A protectant and sealant solution and method of use thereof, configured to protect wood from premature decay when disposed in contact with the earth. The solution is composed of processed hemp oil which is mixed with bio-diesel and other oils to form the protectant solution. The wood is then impregnated with the solution via pressure treatment within a retort cylinder. The solution is configured to protect utility poles and other wooden construction members which are known for prolonged contact with soil. The solution is designed as a safe replacement for pentachlorophenol solutions which have been found to be harmful to the soil and water table.
