As we wrap up May and step into June, the garden feels like it’s in full swing—but also, like it’s entering a new chapter. The spring blooms and first harvests of lettuce and sugar snap peas are winding down, and the tomatoes, okra, and squash are ready to steal the show.
If you’ve been following the 15-Minutes-a-Day Gardening Calendar, you know this whole journey is about creating a garden that’s sustainable, joyful, and manageable—no matter how full your schedule is. We started with slow, intentional prep back in January. We built momentum through February and March, and we reveled in spring growth through April and May. Now? It’s time to shift gears for summer.
June is a turning point in the garden. The heat is no longer creeping in—it’s here. That means our gardening strategy needs to shift too. This month is about supporting what’s already growing, planting what thrives in the heat, and making small adjustments every day so we’re not caught off guard by rising temps, pests, or fading crops.
I know from experience: this is where that 15-minutes-a-day habit really becomes a lifesaver. You don’t need to overhaul your entire garden in a weekend. You just need to check in, water deeply, harvest what’s ready, and give a little TLC to your hardworking summer plants.
Let’s look at what to plant next—and how to keep your garden thriving through June and beyond.
