Plugging The Leak is not really fine tuning, but before we can fine tune — or indeed, before we can do anything more on The Aqueduct — we have to do it.
We thought the problem was the drain that enters the small holding pond below the driveway. We dug up a section along the edge of the drive, removed some perforated plastic drain pipe and backfilled with heavy clay soil. It wasn’t a big job and it took only a few hours. But it didn’t work.
We thought again. Could the cascade pond be leaking? (The cascade pond is the one surrounded by spirea. I showed a photo of it in The Aqueduct, Part 2: Building It ) We built the pond almost 15 years ago and it has worked perfectly ever since. Still, we could see that water was pooling on the driveway near the pond so we decided to investigate.
These yellow flag iris came out in a single clump. We’ll replant some here by the cascade,
and put others in wet areas near the Skating Pond in the upper field.
That is, if we can pry the clump into smaller pieces!
Moving the rock away from the pond was hard.
Putting it back in place will be harder still.
We repacked the edge of the pond with clay to prevent water backing up
into the drain under the driveway.
Unfortunately, this didn’t correct the problem either.
Resolving it is absolutely necessary. If we don’t, water will continue to run down the steps that lead to the front door. Not a good idea in summer, and potentially fatal in winter when frozen water would transform the steps into a ski slope.
Plus the excess water is killing my special plant, Jeffersonia diphylla. Losing this plant would create a gap in my heart that would be very hard to fill.
|My one Jeffersonia diphylla is not looking happy.
So neither am I.
I’m not sure what we’ll do next. This is discouraging because instead of enjoying The Aqueduct all summer, it is becoming a headache.
I won’t write about The Aqueduct again until we have solved the problem. I hope you will join me next week when I’ll write about England and some of the magnificent gardens we visited there.
