Without a picture it's difficult to ascertain what issue is occurring, if the paint is peeling etc it could be lack of preparation of the wooden surface, priming, sanding.
Are you painting on top of already flaking paint? If so the loose stuff all has to come off before you paint again.
Could be wrong type of paint used, generally an outdoor wood paint that claims to last 5 years will last 2-3 dependant on climate.
Are you painting damp, old, rotten wood? If the wood is damp, moisture will be trapped and cause poor paint adhesion, blistering etc.
