Newsletter 2 February 2017

This is the second newsletter since Summer-Dry was launched two years ago, so those of you who might have been looking for this update expecting news have not missed anything directly, though there have been about 40 plant descriptions posted to the blog.

The initial phase of the site has been a success in simply luring Nora Harlow to write the plant descriptions and getting Dave Fujino of California Center for Urban Horticulture to help us apply for a grant to upgrade the WUCOLS database.

That grant application to California Department of Water Resources (DWR) seeks to add photos and plant descriptions to all of the low and very low water use plants in the WUCOLS database.  Those plants would then be added to Summer-Dry, greatly expanding the initial database created for the East Bay Municipal Utility District (EBMUD) and all photos become accessible per the terms of any State of California grant.

Is the drought in California over ?

That is the subject of the most recent blog post and  it depends on where you look, but we will always need to garden with water conservation in mind.  The recent post has some excellent links to official drought monitoring sites and links to other news sources.

Going forward, Summer-Dry will be sending out a monthly newsletter, a digest of blog posts, news, and plant descriptions. We now have a mail service that allows this to happen automatically for subscribers.  Sign up at the bottom of the Home Page.

Now that we have a newsletter service look for us to have more information to share, “Like” our Facebook page, and spread the word that gardening is alive and sustainable in summer-dry climates.




Is The Drought Over ?

It has been raining like crazy in California this winter.  Or rather, it has ben raining like a normal winter. In a summer-dry climate we expect it to be winter wet.

But is the California drought over ? Here is a map showing the overall change in exactly one year, since February 2, 2016.

While it has been a dramatic change it its not over; Southern California is still below average.  Although there is above average snowpack in the mountains, which will insure adequate water, the State is still experiencing water supply shortfalls and five years of drought have left California with a significant water supply deficit, especially when it comes to groundwater basins.

Who decides when the drought is officially over ?  The State Water Resources Control Board will vote on Feb. 8 whether or not to officially extend drought regulations. Item 9.

To follow the progress of the drought and the many water conservation resources that various government agencies provide, we have listed the most active Resources and summarized them below, including a few timely rainfall reporting sites:

California Water Year Totals from National Oceanic Atmospheric Administration NOAA

California DWR Daily Reporting Stations – Department of Water Resources

Two great websites with up to date news:

Water Deeply In-depth coverage of the California drought.

California Water Blog –  UC Davis Center for Watershed Science

Government resources:

Drought Portal California official website

California Water Science from US Geologic Survey and specifically CA Drought

Save Our Water State of California Water Conservation tips and action

Newsletter 1 January 2015

433-335It’s a New Year, the first year of the Summer-Dry Project.  In California we are happy to report we had heavy rains in early December but a bit nervous that it has not rained in 3 weeks.

So it is with the Project, launched with much excitement last year but awaiting fresh energy to expand the database to include garden photos all nursery plants available in California according to the WUCOLS.

Soon we hope to have Nora Harlow, the Project Director and author of the EBMUD book, Plants and Landscapes for Summer-Dry Climates as our resident expert who will add posts and information on plants in the database.

We will be reaching out to various water agencies and the California Department of Water Resources for help and funding of our project.  No matter how much rain we may get this winter, or any winter, we garden in summer-dry conditions and must educate gardeners on the best plants for sustainable practices.

We believe photos can help encourage best practices if gardeners can see real gardens, beautiful gardens.


The Summer-Dry Garden


holt_782-158.tifSummer-dry gardens can be beautiful.  The art and science of gardening is learning which plant prosper in garden settings. Many plants are meant for summer-dry climates and don’t need lots of water, though careful irrigation improves their beauty.

I do water my own California garden in summer; and so does every farm and every garden – all summer.  It simply doesn’t rain.  The irrigation water has to come from somewhere, other than a faucet. Continue reading

Drought Tolerant is Irrelevant


holt_389-863.tifAll plants are drought tolerant in their native habitat and no plant can live without water.

No matter where a garden is located, the tropics or the desert, the plants in that garden should naturally tolerate periods of lower than average water.  They may thrive with supplemental water during dry periods but the term “drought tolerant” can be very misleading, especially in summer-dry climates.

A Summer-Dry Aesthetic


holt_782-190.tifWe want to change the aesthetic of what we expect to see in a garden photo in summer-dry climates.  Beautiful photos of beautiful gardens inspire gardeners to mimic what they see.

Many photos in garden books and magazines are from East Coast and English style gardens, that, while are certainly lovely in those settings, are wrong in more arid and summer-dry climates.  Water is especially precious in summer-dry climates, lush images from other climates mislead gardeners to try inappropriate and unsustainable gardens.


We want to inspire gardeners to choose plants that are water wise and garden styles that fit into the habitats and natural beauty nature provides. So here at Summer-Dry we celebrate plants that naturally thrive with less irrigation in the summer and receive most of their water as rain in wet winters.

We don’t like the term drought tolerant since all plants are tolerant of drought in their native habitat and no plant can survive without some water. The art and pleasure of gardening is using the right plant in the right place.
