not directly greening the desert but.....
we want to plant some trees and bananas over the weekend and we won't be there for several weeks. So how to water? It is NOT a dessert climate but warm temperate with decent rainfall it's summer here.
My first idea was these spikes from Bunnings which you screw onto bottles but apparently, they are NOT working at all. webpage
Any other ideas? Anything DYO which is low tech and does work?
