About Bamboo

Adorning the perimeter of many commercial buildings, the willowy Bamboo stands, in containers and planter beds, providing screens and landscape focal points. Its reputation as a renewable resource for flooring to furniture and even fabric, make it emblematic of the sustainability movement.

We maintain several sites in San Francisco with Bamboo plants and we appreciate their beauty, first-hand. They are finicky though, and need to be planted in just the right micro-climate. 

Because of its heightened interest we thought you might be interested to know more about them. Each Bamboo will have slightly different characteristics so in the interest of brevity we are providing general tips that apply to most Bamboo plants.

Types of Bamboo

There are numerous varieties of Bamboo.  One clarification – Lucky Bamboo is actually not a Bamboo.  It comes from the Dracaena family. 

Bamboo grows by spreading horizontally through “rhizomes”.  Rhizomes are modified stems running underground horizontally.  They represent a part of plant production and also store nutrients.

Below to the right is a simple illustration that points out the main parts of a Bamboo plant: the Culm and Rhizome.

 

Clumping Bamboo

One of the challenges of Bamboo is that it can be invasive.  The benefit of Clumping Bamboo is that its rhizomes do not spread so rapidly.  They are also slightly more drought tolerant.

  

The Parts of a Bamboo

Running Bamboo

They have long Rhizomes which enable them to spread rapidly. This type of Bamboo is considered invasive.

   

The Best Environment for Most Bamboo

  • Full sun. That means 5 hours of sun.
  • Well draining soil is preferred. Amend clay soils to improve drainage.
  • Water once or twice a week for a young Bamboo.
  • After that time once per week or less should be sufficient
  • Bamboo does not tolerate soil that is too saturated.  Roots that sit in water can rot.

 

 

Well Drained Soil

What Stresses a Bamboo?

  • Abundant sun combined with dry wind can stunt the growth of a Bamboo and cause winter burn.
  • Frost can also damage a Bamboo
  • Over-watered Bamboos can be excess yellowing foliage, rotting new canes
  • Too much sun and heat
  • Lack of water their leaves will curl in a “v” shape
 

Stressed Bamboo

Planting Bamboo in Containers

The larger container the better.  One source suggests 18”x18” and 18” deep box is the smallest size container they recommend.  Your container should be wider than it is tall.

Potting soil dries out more quickly and it needs to be moist (not wet).  Make sure your container has drainage so the plant is not sitting in water.

 

About Bamboo Maintenance

  • Bamboo is dormant in the winter.
  • Best time to fertilize is spring and summer.
  • They need occasional pruning and thinning.
  • Once any part of a Bamboo is cut, it will not grow back.
  • Bamboo leaf litter is actually good for the soil. Although in urban environments it may make the base of the plant look messy.
  • Because of how the Bamboo grows it will usually have a mixture of new and dying or dead leaves.  This can be frustrating for their owners. Some varieties can shed as much 30% of their leaves at a time.
 

51% of California No Longer in a Drought

This confirms what we expected after a ferocious rainy season that wreaked havoc throughout much the state. 

Key facts:

  • Just one year ago only 5% of the state was drought free
  • Sierra snowpack stands at 179% of its historic average (the biggest in 22 years)
  • San Joaquin Valley and most of Southern California remains in a “moderate drought”.
  • Much of Santa Barbara and Ventura county areas is in severe drought or extreme drought. Although that statistic is down from 2016.

Felicia Marcus, Chair of the State Water Board has expressed relief that water conditions have improved so dramatically, but state policy makers remain cautious.  They voted to continue with mild drought rules and re-evaluate in May.  We will know more about any irrigation regulations by that time.  And, water conservation will likely to be an important issue.

At this time:

Water agencies are still required to report use each month

Wasteful practices such as hosing off pavements and use of hoses without nozzles remain banned.

5 Landscape Trends for 2017

, , , , , , , , , , , , ,

What’s new in landscape and gardening?

Every year there are numerous reports on the latest trends in plants, hardscape, irrigation and even color. From technology to outdoor living. Designers, Landscape Architects and Green Industry pundits weigh in on what’s hot. 

There are several sources for this article. The people at Gardeners’ Guild have chimed in on the latest wrinkle. I’ve combed through Garden Design Magazine, NALP (National Association for Landscape Professionals), ASLA (American Society of Landscape Architects) and irrigation experts. 

According to some experts, Millennials are driving some of these trends.  See below.

More Local Sourcing

Using native plants is a trend that has been building over the years. Some landscape designers see the market’s interest in natives morphing to endemic plants – those which are native to a particular ecosystem.

One example – is a project we completed for U.C. Berkeley in 2016.  It was the restoration of Strawberry Creek.  The specifications required locally sourced plants and mulch. They had to be native plants grown in the Strawberry Canyon area, the location of the project.

Note: I encourage you to visit Strawberry Canyon. It is a marvel – a quiet oasis of nature sandwiched between a highly caffeinated college campus.

More building materials are being sourced locally. A reason for the increased popularity of local sourcing can be traced to climate change. Its geographic impacts and the ensuing regulation on say, the use of chemicals, water and the like are, in part, driving the preference of locally sourcing.

The reasons are practical. Reduced use of fossil fuel to transport them.

Natural Products – With One Exception

There is a gradual shift away from the use of concrete toward natural and materials. Wood, brick, slate, gravel, pea stone and natural stone are popular. Increasingly, green materials are being used for retaining walls, fencing, decking, walkways and outdoor kitchens.
ASLA says “Nature will continue to play an important role in landscape architecture and we as practitioners will continue to be inspired and create designs that emulate and mimic(bio-mimicry) nature. An increasing trend will be to use the messiness and ephemerality of nature in a structured manner to create beautiful landscapes.”

The exception – there is a trend toward the use of artificial turf. Technology continues to innovate a product that looks and feels more like grass. Could they also invent the smell of fresh mowed grass?

 

 
 

Urban Gardening

One type of urban gardening trend that Gardeners’ Guild has noticed is the increased support for urban projects that provide affordable housing, gardens providing food for local residents and restoration projects in low-income urban areas.

ASLA says (American Society of Landscape Architects) “As densities increase in cities we will see larger scale projects that will attempt to service the needs of increasing populations (housing, transport, social, green space, job creation) at a local level.”

San Francisco has a number of projects designed to improve public space. Among them is the Green Benefits District. A quote from their mission statement: “to clean, maintain, enhance, and expand open spaces, parks, plazas, parklets, gardens, sidewalk greening and the Public Realm in general in the Dogpatch and Northwest Potrero Hill neighborhoods”. There are a host of other projects aimed at revitalizing blighted areas such as the Tenderloin.  Gardeners’ Guild did some projects for the Green Benefits District.

Urban Tilth, Richmond is another example. It’s an ambitious non-profit dedicated to improving the health of its community. Their website says: “We farm, feed, forage, teach, train, build community, employ, and give back. We help our community grow our own food;” As part of 2015 Earth Day, GGI helped Urban Tilth plant a  vegetable garden at Verde Elementary School, Richmond.

Container gardening is exploding.  Urban dwellers with limited space see the low maintenance advantages of container plantings. A recent study by Harris Poll found that millennials are embracing edible gardening. Of the 6 million new people who took up gardening, 5 million of them were millennials. Their home gardening interests gravitate toward microgreens, medicinal herbs and herbs they can use in cooking.


 

Interior Plant Trends

Garden Design Magazine forecasts a renewed interest in interior plants for 2017. They say, “Just as bell bottoms are reappearing on runways, a 1970s-style fascination with houseplants is back. Millennials could have something to do with this.

Living walls for commercial buildings remains popular. They come in all sizes including a plethora modular units that can be installed like wall art. A heightened interest in plants for the office may have to do with the needs of younger workers for a healthier work environment. The extensive research about interior plants’ benefits such as air filtering as well as productivity enhancement is now widely available and posted. Plants both in the home and office is a trend that will continue to proliferate.

Irrigation

Brian O’Hara our Irrigation Manager, has noticed an uptick in the choices of add-on technology or upgrade kits that can convert a conventional controller into a “smart” controller*. This is a budget friendly option.

Smart controller technology continues to evolve. With more sophisticated cellular communication and the cloud all the onsite data can be shared with the operator. It has become a two-way wireless communications giving operators the ability to control an unlimited number of stations and flow sensors from a central remote location.

Moreover, they can be programmed and monitored by smart phone. Some include flow sensors that will text a contractor if they detect a leak in the system.

*About Smart controllers: They use weather and on-site local data sensing tools to optimize your water use.

 

 

It’s Time to Turn Off Your Irrigation

San Francisco Bay Area – The California Department of Water Resources reminds us that it’s time to turn off your irrigation!

The rains we have had and forecasts for more are sufficient in the short term. Remember that trees, shrubs and flowers use less water in the winter.  One inch of rain is enough moisture to eliminate the need for irrigation in your landscape for at least a few weeks.

On the other hand, we don’t know for sure what the weather gods have in store much beyond this week’s forecasted drenching. Keep an eye out for your plants and water if you notice them looking drought stressed.

Check out the Department of Water Resources for more information.

 

We Are Still in a Drought

Gardeners’ Guild is obsessed with weather.  Well – we are a landscape contracting company and we must adapt on a moment’s notice to rain, high winds and unseasonable heat or frost.  We also stay on top of long term forecasting because our clients depend on us to help them manage their resources.

I personally am obsessed with it. One, I need to since our San Francisco Bay Area readers are.  And two, I find it fascinating. 

Our recent heavy rain seems to suggest a wet winter.  Yes! More is predicted this weekend.  Will our reservoirs be full by next spring?  An article in the San Jose Mercury News and the most recent post on weatherwest.com has some indications based on weather forecast modeling.

We are still officially in a drought, however.  If you look at the map above you can see why.

However, there are parts of the Bay Area that have been downgraded to just “abnormally dry”.  These counties are Sonoma, Marin, San Francisco, San Mateo and Santa Cruz, Western Napa and Western Santa Clara. Unfortunately, Santa Clara County, as well as Contra Costa, Alameda, Solano, San Benito and Monterey remain officially in a drought. 

Water experts say that it would take a “very wet winter – all across the state – or perhaps two wet years – to end the drought statewide.

Forecasting from weatherwest.com post on October 25th described conflicting information that obscures any long term rainy season forecast. In his article, Daniel Swain says that climate modeling suggests a few possibilities:

  • Another Pacific high pressure ridge again
  • A warm winter
  • A possibility that Northern California’s will enjoy more precipitation than Southern California

Swain, in his last post, suggested that a La Niña was less likely. But his October article says we are “edging back to a La Niña-like” event. His evidence is cool water in the eastern Pacific and a warming trend for the tropical West Pacific.  This, he says is linked to an unusually high pressure system.

I wish could pass on better news.  And, of course we don’t know for sure.  That’s kind of frustrating. So continue rain dances, visualizing and we will continue offering advice on water conservation and irrigation that saves water.

The California drought map shown above represents the state as of November 10th. (2016). 

Some additional facts about the rain in October:
The October drenching was the wettest since 1921
San Francisco ‘s rainfall was 209% of average
But, the soil was dry and therefore the rain did not increase water levels as much as you would think.
