Keep Your Garden Thriving Through Cold Snaps
When fall temperatures dip in Newtown, PA (Zone 7a), frost can arrive earlier than expected—sometimes overnight. Even a light frost can damage tender annuals, vegetables, and young perennials. The good news? With a few smart steps, you can protect your garden and keep plants healthy until the season’s end.
At Marrazzo’s Garden Center, we’ve been helping local gardeners protect their plants since 1947. Here’s how to guard against frost and give your garden a head start next spring.
Use Frost Covers for Protection
Frost covers, row covers, and old bedsheets can create a barrier that traps heat radiating from the ground.
-
Timing is everything: Cover plants in the late afternoon before temperatures drop.
-
Support the fabric: Use stakes or hoops to prevent the cover from touching the foliage.
-
Remove in the morning: Allow sunlight and air circulation once the frost has melted.
💡 Pro tip: Pick up frost blankets and plant protection fabric at Marrazzo’s Garden Center before the first cold front hits.
Mulch to Insulate Roots
Mulch acts as nature’s blanket, keeping soil temperatures stable.
-
Apply 2–3 inches of mulch around perennials, shrubs, and young trees.
-
Use organic options like bark mulch, shredded leaves, or straw.
-
Keep mulch a few inches from stems to prevent rot.
Mulching in fall not only protects roots from frost but also helps retain moisture and suppress winter weeds.
Watch the Weather and Act Fast
In Bucks County, the first frost usually arrives in mid- to late October.
Stay alert to overnight lows below 35°F—especially on clear, calm nights when frost is most likely. Move potted plants indoors or into a sheltered area when frost warnings are issued.
Tip: If you’re unsure which plants are frost-sensitive, our experts at Marrazzo’s can help you identify what needs covering and what can safely stay outdoors.
FAQ: Protecting Plants from Frost
Q: What’s the difference between frost and a freeze?
A: Frost forms when moisture freezes on plant surfaces, typically at 32°F. A freeze is colder and longer-lasting, often damaging even hardy plants.
Q: Can I use plastic to cover plants?
A: Avoid direct contact—plastic can transfer cold to leaves. Instead, use a cloth layer underneath or invest in breathable frost covers.
Q: When should I remove mulch in spring?
A: As soon as daytime temperatures consistently stay above 50°F, pull mulch back slightly to allow new growth to emerge.
Quick Takeaway
Protecting your plants from frost doesn’t have to be complicated. With the right timing, materials, and guidance, you can keep your garden beautiful well into the season and ensure healthier growth next year.
