There seems no way to have saucers under the pots, so on a hot day, they'd dry out in no time. Even with trickle irrigation, you'll use a ridiculous quantity of water to keep anything alive, ( other than plastic )
That’s a good shout actually Hostefan1. I’ll keep an eye on water usage. I wonder what plant could trail well but not be so thirsty (is the proper term hardy? - tough? )
