September Garden Survival Guide: What to Prune, Plant, and Prep Before First Frost

As summer fades and the crisp edge of fall creeps in, it’s time to shift gears in the garden. September is nature’s reminder that your growing season has an expiration date, and smart gardeners know how to use these final warm weeks to their advantage.

From strategic pruning and transplanting to fall veggie planting and perennial prep, here’s your September game plan. We’ve included the right tools for every job and links to expert tips from past Woodland Tools blogs.

1. Prune with Purpose: Out with the Dead, In with the Prep

While spring gets all the pruning hype, September is your last, best chance to clean up summer’s mess before cold weather sets in. Focus on:

Removing dead or diseased growth
Clearing away crossing or rubbing branches
Shaping up hedges, vines, and overgrown perennials

Tool of the Month: Our Heavy Duty Bypass Pruner is perfect for clean cuts on green stems up to 5/8". For thicker or tougher cuts, the Super Duty Bypass Pruner handles up to 3/4" with gear-assisted cutting power.

Pro Tip: Avoid pruning spring bloomers like lilacs or forsythia now. They’ve already set buds for next year. Instead, focus on cleaning up spent flowers.

2. Time to Tackle the Thick Stuff

Woody shrubs, invasive brambles, and wayward tree limbs need attention now before the foliage drop hides them from view.

The Duralight Compact Anvil Lopper is ideal for dry, dead growth up to 1.25" thick.
Use the Super Duty MaxForce Lopper when you're dealing with dense branches or stubborn vines.
Reach high limbs safely with the Heavy Duty 14' Tree Pruner, perfect for fall fruit tree cleanup or trail clearing.

September is also a good time to remove suckers and water sprouts. Doing it now means fewer unwanted shoots next spring.

3. Still Time to Plant? You Bet.

If your garden feels like it's winding down, don’t pack it in just yet. Cool-season crops thrive in September.

Plant quick-maturing fall favorites like:

Spinach, kale, arugula, and lettuce
Radishes, carrots, and beets
Cilantro, dill, and parsley

Use the Heavy Duty Transplanter for deep, stable planting and the Heavy Duty Cultivator to refresh soil with compost or amendments.

4. Divide and Conquer Perennials

Now is the perfect time to divide spring and summer perennials that are overcrowded or declining in bloom.

Target plants like:

Hostas
Daylilies
Black-eyed Susans
Irises

Our Heavy Duty Weeder helps lift and separate roots with minimal damage. Once replanted, add mulch and water well to support healthy regrowth.

5. Get Your Beds Winter-Ready

Prepping your beds now means fewer chores next spring and healthier soil over winter.

To-do list:

Pull out dying annuals
Add a layer of organic mulch to protect soil
Remove weeds before they go to seed
Cover any bare soil with compost or leaf mulch

Don’t forget about your lawn. September is the final call for aerating, seeding, and fertilizing cool-season grasses in many regions.

6. Tool Care Before the Cold

Your tools deserve a little love after a long season. Caring for them now keeps them in top shape and ready to go next year.

Steps to follow:

Clean dirt and sap off blades
Sharpen pruners, loppers, and shears
Lightly oil pivot points and blades
Store indoors to prevent rust
