Saving a Split Forked Oak Tree

35-year-old oak split near ground (forked trunk), smaller half removed. Owner wants to save remaining half.

Cause & Prognosis

Forked trunks create weak attachment (included bark). Weight of canopy caused failure. Remaining fork can survive but will look lopsided for years.

Care Plan

1. Clean wound: Remove loose bark/splinters smoothly.
2. Apply tree wound dressing (exception to usual advice) due to large wound size.
3. Monitor for borers (sawdust/holes); treat with Onyx if detected.
4. Fertilize: 10-10-10 at 1 lb per inch trunk diameter for faster canopy fill-in.

Consult state forester for on-site assessment if concerned.
