July is peak summer living in Minnesota. We’re soaking up sun at the beach, snuggling up with a good book on the patio, and lighting up the grill to gather with loved ones. The hurdle of starting the garden is behind us — the heavy lifting of spring planting and maintenance of getting going.

But there’s one non-negotiable thing that will keep your plants (and you) thriving this month: water. That’s the bare minimum. Beyond that, there’s a handful of strategic moves that transform a surviving landscape into a thriving one.

Here’s everything you need to know for July gardening.

GARDEN: Water Like Your Plants’ Lives Depend on It

They do, actually.

July is when heat spikes, when containers dry out in hours, when even established perennials start to stress. Water is the difference between thriving plants and struggling ones.

Water Deeply, Early, and at the Base

Water deeply at the soil level, before 10 AM when possible. This is crucial. Morning watering gives plants time to absorb moisture before the day’s heat peaks, and it allows foliage to dry quickly, preventing fungal disease.

More importantly, water deeply. Shallow watering encourages shallow roots. Deep watering forces roots down into cooler soil where they access moisture even during heat waves. This is especially important for perennials — remember, natives, shrubs, and trees have deep root systems that can reach 6–15 feet down. You’re not just wetting the surface. You’re filling the entire root zone. 

How to tell if you’re watering deeply enough:

• Take a trowel and dig 2–3 inches into the soil after watering. Does the soil feel moist down there? That’s deep watering. Is it dry? Water more.

Account for Rainfall

• Nature provides water, too. One inch of rain per week is the target for new plantings and non-native perennials and shrubs to thrive. If you get a good rain week, you might not need to water at all.

But here’s a key difference: native plants, once established, need no supplemental water. Their deep roots find moisture deep in the soil. If you’ve planted natives and they’re established (past their first full growing season), step back. Let them thrive on natural rainfall alone.

Plant Late-Season Bloomers for Continued Pollinator Support

July is the perfect time to plant perennials that bloom late summer through fall — when pollinators are preparing for migration and need maximum nectar sources.

Late bloomers to plant now:

• Sedum: blooms late summer, incredibly low-maintenance and drought-tolerant
• Black-eyed Susan: native and ornamental varieties, reliable favorite, blooms mid to late summer
• Turtlehead: native and ornamental varieties, shade, blooms late summer, loves moisture
• Joe Pye weed: native, tall, dramatic, late blooms
• Asters: native and ornamental varieties, fall bloomers, pollinator magnets

These fill the gap when spring and summer bloomers have faded. Pollinators depend on them!

Refresh Tired Annuals

Spring annuals loved cooler temps. Now, in July heat, many are struggling, fading, or done blooming. This is the time to refresh.

What to do:

• Take a walk through your beds and containers
• Identify annuals that are struggling (leggy, brown, done blooming)
• Replace them with heat-lovers: zinnias, lantana, vinca, portulaca
• Keep what’s thriving (your tried-and-true performers)

You’re not replacing everything — just the ones that aren’t earning their spot. This gives you a second wave of joy and color through August and September.

Trim Back Growers

Salvia, nepeta, petunias, and other bloomers get leggy in mid-summer. Pinch back the top 2–4 inches to encourage bushier growth and more blooms.

This is maintenance pruning — not heavy cutting. You’re just tidying up and encouraging fullness. Do it now, and you’ll have fuller, more floriferous plants through fall.

Harvest Herbs and Vegetables at Peak

Basil is at its absolute best in July. Tomatoes are sizing up. Peppers are putting on growth. Herbs are fragrant and flavorful.

Harvest regularly — this encourages more growth and prevents plants from flowering. For herbs specifically, remember to pinch stems, not just leaves. Pinching at a leaf node (where leaves branch) causes the plant to split into two stems at that point, creating exponential bushiness. Just pulling leaves keeps the plant leggy and sparse.

Don’t Forget About Fertilizer

Fertilizer timing matters — especially in July heat.

• For perennials, shrubs: Apply one slow-release fertilizer ASAP (ideally before July hit). Or apply once monthly for rehab feeding. Stop fertilizing before September so plants can harden off for winter.
• For annuals: Feed every 1–2 weeks with liquid fertilizer. They’re blooming nonstop and need consistent nutrient replenishment.
• For tropicals: Feed every 2–3 weeks through the entire season for continuous blooms.

Important: Don’t fertilize on days when temperatures are 85°F or higher. Heat + fresh nitrogen = plant stress. Wait for cooler days.

HOME: Care for Yourself, Too

While your plants need water, so do you. Seriously.

Stay Hydrated During Garden Work

Tending a garden in July is hard work. Take breaks, drink water, and wear sunscreen. Your body needs the same deep hydration and care you’re giving your plants!

Treat Your Hands

Working hands deserve TLC. If you’re gardening, weeding, digging, and planting, your hands are taking a beating. Our new Mackenzie’s Fisherman line at Trill Boutique has a scrub and salve formulated specifically for working hands — softening rough skin while keeping that earned, gardener callousness.

Treat yourself. Or gift it to a gardener on your list who’s earned some hand care.

Dial In Summer Entertaining

July is peak summer living. You’ve worked hard on your landscape all season. Show it off!

Gather with loved ones at home for intimate gatherings – a backyard dinner, an evening gathering around the fire pit, a casual coffee date on the patio.

The easier entertaining is, the more often you’ll do it. A staple serving set designed for outdoor use makes a difference — beautiful enough to show off, durable enough to actually use, easy enough to reach for again and again.

Shop Trill Boutique for serving sets, tableware, and hosting essentials made from thoughtful materials in timeless designs. Invest in pieces that make entertaining effortless for years to come.

LANDSCAPE: Maintenance That Matters in Peak Heat

Water Deeply — Irrigation Alone Isn’t Enough

Irrigation systems are great for lawns with shallow roots. But garden beds, shrubs, and trees need deep watering that hand-watering provides. Irrigation sprays the surface. You need to water deeply.

Make hand-watering a priority for non-lawn areas. This is when it really counts.

Mulch If You Haven’t Yet

If you skipped mulching in spring, do it now. A 2–3 inch layer of mulch around trees, shrubs, and perennial beds dramatically reduces water loss during peak heat. Mulch keeps soil cool, retains moisture, and suppresses weeds.

Mulch is one of the easiest, most impactful landscape maintenance tasks. Do it now!

Avoid Heavy Pruning in July

Pruning during peak heat is stressful for plants. They’re already stressed by temperature and water demands. Heavy pruning adds injury to that stress.

Only prune for disease. If you see dead branches, diseased growth, or hazardous limbs, remove them. Otherwise, wait until fall or next spring.

Exception: Some plants can handle pruning in July without stress:

• Boxwood: can take hard pruning
• Yews: reliable pruners
• Hedges: if you’re maintaining them
• Peonies: remove spent blooms
• Iris: deadhead spent flowers

When in doubt, leave it alone until cooler weather.

Watch for Powdery Mildew and Fungal Issues

July’s combination of heat, humidity, and rain creates perfect conditions for fungal disease. Powdery mildew especially loves this weather.

Take time to observe your plants. Look for white powdery coating on leaves, yellow spots, unusual wilting. Catch fungal issues early before they spread.

Prevention is easier than treatment:

• Ensure good air circulation (prune for airflow)
• Water at the base, not on foliage
• Water early so leaves dry quickly
• Remove heavily infected leaves

If you spot issues, we have products and expertise in-store. Catch it now before it takes hold.

Apply Repellents for Continued Protection

Especially if you’re traveling or taking weekend trips to the cabin, apply repellents like Repel-X Perimeter for continued protection against deer and rabbits. This keeps your landscape thriving while you’re away.

Continue Weeding Before They Spread

Weeds love July heat as much as you love your patio! Stay on top of weeding before they flower and spread seed. A few minutes of weeding now saves hours of work in August.

The July Mindset

July is about maintenance, not transformation. The heavy lifting is done. Now you’re maintaining, observing, and enjoying. Water deeply. Watch for stress. Refresh what’s struggling. And most importantly, spend time in the space you’ve built!

You earned this. A thriving landscape in peak summer is something to celebrate.
