How to Winterize a Fig Tree: Wrapping, Burying & Containers by Zone

Figs are subtropical at heart, and that is the whole challenge of growing them in a cold climate. The roots are reasonably hardy, but the wood that carries next year’s crop is not. Most common figs set their main “main crop” on new growth and an earlier “breba” crop on last year’s wood, so if winter kills the top growth back to the ground, the tree may regrow and survive but produce little or no fruit that season. Winterizing a fig tree is really about protecting that one-year-old wood through the cold so it lives to fruit. How far you need to go depends almost entirely on your USDA zone, your fig variety, and whether the tree is in the ground or a pot.

Know Your Zone and Variety First

Before you wrap anything, figure out whether you even need to. Cold tolerance varies enormously by variety. Hardy types such as ‘Chicago Hardy’, ‘Brown Turkey’, ‘Celeste’, and ‘Hardy Chicago’ can survive top growth down to roughly 10–15°F and recover from roots if killed lower. Tender varieties may suffer top-kill at 20°F or higher.

• Zones 8–10: Most figs need no winter protection at all. A heavy mulch over the root zone is plenty.
• Zone 7: Hardy varieties usually come through fine; in a cold snap they may lose some tip growth. A thick root mulch and, in exposed sites, a loose burlap wrap is good insurance.
• Zones 6: Expect top-kill on unprotected trees. Wrapping or burying is recommended to preserve fruiting wood and get a reliable crop.
• Zone 5 and colder: Outdoor in-ground figs will be killed back without serious protection. Burying, heavy wrapping, or growing in containers and moving them indoors is essentially required.

The single most important timing rule: do not wrap a fig that still has leaves or is actively growing. Wait until it is fully dormant and leafless, which usually means after the first hard frost. Wrapping too early traps moisture and warmth, inviting rot and tempting the tree to break dormancy during a warm spell.

Method 1: Wrapping the Standing Tree

This is the standard approach for in-ground figs in zones 6–7 and for smaller trees you cannot easily bend. The goal is a breathable but insulated cocoon that buffers the wood from extreme cold and drying wind.

1. After the tree is fully dormant, gather the branches gently inward and tie them together with twine into a compact column. Prune only lightly if needed to make the bundle manageable; save hard pruning for spring.
2. Wrap the bundled tree in several layers of burlap, or in old bedsheets, working from the bottom up and overlapping as you go.
3. For colder zones, surround the wrapped tree with a cylinder of chicken wire or hardware cloth and stuff the cavity with dry leaves, straw, or even crumpled newspaper for insulation.
4. Cap and cover the whole structure with a waterproof outer layer such as a tarp, heavy plastic, or a bucket inverted over the top, so the insulation stays dry. Leave a small gap at the very bottom for air to prevent rot.
5. Mound 6–12 inches of mulch or soil over the root zone for good measure.

The waterproof layer is critical, wet insulation is useless insulation, and a soaked, sealed wrap will rot the bark. The breathable burlap directly against the tree plus a shedding outer layer is the combination that works.

Method 2: The Buried-Trench Method

In zones 5 and colder, the most reliable way to keep a whole fig alive is to put it underground, an old technique brought to North America by immigrant gardeners. It works because soil is a far better insulator than air. This method suits young, flexible trees best; mature, rigid trees may snap.

1. In late fall, before the ground freezes, dig a trench in the soil on one side of the tree, slightly longer than the tree is tall and about a foot deep.
2. Use a spade to sever the roots on the opposite side of the trench, loosening the root ball so the tree can hinge over. This deliberate root-pruning is normal and the tree recovers in spring.
3. Tie the branches together, then slowly bend the entire tree down into the trench. Do this on a mild day when the wood is most pliable; bending in stages over a few days reduces breakage.
4. Pin the tree down, cover it with a layer of boards or carpet to keep soil off the bark, then backfill with soil and top with a thick mulch layer.
5. In spring, after hard frosts pass, uncover the tree, lift it upright, and stake or re-anchor it. The severed roots regrow.

Method 3: Overwintering Container Figs

By far the simplest strategy in any cold climate is to grow figs in pots and move them. Figs tolerate containers well and even fruit reliably in them. Because the tree is dormant and leafless over winter, it does not need light, just cool, stable temperatures and protection from a deep freeze.

1. Let the tree go fully dormant outdoors and drop its leaves after the first light frosts.
2. Move the pot into an unheated but protected space: an attached garage, a shed, a basement, or a cold cellar. The sweet spot is 30–45°F, cold enough to keep the tree dormant but above a hard, root-killing freeze.
3. Water sparingly, roughly once a month, just enough to keep the root ball from drying out completely. A dormant tree needs very little, and overwatering in storage causes rot.
4. In spring, after your last hard frost, bring the pot back outside gradually, hardening it off over a week so the new growth is not shocked by sun and cold.

If you have no suitable indoor space, you can cluster pots against a south-facing house wall, group them together, wrap the pots themselves in insulation (the roots are the vulnerable part in a container), and bury or heavily mulch the whole cluster. Pairing fig pots with other tender plants you bring under cover keeps your whole winter routine in one place; see our broader notes on protecting plantings in the outdoor living section and the companion guide on wrapping shrubs for winter.

Spring: Uncovering Without Setbacks

The mistake most growers make is uncovering too early. A warm week in late winter tempts you, but a hard frost afterward can kill tender new growth that was triggered to emerge. Wait until the danger of hard frost has reliably passed for your zone, generally March in zone 7, April in zones 5–6. Unwrap gradually rather than all at once, peeling back insulation over several days so the tree acclimates to light and temperature. Pull mulch back from the trunk to its normal level. Now is the time to prune: remove any wood that died back over winter, cutting to live, green tissue, and shape the tree. Feed lightly as growth resumes, and the protected fruiting wood will reward you with a far earlier and heavier crop than a tree that had to regrow from the ground.
