1. Planting Your Warm-Season Favorites

May is a prime month in the Midwest for planting warm-season crops now that the danger of frost has typically passed. Vegetables like tomatoes, peppers, cucumbers, beans, and corn can be sown directly or transplanted. Ensure your soil temperatures are consistently above 60°F (15°C) for optimal germination and growth. Proper soil preparation, including amending with compost, will give these summer staples a strong start. See more May planting tips for the Midwest.

2. Mastering May Weed Control Strategies

As your garden springs to life, so do the weeds! Early and consistent weed management in May is crucial to prevent them from outcompeting your desired plants for nutrients and light. Hand-pulling young weeds like dandelions and thistles before they set seed is effective. Applying a layer of organic mulch around your plants can also significantly suppress weed growth, retain soil moisture, and regulate soil temperature. For lawns, timely application of pre-emergent herbicides (if used) or focusing on cultural controls like proper mowing height can make a big difference. Learn comprehensive weed management techniques.

3. The Art of Companion Planting for a Healthier Garden

Unlock the synergistic power of plants by implementing companion planting strategies this May. Certain plant combinations can help deter pests, attract beneficial insects, improve soil health, and even enhance the flavor of your crops. For example, planting basil near tomatoes is said to repel tomato hornworms and improve tomato growth, while marigolds can deter nematodes and other pests. Researching beneficial pairings for your specific vegetable and flower choices can lead to a more resilient and productive garden. Explore companion planting combinations.

4. Essential May Lawn Care for a Lush Turf

A healthy lawn is the backdrop to a beautiful garden. In May, focus on proper mowing techniques – not cutting the grass too short helps it develop a stronger root system and outcompete weeds. Assess your lawn's fertilization needs; a light application might be beneficial if you plan to water throughout the summer, but avoid over-fertilizing which can promote weak growth. Address any bare spots by overseeding. Proper watering, deeply and less frequently, will encourage deep root growth, making your lawn more drought-tolerant.

5. Inviting Pollinators to Your Spring Garden

Pollinators like bees, butterflies, and hummingbirds are essential for a fruitful garden and a healthy ecosystem. Make your Midwest garden a haven for these vital creatures by planting a diverse array of nectar-rich flowers that bloom throughout the seasons. In spring, consider plants like Salvia, butterfly weed (Asclepias tuberosa), and early-blooming native perennials. Providing a small water source and avoiding pesticides will also help attract and protect these important garden visitors. Learn how to "bee" attractive to pollinators.

6. Smart Watering Strategies for Spring Growth

Consistent and appropriate watering is key, especially as young plants establish themselves in May. Aim to provide about an inch of water per week, either through rainfall or supplemental irrigation. It's generally best to water early in the day to minimize evaporation and allowfoliage to dry, reducing the risk of fungal diseases. Water deeply at the soil level to encourage strong root development, rather than light, frequent sprinklings that only wet the surface. Understand spring watering needs.
