May Garden Care Tips

✅ Mulch Everything
A layer of mulch around your plants helps retain moisture, suppress weeds, and regulate soil temperature.

✅ Water Wisely
Water deeply and early in the day to avoid evaporation. As temps climb, your plants will need more frequent but deep watering.

✅ Watch for Pests
With warmer weather, pests like aphids and whiteflies become more active. Inspect plants regularly and treat organically when possible.

✅ Deadhead Flowers
Remove spent blooms to encourage new growth and extend your flowers’ lifespan.

Keep Your Garden Happy and Healthy

With a little smart planting and regular care, your garden will thrive through the hot months ahead. May is all about creating strong, resilient plants and landscapes that will carry you through summer beautifully.
