Minnesota gardeners know April can still bring snow, but cold-hardy vegetables planted now will be ready as soon as the ground thaws. If you are looking for the best vegetables to plant in april in minnesota, you have come to the right place. This guide will walk you through the top choices that can handle our unpredictable spring weather.
April in Minnesota is a tricky month. One day it is 50°F and sunny, the next you are shoveling slush. The key is to pick vegetables that laugh at frost and grow fast once the soil warms up. Let us get straight to the list.
Best Vegetables To Plant In April In Minnesota
These vegetables are your best bet for an early start. They can survive light freezes and even a dusting of snow. Plant them as soon as the soil is workable, which is usually mid to late April in southern Minnesota and early May up north.
Cold-Hardy Greens For Early April
Leafy greens are the champions of early spring. They thrive in cool soil and short days. Here are the top picks.
- Spinach: Plant seeds as soon as the ground thaws. Spinach germinates in soil as cold as 35°F. You will have baby leaves in about 30 days.
- Kale: This is a Minnesota superstar. It gets sweeter after a frost. Sow seeds directly in the garden in early April.
- Lettuce: Choose loose-leaf varieties like Black Seeded Simpson or Red Sails. They grow fast and you can harvest outer leaves for weeks.
- Arugula: Spicy and quick. It germinates in just 5 to 7 days. Plant a small patch every two weeks for a steady supply.
- Swiss Chard: Very cold tolerant. The colorful stems brighten up any garden bed. It will keep producing into summer if you pick the outer leaves.
Root Vegetables That Love Cool Soil
Root crops are perfect for April. They do not mind cold soil and they store well. Plant them early so they mature before the summer heat hits.
- Radishes: The fastest vegetable you can grow. Some varieties are ready in 22 days. Plant a row every week for continuous harvests.
- Carrots: Sow seeds directly in April. They take a while to germinate, so keep the soil moist. Choose short or round varieties like Parisian for heavy clay soil.
- Beets: Both the roots and greens are edible. Soak seeds overnight before planting to speed up germination. They tolerate light frost well.
- Turnips: An underrated choice for Minnesota. The roots are mild and the greens are delicious. Plant them in early April for a late May harvest.
- Potatoes: Plant seed potatoes in mid to late April. Cut them into chunks with at least two eyes each. They can handle a light freeze once sprouted.
Peas And Onions For Early Planting
These two crops are tradition in Minnesota gardens. They are some of the first things you can put in the ground.
Peas: Sow pea seeds directly in the soil as soon as it is dry enough to work. Snow peas, sugar snap peas, and shelling peas all work well. They actually prefer cool weather and stop producing once it gets hot. Plant them in a sunny spot with good drainage. Provide a trellis or netting for climbing varieties.
Onions: You have three options: sets, transplants, or seeds. Sets are the easiest for beginners. Plant them 1 inch deep and 4 inches apart in April. They can handle frost and will start growing right away. Green onions are even faster and you can harvest them in just a few weeks.
How To Prepare Your Garden For April Planting
Before you put any seeds in the ground, you need to get the soil ready. Minnesota clay can be heavy and wet in April. Follow these steps for the best results.
Check Soil Temperature
Do not just guess. Use a soil thermometer. Most cold-hardy vegetables need soil at least 40°F to germinate. Stick the thermometer 2 inches deep in the morning. If it is below 40°F, wait a few days.
Improve Drainage
Heavy clay soil holds water, which can rot seeds. Add compost or aged manure to your beds. This lightens the soil and adds nutrients. Raised beds are a great option if your soil stays soggy.
Use Row Covers
Floating row covers are cheap and effective. They protect plants from frost, wind, and pests. Drape them over hoops or directly on the plants. They let in light and water but keep the cold out. You can remove them when the weather stabilizes.
Start Seeds Indoors For Warm-Season Crops
While you are planting cold-hardy vegetables outside, start your warm-season seeds indoors. Tomatoes, peppers, and eggplants need a head start. Use seed-starting mix and grow lights. Transplant them outside after the last frost, which is usually mid to late May in Minnesota.
Common Mistakes When Planting In April
Even experienced gardeners make errors in April. Here are the biggest ones to avoid.
- Planting too early: If the soil is too wet, seeds rot. Wait until a handful of soil crumbles, not clumps.
- Planting too deep: Small seeds like lettuce and carrots need only a light covering. Read the seed packet for depth.
- Ignoring frost dates: Know your average last frost date. For the Twin Cities, it is around May 10. For northern Minnesota, it is late May.
- Overwatering: Cool soil holds moisture longer. Water only when the top inch of soil is dry.
- Forgetting to harden off transplants: If you started seeds indoors, introduce them to outside gradually. Put them out for a few hours each day for a week.
- Test your soil: Buy a cheap soil test kit. Add lime if the pH is below 6.0. Add sulfur if it is above 7.0. Most vegetables prefer a pH of 6.0 to 7.0.
- Clear the beds: Remove any weeds, rocks, or debris from last year. Rake the soil smooth.
- Add compost: Spread 1 to 2 inches of compost over the bed. Work it into the top 6 inches of soil.
- Mark your rows: Use string or a garden marker to keep rows straight. This helps you remember what you planted.
- Sow seeds: Follow the depth and spacing on the seed packet. Water gently after planting.
- Label everything: Use waterproof labels. You will forget what you planted by May.
- Cover with row covers: Secure the edges with soil or rocks. This keeps birds and frost away.
- Water as needed: Check soil moisture every few days. Do not let the seeds dry out.
- Succession planting: Plant a new row of radishes or lettuce every two weeks. This gives you a continuous harvest instead of one big glut.
- Interplanting: Plant fast-growing crops like radishes between slow ones like carrots. The radishes are ready before the carrots need the space.
- Use cold frames: A simple cold frame can extend your season by weeks. Build one from old windows or buy a kit.
- Choose bolt-resistant varieties: Some greens go to seed quickly in warm weather. Look for bolt-resistant labels on seed packets.
- Mulch after planting: A thin layer of straw or shredded leaves keeps soil temperature stable and reduces weeds.
