I’m lucky because, working from home, I can take a plant-watering break pretty much whenever I or they need it – but I thought it was worth asking for people who have to leave their veggies baking in their greenhouse all day without a comfort break.

Above ground sprinkler type things (like the one in the picture) are apparently very inefficient at watering veggies – too much of the water evaporates on the surface before it has a chance to get down to the roots.

I’ve heard of people using holey old garden hose as a makeshift drip irrigation system but that seems like it might be a little hard to manage the flow – in my mind, the question has a second part that didn’t fit in the headline up there: “how can I make a reused or recycled irrigation system that doesn’t waste too much water?”

Any ideas?

(It’s also important to consider preventative water-loss measures – mulching and the like – which cut down on the amount of water lost to evaporation — what’s your favourite reuse/recycle for that sort of thing?)
