Recommended sprinkler or drip setup

Good morning. I was wondering what might be the recommendation for watering a little over 100 4x9 tree pots in a small footprint (about 20 square feet) might be.

I was thinking about a yard sprinkler as there is one on Amazon that supposedly can be pretty finely controlled/contained to a small area. In the past I have used micro spray sprinklers from Lowe’s and spot spitters. It seems like the spray from those gets blocked over time by vegetation as the plants grow so I was leaning towards over head irrigation this time around.

Any thoughts are appreciated.

Thanks,

Matt

I found a little cheap system on e-bay for $20. Comes with pressure reducer, hose, and a lot of little spray emitters that go in each pot. About 200 foot of hose and you just cut the hose where you want an emitter to go. Cheaply made, but good for $20.
