Sometimes, we start our garden design from a patch of dirt. Sometimes, we just tidy up existing gardens. We update the irrigation, add fresh plants and mulch, and maybe lighting. This garden got a makeover right before the winter holidays, and our happy client sent us the email below.
“I’m sitting in my little office which looks out on the garden, and it is just so beautiful I had to write. The sights and smells out there are divine, and yesterday we were visited by a mob of butterflies that I think are Painted Ladies! I put in some Mister Lincoln roses, who seem really happy here, and I’ve pruned the guava “tree” down to large-bush size, which will suit the garden better. The Anna apples look wonderful and both the Redbud and Pomegranate seem to be thriving. I will send pix around Eastertime when all is in bloom. Meanwhile, thanks again for a lovely job! Warmly, Susie
Lots of rain this year in Los Angeles! We’ve been installing rain gardens all over the Eastside for several years now. It’s been fun watching them fill during the storms. Instead of rushing into the city storm drains, and then straight to the ocean, this nitrogen-rich, chlorine-free storm water is harvested in the gardens. It is quickly absorbed into the garden soil, where it will be available to the surrounding plants and trees as they need it for months to come. Here are photos of some of the rain garden swales we’ve installed…
Downspouts connected to drain line (blue line) and into swales
A perfect pair, designed to match the home’s foundation, planted with Australian Willows.
A larger rain garden, full here. Water was absorbed by the next morning.
All three gardens, above, harvest water from the roof gutters. We connected downspouts to the swales via underground drainpipes. Now the water is dispersed and absorbed. Extra water will filter through the soil into aquifers.
To calculate how much water you can harvest, estimate the square footage of your house footprint. Divide that by 12 to determine cubic feet of rain, in a 1” rainstorm. Then multiply that number by 7.48 to get the number of gallons of water falling on your whole roof in an average 1” storm. Note that LA gets between 5” – 30” of rain/year, averaging 15” annually. You can also divide the roof into the sections that feed each downspout to calculate the number of gallons per downspout.
We found this little Mouse-Eared bat sleeping outside a garage in Seattle, a few summers ago.
Recently, a client requested a bat-friendly garden. We’ve designed kid-friendly, dog-friendly, bee-friendly (and un-friendly for bee-allergic), and certainly bird & butterfly-friendly. Bat-friendly was a new one!
Bats are helpful predators, eating insects we don’t want in our gardens. They eat mosquitos and other pests, including scorpions and roaches. They are also effective pollinators.
Adding bat boxes, a water source, keeping big healthy trees and shrubs for perching all encourage bat visitors. Plants that bloom and/or release fragrance at night are enticing, as are plants with pale blooms and broad open flowers. Brugmansia (Angel Trumpet) is topping my plant list, followed by California Evening Primrose. I’ve seen one in my garden, visiting my large Solandra maxima (Cup of Gold Vine) flower
If you still have a lawn and want it evergreen, but using as little water as possible, just add clover. Hopefully, you’re already maintaining your lawn organically (no chemical fertilizers or herbicides or weed&feed) and grasscycling. If you look closely, you will probably find some clover there already, probably in the really green parts. If not, you can overseed any part of your lawn that is looking bare/brown/patchy with Dutch White Clover seed. You can also top with some compost for good measure, but no need to go crazy with stinky manure.
Clovers, like legumes, (and with help from their little friends, in the soil) pull nitrogen out of the air and bring it into the soil, where they share it with the grass. Free, natural, bio-available fertilizer. That’s why the grass growing with them is super healthy.
You can order seed online (it’s cheaper than fertilizer!), and just scatter some around your yard, especially where it’s looking unhappy. Water it regularly for a week or so and watch your grass turn super (lucky) green.
We wrote this with G3 for the City of Beverly Hills, our 3rd handbook collaboration. All three handbooks explain the Watershed Approach to sustainable garden creation, remodeling and maintenance. They each contain extensive “How To” chapters, as well as sample designs and regionally specific plant lists.
This handbook address the various architectural and garden design styles of Beverly Hills. Update your garden sustainably while making it more beautiful and aesthetically harmonious with your home. Hope you enjoy it!
We helped G3 (Green Gardens Group) write this handbook for the San Diego SLP. Click on the link below for the full PDF.
The Sustainable Landscapes Program partners have produced a comprehensive, 71-page color guide entitled San Diego Sustainable Landscape Guidelines which details best practices and recommendations for a watershed approach to landscaping.
