Snow Garden: 5 Ways to Winterize & Boost Spring Growth

For most of the country, winter brings snow, but that snow doesn’t have to be wasted. It can actually benefit gardens, helping to protect plants and provide essential nutrients when spring arrives.

Use Snow to Insulate Plants

Frigid winter weather can be damaging to delicate plants. Fortunately, fallen snow can act as natural insulation, sheltering plants from freezing temperatures.

“A layer of snow that’s anywhere from at least 2 inches deep can be great for insulating the soil and protecting any overwintering plants you have from the cold and harsh winds,” says Angelika Zaber, lawn care specialist and garden expert for Online Turf. “Simply leave it alone and over time, it will melt by itself.”

Heavy snow can break branches or flatten delicate stems, so it’s best to gently brush it off shrubs and young trees after a storm, according to Tammy Sons, founder and CEO of TN Nursery.

Protect Buried Bulbs

Similar to insulating perennials, a layer of snow can also protect the bulbs in your garden, leading to beautiful blooms in spring. “Fallen snow can also be a gardener’s friend in winter,” Sons says. “When it has blanketed my beds, I use it as an insulator protecting perennials and bulbs from rapid temperature fluctuations that can heave roots or crack pots.”

While cold can damage plants, warmer weather too soon can also be detrimental to bulbs by causing them to sprout early. Snow insulation can help prevent this.

For bulbs planted in containers, a layer of snow might not be enough protection. “For bulbs planted in pots, I bring them near the house or into an unheated shed or garage where they will still be cold but won’t be subjected to repeated freeze-thaw cycles,” Sons says.

Track Wildlife

A layer of snow can help with winter wildlife watching. Observing animal footprints can help track which animals visit your garden, and potentially make birdwatching easier.

“Regularly inspecting a fresh layer of snow is a great way to track any wildlife activity in your garden,” Zaber says. “After just a few days, not only will you be able to discover which animals frequently visit your space but also be able to see the trails that they have established.”

Add Moisture to Soil

As snow melts, it provides your garden with an early watering. “If it melts slowly, snow can offer deep, sustained moisture that soaks into the soil,” Sons says. Slow melting allows more water to soak in, replenishing groundwater and reaching root systems that are buried deep underground.

Snow can also be collected for later use. “You can collect water using rainwater barrels and fill them with snow,” Zaber says. “Over time, the snow will melt and you’ll have lots of water that you can use for your garden for free.”

Fertilize Your Soil

Snow contains nitrogen from the atmosphere, which can enrich your garden’s soil as it melts. Nitrogen is a key nutrient for healthy plant growth. While the amount of nitrogen in snow is small, it provides an extra boost when combined with compost or organic fertilizer.
