Garden Survival Guide: What to Do Before the First Frost

Here at Savings.com, we don’t just save you green; we save your greens.

When the first chilly nights show up in the forecast, your garden starts winding down. A little smart prep now helps everything bounce back faster in spring. Below is a simple, step‑by‑step way to tidy what’s tired, insulate what’s staying, feed what’s hungry, and protect it all from surprise cold snaps.

Set your frost clock

Look up your average first frost date and watch the 10‑day forecast. Those two numbers shape your plan: a light freeze around 29–32°F nips tender annuals, a moderate 25–28°F damages most plants, and a hard freeze at 24°F or below ends the season. Aim to finish heavy bed prep and moving plants indoors 3–6 weeks before your expected frost, then shift to quick‑deploy protection as the date approaches.

Give your soil a fall reset

Healthy beds carry you through winter and reward you in spring. Start by clearing out spent plants. Anything healthy and pest‑free can be chopped and composted (shredded dry leaves speed things up).

Once tidy, spread 1–2 inches of finished compost across vegetable and perennial beds and work it into the top couple of inches. This quiet “top‑dress" feeds soil life all winter.

If a bed will rest, sow a cover crop. Crimson clover is a solid, home‑garden pick. Aim to sow 4–6 weeks before hard freeze so roots establish. In spring, mow before it flowers, let it wilt, and work it in as a green mulch.

Perennials and shrubs: what to cut, what to keep

Not everything needs a haircut. Many plants—coneflower, black‑eyed Susan, sedum, switchgrass, little bluestem—look great in winter and feed birds. Others are better cut back once foliage collapses or after the first light frost. With sharp, sanitized shears, trim spent herbaceous perennials like hosta, daylily, peony, bee balm to 1–2 inches above soil, cutting at a slight angle to shed water. Trash diseased stems; don’t compost them.

Finish by insulating roots. Pull mulch back from crowns, then re‑apply 2–4 inches around perennials, shrubs, and young trees. Keep a clear space—about a palm’s width—around stems and trunks to prevent rot. Young or thin‑barked trees appreciate a trunk wrap, and hardware‑cloth guards deter rabbits and voles.

Veggie beds: harvests, holdovers, and what to plant now

As frost nears, harvest tender crops—tomatoes, peppers, cucumbers, basil, summer squash. Cold‑tough types can stay with help. Kale, collards, chard, leeks, carrots, beets ride out cold if you protect soil: tuck 4–6 inches of clean straw or dry leaves around roots and cover leafy beds with frost cloth on freezing nights. Vent covers in the morning so sun doesn’t overheat plants.

Fall is prime time for garlic and spring‑blooming bulbs. Plant garlic cloves 2–3 inches deep and 6 inches apart, points up; mulch 2–4 inches (use 4–6 inches in colder zones). For bulbs like daffodils and tulips, plant at a depth 2–3× the bulb’s height and water once to settle.

Want extra winter harvests? Build a quick low tunnel: bend wire or ½‑inch PVC into hoops every 3–4 ft, drape frost cloth, clip the ridge, and weigh down edges—especially on the windward side. Vent after freezing nights when the sun returns.

Containers and tropicals: moving day, done safely

Containers are easiest to protect—many can simply come inside. Move before nights regularly dip below 50°F for tropicals (citrus, hibiscus, basil) and 40°F for subtropicals (rosemary, olive). Check for pests, rinse foliage, and quarantine new arrivals indoors for a week before placing them in bright light. A sturdy, multi‑tier stand keeps plants organized with good airflow; add grow lights if windows are limited.

Frost protection you can set in seconds

Keep frost cloths or zippered plant covers within reach. On freezing nights, drape fabric so it reaches the ground and anchor the edges—that trapped air is your insulation. Use hoops to keep fabric off leaves (contact can transmit cold). Skip unlined plastic directly on foliage, and always vent in the morning once temperatures rise.

Lawn care that pays you back in spring

Cool‑season lawns (fescue, bluegrass, rye): aerate compacted areas, overseed thin spots, feed with a fall fertilizer, then apply a late‑fall winterizer and water in lightly. Make your final cuts around 2.5–3 inches.

Warm‑season lawns (Bermuda, zoysia, St. Augustine, bahiagrass): ease off high‑nitrogen feeding in late fall; a potassium‑forward winterizer may be appropriate—follow the label.
