We recommend to always test your lines to make sure that each plant gets adequate water.
This is an example of a drip system we used in front of our nursery. You run a 1/4" line and then run drip lines to each plant.
Here we have some Blue Fescue being watered by a very efficient drip system. You run 1/4" line along the plants and have an emitter placed where each one has been planted.
