The attached tree and plant listing has been assembled with
selections that have a proven record to survive Discovery Bay’s
difficult soil conditions. Many thanks to the Discovery Bay
Garden Club for their input and additions!
The information is intended as a tool for local residents, and
should not replace the advice or information from your own garden
or landscape professional. A plant’s inclusion on this list does
not guarantee its survival in your particular site; nor does the
absence of a particular plant mean that it won’t. If you are
still uncertain, it is recommended that a soils analysis be
performed and amendment recommendations received in each planting
Further research and care will need to be used in order to
determine the best selections for your yard. General information
is included, but residents should determine light and water
requirements, as well as any other special considerations to each
tree, shrub or plant chosen.
In general, most areas tested in Discovery Bay have high pH,
high salinity and high levels of boron that are toxic to
most plants. Because of these naturally occurring elements in our
water, it can be difficult to manage these issues. Choosing plant
material which will survive one or all of these conditions
becomes very important in ensuring the overall aesthetic and
health of your landscape. The University of California,
Agriculture and Natural Resources, publishes a book titled,
Abiotic Disorders of Landscape Plants, which has a large
section dedicated to explaining and listing the tolerance levels
of many plants and trees to all of the conditions listed above.
It is an excellent resource and a great way to start to
understand some of the complex, and often frustrating, situations
we face in our landscape.
This link can help get you started with some tips and ideas
about watering your existing or new landscape. Irrigation is an
important part of your plants’ health, and in many cases, it is
not realized that overwatering can be just as detrimental as
under watering. Taking the time to learn watering techniques and
adjustments that will provide the most efficient coverage, will
go far in benefiting your yards appearance.
