Getting your garden beds ready for the growing season is essential for a successful and thriving garden. Here are some helpful tips to get you started this season:
Prepare Your Garden Beds
- Clear out any remaining debris and weeds from existing or planned garden beds.
- Amend the soil with compost or organic matter to improve fertility and structure for your plants.
- Level the soil and remove any rocks or clumps in the garden bed.
Plant Cool-Season Vegetables
Early May is an ideal time to kickstart your garden by planting a variety of cool-season crops that thrive in the cooler temperatures of spring. These resilient and nutritious vegetables not only tolerate the lingering chill but also provide a delicious harvest that can be enjoyed in salads, soups, and stir-fries.
- Lettuce, spinach, kale, radishes, and peas are among the top choices for early spring planting in Minnesota, offering gardeners a diverse array of flavors and textures to enjoy throughout the season.
- Consider using row covers or cloches to protect young plants from potential late frosts.

Transplant Seedlings
Transplanting seedlings of warm-season vegetables like tomatoes, peppers, and eggplants is an exciting milestone in the gardening calendar, signaling the transition to summer crops once the risk of frost has passed in May.
- Transplant seedlings of warm-season vegetables like tomatoes, peppers, and eggplants after the risk of frost has passed.
- Harden off seedlings by gradually exposing them to outdoor conditions for 7 to 10 days before transplanting. Place seedlings outdoors in a sheltered location for a few hours each day, gradually increasing exposure to sunlight and outdoor elements over time.
Sow Annual Flowers and Herbs
Direct sowing seeds of annual flowers such as marigolds, zinnias, cosmos, and sunflowers is a delightful way to add vibrant colors, textures, and pollinator-friendly blooms to your garden during the spring and summer months. These easy-to-grow flowers thrive when planted directly in well-prepared garden beds or containers, offering a rewarding experience for gardeners of all skill levels.
- Direct sow seeds of annual flowers like marigolds, zinnias, cosmos, and sunflowers.
- Plant herbs such as basil, cilantro, dill, and parsley in garden beds or containers.
Divide and Transplant Perennials
Dividing overcrowded perennial plants such as hostas, daylilies, and irises is an essential garden task that promotes plant health, encourages vigorous growth, and allows you to propagate new plants for expansion or sharing with fellow gardeners. Over time, clumps of perennials can become congested, leading to reduced flowering, diminished vigor, and increased susceptibility to pests and diseases. Dividing these plants helps rejuvenate them by providing more space for healthy root development and promoting overall garden aesthetics.
- Replant divisions in new areas of the garden or share with friends and neighbors.

Mulch and Weed Control
Applying a layer of organic mulch around plants is a beneficial gardening practice that provides numerous advantages for plant health, soil fertility, and overall garden maintenance. Organic mulches such as shredded bark, straw, leaves, or compost offer a natural and environmentally friendly way to improve soil structure, conserve moisture, regulate soil temperature, and reduce weed competition.
- Stay on top of weed control by hand-pulling or using mulch or landscape fabric to minimize weed competition.
Prune Spring-Blooming Shrubs
Pruning early spring-blooming shrubs like lilacs and forsythias is an important gardening task that helps maintain plant health, control size, and promote vigorous growth and abundant flowering in future seasons. These shrubs bloom on old wood, meaning they produce flowers on growth from the previous year. Pruning them right after they finish flowering allows you to shape the plants, remove dead or damaged wood, and encourage new growth for the next year’s blooms.
Monitor Watering Needs
Watering newly planted seedlings, transplants, and container-grown plants is crucial for their establishment and survival, particularly during periods of dry weather or when plants are in active growth. Proper watering ensures that plants receive the moisture they need to develop healthy root systems, maintain turgor pressure in their cells, and support essential physiological functions.
- Water deeply and infrequently to encourage deep root growth.
Inspect for Pests and Diseases
Keeping a vigilant watch for signs of pests and diseases in your garden is essential for maintaining plant health, preventing damage, and addressing issues promptly before they escalate. Pests such as aphids, caterpillars, and fungal diseases can quickly infest and spread throughout your garden, affecting the growth and vitality of plants.
- Take proactive measures such as handpicking pests, applying organic sprays, or using beneficial insects for control.

Set Up Support Structures
Installing supports such as trellises, stakes, or cages for climbing plants like peas, beans, and cucumbers is a practical and beneficial gardening practice that helps maximize space, promote healthy growth, and improve overall yield. These vining vegetables require support as they grow upward, reducing the risk of disease, minimizing pest damage, and making harvesting easier.
- Tie up or train vines to encourage upward growth and prevent sprawling.
Fertilize as Needed
Applying balanced organic fertilizer or compost to garden beds is a fundamental practice that promotes soil fertility, supports healthy plant growth, and enhances overall garden productivity. Organic fertilizers and compost provide essential nutrients in a slow-release form, improving soil structure, encouraging beneficial microbial activity, and minimizing environmental impact compared to synthetic chemical fertilizers.
- Follow specific recommendations based on soil test results or plant requirements.
Plan for Pollinator Gardens
Designate a section of the garden for pollinator-friendly plants such as bee balm, coneflowers, salvia, and milkweed to attract beneficial insects.
Remember to adjust this checklist based on your specific garden conditions and preferences. May is an exciting time to be in the garden, so enjoy the process of nurturing plants and watching your garden come to life during this beautiful spring season in Minnesota!
