August Garden To-Do List for Exeter
August Garden To-Do List for Exeter
August in Exeter is a season of abundance and transition all at once. The tomatoes are heavy on the vine, the perennial beds are at their fullest, and yet there's a subtle shift in the air as the first cool nights hint at what's coming. Here on the Seacoast, this month is a pivot point, a chance to enjoy summer's rewards while quietly preparing for the fall ahead.
If you've felt your garden getting away from you these past few weeks, you're in good company. August is the perfect time to regroup, tidy up, and set your landscape up for a graceful finish to the season.
Keep Up with Watering as the Heat Lingers
Even as evenings cool, August days can stay stubbornly hot and dry. Exeter's inland position, a little further from the ocean's moderating breeze than towns right on the coast, means gardens here can bake under late-summer sun. Consistent watering remains essential.
Water deeply and less often rather than lightly every day. This encourages roots to grow downward, building resilience against drought. Early morning is the ideal time, giving foliage a chance to dry and reducing the risk of disease.
Pay special attention to anything planted this year. Young shrubs, trees, and perennials haven't yet developed the deep root systems that carry established plants through dry spells.
Refresh Your Mulch
By August, the mulch you laid down in spring has often thinned, broken down, or drifted away. Refreshing it now pays real dividends. A renewed layer conserves moisture, moderates soil temperature, and keeps late-season weeds from taking hold.
In Exeter's variable soils, from sandy patches to heavier loams near the river, mulch also protects the delicate feeder roots near the surface. Keep it a few inches away from trunks and stems to prevent rot. Two to three inches is the sweet spot.
Stay Ahead of Weeds
Weeds don't slow down in late summer, and many are racing to set seed before fall. Every weed you pull now is dozens you won't fight next year. A steady habit of weeding, even ten minutes at a time, keeps the problem manageable.
Focus on removing weeds before they flower and go to seed. Pull them after a rain or a deep watering, when the soil is soft and roots release cleanly. This is one of the most valuable things you can do for next season's garden.
Deadhead and Tidy Perennials
Many perennials get a second wind if you keep them deadheaded. Removing spent blooms redirects the plant's energy and often coaxes out fresh flowers. Coneflowers, black-eyed Susans, and daylilies all respond well to this attention.
Cut back any foliage that's gone tired, yellowed, or mildewed. Improving airflow around your plants reduces disease pressure as humidity lingers. A little grooming now keeps beds looking intentional rather than overgrown.
Begin Selective Pruning
August is a thoughtful time for light, corrective pruning. Remove dead, damaged, or crossing branches on shrubs and ornamental trees to improve structure and airflow. Avoid heavy pruning of spring-blooming shrubs now, though, as you'd be cutting off next year's flower buds.
This is delicate, judgment-based work. Knowing which branches to take and which to leave is the difference between shaping a plant and stressing it. When in doubt, a lighter hand is always safer, or call in an experienced eye.
Plan for Fall Planting
Here's the exciting part: some of the best planting of the year is just ahead. The warm soil and cooling air of early fall create ideal conditions for establishing new trees, shrubs, and perennials. August is the time to plan those additions and prepare their beds.
Take stock of the gaps in your landscape now, while the garden is full and you can see clearly what's thriving and what's missing. Sketch out your ideas, amend your soil, and you'll be ready to plant when the moment arrives. Exeter's long, mild autumns give fall plantings plenty of time to settle in before winter.
Start a Fall Vegetable Garden
Don't let your vegetable beds go quiet. Early August is your last good window to sow quick-maturing crops like bush beans and summer squash, while cool-season greens, spinach, lettuce, and kale can go in throughout the month. Root crops like carrots, beets, and radishes sown now will sweeten with the first light frosts.
Our Seacoast growing season stretches later than many expect, and a fall garden rewards the effort generously. Fresh greens on your table in October are well worth a bit of August planning.
