Steps
Check the crack in dry weather. Note how deep it goes and whether the bark edges are loose, wet or dark, since rot means you need to cut back further.
Sterilise your knife or chisel with rubbing alcohol or a 10 percent bleach solution before you touch the tree.
Cut away loose, dead and torn bark around the crack with a sharp knife. Shape the cleaned area into a smooth oval so water cannot pool in a corner.
Stop at the green cambium layer. Do not gouge into the solid wood underneath, and leave healthy bark at the edges of the oval.
Wipe the exposed wood clean and let the surface dry for a few minutes before sealing.
Paint a thin coat of tree wound sealant or grafting wax over the whole cut face, pressing it into the edges so no bare wood shows.
Wrap the trunk with tree wrap from the base upward, overlapping each turn, and tie it off loosely so air can still move.
Or paint the south and west sides of the trunk with white latex paint to reflect winter sun and prevent new sunscald splits.
Clear grass and mulch away from the trunk base and water deeply before the ground freezes so the tree goes into winter hydrated.
Check the wrap and sealant in early spring. Remove the wrap once frosts end and reseal any reopened cracks.
Tips and common mistakes
Never seal a wet or rotting wound, because trapped moisture feeds fungus and can kill the tree faster than the crack.
Do not use household paint or tar as a sealant, since they can damage the living cambium layer.
Wrap only for winter and take it off in spring, or the trunk stays damp and invites pests and disease.
A crack that runs deep into the heartwood or oozes dark liquid is a job for an arborist, not a DIY patch.
Questions
Can I just leave the crack alone until spring?
No. Frost and water get into an open crack over winter and split it wider. Seal it in autumn before the first hard freeze.
What is the best sealant for tree bark wounds?
A commercial tree wound dressing or grafting wax works well. Avoid tar-based products and ordinary house paint on the cut itself.
Why did my tree bark split in the first place?
Usually sunscald on the south side, fast growth after heavy feeding, or a sudden hard freeze. White paint and steady watering help prevent it.
