Hello Hodge,
Normally one dripper head per plant....a one gallon per hour driphead. They come one gallon per hour, two gallons per hour and four gallons per hour.
I have a huge boxwood in a training pot that has a four gallon dripper on it and a very large elm in a bonsai pot that has two drip heads on it, I believe they are two gallon drippers. But most of my junipers in bonsai pots have only 1 one gallon dripper on each plant. You need to play with it when you get it set up, if you use the timer, how long will you set the water to be on, how many times a day or a week? What ever seems to work for you.

Now that the winter is here I am only watering for 30 minutes twice a week.
This summer I will probably water for 30 minutes twice a day, every day.
Hope this helps.
