How to Protect Fig Trees in Winter by Zone

Common figs (Ficus carica) are subtropical. UF/IFAS Extension reports that fully dormant trees take about 15 to 20F without severe damage. Penn State Extension puts the limit for most varieties near 20F, with real injury below 15F. Colder than that, the top of the tree dies back. Roots often survive and resprout, and the main crop on most cold-climate figs grows on new wood, so dieback costs time, not always the whole crop.

Set your zone, then open the fig tree page for a zone-specific line.

Fig Hardiness by Zone

Zones 9 and 10: Grows outdoors year-round. Mulch the base and skip late-summer fertilizer so new growth hardens before winter.
Zone 8: Usually hardy in the ground. A hard winter can kill tips or tops back. In colder spots, plant on the south side of a building.
Zone 7: Often dies back in cold winters and regrows from the base. NC State Extension notes figs may freeze to the ground at 20F or lower. Mound loose soil or mulch 1 to 2 feet high around the trunk in late fall and pull it back in spring.
Zone 6: Needs protection. Wrap and insulate the tree, or bend it into a trench and bury it. A potted fig moved into the garage is less work.
Zone 5: In-ground figs usually die to the ground. Chicago Hardy may regrow from heavily mulched roots in a warm microclimate, but crops are unreliable. A container fig is the dependable choice.
Zones 3 and 4: Container only. Store the pot in a cool, dark, unheated space for winter.

These zone notes match USDA zone lows to the temperatures above: zone 8 bottoms out at 10 to 20F, zone 7 at 0 to 10F, and zone 6 at -10 to 0F.

Cultivar Notes

Chicago Hardy: Missouri Botanical Garden lists stems hardy to about 10F and roots to about -20F. It rates the variety for zone 6 and warmer, and zone 5 in a warm spot with heavy mulch. Stems that die back resprout and fruit on new wood.
Celeste and Brown Turkey: University of Tennessee Extension lists Celeste as winter hardy to about 0F and Brown Turkey to about 10F. UF/IFAS also notes both are reported to be more cold hardy than many figs.
Vigor matters. UGA and Clemson Extension both advise cutting fertilizer in half where figs are often winter injured, because fast, soft growth freezes first.

Wrap and Cover (Zones 6 and 7)

Penn State Extension's method:

1. After a hard frost, remove remaining leaves and unripe figs. 2. Mulch the base 6 to 12 inches deep with leaves or straw. 3. Prune branches to a manageable height and tie them together. 4. Wrap with burlap, row cover, or another breathable fabric. Do not use plastic against the wood; it traps moisture and invites disease. 5. Encase the tree in cardboard and fill it loosely with dry straw. 6. Top with a tarp or an upturned bucket to shed water, leaving the bottom open for air.

Unwrap in spring once hard freezes are over.

Trench and Bury (Zone 6 and Colder)

1. Prune and tie the branches. 2. Dig a trench as long as the tree is tall. 3. Cut about a foot deep around the root ball so the tree can tip into the trench with its main roots intact. 4. Lay the tree down and cover it with plywood or cardboard to keep out mice and voles. 5. Cover with about a foot of soil, straw, or both. 6. Lift the tree back up in spring after hard freezes pass.

University of New Hampshire trials found that chicken-wire cages packed with chopped leaves gave nearly complete winter survival outdoors. The plants lost outdoors were killed by voles, not cold, so add a barrier at the base.

Potted Figs in the Garage (Any Zone)

1. After a hard frost, strip leaves and unripe fruit. 2. Move the pot into an unheated garage, shed, or cool basement. Darkness is fine because the tree is dormant. 3. Water about once a month, just enough to keep roots from drying out. 4. Do not keep it warm. Penn State notes figs need about 100 hours of chilling to fruit. 5. Move the pot back outside in April, or after your last hard freeze.

If the garage drops well below 20F, wrap the pot or surround it with straw bales.

Next Steps

Check your countdown on first frost date, tick the fig task on Garden to Bed, and see what to mulch before winter. Fig trees come from nurseries, not seed packets.
