Succulents for Color

Fresh from a day spent among the spectacular world of succulents I’m excited about using these unique plants in new ways. Succulent Gardens in Moss Landing hosted a day of speakers, tours and demonstrations showcasing these  fabulous, unearthly-looking plants. I’ve always liked succulents grown along a walkway, around accent boulders or tucked between perennials. Now I’m creating awesome vignettes in containers that I can move under an overhang to protect from excess rainfall and frost if necessary. There are so many impressive varieties to choose from. Here are some of my favorites that I enjoyed on the tour.

Many showy succulents need only a bit of protection during our winters.  Aeonium decorum Sunburst is one of the showiest species with spectacular variegated cream and green 10" rosettes. This plant  grows 2′ tall and looks terrific with black Voodoo aeonium in a pot. Sunburst is hardy to 28 degrees while Voodoo will go down to 32 degrees. Aeoniums do so well in our climate as they come from Arabia, East Africa and the Canary Islands where winter rainfall is the norm.

Aeoniums propagated from tissue culture are now affordable. There was a time when a 2" seedling cost upwards of $100. Tissue culture involves taking the cells from the core of the plant and growing it in a sterile medium like agar. The resulting plants are exact copies of the mother plant and mature quickly.

Echeveria grow naturally in higher elevations of central Mexico to northwestern South America and so do well in our our cool wet winters. After Glow is frost tolerant and looks to be painted with florescent paint. There are spectacular hybrids being developed every year. These are not as hardy as the traditional hens and chicks but well worth the effort to find a place where they can survive a freeze. Frilly Mauna Loa sports turquoise and burgundy foliage while echeveria Blue Curls looks like an anemone in a tide pool.

Aloes from South Africa and Arabia are old world plants. Many like the medicinal aloe vera are frost tender but some, like the tree-like aloe plicitilis, are hardy down to 25 degrees and look great either in the garden or in pots.  Did you know the Egyptians used aloe in the mummification process or that there are no known wild populations of aloe? In South Africa, an aloe called ferox is used in the same way as aloe vera for burns and stomach problems. This variety is hardy down to 20 degrees and blooms in January.

When potting succulents in containers, be sure to use a quality potting mix as good drainage is essential. There are special succulent mixes available but succulents are forgiving as long as the soil drains freely. A great tip I got from Debra Baldwin, author of Designing with Succulents and Succulent Container Gardens, is to add Dry Stall to regular potting soil. Dry Stall is a horse bedding product made with pumice. It is similar to perlite although heavier and less expensive.

Her recipe for succulent soil mix differs with the size of the leaf. For fat, juicy leaves use 75-90% pumice of perlite to potting soil. Fine-leaved varieties thrive in a soil mix of 25% pumice to 75% soil and all the rest get a mixture of 50/50. Don’t add gravel or clay shards at the bottom if planting in a container as this impedes drainage. It work best to fill the entire pot with soil, top to bottom.

Because succulents use little water they are easy to care for. If you hate the idea of having to water after you get home from work, create the garden of your dreams with succulents.

Drought Tolerant Olives

Summer has finally arrived. Took a while- a long while this year- but now we can enjoy nice weather and our beautiful gardens. The extra rainfall has allowed many trees, shrubs and perennials to grow lush and full like never before. As summer heats up think about adding drought tolerant plants especially in areas that are hard to water.

Plant an olive tree. They take the heat and are drought tolerant once established. Olives are easy to care for. They require little pruning and have few serious pests. Their grayish foliage and graceful, billowing appearance are a welcome accent to an all-green garden. The attractive gnarled branching pattern is also quite distinctive and they can live for 500 years.

For ornamental purposes or next to paving, choose a fruitless variety like are old favorites. Olives can be traced originally to southern Turkey in about 3150 BCE. The spread of the olive tree to the Mediterranean areas of Italy, France, Spain and Portugal probably coincided with the trade of wine, date palms and figs. They were introduced to California mission gardens in the 1700’s for the oil their fruit produces. Many of the missions still have the original olive trees. Underplanted with drought tolerant perennials like sedum ‘Autumn Joy’, yarrow, lamb’s ears, mimulus, Santa Barbara daisy or agastache they can be a focal point in any garden.

May is Water Awareness Month

We know that water is a precious and vital resource.  Even our bodies are about 60 % water and the brain is 70%. Less than 1% of the water on the Earth, however, is suitable for human consumption. With the population increasing and the water supply staying the same, water conservation indoors and out is important. A well planned landscape makes water conservation outside the home even easier. Since May is Water Awareness month here are some tips to consider.

Start with simple things. Rock, stone, and permeable paths and driveways add visual interest to the landscape and don’t require irrigation. Improving your property’s soil quality aids in saving water regardless of the plants grown there. Organic materials added to the soil help establish a strong root system for plants. Nutrients in the soil allow the plants to become stronger, too. Adding a layer of mulch increases the plant’s efficiency by retaining moisture and keeping the soil temperature stable.

Choose the right plants for your location. California natives or plants from similar climates in the world are low maintenance, low irrigation plants and usually need less tending, fertilizer and pruning. Your choice of groundcover can make a big difference, too, in how much water the landscape saves. Keeping grass areas to a minimum generally reduces the amount of water needed to keep the landscape looking green and fire safe.

Your method or irrigation helps conserve water. Hand watering where possible, especially new plantings, directs the water exactly where it needs to go and you can shut off the hose as soon as the plants receive enough water. A soaker hose is another efficient option that reduces evaporation during the watering process. An automatic irrigation system with a rain sensor, weather based controller or soil moisture sensors is the newest way to save water.

Both San Lorenzo Valley Water ( http://www.slvwd.com ) and Scotts Valley Water Districts ( http://www.svwd.org ) offer many tips and incentives to conserve water. Scotts Valley Water Conservation intern, Amanda Robinson, explained they are very interested in getting out the word about using less water-intensive plants – there are lists on the website of drought-tolerant plants and water smart grasses-  as well as customers replacing lawns and old pop-up sprinkler systems. Their rebate programs offers several landscaping credits including  drip irrigation conversion credit, weather-based irrigation controller credit, replacement credit for converting an existing lawn to water-wise grasses, and lawn replacement to synthetic grass. Both districts have guidelines and procedures to apply for the rebates on their websites.

Scotts Valley gave 13 lawn replacement rebates in 2010 and 5 so far this year. Weather-based irrigation controller credits numbered 5 in 2010. Cistern credits for catching and storing rainwater totaled 3 in 2010 and 1 Low volume irrigation system conversion credit was given. Visit the web site for your water supplier to get more info. Don’t miss out on this important information and possible rebate.

There is even a workshop this Saturday, May 14th at the Scotts Valley Water District office from 10am – 1pm. Sponsored by the Ecological Landscaping Ass.and presented by Joy Albright-Souza, attendees can bring dimensions of their yard or project area and take home a class-created landscape plan. The cost is $45 and can be paid by check at the door. Call 831-419-5994 for more information.

Let’s make every month Water Awareness Month.
