As we step into the warm embrace of July, many of us might think it’s too late to start planting. But let me tell you a little secret: July is actually a fantastic time to get your hands dirty and sow some seeds or transplant some seedlings.
Sure, the air is thick enough to cut with a knife, and most gardeners are retreating indoors with a tall glass of iced tea. But not us, right? We’re the diehards, the ones who see the scorching heat as a challenge, not a deterrent. Sure, our neighbors might think we’re a bit crazy for sweating it out in the garden, but they’ll be singing a different tune when we’re harvesting fresh veggies in the fall while they’re lamenting their long-gone summer crops!
While it’s true that some plants wilt faster than a chocolate bar in your back pocket on a July afternoon, there are still plenty of hardy souls in the plant world ready to take on the heat. With a little planning and some heat-beating tricks up our sleeves, we can keep the garden party going well into fall.
So, grab your widest-brimmed sun hat (you know, the one that makes you look like a walking umbrella), slather on that SPF 50, and let’s dive into 13 heat-tolerant plants that are tough enough to take on July in zones 4-6. Plus, I’ll throw in a to-do list of garden chores that’ll set you up for a bountiful late summer and fall harvest. Trust me, your future self will thank you when you’re enjoying fresh produce while everyone else is staring forlornly at their bare gardens!
Beets
Yes, you can plant beets in July! These root veggies are surprisingly heat-tolerant and can be sown directly in the garden for a fall harvest. Choose heat-resistant varieties like ‘Detroit Dark Red’ or ‘Chioggia’. Plant seeds 1/2 inch deep and 1 inch apart, thinning to 3-4 inches as they grow. Keep the soil consistently moist, and consider providing some afternoon shade to help them cope with the hottest days.

Broccoli
Broccoli in July? You bet! Start seeds indoors in early July for transplanting in August. Choose heat-tolerant varieties like ‘Belstar’ or ‘Green Magic’. These cool-season crops will appreciate the gradually cooling temperatures as they mature in fall. Provide plenty of water and consider using shade cloth to protect young plants from intense afternoon sun.
