How can I make my strawberry plants become big and healthy?

plant in raised rows, so there is a valley between rows.

You cannot get any water on the plant itself it must go into the ground .

When you plant them, dig the valley and raised rows and lay construction plastic on top of the raised rows where the plants will go and cut a hole for the plant to go in.

Then cover all of the ground with hay. This is the perfect way to grow great strawberries. The plastic will also keep the berries off the ground when they get heavy.
