But what can you do if your only sunny spot borders the road (as it does for me?) Plant a barrier.
I planted a row of spirea and lilac bushes to shield my garden from the road salt and pollution that inevitably finds its way into our lawn.
Is it perfect? No. Does it take some of the salt and pollution? Yes. Does it steal some of the sunlight? Yes. You will need to plant hardy low-lying shrubs and be vigilant about pruning. Does it also attract pollinators? Yes. Choose shrubs that flower. They will attract more bees and beneficial insects.
