Step 1: After amending your soil, sit your plant – still in its container – next to the hole you’re digging to help you gauge how big it should be.

Yes, it’s true. Fall is a great time for planting perennials, trees and shrubs. After all, when they’re in the ground early, they’ve got a little extra time to get themselves established before the next growing season. But if you don’t take the time to plant right, the outcome can be disastrous!

Here’s the key when it comes to successful fall planting: Don’t take any shortcuts. That means proper bed preparation and digging the correct planting hole sizes. The best way to install any plant for faster root development – any time of the year – is by providing an ample area of loose soil around and under the containerized root ball. Many people don’t grasp the importance of proper planting prep. But truly, the easier you make it for the roots to grow, the faster your plants will become established.

Using a bare-minimum approach to planting in late fall is a recipe for disaster. All it takes is a few freeze-thaw cycles to heave up improperly planted material. Combine that with a winter that offers little to no snow cover (which won’t help insulate roots), and you’re guaranteed to lose a lot of plants.

When I was a landscape contractor in Michigan, I did a lot of fall plantings – and I didn’t plant any differently on Oct. 25 than I did in late May. And despite the fact I planted late into the fall season (even with light frost on the ground), I suffered few losses. This was 100 percent true until I was hired to create “Helen’s” fabulous perennial garden.

Step 2: Put the container in the hole to ensure you’ve got the proper planting depth.

Helen hired me to design and install a huge planting in October. We arrived to plant and discovered that beneath the mulch were two layers of weed barrier over hard, compacted clay soil. I wanted to remove the fabric so I could till and amend the soil – to get the plants off to a good start. Unfortunately, I was emphatically told we weren’t allowed to disturb the weed-free space. We were only given permission to make the necessary plant-size slits in the landscape fabric and to plant from there.

Tips
  • Don’t forget to water your plants in thoroughly (deeply) after planting – and regularly until the ground freezes. If temperatures should rise above freezing in winter, give your trees and shrubs another dose of water – especially if you haven’t got much snow cover.
Facts
  • Anyone living in the Snowbelt knows that winter’s freezes and thaws shift the earth around. (Think of all those cracked sidewalks and holes in the road.) This same soil upheaval can spell death for perennials, shrubs and trees that are not planted properly late in the season.
  • The only plants that don’t suffer injury or death from freezes and thaws are the large balled-and-burlapped woody plants. These root systems usually weigh enough to keep them from heaving out of the insulating soil around them.
Faqs
  • Q: Can I plant a shrub or tree that’s already lost its leaves and gone dormant?
    A: Yes! As long as you know the plant was healthy and alive before its leaves dropped for winter, the plant is better off in your planting bed than overwintered aboveground.
  • Q: Should I apply fertilizer to plants I install so late in the year?
    A: It’s a good idea to use a slow-release fertilizer. The plant’s roots will be awake before the weather (and soil) allow you to dig in the garden again. If the fertilizer is already there when the roots are ready for it, your plant should react to spring most heartily.
