I don't know about you all, but when the temperature regularly exceeds 100 degrees, and it hasn't rained in a millennium, and the water-well breaks down, I stop with the gardening. About the only thing I've done in the last two or three weeks is triage on some of those woody plants whose leaves are turning yellow or crispy-dead. Amongst my perennials, the southern species of wild ginger Asarum arifolium, known colloquially as 'little brown jugs,' is my number one indicator species as it always tells me when things are getting critical. I can not explain why that particular species tugs at my heart so. That and Triosteum pinnatifidum, which is an asian counterpart to our native 'orange-fruited horse-gentian,' which certainly has the silliest name of anything that grows in Michigan, particularly since the plant has nothing to do with horses or gentians. Where was I? Oh, right, there's not much left of my asian h-g but I'm giving it water anyway. Fortunately I had broken off a piece earlier in the season and located it somewhere where the soil hadn't been ruined by earthworms.
So let's talk irrigation. What's the best way? Please chime in. I've tried hardware-store soaker hoses but they spring random leaks and squirt in random directions, and it's just about impossible to get the flat ones to make turns. This year I bought 1/4" plastic tubing from Loews, into which one can poke holes with a special hole-poker. You then insert an overpriced reducer into each hole so that it delivers a specified small number of gallons per hour. A section of 1/4" flexible vinyl tubing (which is available in various shades) can be attached to each reducer and extended to the plant that is to receive the drip. It's one tube per plant. Or you can link a stretch of vinyl tubing to a weeny elevated 'sprinkler' head and maybe reach a couple plants. That's my experience with it so far. It definitely does the job with great efficiency, but you can only buy the reducers in expensive little 4-packs. My next goal will be to find a better source where these things can be bought in good quantity. I'll start with A.M. Leonard (www.amleo.com), where you can buy components in packages of 100.
And, by the way, this picture was taken with my i-Phone with a lens attachment that allows for close-ups and fish-eyes. As was the following . . .
