Rain Garden

 Much of my gardening is driven by changing light conditions - trees grow, trees fall, buildings are built, and the light changes. When the giant spruce fell in my yard in March 2018, conditions changed substantially and the ripple effect continues. 

Peculiar blossoms and fruits

I had a Carolina sweetshrub bush, bought and planted in the waning days of the last century, in front of my house. It was one of several bushes planted in a little thicket beside the walk to my front door, deliberately to create privacy and block views from the street into my house and yard. I only put in shade-adapted natives: the sweetshrub, several blueberries, shadbush, dogwood, oakleaf hydrangea, arrowwood viburnum and cranberry viburnum. For almost two decades the Norway spruce overtopped them and provided shade from deep to dappled, and so they all poked along, establishing roots, growing slowly, intertwining as they way. When the spruce fell, the brakes came off! Now, it is a thriving deep dense thicket, ripe with berries and caterpillars and thus a prime bird habitat.

The sweetshrub, planted at the end of the thicket, was a real winner in the light-and-water sweepstakes. It turns out, this bush can spread by sending out underground suckers, creating a thicket all its own encroaching both on the other bushes and the lawn in the other direction. I realized by the year after the tree fell that it was dominating the space and might have to go. As I thought about it, I grew enamored of the idea of making prime full-sun space available for a rain garden. But it would be a considerable project. 

I dove into the thicket periodically to methodically dig out suckers, beginning with the ones farthest from the main bush. A few of the suckers I transplanted to the opposite end of my yard where there is currently deep shade. Last year, I got the size of the bush down to maybe three feet in diameter, and cut it all off to about four feet high. I kept eying the standing corpse and dreading the task of digging it out.

It's ripe for the plucking!

Houseguests to the rescue! Last October my boat partner and her husband vacationed in my basement for a week (almost as nice as their aborted trip to the Azores, no?)  And one lovely day while they were staying, my sailing partner and I indulged ourselves with weekday sailing, leaving her prone-to-seasickness husband to stay behind and work on his book. But, he asked for anything that needed doing outside. I suspect he wanted to mow the grass, but I pointed out the bush and where the tools were kept, kind of as a joke. But we came home to find the bush gone, all of its sticks bundled for removal and the roots out of the ground, a tidy hole in the ground left behind.

Waiting for next steps

All spring I worried over what to do next. I had spoken to a local contractor about doing a rain garden project, but he never pursued me and I'm past begging for folks to come do work I could do myself. I knew I had to dig out the space, connect to a buried drain from the roof gutters, modify the soil, buy lots of plants. It seemed a big and daunting project, and I did nothing about it. Every time I walked past the scar left behind it gnawed at me.

But, the kedge (planning a big difficult trip to make myself get in better shape) worked! In fact, not only am I in better physical shape, but mentally I'm more ready to tackle difficult things. And, once I got into it, making the rain garden was very manageable.

So, I dug out the space.

I modified the soil.

 

I bought some plants and put them in. It needs more plants, but July is not a great time to acquire plants - spring ones are gone, fall ones are not in. Some things I wanted are not available, and I may end up shopping my yard to move some things from elsewhere. Fall is a great time to do this.

I mulched the heck out of it.

Finally, we had some rain and I was able to watch as rain from the roof drained through the pipe and into the garden, where it filled up and then drained slowly over the course of some hours just as planned!

The one sad thing is this is still the deer highway where they come from the creek into my yard (to eat all my apples). So far, that hasn't been an issue with what I've put in. I'll continue to look for less appetizing plants.

EDIT: As it turns out, last night (evening of the day I wrote this) we got 1.5” of rain in 25 minutes! Towards the end of the downpour (when I thought it was safe) I went out to look. There were a good 6” of water in the rain garden throughout the bowl, with active draining from the roof. When I went out about three hours later, it had all drained away. Exactly the way it’s supposed to work!
