Winter Gardening MISTAKES: 15 Things NOT to Do!

Written by Emily Belkoff

Last winter, I learned some tough gardening lessons the hard way when I lost my beloved butterfly bush and several perennials to improper winter care. 

After that expensive mistake, I’ve made it my mission to protect my garden during the cold months. 

Here are the crucial mistakes you’ll want to avoid!

1. Late Season Planting

Risks for Perennials

I once tried squeezing in some last-minute perennials in November – big mistake! The freezing and thawing cycle pushed my plants right out of the ground, exposing their delicate crowns to harsh winter conditions.

Timing Guidelines for Plant Establishment

My garden rule now is to get everything in the ground at least six weeks before the first freeze. While trees and shrubs are a bit more forgiving, I’ve learned it’s better to wait until spring than plant too late in fall.

2. Improper Fall Pruning

Effects on New Growth

Last year, I made the rookie mistake of pruning my butterfly bush in October. The poor thing sprouted tender new growth that got zapped by the first frost.

Timing and Best Practices

Now I mark my calendar to finish all pruning by late August. For plants like butterfly bush and caryopteris, I’ve learned to resist the urge to prune until spring.

3. Slug Management

Fall Prevention

Those slimy garden menaces fooled me for years until I discovered their sneaky fall egg-laying habits. Now I know autumn is actually prime time for catching them before they multiply.

Control Methods

My trusty flashlight and I have become quite the night patrol team! I keep a special “slug bucket” of soapy water ready, and my kids actually enjoy helping me spot these garden pests during our evening rounds.

4. Protecting Non-Hardy Plants

Taking Cuttings

After losing my entire collection of Mexican Bush Sage one winter, I’ve become a propagation pro. Now I take cuttings of my favorite tender plants before the first freeze hits.

Plant Varieties to Save

My sunroom has become a winter sanctuary for cuttings from my pineapple sage, colorful coleus, and fragrant mints. Most root easily in water – it’s like having a mini greenhouse!

5. Tree Care in Winter

Watering Requirements

The $200 maple tree I lost taught me an expensive lesson about winter watering. Young trees need consistent moisture, even in winter months.

Protection Methods

I’ve found that water bags are worth their weight in gold for newly planted trees. They’re like a slow-release water bottle for your tree’s roots.

6. Self-Seeding Plant Control

Problem Plants

My Joe Pye Weed nearly took over half the garden last year! While these volunteers can be charming, they can quickly turn from friend to foe.

Prevention Techniques

I now spend cool autumn evenings with my pruners, catching those seed heads before they spread. It’s actually become one of my favorite fall gardening tasks.

7. Indoor Plant Transition

Temperature Guidelines

After losing my favorite potted ferns to an unexpected frost, I’ve become almost obsessive about checking nighttime temperatures. When the forecast shows nights dipping below 55°F, it’s moving day in my garden.

Timing Considerations

That one surprise September snow taught me to be proactive. Now my plants get their indoor winter vacation well before any weather surprises.

8. Winter Mulching

Importance and Benefits

I used to think mulch was just for looks until I saw the difference in my perennial beds. The mulched plants emerged strong and healthy in spring, while the bare spots suffered significant losses.

Application Methods

My go-to winter protection now is a cozy 2-inch blanket of mulch around all my precious plants. Think of it as tucking your garden in for a long winter’s nap.

9. Pre-Snow Garden Cleanup

Pest Prevention

Nothing’s worse than spotting plant debris emerging from melting snow in spring. I learned this lesson after dealing with a massive pest problem that could have been prevented.

Timing and Tasks

One crisp autumn afternoon of cleanup saves me countless headaches in spring. Plus, it’s much more pleasant than working with frozen fingers!

10. Winter Weed Control

Temperature Requirements

I wasted so much weed killer one cold October day before understanding that timing is everything. Those stubborn weeds need warmth to actually absorb the treatment.

Effective Timing

Now I tackle my weed problems in early fall when temperatures hover in the 60s. It’s more effective and uses less product – a win-win for my garden and wallet.

11. Vegetable Garden Cleanup

Pest Prevention

The year I left my bean plants standing over winter was a disaster. Those Mexican bean beetles had the coziest winter home ever, and boy, did they thank me by multiplying in spring!

Proper Disposal

I’ve learned to be ruthless with infected plants. Instead of adding them to my compost pile, they go straight into yard waste bags. Better safe than sorry!

12. Winterizing Garden Equipment

Hose Management

After replacing three cracked hoses in one season, I finally got smart about winter prep. Now I have a whole hose disconnection ritual every fall.

Water Line Protection

That one frozen pipe taught me an expensive lesson. These days, I’m religious about shutting off those interior valves before the first freeze hits.

13. Leaf Management

Lawn Protection

My first winter as a homeowner, I thought leaving leaves was “natural.” Come spring, I had patches of dead grass where thick leaf mats had smothered it.

Leaf Utilization

Now I turn those fallen leaves into garden gold! My leaf vacuum is one of my favorite garden investments – it transforms autumn cleanup into free mulch and compost.

14. Winter Shrub Pruning

Snow-Area Considerations

Living in snow country means my tall shrubs need special attention. I learned this after watching my beautiful hydrangeas split under heavy snow.

Specific Plant Guidelines

My knockout roses and hydrangeas get their annual “haircut” right after the hard freeze. It’s like giving them a winter-ready makeover.

15. Frost Protection

Tools and Equipment

Those $25 frost blankets have saved hundreds of dollars worth of plants. They’re like cozy sleeping bags for my garden!

Cost and Coverage

I keep several 18-foot frost protection kits ready to go. They’ve saved my late-season vegetables more times than I can count, extending my harvest well into the cooler months.
