Terra Sole Nursery Trials New Plants

Leave a comment

Have you ever wondered what it would be like to start your own little nursery on your property? What would you grow? How would you decide?  Over the years, I've been asked by home owners with a bit of extra property what would be good to grow. What is there a market for? So I decided to ask some friends who trial plants on their Watsonville property and operate a small nursery there how it all works.

Terra Sole Nurseries was founded in 2004 by John and Sherry Hall with the goal of experimenting and growing native, unusual and drought tolerant plants that are adapted to our dry summer climate. "We push the limits on water use in our test garden until we fall too much in love with a plant and can't bear to see it die with our tough love approach", Sherry said as we talked about the their operation.

Just back from attending the California Spring Trials,  Sherry and John were excited to share how they decide what to grow In their nursery. Their focus is to grow a large variety of native and unusual plants, some of which are old-fashioned, some are hot new introductions. What treasures did they find this year?

During the course of a week at the Spring Trials,  the world's prominent plant breeders, propagation specialists, growers, marketing professionals and plant enthusiasts share the latest and greatest at several open houses throughout California. The robust plant varieties of today are a direct result of the countless hours and decades of study from the dedicated professionals spending their time observing, testing and experimenting the new varieties that are more disease resistant, more floriferous, the best performers and are easy to grow in ordinary landscapes and gardens.  

How does a plant get from an idea in a breeder's mind to your local nursery? It all starts with the breeders who might cross pollinate thousands of plants to select maybe a hundred of the best ones. Then the growers buy an unrooted cutting or the seed or plugs of rooted plants and grow them onto a larger size. This is where the finish growers buy the plugs and liners to put into bigger pots growing them to retail or sellable size. Terra Sole Nurseries bought some of the newest plants on the market this year themselves.

What are some of the newest trends that we might see in our neighborhood nursery this year? The breeders of impatiens have developed a variety that appears to have a gingerbread man in the center. Called Patchwork this  impatien has a bigger flower and comes in six bi-colors.

Grafted vegetables, higher in antioxidants, are being developed. Non GMO vegetable varieties are grafted onto vigorous rootstalks to produce a plant disease resistant higher in nutrients. Tomatoes, basil, cucumbers. peppers and lettuce are just some of the vegetables being grown.

Biodegradable pots made from wheat are another of the new trends being offered for sale at the Spring Trials. The pots look like plastic yet breakdown after being used and can be recycled in your compost system. They hold up to the normal environmental pressures of heat, water and cold.

Sunset Western Gardening and HGTV are both offering their own branded plants that are available this year. Patented varieties coming out include a compact hardenbergia called Meena, two upright. compact nandinas- Flirt and Obsessive with bright red winter color and a compact mahonia called Soft Caress with non-prickly foliage. A cold hardy salvia named Amistad that has a very long bloom time will also be coming out soon.

To simplify choices for gardeners, better dahlias, calibrachoa, petunias and pansies are coming on the market this season. Several types are grown in the same pot so the buyer need only to plant one of these in a basket or container to get a combination that will look good and grow happily all season.

With so many plant choices which ones do Terra Sole Nurseries trial in their own garden and grow in their nursery? Next week I'll talk about what Sherry and John have their eye on, which plants they grow and the results of their own plant trials. You can find out more about the nursery at www.terrasolenurseries.com.

San Francisco Flower & Garden Show 2012

Leave a comment

Every year after attending the San Francisco Flower & Garden Show I'm exhilarated by the creativity of the display gardens  and the fresh use of familiar plants. Don't even get me started on the new plant introductions I want to use in my next landscape design. This year the world-class show celebrated its 25th anniversary.

A Flower and Garden Show is a huge and complex production. Creating the 20 display gardens is a demanding task and planning for them begins many months before the show opens. By the night before the show opens 1,200 cubic yards of sawdust and mulch ( that's about 150 dump truck loads ) have been spread and 280,000 pounds of rock stacked in undulating walls and water features.

The flowers and plants for the garden come from all up and down the West Coast. Many plants are forced into early bloom for the show as Mother Nature doesn't always cooperate. Even flowering trees are sometimes kept in greenhouses so that their buds can be timed to open the week of the show. It's not a perfect science. One display garden creator who garnered 5 awards told me that hundreds of daffodils she had planned to use in her garden bloomed a week early due to warm weather. 

This year the theme of the show was "Gardens for a Green Earth". There were tips for edible gardening at home including containers for herbs and veggies on the patio and small space gardening, too. One of my favorite gardens combined tomato and flowering vines cascading over the edge of a stone vaneer wall.  Raised vegetable boxes bordered the deck for easy access and a stone water fall splashed into a huge half oak barrel.

Another interesting garden was the Low Impact Bay Friendly Garden. Modern in design, this low water-use garden featured tall raised beds surrounding a pervious concrete stepping stone patio set in a gravel base. Pervious concrete is said to be able to take in storm water a a rapid rate of over 5 gallons per minute per square foot of surface area. That far exceeds the flow rate needed to prevent runoff in even the most severe rain events.
The rainwater is temporarily stored in the course gravel layer underneath while it is allowed to naturally percolate into the underlying soil. This could be a good solution to solve site drainage problems.

Most of the display gardens featured water in them. Some were large affairs with cascading boulders while others were small and understated. In one, a length of copper tubing delivered a shower of drops in front of an aged corrugated iron panel. Another consisted of a simple stacked flagstone ledger waterfall flowing into a flagstone pond- a DIY project?  Even used tires were used as the base for the flagstone edging around a pond although frankly, I couldn't picture this water feature in anybody's backyard. One I did like was a simple flume of water pouring into a small metal rectangle lined with Mexican black pebbles. A little feature with lots of impact.

Fire pits were prevalent, too. From ornate fireplaces to glass filled affairs to simple metal rounds filled with cobbles outdoor living is enhanced with fire and water.

I had to laugh when a man asked me at one of the gardens what I was taking a picture of.  Well, I explained, I take photos of paths and steps and how they're put together and the materials they're made of for future reference. "Oh, that's a good idea" he said, and started taking pictures, too. All in a day at the San Francisco Flower and Garden Show.

March Gardening Tips

Leave a comment

The rain last week was welcomed by all of us who like to watch things grow. There's a patch of grass growing beside a creek where I live that is the brightest neon green I've ever seen. Whether you call it apple green or lime green or chartreuse it shouts spring officially started on March 20th, the vernal equinox.

Spring weather here in the Santa Cruz Mountains can be warm and sunny one day, gray and rainy the next. Strong winds often blow last years crop of oak leaves all over the deck you've just swept but none of us would  live anywhere else.

Now that daylight savings time has started we have more time to spend out in the garden. One simple addition that makes being outside in the cooler evenings more enjoyable is a fire pit. For ideas search Google images to be inspired. You can install a simple metal fire pit for burning wood or get fancy with a stone pit surrounded with gravel and stone seat walls. I guarantee you'll be happy you set aside a space for this addition to your garden.

What other to-do's are there in the garden in March?

Fertilize – Take advantage of the moist soil to fertilize your garden.  Lawns and groundcovers are beginning their spring growth spurt and new leaves on trees, shrubs and perennials are starting to emerge. Spread compost, manure, or organic fertilizer to help plants get off to a strong start. Your citrus may be looking yellow from lack of nitrogen which has leached out of the soil through the rainy season and they may be lacking in iron.  Feed them with citrus and fruit tree fertilizer. I like to put out a granular or time release fetilizer before a storm and let the rains water it in for me.  Make sure you keep fertilizer off the foliage and crown of the plants. Wait to feed azaleas, camellias and rhododendrons until after they bloom.

Prune – Clean up winter damage on perennials, vines and shrubs.

Transplant –  If you need to move any plants in the garden, now is a good time.  Plants are full of growth hormones and recover quickly from transplant shock.

Divide perennials –  To increase your plantings, lift and divide black-eyed Susan, gaillardia, catmint, coreopsis, daylily, diascia, geranium, ground morning glory, lamb's ears, penstemon, shasta daisy, society garlic and yarrow.  Also I see my hostas are just beginning to come up so dividing them or transplanting them at this time is easy and you don't risk ruining their georgous leaves later after they unfurl.

Weed – Pull weeds regularly before they set seed. They pull out easily from moist soil. Think of weeding as free gym time.

Houseplants – Now that the days are getting longer and temperatures are inching up your houseplants can be repotted if roots are poking out of the bottom or are matted on the surface.  Houseplants rest in the winter and don't require much fertilizing.  You can resume feeding now with a balanced fertilizer. Your plants will benefit also from leaching the accumulated salts from the soil. Take them to the sink and run room temperature water through them several times.  Houseplants clean the air.

Our last estimated hard frost of the season is approximately March 15th. Sometimes we get light frosts into April so have frost blankets or any blanket or towel ready to protect seedlings. Even a cardboard box over frost tender new growth will work fine.
