Keep Your Garden Thriving Through Chilly Nights

When fall temperatures dip, a sudden frost can take even experienced gardeners by surprise. Knowing how to protect your plants from frost is key to keeping your garden beautiful and productive well into the season. With a little preparation—and the right tools from Bru-Mar Gardens in Annapolis, MD—you can shield your plants from damage and enjoy your garden longer.

Understand When Frost Happens

Frost typically occurs on clear, calm nights when temperatures fall below 32°F. In USDA Zone 7b, light frosts can happen as early as late October, so it’s smart to plan ahead. Keep an eye on local forecasts, especially after warm days followed by still, cool evenings.

Cover Up for Protection

Frost cloths, garden blankets, and even old sheets can create a barrier that traps heat and shields tender plants from frost.

  • Use breathable fabric—plastic can trap moisture and cause damage.

  • Drape covers loosely, anchoring them to the ground to trap warmth.

  • Remove covers in the morning once temperatures rise to prevent overheating.

At Bru-Mar Gardens, you’ll find frost blankets, burlap, and plant covers that are easy to reuse all season long.

Mulch to Insulate Roots

Mulch acts as a natural insulator, protecting plant roots from temperature swings.

  • Apply 2–3 inches of mulch around the base of plants, keeping it an inch away from stems.

  • Use organic options like shredded leaves, straw, or bark mulch.

  • For container plants, move pots close to your house or cluster them together for extra warmth.

Timing Is Everything

Water your plants a day before frost—moist soil holds more heat than dry soil. Avoid fertilizing late in the season, which can encourage new growth that’s easily damaged. Instead, focus on protection and maintenance.

Quick Tips for Frost Protection

  • Bring tender annuals indoors overnight.

  • Protect newly planted perennials or shrubs with mulch mounds.

  • Harvest remaining herbs or veggies before a hard freeze.

Quick Takeaway

A little preparation goes a long way in extending your gardening season. Use covers, mulch, and timing to protect your plants from frost and enjoy a healthy, vibrant landscape even as temperatures fall.
