The Sloughs of Watsonville

sambucus_nigra_berriesEach year I wait for them in my garden and so do the robins, varied thrush, jays, spotted towhees, grosbeaks and band-tailed pigeons. The fruit of sambucus mexicana, a California native plant, is relished by an incredible number of songbirds.  The creamy flower clusters in the spring are a favorite of bees and other beneficial insects. My Western Elderberry grows tall and gangly in the shade of a California bay tree, shorter and more compact in the sun. Their exuberance for life makes me happy just to watch them provide for so many other species.

We've all driven down Hwy 1 past the strawberry fields and seen the wetlands at high tide as their many fingers reach far up into the Watsonville area. At low tide the Harkins Slough is visible off to the west, grasses blowing gently in the wind. Struve Slough passes under Hwy 1 also but most of it is hidden. The Watsonville sloughs wind around farms, fields and low hills not visible from the highway.

California has lost over 90 percent of its wetlands and the Watsonville Sloughs are one of the largest remaining freshwater marshlands in the state's coastal zone. It provides a crucial resting place for many specie of migrating birds. This area covers about 800 acres adjacent to the city of Watsonville. The slough system has 6 interlinked freshwater sloughs fed by the waters of the Pajaro Valley watershed.

Many of the plants native to the wetlands will be available at a sale to fund educational programs put on by the organization Watsonville Wetlands Watch who's mission is to protect and restore the wetlands while educating the community.

The Native Plant and Backyard Festival will take place Saturday, September 28th from 10-2pm at the Fitzeriogonum_rubescens Wetlands Educational Resource Center building behind Pajaro Valley High School. It will be their second annual plant sale. Plants beneficial for backyard habitat gardens will be featured many which were grown in their own greenhouses. Natives like buckwheat or eriogonum as they are called are a mainstay of the slough ecosystem as well as our chaparral areas and several varieties will be offered for sale.

One of my favorite eriogonums is the Red Buckwheat for several reasons. In addition to attracting beneficial insects the flowers can be dried and used in arrangements. The roots are deep and will hold the soil and bring up subsoil nutrients to the surface. They are very drought tolerant. In the weeks to come the buckwheat's long nodding flower heads will produce a huge bounty of seed favored by migrating songbirds and water birds, some of which will spend the winter here.

Coast asters will also be available for sale and make a nice addition to any garden. They provide flower color in the fall and combine well with other perennials and grasses such as yarrow and Idaho fescue. They colonize easily and help stabilize slopes and banks and can also be used as an understory plant. They are very drought aster_chilensis2tolerant. Native grasses will also be for sale as well as plants of the coastal prairie and wildflowers.

Besides the native plant sale,  Watsonville Wetlands Watch will have workshops with expert speakers, an Eco Kid Zone, food, a marimba band, a raffle, live animals and local wildlife displays. Free habitat consultations for your own backyard, demonstration habitats, a wetlands wildlife photography exhibit and a tour or their new greenhouse.

Your own backyard can make a difference for wildlife. Even a small plot of plants rich in nectar and pollen along with some water, rocks, stones and mulch can make your backyard come alive. Create your own backyard habitat by choosing the right native plants to attract butterflies, birds and other fauna and at the same time conserve water and help maintain the diversity of our animal population.
 

What to do in the Garden in September

I never want summer to end. Who doesn't love those long days and warm nights? The calendar might say fall is near but Indian summer is one of the our best seasons so I love this time of year, too. But then I get all excited when spring rolls around and everything is in bloom. It's all good. I have a check list of some garden tasks  I need to do at this time of year so I better get to them between hiking and trips to the beach.

Fertilize shrubs lightly one last time if you haven't already done so last month. All shrubs, especially broad-leaved evergrimperata_cylindrica_rubrum2eens 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 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. You can always cut lower on the stem if you need to control height.

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, echinacea and lantana. Santa Barbara daisies will bloom late into winter if cut back now.

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. If you want to start libertiaperennial flowers from seeds this is the time so that they'll  be mature enough to bloom next year.

Now through October, divide summer blooming perennials like agapanthus, coreopsis, daylilies and penstemons 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.  If you're on  a roll out in the garden, though, go for it now.

It's still a little hot to plant cool season veggies starts in the ground. They appreciate conditions later in September when the soil is still warm but temps have cooled. It is OK to plant seeds of beets, carrots, spinach, arugula, mustard, leeks, onions, peas, radishes and turnips.

If you aren't going to grow vegetables in the garden this fall consider planting a cover crop like crimson clover after you've harvested your summer vegetables.  Next month I'll talk about how to go about doing this and how this benefits your soil.

Cut back berries vines that have produced fruit.  Canes of the current season should be trained in their place.

OLYMPUS DIGITAL CAMERASpider 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. 

Now that you've taken care of your chores reward yourself by  to your garden for color in late summer through fall. Take a look at the garden areas that aren't working for you and replant. Good choices include aster, chrysanthemum, coreopsis, and gaillardia. Abutilon also called Flowering Maple come in so many colors that you probably need another one in your garden.  Petite Pink gaura looks fabulous planted near the burgundy foliage of a loropetalum. Don't overlook the color of other foliage plants like Orange Libertia and Japanese bloodgrass in the garden.

One last to do:  Make a journal entry celebrating the best things about your garden this year. 
 

Beneficial Gardens in a Small Space

waterfall_2He told me that his was a one-of-a-kind garden, unique in such a small space and would I be interested in visiting some time? I love being invited to tour all types of gardens but I had an inkling that the garden of Rich Merrill, former Director of the Horticulture Dept. and Professor Emeritus at Cabrillo College, would be something special.

It was a beautiful morning when I arrived at Merrill's garden overflowing with flowering plants, small trees, edibles and water features. Many large boulders, surrounded by pebbles, caught my attention in such a small space. All part of the design to attract beneficial insects I was told. His organic garden is teeming with small beetles, spiders, predatory bugs, syrphid flies, parasitic wasps and lacewings. It's the ideal method of pest control, environmentally safe and free of cost.

While admiring his lovely garden, Merrill shared his knowledge of beneficials- from insects to birds to spiders to frogs and beetles. They are all part of the ecology of a successful habitat garden. I could barely keep up, writing down notes on my yellow legal pad as he weaved a story about how each of the elements in his garden contributes to its total health. I was never able to take one of his classes at Cabrillo College so this was a real treat. My own private class.

The wide diversity of plants in Merrill's garden provide moisture, shelter, prey and nutrition in the form of santivalia2nectar for carbohydrates and pollen for protein. His plants are "beneficial" plants because they foster beneficial insects. It just so happens  that many of these plants are also beautiful in the garden. Some of his favorites include composite flowers like sunflowers, marigolds buckwheat, scabiosa and santivalia or creeping zinnia.  They have flat  flower clusters with accessible landing platforms and small nectar and pollen to make it easier for insects to feed. They in turn eat the tiny eggs of the bad bugs in your garden. His is a complete ecosystem.

This 800 square foot garden happens to be in a mobile home park but any small space could be designed to be as beautiful and full of life as Merrill's. Most of my clients ask for a garden filled with color, hummingbirds, songbirds, butterflies and wildlife so I came away with lots of great ideas.

blue_thunbergia2Once a teacher, always a teacher. Merrill gave me a handout he'd prepared for Renee Shepherd of Renee's Garden, explaining in more detail why he lets the broccoli go to flower to attract beneficials and why he allows aphids on his cruciferous vegetables to feed the beneficial insects when prey is scarce so they are on hand should he have an outbreak of bad insects that might ruin his flowers and plants.

As we strolled within a border of palms, olive trees, phormium, bottlebrush, Marjorie Channon pittosporum and cordyline, Merrill showed me his philosophy of right plant in the right place in action. Asclepias curassavica, commonly called Mexican Butterfly Weed, has self sown on its own in unexpected spots. One happened to come up next to the gorgeous blue thunbergia by the pondless waterfall making an awesome combination. Both monarch butterflies and hummingbirds enjoy the nectar.

Next to a red salvia, a red and white bicolor Rose of Sharon made it's home. Merrill lets all his plants intertwine and the pink flowering Heckrottii honeysuckle was already inching up into an olive tree. Other salvias in his garden include Hot Lips, San Antonio and San Jacinto. There isn't room to grow any of the larger salvias, Merrill explained. He swears he doesn't know where the brilliant blue one came from. Must be from the "fairy dust" his wife, Dida says he sprinkled over the garden to make everything grow so lush.

She loves flowers for fragrance and cutting so in several beds they grow gardenia, lemons, roses and alstroemeria among the alyssum which is a prime syrphid fly attractor. Several bird of paradise, obtained from different locales in the hopes one will be hardier grow beneath a tall palm.

Merrill grows only the vegetables that do well and are the most nutritious like kale, onions, garlic, broccoli and collards. He enjoyed growing cucumbers this year and has a large pumpkin in the making for his grandson. The rest he gets from the farmer's market. He had developed his own strain of elephant garlic which is actually a leek and has a milder flavor than garlic. I left his garden with a gift of elephant garlic and lots of inspiration.
