there's a link to juniper care and maintenance. Maintaining a bonsai isn't too hard if you have the tree looking like how you want it, all you really have to do is water the plant regularly, re-pot it every few years and cut back any unwanted growth.
It helps to read up about the plant to understand how much direct sunlight it likes and what pests and diseases it's prone to.
Junipers like summer sun. Water it only when it's dry. They hate wet feet. Junipers are also outdoor trees. don't buy it and keep it inside or it will suffer and eventually die.
