That is soaker hose, it worked so, so. We have very hard water and I think a drip line would be too expensive to maintain. I kept the ground clean of vegetation by just carrying a garden hoe everytime I walked around in the nursery and removing anything I saw sprouting. I was actually quite surprised it looks as clean as it does.
Thanks everyone for the compliments, it was a enjoyable undertaking and I am looking forward to the next growing season.
