First Frost


Frost Changes the Season

It doesn't end it. A calm plan from fall into winter.


The first frost is a natural turning point. The mums fade, the annuals soften and the porch starts to look a little tired.

It's tempting to empty everything and stack the planters away until spring. There is a better way: keep the structure, edit the plants and let your planters carry the season.

01

When to make the switch: reading the first frost

A light frost, around 0°C, touches tender annuals and leaves most hardy plants untouched. A hard freeze, −2°C or colder for several hours, ends most summer and early-fall plantings. Watch the overnight forecast: the week of your first light frost is the right time to start editing, and you want your winter arrangement in place before the soil freezes solid.

Not sure what will survive where you live? Check your Canadian plant hardiness zone and choose plants rated at least one zone colder, since roots in containers are more exposed than roots in the ground.

02

What to pull, what to keep

Edit rather than empty. Most fall planters have a few pieces worth keeping.

Pull

Spent mums, coleus, sweet potato vine, begonias and anything dark or limp after the first cold night.

Keep

Ornamental kale and cabbage (their colour often deepens in the cold), heuchera, sedum, grasses, pansies and violas.

Bring in

Tropicals and tender perennials such as mandevilla, hibiscus or rosemary, before nights fall below freezing.

Ornamental kale holds its shape, and its colour, well past the first frost.

03

Building a winter arrangement

Winter planters rely on form rather than flowers. Think in three layers:

  • Height  Birch poles, red or yellow dogwood stems, or curly willow. Set them in the centre first.
  • Fullness  Cut evergreen boughs (cedar, white pine, fir or boxwood) tucked in around the edges, angled outward.
  • Accent  Winterberry, pinecones or magnolia leaves for texture and warmth against the green.

Leave the existing soil in place: it anchors stems and boughs all winter. Water the arrangement in before the soil freezes so everything sets firmly.

A note on self-watering planters

If you use a self-watering Fairfield or Augusta planter, empty the reservoir before a hard freeze. Winter arrangements of cut greens need very little water, and an empty reservoir keeps things simple until spring.

04

Moving plants indoors

Tender plants that summered on the porch can winter in a bright room. Choose a spot with good light, away from heat vents, and check for pests before bringing anything inside. Planters designed for indoor and outdoor use make the move easier: Serene brings clean, ribbed lines to smaller plants, and the Evolve Tall Planter comes with a removable insert and drip tray. Evolve is made in Canada from 100% post-consumer polypropylene.

Why the planter matters

A winter planter does its most visible work when everything else in the garden is resting. Weight, drainage and material all matter. That's what lets the planter stay put while the plants inside change with the seasons.

A simple winter porch recipe

For a front entrance that holds from the first frost until spring, start with a pair of tall planters on either side of the door.

 
Planters A pair of Augusta 26" Tall or Fairfield 34" Tall planters in black
Height 3 birch poles or 5–7 red dogwood stems per planter
Fullness A mix of cedar and white pine boughs, angled outward
Accent Winterberry stems and a few pinecones
Finish Warm white lights wound through the boughs for the shortest days
