Wyoming’s cold winters and short summers favor fast-maturing vegetables like peas and radishes. But if you are gardening in Wisconsin, you have a slightly longer growing season and more options. This guide covers the best fruits vegetables to grow in wisconsin for a productive garden.
Wisconsin’s climate is unique. You get cold winters, but warm summers with plenty of rain. The key is picking plants that can handle a late frost and ripen before the first fall freeze. Let’s get into the top choices for your garden.
Best Fruits Vegetables To Grow In Wisconsin
Wisconsin gardeners can grow a wide range of crops. The trick is matching plants to your specific zone. Most of the state is in zones 4b to 5b. This means you have about 130 to 150 frost-free days. Choose varieties that mature in that window.
Top Vegetables For Wisconsin Gardens
Vegetables are the backbone of most Wisconsin gardens. They grow quickly and provide fresh food all summer. Here are the most reliable options.
Cold-Hardy Greens
Greens love cool weather. You can plant them early in spring and again in late summer for a fall harvest. They are easy and fast.
- Spinach: Plant as soon as the soil can be worked. It bolts in heat, so harvest early.
- Kale: Very hardy. It actually tastes sweeter after a light frost.
- Lettuce: Choose loose-leaf varieties for continuous picking. Romaine works well too.
- Arugula: Grows fast. You can harvest baby leaves in just 3 weeks.
- Swiss Chard: Handles both cool and warm weather. It produces for months.
Root Vegetables
Root crops are perfect for Wisconsin’s soil. They store well and don’t need much fuss.
- Carrots: Grow best in loose, sandy soil. ‘Nantes’ and ‘Danvers’ types do well.
- Beets: Both the root and greens are edible. Plant every 3 weeks for a steady supply.
- Radishes: Ready in 25 days. Great for kids and early spring planting.
- Potatoes: A Wisconsin staple. Plant in early May for a fall harvest.
- Turnips: Grow fast. The roots are mild and the greens are tasty.
Warm-Season Vegetables
These need warm soil and full sun. Wait until after the last frost, usually mid-May.
- Tomatoes: Choose short-season varieties like ‘Early Girl’ or ‘Stupice’. Start seeds indoors.
- Peppers: Sweet bell peppers need heat. Use black plastic mulch to warm the soil.
- Cucumbers: Grow quickly. Trellis them to save space and improve air flow.
- Summer Squash: Zucchini and yellow squash are very productive. Two plants are enough.
- Green Beans: Bush beans are easier. Pole beans need a trellis but produce longer.
Cabbage Family Crops
Broccoli, cabbage, and cauliflower love cool weather. They are heavy feeders, so add compost.
- Broccoli: Harvest the main head before flowers open. Side shoots will follow.
- Cabbage: Stores well. ‘Stonehead’ is a reliable early variety.
- Cauliflower: Needs consistent moisture. Blanch the head by tying leaves over it.
- Brussels Sprouts: A long-season crop. They taste best after a frost.
Best Fruits For Wisconsin Gardens
Fruits take more patience than vegetables. But they are worth the wait. Perennial fruits come back year after year. Choose varieties that are disease-resistant and winter-hardy.
Strawberries
Strawberries are the most popular home fruit in Wisconsin. They are easy to grow in rows or containers.
- June-bearing: One big crop in early summer. ‘Honeoye’ and ‘Jewel’ are top choices.
- Everbearing: Produce smaller crops all season. ‘Ozark Beauty’ works well.
- Day-neutral: Fruit from summer to frost. ‘Tristar’ is reliable.
- Planting tips: Set plants in early spring. Remove first-year flowers for stronger plants.
Raspberries And Blackberries
Brambles grow well in Wisconsin. They need full sun and good air flow.
- Red Raspberries: ‘Heritage’ is a classic fall-bearing type. It fruits on new canes.
- Black Raspberries: More flavorful but less hardy. ‘Black Hawk’ is a good choice.
- Blackberries: ‘Illini Hardy’ can survive zone 5 winters. Provide a trellis.
- Care: Prune out old canes after fruiting. Mulch heavily for winter protection.
Apples
Apples are a Wisconsin tradition. But you need space for two trees for cross-pollination.
- Early varieties: ‘Zestar!’ and ‘Pristine’ ripen in August.
- Mid-season: ‘Honeycrisp’ and ‘McIntosh’ are popular. They store well.
- Late varieties: ‘Cortland’ and ‘Empire’ last into winter.
- Disease resistance: Look for scab-resistant types like ‘Liberty’ or ‘Enterprise’.
Grapes
Cold-hardy grapes are perfect for Wisconsin. They make great juice and jelly.
- Concord: The classic purple grape. Very hardy and productive.
- Marquette: A red wine grape that survives zone 4 winters.
- Frontenac: Another cold-hardy option. It resists diseases well.
- Planting: Put vines on a south-facing slope for extra warmth.
Other Fruits To Try
These less common fruits are well-suited to Wisconsin’s climate.
- Blueberries: Need acidic soil. Add peat moss or sulfur. ‘Northblue’ is a dwarf variety.
- Cherries: Sour cherries like ‘Montmorency’ are easier than sweet types.
- Plums: Japanese plums need protection. European plums like ‘Stanley’ are hardier.
- Pears: ‘Bartlett’ and ‘Kieffer’ can work. They need well-drained soil.
Planning Your Wisconsin Garden
Good planning makes gardening easier. Start with a simple layout. Consider your space, sunlight, and soil.
Choosing The Right Location
Most vegetables need 6 to 8 hours of direct sun daily. Fruits need full sun for best production.
- Pick a spot with good drainage. Avoid low areas where water pools.
- Protect plants from strong winds. A fence or building can help.
- Keep the garden close to a water source. Drip irrigation saves time.
Preparing The Soil
Wisconsin soil varies. Sandy soil drains fast. Clay soil holds water. Both need organic matter.
- Test your soil pH. Most vegetables like 6.0 to 7.0. Blueberries need 4.5 to 5.5.
- Add compost or well-rotted manure. Spread 2 to 3 inches over the bed.
- Work the soil to a depth of 8 to 10 inches. Remove rocks and weeds.
- Consider raised beds. They warm up faster in spring and improve drainage.
Timing Your Planting
Wisconsin’s last frost date is usually around May 10 to May 20. The first frost comes in late September or early October.
- Early spring: Plant peas, spinach, lettuce, and radishes as soon as soil is workable.
- Mid-spring: Plant potatoes, carrots, beets, and onions in April.
- Late spring: Plant tomatoes, peppers, and cucumbers after the last frost.
- Summer: Plant fall crops like broccoli, kale, and turnips in July.
Succession Planting
Get more from your garden by planting in waves. This keeps you harvesting all season.
- Plant a new row of beans every 2 weeks until mid-summer.
- Replace harvested lettuce with bush beans or beets.
- Use the same space for radishes after peas are done.
Caring For Your Garden
Once plants are in the ground, they need regular care. Water, weeds, and pests are the main challenges.
Watering Wisely
Most vegetables need 1 inch of water per week. Fruits need more during fruiting.
- Water deeply and less often. This encourages deep roots.
- Water in the morning. This reduces disease and evaporation.
- Use mulch to hold moisture. Straw, grass clippings, or wood chips work.
Managing Weeds
Weeds compete for water and nutrients. Stay on top of them.
- Pull weeds when they are small. Use a hoe for larger areas.
- Mulch around plants to block sunlight to weed seeds.
- Consider landscape fabric for permanent beds like strawberries.
Fertilizing
Wisconsin soils often need extra nutrients. Compost is the best all-around fertilizer.
- Side-dress tomatoes and peppers with a balanced fertilizer when they flower.
- Use a high-nitrogen fertilizer for leafy greens like kale and spinach.
- Avoid over-fertilizing. It can lead to lots of leaves but few fruits.
Pest And Disease Control
Common pests in Wisconsin include aphids, cabbage worms, and squash bugs. Watch for signs early.
- Use row covers to protect young plants from insects.
- Handpick large pests like tomato hornworms and squash bugs.
- Rotate crops each year to prevent soil-borne diseases.
- Choose disease-resistant varieties when possible.
Extending The Growing Season
Wisconsin’s short summer can be extended with simple tools. You can start earlier and harvest later.
Using Cold Frames
A cold frame is a box with a glass or plastic top. It traps heat and protects plants from frost.
- Place it over a garden bed in early spring. It can warm the soil by 10 degrees.
- Use it to harden off seedlings before transplanting.
- Extend fall harvest by covering cold-sensitive crops.
Floating Row Covers
These lightweight fabrics let light and water through. They add a few degrees of frost protection.
- Drape them over hoops or directly on plants.
- Remove them when plants start to flower for pollination.
- Use them to protect from insects like flea beetles.
Choosing Quick-Maturing Varieties
Look for seed packets with short days to maturity. This is critical for Wisconsin.
- Tomatoes: ‘Sub Arctic’ matures in 55 days.
- Corn: ‘Early Sunglow’ is ready in 65 days.
- Watermelon: ‘Sugar Baby’ needs 80 days.
- Pumpkins: ‘Small Sugar’ matures in 100 days.
Harvesting And Storing
Knowing when to harvest makes a big difference. Most vegetables taste best when picked at the right time.
Harvesting Tips
- Pick vegetables in the morning when they are crisp.
- Harvest leafy greens from the outside. The center keeps growing.
- Check tomatoes daily when they start to ripen. Pick them at first blush of color.
- Pull root vegetables when they reach the right size. Don’t let them get too large.
Storing Your Harvest
Proper storage keeps your food fresh longer. Different crops need different conditions.
- Root vegetables: Store in a cool, dark place like a basement or root cellar.
- Tomatoes: Keep at room temperature. Refrigeration ruins flavor.
- Greens: Wash and dry them. Store in a plastic bag in the fridge.
- Apples: Keep in a cool, humid place. Check for bad ones regularly.
Common Mistakes To Avoid
New gardeners often make the same errors. Here are a few to watch for.
- Planting too early. Cold soil can rot seeds and kill seedlings.
- Overcrowding. Plants need space for air flow and root growth.
- Ignoring soil health. Test and amend your soil every year.
- Forgetting to harden off transplants. Sudden sun and wind can shock them.
- Not mulching. Mulch saves water and reduces weeds.
