After it rains, our back yard takes forever to drain. It’s so discouraging to plant things and they drown. How can we get rid of the water without flooding our neighbors?
Drainage dilemmas plague many folks, either with seasonal sinkholes where water collects after a rain or a spot that’s always spongy and nothing grows well but weeds. Now we are talking shallow depression in the yard here, not hole-big-enough-to-eat-the-house-Florida-style.
Like a leaky roof, you probably don’t even think about drainage until it rains.
Landscaping professionals may disagree on HOW to solve drainage issues, but most agree the best solution financially and physically is to work with what you’ve got. Obviously if muddy waters rage through your yard like the Mississippi at flood stage – and you’re not interested in water-front property – you might need to a more comprehensive remedy. However, if your problem is periodic or simply a nuisance, here are a few inexpensive or even FREE ideas to try.
GRADE: Lawn grass responds best to a minimum 1/4″ drop vertically for every foot horizontal distance. That grade should point AWAY from your house, meaning soil at your home’s foundation should be the highest point. (Unless you live on a mountain, but that’s another post for another day.) Why? Constantly soggy soil means constantly soggy grass which means a lawn in constant distress. Expect diseases, especially fungal infection, and the pests that follow to become the dominant feature of your landscape if the slope’s too slight.
While pleasant to view, moss on a walk-way spells D-A-N-G-E-R! Raise the walk a couple inches and backfill with sand.
DRAINS: A “dry river” can be installed to quickly wick water away from your low spot.
River stones, if used in a dry river, must be large enough that they won’t wash away in a down-pour.
A bit of river rock, making sure it’s headed DOWNHILL, is an easy fix. But if the stones block instead of remove water, might as well invite the neighborhood over for a pool party next time a black cloud hovers. Water gushing down your river? A large boulder or clump of ornamental grass strategically located slows the flow. If the runoff is more than a dry river can handle alone, or if the area is not conducive to such a feature, consider a French drain instead of or besides. There are plenty of how-to’s online for French drains. If you hire drainage done, you might take the advice of a landscaper friend of mine when interviewing installers: “If you call in somebody to help with drainage and they don’t have a level in their truck, run ’em off!”
PLANTS: If the area is wet for a short time and not a nuisance, consider planting natives that thrive with wet feet, soaking up the extra moisture. Or how about creating a wildlife or bog garden, or even a water feature to take advantage of your problem? Check your local native plant society for a list of appropriate ones for your area.
One of my favorite plants for low spots is our native river birch, Betula nigra with its gorgeous peely bark.
Dual purpose, this container also holds rainwater runoff to irrigate the nearby veggie garden.
RAIN BARREL: At my house, rain barrels are going in at the gutter downspouts. When I build my new porch, I’m planning the roof based on collection of rainwater so my garden is self-sustaining when irrigation limitations come back, as they surely will.
Before you head for the big guns, be sure your plumbing or irrigation isn’t leaking and you’re watering properly. Then next time it rains, look for your low spots. Choose a remedy that will turn your problem on its head, making the area the HIGHlight of your landscape. Not so discouraging after all, is it? cc:
