🌸 How to Keep Your Garden Thriving Through Late Spring Heat

As May rolls into its later days, gardens are waking up fast—and sometimes, a little too fast. Sudden heat waves and shifting weather patterns can push young seedlings to bolt or wilt before they have a chance to mature. But don’t worry—Love & Vegetables has your back.

Let’s talk about how to keep your garden thriving in late spring, especially if you're in Zone 6 or similar climates.

☀️ Late Spring Challenges

By late May, you might face:

  • Surprise hot days (over 80°F)

  • Heavy rainfall followed by dry spells

  • Pests like flea beetles, aphids, and cabbage moths

  • Bolting in cool-weather crops like lettuce and spinach

🌿 7 Pro Tips to Keep Things Thriving

  1. Mulch Everything

    • Suppresses weeds

    • Retains soil moisture

    • Protects roots from sudden temperature swings

  2. Harvest Early and Often

    • Harvest lettuces, radishes, and herbs regularly to prevent bolting.

    • “Cut and come again” methods work well this time of year.

  3. Install Shade Cloth or Row Covers

    • Great for leafy greens and young transplants.

    • Protects from both sun scorch and insect pressure.

  4. Water Deeply, Not Frequently

    • Encourage deep roots to withstand heat.

    • Early morning watering is best.

  5. Keep Sowing Fast-Growers

    • Radishes, arugula, bush beans, and basil are all perfect for mid-late May sowing.

  6. Plant Summer Crops if You Haven’t Yet

    • Tomatoes, peppers, squash, and cucumbers should be in the ground now.

    • Harden off seedlings before transplanting.

  7. Watch for Pests Daily

    • Check the undersides of leaves.

    • Use insecticidal soap or neem oil if needed (but never spray in full sun!).

🧑‍🌾 What You Can Still Plant in Late May (Zone 6)

  • Beans (bush and pole)

  • Corn

  • Cucumbers

  • Summer Squash

  • Basil, Dill, Cilantro

  • Watermelon, Cantaloupe

  • Zinnias, Cosmos, and Marigolds for pollinators

🧰 Quick Tasks for This Week

  • Trellis your peas or tomatoes

  • Fertilize with compost tea or diluted fish emulsion

  • Start a pest log or garden journal

  • Add mulch to any bare spots

  • Thin crowded seedlings to improve air flow

🌼 Celebrate May's Momentum

It’s not just about keeping up—it’s about flowing with the season. Every seedling that makes it through May strong and steady sets the tone for a beautiful summer harvest. Keep learning, keep planting, and keep loving your garden.
