The month of May marks the turning point between spring and summer and brings longer days and warmer temperatures. For gardeners, this means new tasks to complete. While some plants happily settle in by themselves, others require extra care to flourish. To keep your May garden thriving, focus on key tasks that can lead to a successful growing season.
Your Essential May Garden To-Do List
It’s easy to feel overwhelmed when there are so many things happening in the garden. But don’t worry, though. This list will help you stay on track. Here’s a list of what you should focus on.
1. Plant Warm-Season Crops Before It’s Too Late
Early May is the best time to establish heat-loving vegetables like tomatoes, peppers, and squash as these plants need warm soil and consistent moisture. In cooler zones, row covers can help maintain soil warmth. In hotter climates, provide some afternoon shade to prevent stress from excessive heat.
Checklist:
✔ Direct sow beans, melons, and corn after the last frost date.
✔ Transplant tomatoes, peppers, and eggplants into nutrient-rich soil.
✔ Apply mulch to conserve moisture and reduce weeds.
It’s important to remember that warm-season crops need time to establish themselves before the hottest months take hold. Don’t wait too long to plant them!
2. Feed Perennials to Encourage Strong Growth
Perennials push for new growth in May but will need the right nutrients to sustain their energy. A slow-release fertilizer boosts flowering plants while organic compost enriches soil naturally. Use a specialized fertilizer to enhance bloom production for acid-loving shrubs like azaleas.
Checklist:
✔ Apply compost or organic fertilizer around perennials.
✔ Deadhead early bloomers to encourage continuous flowering.
✔ Divide overcrowded perennials like hostas and irises to promote healthier growth.

3. Stay Ahead of Weeds Before They Take Over
It’s no surprise that weeds thrive in May, as they spread quickly with rising temperatures and increased sunlight. Left unchecked, they’ll compete with your plants for water and nutrients. The best approach to prevent weeds from winning is early intervention. Removing them before they mature reduces their ability to reseed.
Checklist:
✔ Pull weeds by hand after rain for easier removal.
✔ Add a 2-3 inch layer of mulch to garden beds.
✔ Use a hoe or weeding tool to break up young weeds before they mature.
4. Watch for Pests and Diseases
As the temperature rises, insect activity also increases. Aphids, slugs, and fungal diseases become more common. Early detection can prevent these infestations from worsening.
Checklist:
✔ Inspect leaves for aphids, spider mites, and caterpillar eggs.
✔ Remove diseased foliage before the problem spreads.
✔ Encourage beneficial insects like ladybugs and lacewings by planting native flowers.
Act fast once you spot early signs of pests. Natural remedies like neem oil or insecticidal soap work well in controlling the spread of many common garden pests.
5. Adjust Your Watering Routine
The arrival of Summer means declining Spring rains. As such, it’s essential to adjust your garden’s watering habits to encourage strong root systems. Meanwhile, morning watering limits the chances of evaporation and prevents fungal issues. On the other hand, overwatering can cause root rot so always check soil moisture before watering.
Checklist:
✔ Water deeply 2-3 times a week instead of shallow daily watering.
✔ Avoid watering in the evening to prevent fungal issues.
✔ Use drip irrigation or soaker hoses for efficient watering.
A soil moisture meter is a helpful tool for determining when to water. Always adjust based on weather conditions and soil type.
Stay on Top of Your May Garden Tasks
A thriving May garden doesn’t happen by accident but requires consistent care. Planting summer crops, feeding perennials, controlling weeds, watching for pests, and adjusting your watering schedule sets up your plants for a strong growing season ahead.
