My Pile: Chipping Away

With a sprawling load of shredded wood and leaves parked in my driveway, I know what I have to do this weekend.

After Saturday morning errands, I haul the wheelbarrow from behind the backyard shed and load into it a set of tools – the wide-tined hay pitchfork, two rakes and the wide-brim shovel. I wheel them to the front of the yard and set up shop beside the mound of tree mulch, already steaming with the raw, aromatic scent of sap and fermenting wood pulp. It’s easily the largest load I’ve ever had to tackle.

Digging into the massive wood-chip mulch pile, which I'm relieved to find is actually a fluffy mix of leaves and shredded sawdust and sycamore balls.

I feel somewhat silly for accepting the chips without first peering into the covered dump truck to see that not only did it contain the diced-up remains of my tree trimmings but also that of a previous job. I eyeball the pile before me, and mentally attempt to parcel it out across the perennial beds that ring my property. Just thinking about the work ahead is tiring. I glance up the street and wonder who among my neighbors I can pawn off the excess chips I will surely have after covering every square inch of my available ground. Spreading wood-chip mulch is both a physical and mental exercise.

I think back to the many other times and seasons I’ve accepted a load of fresh wood chips from a crew working nearby and know I’ve thought the same. A large pile of anything you’ve suddenly got to dispense with always looks daunting; massive and seemingly immovable. But volume measured in cubic yards invariably becomes manageable when spread across a lot of square feet. Picture an above-ground swimming pool filled with water. It bursts, and the water spreads out across the ground and is gone. That’s the same with spreading wood chips across the garden beds and other weed-free places on my tidy suburban property. Call it sheet composting, for I’m taking a heap of freshly dead organic material that dwarfs my pile in size and spreading it across the ground where it will over the coming year decompose straight into the ground. It’s a pop-up version of my pile; here today, gone tomorrow.

Such mental gymnastics helps but doesn’t change the fact all those chips won’t move themselves, so I lean the wheelbarrow against the steepest side of the mound of chips and plunge the hay pitchfork into the peak of chips above it, using gravity to fill the wheelbarrow with several scraping thrusts.

Last spring I spread a small load of chips under the row of forsythia bushes along the side street and across the back fence of my property. The largest stretch of planted garden, along the western side of my yard, is bereft of chips. I spread much of last year’s finished compost across the rotting wood chip mulch of the year before, and now the ground is covered with the end result: Deep, loamy, newly minted soil. If I don’t blanket the perennial beds this fall with a layer of fresh chips, come next spring bare ground will surely grow in thick with weeds that I will have to laboriously have to evict by hand and trowel. Funny how striving for a low-maintenance garden involves so much work.

I start by dumping whole wheelbarrows full of wood chips in the spaces between the perennial plantings of ferns and seasonal flowers as well as the azalea, rhododendron, rose of sharon and butterfly bushes that take up their own separate spaces along the border garden, a curvaceous stretch about 110 feet in length that ranges from five to 15 feet in width.

I’m pretty efficient at working a pitchfork, shovel or rake to load the wheelbarrow with wood chips. It’s easy lifting, when you get down to it. Most of the energy expended is in the transport. I schlep a dozen or so wheelbarrow loads to dump across a section of garden before stopping to rake out the tidy piles to cover the bare ground with a meringue of mulch, taking care not to bury the perennials. I strive for a depth of 4 to 6 inches; enough to keep the weeds at bay without making life to difficult for the many bulbs of daffodils and crocuses that are buried beneath. All the while, I make the mental calculus of figuring out how much ground I’ve covered against how big of a dent I’ve made in the mound of chips blocking my driveway.

In years past, I’ve spread chips made almost entirely of chopped-up tree trunks and branches, harvested after the leaves have dropped and the sap has been chased underground by the cold. But this batch, I’m relieved to realize, is a fluffy, airy  mix of fresh tree potpourri, suffused with shredded leaves and diced sycamore balls, nearly as light as cotton candy. I spread it more thickly than usual, knowing that the shredded leaves will soon condense themselves into a matrix of leaf mold and wood chips, flattened by rain and further stitched together, first by frost and then by freezing ground.

Besides, I enjoy the manual labor, working up a sweat wielding a wheelbarrow and the business end of a pitchfork and rake on a pleasant fall afternoon in late-October. It’s a weekend warrior’s workout, and  a good one at that, if a lost practiced art in the age of the leaf blower. It’s also a hike, all that back-and-forth muling. I spread another dozen or so loads, dumping the wheelbarrow in the spaces between plantings, then raking it all in. The leaves on the trees in my yard are just now peaking in color, and I have figure I have just enough time to finish spreading the chips before the major leaf cleanup begins.

By evening time on Saturday, I’ve covered about half of my long garden bed of perennials along the western side of my yard and figure I’ve used up about a third of the pile of chips. I’m working on a tight timeline. I have just Sunday afternoon to scatter the wood pile, as the weather forecast calls for heavy rain midweek, as much as two inches, the first significant rain of the month. As easy as it is to load, haul and spread a feather-light mix of wood chips and pureed leaves, I don’t fancy shoveling up chips soaked with all that rainwater.

On Sunday afternoon I power through the rest of the pile, layering the rest of the flower beds with a four-inch covering of the minced mulch, and dumping wheelbarrows wholesale along a shallow ditch between my back fence and bed of ferns and hostas. The lowest part of my gently sloping property, the ditch briefly fills with water during the heaviest of rain storms. It makes a fine refuge and final resting place for a thick layering of wood chips left to rot.

The small culvert that runs along the back fence becomes the repository for much of the chips, which will soon decompose in the shady, damp environs.

By late Sunday afternoon, I’ve packed up the tarps and used the leaf blower to scoot the last flecks of chips from the gravel driveway. The garden beds are now cloaked in a mesh of fresh chopped mulch.

My pile has benefited as well, for at the bottom of the mulch pile were pockets of ground-up leaves, masticated sycamore seed balls and pure shavings of sawdust. I add two wheelbarrows of the fluff straight onto my pile.

I glean several wheelbarrows of minced leaves, diced sycamore balls and chain-saw sawdust curlings to add straight to my pile.

I’ve kept the remains of my own tree trimmings on the property, and the yard has absorbed much more decompostible organic matter from somewhere nearby. If and when the rain comes, it will soak deep into the mulch beds and settle in place, making the coming fall cleanup of leaves that fall onto the beds that much easier. I’d salute myself in triumph for a backyard gardener’s job well done, if I wasn’t so tired to lift up my arms.
