BTW. If you cut that PVC elbow / insert fitting off at the pipe (save
as much pipe as you can) then use an 8 port manifold; would give you
8 drip lines in the small space. Make the runs as long as you like.

Look in a real local garden / nursery center and how it fits the pipe.

I had not even thought of that, but it has the advantage that
the drip lines would all radiate from the same point, so the
water flow should be even, right?

Yes you can adjust the drip head or adjust the flow at the manifold.

I have large tress )Palm and African Sumac) and Foxtail grass.

Is this foxtail grass sprouting up all over my lawn?

Can't really tell. Your's kind of reminds of "sea oats", but they
only grow on coastal beach sand dunes. Best I know.

This is what I call foxtail.

Ah, I see. Similar, but probably different.

My "stuff" grows wild in balls dotted all over the place.

Do they get the soft "plumes" in the spring or are they always the
same, as in your photo?

Chances are yours will have a reasonably shallow root ball. Easy to
remove if they bother you.

A local nursery will gladly help you identify them.
