Two Euphorbia in pots on the back porch. Lots of sun, esp. summer.

Have never pruned a Euphobia, but need to learn how pretty quick.
From photo you can see how they are hanging tiredly down.

They get plenty of water.

Are they getting too much sun?

Will check Internet for Euphorbia (can't remember variety; does
anybody know)? but meantime would appreciate any advice.

This is So. Calif coastal.

TIA
