A telescopic leaf blower extension apparatus for extending a leaf blower hose includes a proximal tube that is configured to attach to a flex tube of a leaf blower. A distal tube is coupled to the proximal tube. The distal tube is telescopably coupled to the proximal tube. The distal tube has a retracted position within the proximal tube and an alternate extended position. A clamp means is coupled to the proximal tube and is selectively engageable with the distal tube to prevent the distal tube from moving between the retracted position and the alternate extended position.
