Cypress Trees Submerged in Pond: Likely Dead

4 cypress trees (3 ft tall) planted in dry pond bed. Pond refilled, trees under 3+ ft water for a month. No sign of life as water recedes.

Tolerance Limit

Cypress tolerates short deep flooding (especially winter). Seedlings cannot withstand >1 month total submergence. Need foliage above water for photosynthesis.

Verdict

Almost certainly dead.
