Develop a Mulch Master Plan

/in , /by

How much mulch does your landscaping plan need? To develop your mulch master plan and answer this question, you first need to understand the job it will perform in different areas of your watersmart landscaping plan.

  • If you want to hold in moisture and keep down weeds: Use three to six inches of mulch on top of the soil
  • If you want to maintain your planting beds: Maintain two to four inches of mulch on beds at all times

Master Tip: Keep mulch one to six inches away from plant stems. When mulch crowds them, it can cause plants to rot due to moisture.

For accurate results, check these numbers:

  • Square footage of your landscaping
  • Thickness of your mulch cover in inches

Take your square footage, multiplied by mulch thickness, and divide this number by 12. The result is the amount of mulch you need in cubic feet.

Example: 891 square feet of land, multiplied by one inch of mulch, divided by 12 = 74.25 cubic feet of mulch.

Avoid these mulch types around plants

Inorganic mulches don’t decompose to feed your soil microbes and keep your plants and garden healthy and thriving. There are also some organic mulches containing dyes or other chemicals. Others such as shredded redwood take a very long time to break down.

Master Tip – These are the types of mulches you should use only in areas without plants:

  • Shredded redwood
  • Dyed wood mulch
  • Decomposed granite
  • Gravel
  • Rubber pellets

Water Conservation Garden Growing Strong With New #FreeDayFriday Program

/in , /by

In a normal year, The Water Conservation Garden in east San Diego County provides resources and education for 88,000 children and families annually. Due to the coronavirus pandemic, meeting the Garden’s mission took a little extra effort and creativity.

To remain open after its initial closure and re-opening in June 2020, the Garden now charges a small admission fee. Thanks to the new #FreeDayFriday initiative, supported by a donation match through the Rice Family Foundation, more than $60,000 in contributions now allows the Garden to offer free admission on the second Friday of each month, starting February 12.

“We can now create #FreeDayFriday so every person in the community, no matter their ability to pay, can enjoy all the Garden has to offer,” said Jennifer Pillsbury, Water Conservation Garden executive director and CEO.

The Garden continues operations under safety modifications

The Garden’s elementary school education program featuring Ms. Smarty Plants is now available online for grades K-2 and 3-6, including full lesson plans and video. Safely distanced Family Field Trips are also available for schools, homeschool groups, and individual classes.

“Our garden, not only is it an educational site, but we have classes that coincide with how to make what you see at our garden happens, where to buy the supplies, and how to do it,” said Pam Meisner, director of operations and education and founder of the Ms. Smarty Plants program. “We are the go-to place in San Diego for sowing beauty with low water use plants.”

“We can’t survive without water. But people don’t value that. One of our reasons being here is to show them the value of water and make that part of your life,” added Meisner.

Classes on sustainability, gardening, and art are currently offered online. Professional one-on-one phone or video consultations on water harvesting, and how to set up, retrofit, and maintain your irrigation or landscape are available by reservation through the website at thegarden.org/consultations

To support the Garden through the ongoing #FreeDayFriday program, visit FreeDayFridays.org.

A task force of water agencies and municipalities conceived the Water Conservation Garden in response to six years of drought in San Diego County.

Otay Water District, Helix Water District, and Cuyamaca College kick-started the effort in 1990. By 1992, the San Diego County Water Authority, City of San Diego, and Padre Municipal Water District joined the effort, forming the original Water Conservation Authority.

The following year, the Grossmont-Cuyamaca Community College District approved the establishment of a 4.5-acre Water Conservation Garden adjacent to Cuyamaca College.

Oxygen, Water, and Life Create Healthy Landscape Soil

/in , /by

Your landscaping soil needs three things to feed the billions of microbes within it to transform brick-hard, lifeless dirt into healthy, living soil sponges: oxygen, water, and life. Think OWL to remember these important, interconnected factors.

Oxygen lets microbes breathe free

Oxygen is needed by healthy plant roots and soil organisms. Healthy soil has lots of tiny little pockets of air. When soils are eroded, graded, or disturbed, their structure becomes compacted and hard. Compaction takes place when tiny air and water bubbles are squeezed out of the soil. This kills the healthy microbes working to keep your soil replenished. Microbes can be killed by fertilizers, pesticides, or even heavy traffic from people or vehicles. 

Water for your microbes and plants

Microbes and plans both need water to live. But too much water in your soil will displace oxygen, saturating the soil. This creates an anaerobic condition. It is the unhealthy microbes like bacteria, viruses, or parasites that prefer anaerobic soil. If this condition persists, diseases may develop. They will endanger the health of your garden.

Water is constantly moving through the soil. Water in the soil needs to be replenished as plants use it, as it evaporates from the soil surface, and as gravity pulls it down past the root zone of your plants.

Bring your soil to life

The microbes consume organic matter, and then they are consumed by bigger creatures (worms, ants, slugs, centipedes, larvae, etc.). They are consumed in turn by creatures further up nature’s food chain. Photo: Malcolm Fowles, Wikipedia

Life in the soil includes all the bacteria, protozoa, nematodes, and fungi, the food they eat, the excretions they make, and the root systems they sustain. Living microbes are most quickly incorporated into your soil by adding high-quality compost.

Plants attract microbes to their roots by feeding them carbon. Bacteria and fungi hold the soil together with microscopic glues and binders. The microbes consume organic matter, and then they are consumed by bigger creatures (worms, ants, slugs, centipedes, larvae, etc.). They are consumed in turn by creatures further up nature’s food chain.

Carbon and other nutrients cycle through these many life forms, creating healthy living soil, no matter what the soil type.

Without any of these elements, your landscaping will not thrive. Organic matter, planning and some labor may be involved, but creating healthy soil using the OWL method –  Oxygen, Water and Life – will pay off in reduced maintenance, reduced inputs, reduced pollution on land and in our waterways, and the beauty of your thriving, healthy landscape.

Improve Your Landscaping Soil With a Soil Test

/in , , /by /Water News Network

One of the first steps in your landscape makeover project involves preparing the soil to allow efficient use of irrigation. San Diego County soil quality needs a lot of help. The area is defined by impermeable soils with poor infiltration areas. Water doesn’t flow through the soil to replenish the groundwater, because it is made primarily of clay which is too dense.

Improve Your Landscaping Soil With a Soil Test

One of the first steps in your landscape makeover project involves preparing the soil to allow efficient use of irrigation. San Diego County soil quality needs a lot of help. The area is defined by impermeable soils with poor infiltration areas. Water doesn’t flow through the soil to replenish the groundwater, because it is made primarily of clay which is too dense.

In impermeable soils, irrigation doesn’t soak evenly into the ground, or flow through living soil and plants in a healthy way. No matter where you do your landscaping, you need to put in some work to improve your soil structure as much as possible. Irrigation will be more efficient and more cost-effective, and your landscape plants will receive the nutrients and water they need to flourish.

Check for particle size

Before you can build better soil, you need to figure out what type of soil you are working with. The three basic types of soil are:

  • Clay: Soil made up of the smallest particles
  • Silt: Soil made up of a mixture of particle sizes
  • Sand: Soil made up of the largest particles

In general, sandy soil drains faster than clay soil, because there is more space among the larger sized particles. Soil structure also influences soil quality. Lifeless, compacted sandy soil will not absorb water, while healthy clay soil will be more sponge-like, holding and releasing water when needed.

Learn your soil type using the jar test

Some tests can be done onsite to figure out what kind of soil you have. Others require lab analysis. Certain conditions require specialized tests, such as soil used for food production or soil receiving a lot of stormwater.

For most landscaping projects, you can test your home landscaping soil yourself. Watch the video, then follow these directions for a “Jar Test.” This is a fun science project to do with kids.

  1. Use a one-quart size glass container.
  2. Add one cup of soil from the garden. You can select one area or take samples from several areas and blend them together.
  3. Add three cups of distilled water.
  4. Close the jar and shake it until all the soil solids are suspended in water.
  5. Put the jar on a shelf and wait 24 hours.
  6. If the container is still cloudy, wait another 24 hours.
  7. After 48 hours, the soil layers should be settled on the bottom.
  8. Measure the layers in proportion to each other, with the total adding up to 100 percent.
  9. Sand will be on the bottom, silt in the middle, and clay on top.

Refer to the graphic to determine your soil type, based on the proportions of sand, silt, and clay.

Robin and Mike Zeigler received the “Best in District” award and a $250 gift certificate.  It was important to Robin, Mike, and their daughter Kallie, to be water smart with their landscaping choices during a comprehensive landscape and irrigation upgrade.  After taking a WaterSmart Landscape workshop last spring, the Zeiglers used their knowledge to transform their monotone front lawn to a colorful bloom filled garden reminiscent of their favorite European gardens.

The Zeiglers’ landscape includes a wide array of drought-tolerant plants that provide year-round blooms that attract butterflies, birds, and bees.  Vibrant splashes of magenta and coral geraniums, bright yellow yarrow, and Russian blue sage line the flagstone walkway.  Clusters of white alyssum flowers contrast with the bright red and green hues of aeoniums, sedums, and kangaroo paws (Anigozanthos), delivering a beautiful backdrop for the river rock bed flowing through the yard.

Plant selection includes a variety of pollinator-friendly choices such as red sage, “Desert Blaze” Salvia gregii, “Margarita” Penstemon, “Hot Raspberry” butterfly bush, with Wild Dagga or Lion’s Tail (Leonotis leonurus) mixed in with traditional landscape favorites such as lantanas, geraniums, and star jasmine.  The Zeiglers have enjoyed their neighbors stopping to ask who did the landscaping and complimenting the transformation.  Robin Zeigler says she “couldn’t be happier” with the results and has already started on the backyard.
