August to-do’s

In case you haven’t been keeping track, summer is winding down. True we will be enjoying great weather for months to come but nature uses daylight hours to mark its calendar. And even though I’m busy visiting reader’s gardens, camping, hiking and painting there are some tasks I need to in my own garden.

Around this time of year, annual and perennials in containers and hanging baskets can become leggy with flowers only at the end of long branches. At the same time, overly rambunctious growers can overwhelm neighboring plants, crowding or even suffocating them for lack of light and air.

Renew them by cutting back about half of the stems 2/3rds of the way to the base. When those stems grow back and begin to bloom in about two weeks, cut back the remaining stems the same way. While you’re at it, cut back aggressive growers as far as necessary to give surrounding plants space for healthy growth. Fertilize with a soluble plant food to keep them blooming through October.

Deadhead flowering annuals and perennials in the ground as often as you possibly can. Annuals like zinnias and cosmos will stop blooming if you allow them to go to seed. The same is true of repeat blooming perennials like dahlia, scabiosa, marguerites and lantana.

These plants know they’re on this earth to reproduce. If they get a chance to set seed, the show’s over- they’ve raised their family. Try to remove fading flowers regularly and you’ll be amply rewarded.

Fertilize shrubs lightly one last time in August or September if you haven’t already done so this month. All shrubs, especially broad-leaved evergreens such as rhododendron, pieris, camellia, hebe, need to calm down, stop growing and harden off to get ready for the winter cold. Some plants have already set next year’s buds.

Roses especially appreciate a bit of fertilizer now, encouraging them to bloom another round in September and October. To keep them blooming make a habit of pinching and pruning off old flowers. Always cut back to an outward facing branchlet with five leaves. There are hormones there that will cause a new rose to grow much sooner than if you cut to one with only three leaves.

Here are more to-do’s for late August for this area:

Prune fruit trees that have already finished fruiting. Wait to prune others until after harvest, although many see summer pruning as a way to thin an overabundant crop.  Summer pruning opens the tree to light, producing bigger, healthier fruit. Overall summer pruning will slow the growth of a tree by removing energy wasting water sprouts, helping keep dwarf trees a manageable size.

Sow root veggies such as beets, carrots. leeks, onions and parsnips directly in the ground and start germinating cool-season veggies- broccoli, cabbage, cauliflower, chard, lettuce, and spinach -so they are ready to plant in mid-September.

Now that you’ve taken care of your chores reward yourself by adding perennials to your garden for color in late summer through fall. Good choices include aster, chrysanthemum, coreopsis, gaillardia, gaura, Japanese anemone, echinacea, rudbeckia, Russian sage, scabiosa, Mexican marigold, verbena ad yarrow.
 
Blooming shrubs  that will flower well into fall are abutilon, blue hibiscus, butterfly bus, cape fuchsia, plumbago, lavatera, princess flower and salvia.

Wildflowers of the Sierra Nevada Mountains

I’d heard stories about the glorious wildflower displays in the Sierras, especially this year with all the snow melt, but nothing could prepare me for how many beautiful sights I would discover on the west side of Lake Tahoe last month. As I explored and hiked the forest trails I thought of what it might have been like to be an Native American from the Washoe tribe. How did they use some of these plants and would I find similar species used by our local Ohlone tribes?

I sketched, photographed and identified ( or tried to ) over 49 different wildflowers and admired many more native plants, trees, shrubs. The weather was  perfect for hiking and the sky as blue as the water of the lake.

Lake Tahoe and the land surrounding the lake were once home to the Washoe Indians who wintered in Carson Valley and spent their summers on the shores of the lake hunting, fishing and gathering food for the winter. I’m sure they admired the flower displays as I did.

Red-twig dogwoods bloomed along streambanks. Native Americans used the berries as food, both fresh and dried and cooked. The berries were eaten to treat colds and slow bleeding. The inner bark used as a tobacco either by itself of mixed with manzanita. The bark could also be used as a dye. The wood used for bows and arrows, stakes and other tools.

Pink Sierra currants sported beautiful pink flower clusters and edible blue-black berries. Tribes relished the berries fresh and dried them for later use in the winter. All species in the genus, including our own native canyon gooseberry, have berries high in vitamin C. When dried they were mixed with animal fat and eaten while traveling.

Wood’s roses were in full bloom, their dark pink flowers fragrant in the sun. A variation of the species grows in every western state and throughout Canada. The petals can be eaten raw after the bitter white base is removed. The seed or rose hip contains 24 times as much vitamin C as oranges, vitamin A and E and is also a fairly good source of essential fatty acids, which is unusual for a fruit. A poultice of chewed leaves was used by Native Americans for bee stings. Various parts of the plant were used to treat burns, sores, swelling and wounds and used to make tea-like beverages. All this from a plant that is beautiful, too.

A real looker, the Mariposa Lily caught my eye. Blooming along the trail to McKinney Lake, I thought of how the Washoe would consider these plants a great find, digging up the sweet bulbs to be eaten fresh. We almost missed the Sierra tiger lily mistaking it for the columbines that were nearby. Their orange flowers are much larger but both are stunning to see in the moist meadows.

Other flowers that I encountered were monardella, penstemon, yarrow, lupine, larkspur, arnica, thalictrum, snowberry, giant hyssop, aster, solomon seal, corn lily, mimulus, paintbrush, western burning bush, cow parsnip, wintergreen, phacaela, golden rod, epilobium and sidalcea to name just a few. I was in seventh heaven.

I loved seeing all the rein orchids that were in full bloom. Pine drops emerged from the ground with their urn-shaped downward facing flowers. Plants exist for most of their life as a mass of brittle, but fleshy roots, living in a parasitic relationship with mycorrhizal fungi from which they derive all their carbon. Another unusual plant I saw, pushing up from the ground was the bright scarlet sarcodes or snow flower, a parasitic plant that also derives nutrients from mycorrhizal fungi. Nature has come up with many ways to survive and these are but two good examples.

Native Americans used grasses and pine needles for baskets, willows for household goods, acorns from oaks as a food staple as well as for dyes, medicines, games, toys and construction materials and wild onions for food and flavoring. I’m sure they loved to see the wildflower for their pure beauty as I did.

 

How to Combat Moles and other Critters in the Garden

There’s a gentle guy among us with a beautiful garden in Scotts Valley who’s a serial killer – a killer of moles, that is. "The first one’s the toughest"  he said while showing me around the other day. Caddyshack has nothing on this determined gardener and from the look of his landscaping he’s definitely winning the battle.

This mild mannered vegetarian started planting trees 20 years ago when he moved to the property but says he became serious about gardening only 5 years ago. He has created lush-looking, low water landscaping in his extremely sandy soil, watering some areas only once per summer. And oh, did I mention, he shares his garden with deer, too?

Many of us battle some of these same issues. How does he win the war while watching his garden grow? He used to have gophers, too, but after using cinch and Macabee traps for the past couple of years there are not too many left on the property. The moles are a different story. They have the ability to learn testing our mental prowess in the process.

He has found that one of the best ways to keep moles from destroying his garden is to install perimeter fencing around the beds. Gardening by exclusion he calls it. Cinch traps are successful, too, and he’s killed 16 so far this year. It’s not that the moles eat the plants but their burrowing dislodges roots and the plants will die the next time it gets hot. He digs down 24" and sinks a gopher wire barrier, one area at a time.  Paths are left bare so he can see if they are encroaching. Moles can tunnel 17 hours a day and ruin an area in just a couple of hours so he has become ever vigilant.

Deer control comes from plant selection and a product he gets on the internet that contains a bittering agent found in antifreeze, anti-nail biting and cleaning products among other household items.  Having used other taste and smell repellents containing rotten eggs, garlic, blood meal, citrus, ammonia, hot pepper and coyote urine, he swears by this product. His garden contains many plants he considers "bullet proof" like lambs ears, lions tail, hot lips salvia, breath of heaven, tagetes, armeria, asteriscus, carnations, dietes, Little John callistemon, mimulus, westringea and society garlic to name just a few. He plants "what works".

What hasn’t worked with his deer population is vinca that used to grow under the oaks. Wandering jew has successfully taken over and he’s OK with that. "Why fight it?" is his mantra. Plants he protects with Bitrex are daylily flowers, star jasmine, correa, penstemon, some sedums and the flowers on the aloe. He grows lots of different aloes, yucca and agaves, rescuing many from garbage piles and propagating others. He has 4 acres to cover.  There’s also a huge Angel’s trumpet under the oaks that he started from a cutting 4 years ago.

In one garden a huge Breath of Heaven has grown 9 ft tall. Nearby is a handsome small tree from So. Africa, Podocarpus henkelii or Long-leafed Yellow-wood. Eventually it will grow to 25 ft but is only half that size now. The foliage is distinctive and dense with heavy, shiny, dark green drooping leaves, giving it a weeping look. It is truly a specimen tree. His euphorbia collection includes a variety that looks like an azalea with chartreuse flowers. A very large stand of crocosmia was started from a 4" pot. Fortunately it’s planted in the right spot.

So much to see, so little time. Everywhere I looked was another beautiful vignette- accenting a dry river bed in one area, a fire pit with log seating in another. I learned so much from this gentle, determined gardener.
