Here’s a video of the basics of drip irrigation. I highly recommend buying Dripworks.com products as they are very easy to use, durable, and the customer service is excellent.
Buy the Heart of the Garden Kit and add on the Drip Emitters Kit and you can water up to 50 plants. The kits can be used for years and years and adjusted to any type of garden. You can get a lot fancier like my garden, but the basic kit is really a good place to start.
