Treats & Tips for the September Garden

salvia_m_Hot-LipsYou can feel the weather changing as summer winds down. It?s more than just the passing of the Labor Day holiday and the school year starting. The nights are longer and cooler. The days are not quite so hot and the flowers in the garden seem brighter and more colorful. I look past the soft blue and lavender blossoms and am drawn to the warm shades of gold, rust, orange, hot pink and red. They shout autumn is on the way.

There?s nothing quite like adding a few new perennials to brighten up the garden. There are many that don?t require a lot of water after they become established. I recently visited a garden where the irrigation was reduced to the point that that most of the plants were barely hanging on. But there among the crispy plants were two Hot Lips salvia blooming as big as you please. This plant is popular for a reason. Hummingbirds, butterflies and bees love it and it blooms for a long time. It stays compact and is a great carefree shrub for water wise gardens.

Daisy flowers always bring a smile to my face. As members of the composite family they have echinacea_Wild_Berrya flat landing surface for butterflies to land on. Coneflowers are one of my favorites. When they start blooming in the early summer I enjoy them both in the garden and as cut flowers inside. Some have a slight fragrance. Hybridizers have introduced beautiful shades of gold, yellow, orange, burgundy and coral in addition to the traditional purple and pure white. Because they are dormant in the winter they are good candidates for the garden that has summer sun but winter shade. They are not attractive to deer and are good additions to the low water garden.

gaillardiaAnother perennial that blooms throughout summer and fall is gaillardia also known as blanket flower. I?ve seen this tough plant grow in neglected gardens that the owner swears does nothing to keep it going. They are covered with dozens of large reddish-orange flowers with yellow edging and bloom over a long period. This plant also attracts butterflies. You can start perennials from seed at this time of year for next year?s bloom.

Don’t overlook the color of other foliage plants like Orange Libertia, Abelia ?Kaleidescope?, New Zealand flax, red fountain grass and Japanese bloodgrass in the garden.

Now through October, divide summer blooming perennials like agapanthus, coreopsis, daylily and penstemon that are overgrown and not flowering well. You can also divide spring blooming perennials like candytuft, columbine, astilbe, bergenia and bleeding heart but sometimes they don’t bloom the first spring afterwards due to the energy they use re-establishing themselves.

Another thing to do while out in the garden this month is to cut back berries vines that have produced fruit. Canes of the current season should be trained in their place.

Spider mites are especially prolific during hot, dry weather. Sometimes you don’t even know how bad the infestation is until all your leaves are pale with stippling. Periodically rinse dust and dirt off leaves with water. Spray the undersides of infected leaves with organics like insecticidal soap switching to neem oil if they build up a resistance to one of the pesticides.

Soon it will be time to start cool season veggies or plant cover crops in the garden. It?s never too soon to start planning for erosion control in those areas that caused you problems during last spring?s storms. But for now add some early fall color and have fun in the garden.

Traveling with the Mountain Gardener

Truckee_RiverSo far this year my travels have taken me up the coast of California and parts north. Then I headed a bit east to explore the Sierra Nevada. Statistics show that the drought is affecting all parts of the state. I?d heard that the Tahoe Queen had to modify it?s path around the rim of Lake Tahoe to avoid rocks. I had to check it out for myself. Just how low could that big blue body of water be? And what affect is the water situation having on the gardeners up there?

From the first glimpse of the Truckee river that is the sole outlet for Lake Tahoe I could see that the water was lower than usual. Still looked like enough water to negotiate a tube or small raft but the rafting companies have already closed for the season with the flow from the lake at only half of what it is normally in August. Hiking on the Tahoe Rim Trail next to the river was beautiful. The native plants and trees can exist even without the normal snowfall. They might not put on a lot of growth during dry years but they still looked healthy.

There is a chart at the dam where the Truckee river originates on the north side of Lake Tahoe. The graph shows that this is not the only drought event to have hit the Tahoe Basin. I was told the lake has been lower than this many times. Back in the 1930?s, 1962, 1976 and especially during the early 90?s the lake level dipped even lower. 2004 and 2010 were also low years. The lake level is just above the natural rim right now. The average daily evaporation rate of the lake is 397 million gallons.

In Tahoe City there is a destination nursery that I always visit when I?m in the area. In addition perennial_borderto several acres of trees and plants, the Tahoe Tree Company?s grounds are beautifully landscaped. A small lawn in surrounded by perennial beds loaded with flowers and a gazebo bordered with Autumn Joy sedum was just starting to bloom. Stands of quaking aspen towered over the shade beds of hosta, begonia, astilbe and New Guinea impatiens.

I asked one of the employees about how the drought has affected their customers. I noticed that many of the local residents had bright green lawns surrounded by dahlias, rudbeckia and ornamental grasses. She told me that many water companies serve the communities around the lake. They get some water from the lake itself but the rest is from springs which are drying up. The Tahoe City Public Utility District recommendation is to reduce water consumption by 20% with watering on even or odd days depending on your address.

Changes this season at the nursery range from reduced sale of seeds because seeds need regular watering to get started. Also customers are requesting more native plants but I was told that some of those requested are high water usage plants like dogwoods and willows. Customers are mulching more and learning which plants are drought tolerant. Popular natives include Sierra currant, Bitter and West Sand cherry, Mountain spiraea and elderberry.

Sun_King_AraliaStrolling the grounds of the nursery a brilliant gold plant caught my eye. Morning sun shone on a group of Sun King aralia and I had to find out more about this beautiful plant. In mid-spring this fast growing, 6 foot plant emerges with bright gold leaves. In sun the foliage remains gold through out the summer. In full shade, the foliage will be chartreuse to lime green in color. Spikes of tiny white flowers emerge in summer followed by ornamental black fruit. This plant is deer resistant. It?s needs some moisture so combine it with other average water users in the same bed.

We are all hoping this winter will bring us some relief from the drought, even those who live next to that big blue lake.

Add Drama to the Garden with Large-Leafed Plants

philodendron_selloumGardens have different personalities. Some gardens mimic nature with plants that attract birds and butterflies and other wildlife and look a bit wild. Some are neat and tidy with perennials lined up evenly along pathways and clipped hedges under the windows. All gardens are a reflection of their owners.? When I visit a garden to help the owner change, add or ?take the garden to the next level? I know which ideas will resonate with that person and which will just not work for them. Sometimes it?s easier for someone looking at a garden for the first time to visualize what?s needed.

Regardless of your style I often recommend one simple solution to update a garden. Many gardens end up with too many small-leafed plants. Nature is the master at this survival strategy. Small leaves are often more efficient at retaining water in drought conditions. When all your leaves are the same size, however, the garden gets boring. Using large, bold architectural plants allows the eye to rest on a focal point rather than try to take in everything at once, scanning back and forth.

Plants, like people, come in all sizes and shapes and so do their leaves. Some have huge and dramatic leaves while others are just showy and outsized enough to work well when viewed up close or at ground level. Some plants look tropical and others are right at home in the redwood understory. Some require regular water while others are able to withstand some drought. There?s a bold, breathtaking plant for every garden.

Because they reflect light, glossy leaves look even larger than they are. Make those leaves variegated or wavy with a dimpled texture and the effect is even more striking.

Here are a few large-leafed plants that work well in our area.

In partial shade try Fatsia japonica also called Japanese aralia. It?s deer resistant with bold foliage thatfastia-japonica looks tropical but still at home in the forest. Philodendron selloum with its huge, glossy leaves is also easy to grow. Oakleaf hydrangeas have it all: bold foliage that turns red in fall as well as huge white flower clusters in summer.

Tasmanian tree ferns are hardier in our winters than the Australian variety and are about as dramatic a plant as you will find. Bear?s Breech require only moderate water and serve well as a focal point in the garden.

hosta_Sum_and_SubstanceIn my own garden, I?m finding the chartreuse leaves of Hosta ?Sum and Substance? can take more sun than I originally thought. The deer walk right by their thick, dimpled leaves which is a definite plus. I like all hostas for their bold leaves whether variegated, glossy or wavy.

At ground level, some of my favorite large-leafed perennials that require only moderate water include hellebore, aspidistra, bergenia, coral bells and the dry-shade California native. wild ginger or asarum caudatum.

If you garden in more sun you can add pizzaz to your garden by planting something with large-leaves inasarum_caudatum front of those tall ceanothus, manzanita and toyon. Matilija poppy is a show stopper if you have room for it. Rhubarb, windmill palm, smoke bush and Western redbud also have huge leaves as do canna lily, banana, sago palm, loquat and angel?s trumpet. These are just a few of the many plants with big leaves that work magic in gardens around here.

Adding plants with dramatic foliage instantly makes-over the garden.
