, plus tips for getting a harvest before the frost hits. Whether you’re in Zone 3 or Zone 5, these picks will help you grow juicy, flavorful tomatoes.
Best Tomatoes To Grow In Minnesota
When you search for the best tomatoes to grow in minnesota, you’ll find dozens of options. But not all perform well here. The key is choosing varieties with short days to maturity—ideally under 75 days. Also look for cold tolerance and disease resistance. Here are the top contenders.
Early Season Varieties For Quick Harvests
Early tomatoes are your best bet for a reliable crop. They ripen in 55 to 65 days, giving you fruit before the weather turns.
- Sub Arctic Plenty – Matures in 50 days. Small, red fruits with classic tomato taste. Very cold tolerant.
- Glacier – Ripens in 55 days. Produces sweet, medium-sized tomatoes even in cool summers.
- Northern Delight – A compact plant that yields 3-inch fruits in 60 days. Good for containers.
- Stupice – Heirloom from Czechoslovakia. Ready in 60 days. Excellent flavor for early tomato.
These early varieties are determinate, meaning they grow to a fixed size and ripen all at once. Perfect for canning or freezing.
Mid-Season Tomatoes With Big Flavor
If you want larger, beefsteak-style tomatoes, mid-season picks work well. They need 70 to 80 days but offer superior taste.
- Brandywine – Heirloom with rich, sweet flavor. Takes 80 days but worth the wait. Grow in a warm spot.
- Cherokee Purple – Dark, smoky-sweet fruit. Matures in 75 days. Tolerates some cool weather.
- Amish Paste – Great for sauces. Oblong fruits ripen in 75 days. Very productive.
- Sun Gold – Cherry tomato with intense sweetness. Ready in 65 days. Prolific until frost.
Indeterminate varieties like Sun Gold keep producing until the first hard freeze. You’ll get a steady supply if you pick them regularly.
Cold-Tolerant Tomatoes For Northern Gardens
Minnesota nights can drop into the 40s even in July. Some tomatoes handle this better than others.
- Manitoba – Developed in Canada. Matures in 65 days. Resists cracking and cool temps.
- Prairie Fire – Small, red fruits in 60 days. Bred for short seasons.
- Oregon Spring – Sets fruit in cool conditions. Ready in 65 days. No staking needed.
- Moscow – Russian heirloom that thrives in cold. Produces 2-inch fruits in 60 days.
These varieties have been selected for their ability to set fruit when temperatures are below 55°F at night. They are essential for reliable harvests.
Disease-Resistant Hybrids
Fungal diseases are common in Minnesota’s humid summers. Hybrids with VFN resistance (Verticillium, Fusarium, Nematodes) are safer bets.
- Celebrity – All-purpose hybrid. Matures in 70 days. Resistant to many diseases.
- Big Beef – Large, flavorful fruits in 75 days. High resistance to blight.
- Early Girl – Reliable producer. Ready in 60 days. Tolerates cool soil.
- Mountain Merit – Resistant to late blight. Matures in 75 days. Great for organic gardens.
Disease resistance doesn’t guarantee a perfect crop, but it reduces risk. Rotate your tomato planting location each year to avoid soil-borne pathogens.
Cherry And Grape Tomatoes For Snacking
Small tomatoes ripen faster and are less prone to cracking. They are ideal for Minnesota’s climate.
- Sweet 100 – Classic cherry. Produces hundreds of fruits from 65 days onward.
- Yellow Pear – Heirloom with mild flavor. Ready in 70 days. Fun shape for salads.
- Black Cherry – Dark, sweet fruit. Matures in 70 days. Very productive.
- Tiny Tim – Dwarf plant for pots. Ready in 60 days. Good for kids.
Cherry tomatoes are indeterminate and will keep growing until frost. Pick them daily to encourage more production.
How To Choose The Right Variety For Your Garden
Selecting the best tomatoes to grow in minnesota depends on your specific conditions. Consider these factors before buying seeds or plants.
Days To Maturity
Check the seed packet for “days to maturity.” This is the time from transplanting to first ripe fruit. For Minnesota, aim for 75 days or less. Anything over 80 days is risky unless you use season extenders.
If you start seeds indoors 6-8 weeks before last frost, you can push the timeline. But outdoor planting usually happens after May 20 in southern Minnesota, later in the north.
Determinate Vs Indeterminate
Determinate tomatoes grow to a set height and ripen all at once. Good for canning or if you want a single big harvest. Indeterminate tomatoes keep growing and producing until frost. Better for fresh eating over a long period.
For Minnesota, many gardeners grow both types. Use determinate for processing and indeterminate for salads.
Space And Support
Indeterminate tomatoes need tall stakes or cages. Determinate types can be grown in smaller spaces or even containers. If you have limited room, choose compact varieties like Patio Princess or Bush Early Girl.
Raised beds warm up faster in spring, giving your tomatoes a head start. They also drain better, reducing disease risk.
Planting Tips For Minnesota Tomatoes
Even the best tomatoes to grow in minnesota won’t thrive without proper care. Follow these steps for a successful season.
Start Seeds Indoors
Begin seeds 6-8 weeks before your last frost date. For most of Minnesota, that’s mid-March to early April. Use a seed-starting mix and keep them under grow lights or in a sunny window.
Harden off seedlings gradually over a week before transplanting. Expose them to outdoor conditions for increasing periods each day.
Prepare The Soil
Tomatoes prefer slightly acidic soil with pH 6.0 to 6.8. Add compost or well-rotted manure a few weeks before planting. Work in a balanced fertilizer like 10-10-10.
Warm the soil by covering it with black plastic for two weeks before transplanting. This can speed up growth by several days.
Transplant At The Right Time
Wait until soil temperature reaches 60°F at 4 inches deep. In southern Minnesota, that’s usually late May. In the north, early June is safer.
Plant tomatoes deep—bury the stem up to the first set of leaves. Roots will form along the buried stem, creating a stronger plant.
Use Season Extenders
Wall O’ Water or cloches can protect plants from cold snaps. They also help you plant earlier. Floating row covers keep pests off and add a few degrees of warmth.
If frost threatens in September, cover plants with old sheets or blankets overnight. Uncover them in the morning.
Common Problems And Solutions
Even with the best tomatoes to grow in minnesota, issues can arise. Here’s how to handle them.
Blossom End Rot
This looks like a dark, leathery spot on the bottom of the fruit. It’s caused by calcium deficiency and inconsistent watering. Keep soil evenly moist and add calcium to the soil before planting.
Remove affected fruits to encourage new ones. Mulch around plants to retain moisture.
Late Blight
This fungal disease spreads fast in wet weather. Look for dark spots on leaves and white mold on stems. Remove infected plants immediately to prevent spread.
Prevent blight by spacing plants for good air circulation and watering at the base, not overhead. Use resistant varieties like Mountain Merit.
Catfacing
Deformed fruits with scars and holes are caused by cold weather during flowering. It’s cosmetic and doesn’t affect taste. Avoid planting too early in cold soil.
Catfacing is more common on large beefsteak varieties. Cherry tomatoes rarely have this issue.
Fruit Cracking
Sudden rain after dry weather causes tomatoes to swell and crack. Water consistently and mulch to reduce fluctuations. Pick fruits as soon as they ripen.
Some varieties like Manitoba are bred to resist cracking. Choose them if you have heavy clay soil that dries unevenly.
Harvesting And Storing Your Tomatoes
Knowing when to pick is key. Tomatoes ripen best on the vine, but you can harvest them when they show color and let them finish indoors.
When To Pick
Pick tomatoes when they are fully colored and slightly soft to the touch. For green tomatoes, harvest them before frost and store in a paper bag with an apple to speed ripening.
If frost is forecast, pick all mature green fruits. They will ripen over several weeks in a cool, dark place.
Storage Tips
Never refrigerate ripe tomatoes—it ruins texture and flavor. Store them at room temperature out of direct sun. Use within a week for best taste.
For long-term storage, freeze whole tomatoes or make sauce. Canning is also an option for determinate varieties that ripen all at once.
