I follow the notion to use fewer 1/4" tubes in the 1/2" poly. The
more holes you pierce in the 1/2" adds to potential leaks. It cuts
water flow a bit, but the tube drip heads can be adjusted to
compensate. Or run it longer on the timer.

The 1/4" can be "teed off" the main drip line with barbed fittings.
Easier to fix than a 1/2" pipe with 10 holes in it.

I put in my front yard (desert) a manifold. Tubes run from it.

Each line can be adjusted for water flow.

Given your small space I bet the manifold (4 port) would be best.

I forget if the manifold is threaded into an old sprinkler head tee.
You get the idea.

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.

I was wondering about that.

Why doesn't anyone just take a length of 3/4" PVC
and drill a few holes in it?

Seems to me the cheapest and strongest method.

I guess the only downside is you need a drill press
to make it efficient.

Ever see the outdoor misters? Same idea but the mister heads clog from
hard water minerals. For a lawn irrigation system, PVC is to rigid for
a drip line system.

Ah. Thanks. I had never seen those before.
My water is somewhat hard (I think it's 14 ppm Calcium.)
Certainly the coffee pot gets that white film in just a week (removed with vinegar).

Mister systems are used in the desert. Homes and restaurants with
patio dining areas.
