Early Spring Planting: What to Start First
Early spring is the ideal time for Minnesota gardeners to start their cool-season crops. As soon as the soil can be worked, typically around mid to late April, you can begin planting vegetables like peas, spinach, and onions, which are well-suited for the early growing season.
Peas thrive in cool weather and can be planted as soon as the soil temperature reaches about 40°F. They should be sown 1-2 inches deep and spaced 2 inches apart. Incorporate a trellis or support system for climbing varieties. Water the seeds lightly until they germinate, ensuring the soil remains consistently moist but not waterlogged.
Spinach is another fantastic crop for early spring. Plant seeds approximately ½ inch deep and 2 inches apart, as it also enjoys cooler temperatures and will often bolt if it becomes too hot. Keep the soil consistently moist; using a mulch can help retain moisture and suppress weeds during initial growth.
Onions, whether planted from sets or seeds, should be put in the ground around the same time as spinach and peas. Sets can be placed around 1 inch deep and spaced 4-6 inches apart. Water regularly, especially during dry spells, but be cautious not to overwater, as onions are susceptible to rot.
As these crops establish themselves, it’s important to protect them from late frosts. Covering them with row covers or cloth can provide the necessary insulation during unexpected cold snaps. Regular weeding and monitoring for pests will help ensure a successful early harvest. For additional planting tips and techniques, check out this resource to aid your gardening journey.
Transitioning to Warm-Weather Crops
As the Minnesota gardening season progresses into late spring, there comes a crucial transition from cool-season crops to warm-season varieties. By this time, frost risks have subsided, typically around the end of May, making it the right moment to introduce crops like tomatoes, peppers, and corn to your garden. These warm-weather crops thrive in the warmth of the soil and air, requiring consistent temperatures of at least 70°F for optimal growth.
One of the essential steps for successful gardening is hardening off seedlings before transplanting them into the garden. This acclimatization process helps young plants adjust to outdoor conditions, allowing them to develop sturdy structures. Start hardening off seedlings about a week before their intended transplant date. Gradually expose them to outdoor conditions by placing them in a sheltered location, increasing sun exposure and time outside daily. After seven days, when they are accustomed, they can be safely transplanted.
When it comes to transplanting, timing is critical. Aim to transplant seedlings in early to mid-June after the last frost date. For tomatoes and peppers, ensure that the soil has warmed appropriately, as they are sensitive to cold conditions. Dig holes slightly larger than the root ball of each seedling, adding nutrient-rich compost to promote vigorous growth. Space plants adequately to allow for their expansive growth. Regularly check on them in the initial days after transplanting to ensure they establish well.
