Old gardening water hose needs repair. In the past, I used some kind of tape; it held up okay,

Hal Palowoda: its called a hose mender you can get them at any hardware store and it only takes a few mins to put it on and only cost like 2 dollars

Carter Edstrom: Its cheaper and less hassle to buy an new hose.

Cyndy Grimes: Silicon tape, available in plumbing departmets at home centers

Wilbur Marksberry: buy the cheapest hose you find, most will last a couple of years, but if you replace it every year, you won't have to fight leaks.

Estrella Northway: you can buy connectors at the hardware store
