About this time of the summer, as wave after wave of heat descends on the Pacific Northwest, I find I spend an inordinate amount of time at the end of a hose. So much so that I begin to feel that in lieu of arms, I have hoses. This year has been worse than most because I decided to turn off the irrigation system and water by hand.
Purposely not using the irrigation system may seem foolish, but much of the system needs to be revised and repaired. Rather than waste water shooting in the wrong direction, I’ve opted into the more time consuming method until we can make repairs in early spring.
What I’ve discovered is many plants didn’t need the amount of irrigation I had programmed. Often I was over watering an entire zone for the sake of one plant (i.e. Astilbe or similar thirsty plants). The entire driveway garden has not had any additional water this year other than the two cloud bursts associated with infrequent thunderstorms. The only plant that has suffered so far is a daylily up near the top whose roots mingle with a Douglas fir tree. I’ve decided that I will move that daylily to an area where it is not as dry and allow more Euphorbia characias wulfenii to seed in there, with perhaps some red-orange Kniphofia. These are two plants already in the bed that are doing well. Also included in the mix are Stipa gigantea, Eryngium giganteum (although I’m considering its purge due to its slutty ways…it is also known as ‘Miss Wilmott’s Ghost’), masses of orange lilies, carpet rose ‘Paprika’, purple asters, Blue Star junipers, Coppertina ninebark, Berberis ‘Sunjoy Gold Pillar’, Epilobum (Zauschneria), 3-Yucca ‘Color Guard’ in red-orange pots and a newly planted Callistemon. The border is about 5’ deep at the top, tapering to 2’ deep about 75’ down the driveway. Then is widens again as it gets beyond the property line row of arborvitae that my husband planted when we first moved here 24 years ago.
So while the rest of my garden gets pampered with additional water, this is one area that gets very little and still thrives.
