The 20 Minute Garden - Introduction


I am a 20 minute Gardener and you might be too. We all have a tug of war with gardening disposition (née, addiction) at one end, and other devotions at the other end (job, kids, clubs, sports, faith activities, and all the other commitments we are disposed to servicing). 


The 20 minute garden is accomplished in three phases: 
  • 1st & 20: Plan, Checklist, Prioritize. 
  • 2nd & 20: Labor, Blaze, Do. 
  • 3rd & 20: Experience, Listen, Feel.


I am blessed with a husband willing to participate in phase 2 and 3 & 20, a contribution that is a multiplier, not simply addition. Sometimes he feels like Sisyphus in the garden. The gods had condemned Sisyphus to roll a boulder up the mountain, and every day, the boulder would roll back down. Viewed that way, gardening would be a punishment, if not for my gratitude, specific assignments & 3rd & 20, with a cold beer.



I aim to complete all three phases, every day, but even three days each week keeps the garden growing.

Thanks to inspiration from Maridan Valor, a young woman & blogger who inspired me to journal. I write mostly about gardening. It helps me to keep track of what works and doesn't work in my garden & to remember what is done or needs to be done.

Garden Scents, Cents & Sensibilities, Beyond Visual Appeal



    Much of what I admire in garden design, I learned to love from the time I was just a caterpillar. I learned that the garden looked and smelled good. We delighted in found objects and shared the bounty. I learned to tread lightly as an intruder, in a place where bees and snakes belonged as much as butterflies and ladybugs. Still, there was an ease about the garden. Additions contributed to that ease, or out they went, like a weed. Expectations raised, I felt prepared for contemporary gardening where planning produced a multi-sensory, beautiful, fragrant, vigorous and adaptable, ornamental and edible garden. Every gardener moves the practice, and we now apply interior design principles to complete the garden from ground up, with art, rooms and rugs. Gardening fulfilled makes scents, cents & sensibilities.

    Scents

    My garden wishes are filled with memories of my Grandma's nose buried in the center of childish fistful of violets, their scent forever associated with her soft, sun warmed arms. Do I remember her garden? To this day, I can still close my eyes and see the secret location of Grandma's bluebells. My love of fragrance in the garden comes with a love of native plants, the plants of my childhood memories. Later I learned that native plants are almost always more fragrant than their hybridized counterparts.

    I admire Piet Oudolf, the Dutch Master of Gardens, who, consistent with my childhood foundations, creates visually stunning gardens, planted in naturalized drifts, with graphic patterns of color and texture for all seasons. Unlike the majority of designers, Piet pays close attention to scent, drawing in pollinators and giving visitors the deeply intimate human experience of being wrapped in sweet perfume. Since we aren't likely to have Piet walk by and volunteer to paint our gardens with fragrant plants, we'll have to make "scents" of the garden on our own.

    Cents

    Our practices in the garden make or take "cents". Lawns are expensive for what little pleasure they provide & frankly, I’m limited in the amount of work I can do, so low maintenance gardening is my goal, like most. No garden is no maintenance, but lawn requires more than weekly care with fertilizer and pesticides, spread in regular intervals, all in an attempt to make the wrong plant happy in the right place. To reduce the impact and cost of chemical support, my beds have been eating the lawn for years now, with only a 10’ x 16’ amebic shape remaining.

    Making “cents” in the presence of long term drought conditions, requires a low water, environmentally sustainable garden. Native plants, with deep root systems, bread from genetic evolution concurrent with climate change, are hardier in good years and lean. Piet Oudolf relies on plants that thrive in stark or low nutrient conditions and packs them tightly to discourage weeds,  increasing survivability, reducing chemical controls and water usage, saving money, making "cents".  

    Climate may be beyond our direct control, but there are a number of factors immediately within our wheelhouse - best practices for properly planting the right plant in the right place, watering infrequently and deeply, mulching to retain moisture, sanitation of grounds and tools, reduced use of chemicals, pruning, knocking down invasives, and dividing as needed to multiply and invigorate plants. 

    Sensibilities

    Sensibilities come from closely held values and personal preferences, family experiences, a lifetime of forging personal style, special places, environment factors and a thousand other influences that make one like or dislike someone or something.

    On my father's side I had my Grandma's warm arms and bright bluebells, and on the other side I had my Aunt, the original upcycler. She was an artist with a fantastical garden. Her garden was her masterpiece, an Impressionist's dream, with wide swaths of contrasting colors and textures. Dotted with art and hidden rooms, she was a leader before there were pins on Pinterest to show us the way. Paradise even had a snake. As little girls, my cousin (her tow headed daughter) and I (my hair almost black in contrast), in harmonic, high pitched squeals of terror, begged her to slaughter a terrifying snake. Sssssaid snake carelessly flicked its forked tongue our way. We showed her where it went and she taught us that we were the pests in her garden, and the garter snake the one who belonged.

    Sensibilities are visual and tactile. They come from admired artists, stylists and interior designers. Mix or match color (contrast or ombre), scale (small, medium or large), texture (soft, fine, glossy, coarse, matte) style (traditional, transitional, eclectic, contemporary, modern) and purpose (active youth, dog friendly, entertaining, respite, hospice or retreat). If you think about it, the land is your canvas, the plants are your separates, the sections are your rooms and the garden is your stay-cation. 

    It is in our best interest to value the residents of the garden, from bees and other pollinators for fruiting to snakes that control rodents. When action follow values, a garden is made more vital. Show concern for fragile migrants. Monarch butterflies are under particular stress from reduced habitat (development, herbicides and rights-of-way mowing of their only "whole life cycle" host plant, milkweed) and disease. Garden for Monarchs, so carelessly perched on the brink of extinction that our grandchildren, or our children's' grandchildren may only see them in museums or images. Please find a place for milkweed (a misnomer that hardly does justice to a beautiful plant). Find regionally native milkweed; plant it in a corner of your garden; plant it and they will come!

    Perhaps the most sensible reason to garden of all, there are the health and well being factors to consider. Studies now show that gardeners experience emotional and physiological benefits from gardening - "Immunity, blood pressure and peace, Oh My!" ...

    Are we still having fun? Not surprisingly, I am. My garden is a reflection of my scents, cents and sensibilities, my recipe: a dash of Grandma, a pinch of Italy and pound of Aunt Gean, mixed with resilience, availability and vigor, beautiful and strong. If you design a garden around your sensibilities, you'll have a place worth loving. Apply what you know about design and you're sure to create a garden worth visiting.

    In Practice

    I highly recommend Pinterest as a starting place for your garden plan - there you may find a style you love. Keep a visual firmly in mind as you add and subtract your way through your space. I began by looking at landscapes planned by Piet Oudolf - I found his naturalized, low water, deeply rooted, tightly packed, odoriferous gardens to be worth emulating on a smaller scale.

    I also had a collection of pottery fish on stakes to incorporate. With the images of Lurie Garden in mind and fish in hand, I turned to a few favorite online resources with the goal of selecting 2-3 plants to populate each of several garden layers. I wanted a broad carpet of ground covering or low growing grass to simulate waves of water (for the fish), low-mid perennials, mid-high shrubs and sky high trees. Sometimes, we, I, as an unapologetic plant collector, tend to add hundreds of plants, no two alike. Sadly, I have learned that undisciplined plant collecting leads to chaos and not to an aesthetic result. (I’m trying to curb my plant addiction in my bed additions, but it’s so very difficult).




    To help me curb my plant addiction, I learned how to approximate a landscape plan, a horizontal map of plant symbols drawn to scale. A landscape plan keeps you focused on your goals, like shopping with a list and not when you're hungry keeps you on task and on budget. I use photo manipulation apps (Photoshop) to visualize the vertical appearance of plants at maturity. I make simple mash ups, scaling plants using an object of known height, like an existing shrub or my fish in the picture for scale. Remember that it is nearly impossible to illustrate the way the garden will look seasonally, because everyone photographs plants when they’re in bloom, making it very difficult to visualize seasonal changes. Think of seed heads and plan for seasonal interest.

    Planning seems to have worked well. On our last expansion into the lawn, our bed went from denuded to lush in the first season. However, the majority of what we planted was seed grown, regionally native stock. Given challenging site conditions, a cool & wet spring, followed by a hot and dry summer, I think that careful planning and proper planting of quality native plants produced excellent results, and not by coincidence.
     

    Repeatable

    For there to be method in my madness, the results need to be repeatable. I believe they are, given other examples I have found in research and locally in friends' gardens. A wealth of online resources and wonderful books are filled with fabulous detail on native plants (wildflowers and more). A good place to begin your research is at the Lady Bird Johnson Wildflower Center (www.wildflower.org). The Wildflower Center has a data base of wildflowers, and boxes you can select to filter the search set for a variety of characteristic.

    For example, a search for the area of Folsom, California produced more than 2,500 results (individual native plants). By height range, plant type  (shrub, tree, herb, etc.) and condition (sun, shade, wet, dry, sand, clay, and etc.) you may "drill" down, truncating the list to those native plants most likely to survive the site conditions. The Wildflower Center allows for refinement by many other botanical characteristics.

    The California site requires special consideration for the prolonged western drought. The subset of dry soils narrows the list to 474 plants. A comparison of plants in four garden layers, can be cross checked for local availability. From there, it's a matter of a personal preference, keeping in mind scents, cents and sensibilities.

    A sample selection is shown below:












    • Carpet Layer: Sand Verbena  & Angel Trumpets purple & white.


    Notes:









    • Mid Layer: Angelica , Wooly Pod Milkweed  & Showy Milkweed  

    Notes:











    • Eye High Layer: Serviceberry,  Bush Anemone , Western Spicebush, Buttonbush  & Red Currant.











    Notes:







    • Sky Layer: Acacia Tree, Honey Locust - Sunburst thornless Gleditsia triacanthos var. inermis variety  & Douglas Fir.  (May have existing Douglas Fir, iffy, but Cali has lost so many, you may want to try for the sake of preservation.)

    Notes:
















    Additional Regional Resources

    Best booklet: A California-Friendly Guide to Native and Drought Tolerant Gardens (http://lvmwd.com/home/showdocument?id=711)

    Santa Monica Parks Design - incorporates the styling of my all time favorite designer, Piet Oudolf. You may find and apply elements in this plan in your garden, wherever it is, using his well laid out examples and regionally native plants. The documents include the following particularly helpful design elements:

    1. - Slope Planting Detail
    2. - Park Project Plan
    3. - Garden Walk Plan in Action

    (http://www.santamonicaparks.org/design-1; http://www.smciviccenterparks.com/design/)

    Learn where to purchase plants. No matter where you are, there are resources to help you find plants that are native to your region. Seed collecting and wild harvesting is considered to be poaching - often illegal, so make sure what you are buying is locally produced from seed (preferred) or by cloning (from cuttings or tissue cultures. Cloning produce identical copies - good, but more susceptible to problems, if a pest or disease attacks one - it attacks them all). Connect with your local chapter of Wild Ones Natural Landscapers, Inc., Native Plant Society, Environmental Protection, Fish & Game, USDA Government Plant Files, local parks, public works & planning offices and many more data sources for information you can use in your garden. Be prepared, creative, personal and amazed at what you can accomplish in your garden.

The Diaper Debate Super Absorbent Polymers: To Harvest or NOT to Harvest, Diaper or Bulk, Urine Soaked or Not...


The Diaper Debate
Super Absorbent Polymers
We’ve all seen the Garden Hack where a disposable diaper is used for its absorbency crystals, to absorb and preserve moisture in potting containers. Sometimes called Petroleum (or Polymer) Absorbency Material  (PAM) or Super Absorbent Polymer (SAP), we are talking about the crystals that swell to 300 times or more their weight in liquids. The way these crystals are supposed to work, the gel absorbs moisture in the good times and transfers water to the plant when the soil dries out. SAP is also used in disposable diapers to keep moisture under the cover and away from baby, hence the garden hack - to harvest SAP. Recycling diapers is an interesting notion, but I have several questions that need to be answered before I'll be diaper mining.  Does it work that way it's supposed to work, is it cost effective to harvest SAP from disposable diapers, and if the diaper has been used, is it safe to use in plant soil?

Just how much SAP is in the average disposable butt cover anyway? It turns out that the answer to the question regarding the SAP content in disposable diapers is variable - at least two or three fold - too much for the landfill and not enough or too much for most soil mixtures. A diaper holds 10 to 15 grams of powdered SAP, enough to absorb 106 - 159 oz of liquid, so I can see where it would matter what the gel absorbed.


How much does that diaper cost though? The most absorbent diapers cost between 25 and 50 cents per diaper. Harvested from a diaper, SAP would cost about $1.25 per ounce on average (if you could actually recover all of the SAP from the diaper). I found several offerings of bulk SAP readily available online for about $10 per pound, or $0.62 per ounce. In contrast, bulk SAP is less than half the cost SAP from diapers.

Should we try to recycle the SAP in disposable diapers from an environmental and practical standpoint?  SAP is petroleum based, and not sufficiently biodegradable for environmentalists. Therefore, if the SAP were somehow harvested, recycled and packaged for use in gardening, it could be a very good thing. Disposable diapers, specifically those made for use in swimming pools, may be washed two to three times and air dried (NOT those that are soiled) before they begin to fall apart. It would be possible to harvest cleaned SAP from swim diapers, although they owe the fact that they do not swell to their lower amount of SAP. It does raise the question though... Can the home gardener clean and harvest SAP from regular disposable diapers for use in soil mixtures? (There are several academic exercises online with instructions for harvesting SAP from clean and dry disposable diapers if that is your goal.)


Yuck factor aside, can SAP harvested from used and wet diapers be used in planting mixes? Apparently, urine may be an acceptable, effective and organic fertilizer. “Urine is chock full of nitrogen, potassium and phosphorus, which are the nutrients plants need to thrive—and the main ingredients in common mineral fertilizers (as reported in Scientific America, July 23, 2010, Mara Grunbaum). An adult on a typical Western diet urinates about 500 liters a year, enough to fill three standard bathtubs. And despite the gross-out potential, urine is practically sterile when it leaves the body. Unlike feces, which can carry bacteria like salmonella and E. coli, urine poses no health risks—astronauts on the International Space Station even drink the stuff—after it was purified.” (see footnotes for citations)

My next question is, how much urine is appropriate for use in a container, like a hanging basket?A study garden shows that “The urine that one person produces can fertilize about one square meter of soil a day? An output of 1.37 liters or feeds approximately 10.67 square feet of garden area per day. Converted to English units, that amounts to 46.33 ounces or 5.79 cups of urine per day. At that application rate, that equates to just over 1/4 cup of urine for a two gallon planter. Since hydrated gel is nearly all liquid, the SAP from one diaper could hold up to 20 times more urine than is needed. Gee Wizz - that's a lot of nitrogen!
Given the variability in the urine production (how would you figure the volume of urine in the used butt cover?) how would you apply the appropriately amount of “fertilizer” for your container? I guess you can come close with calculations like those used for the two gallon planter, or you can reduce urine content by washing the gel. Are you really willing to wash disposable diapers? The main risk would be that the diaper could rupture. Water logged SAP would NOT be good for your plumbing.

A very thorough counterpoint is contained in the analysis, “Miracle, Myth or Marketing: Super-Absorbent Water Crystals” by Linda Chalker-Scott, PhD, who says,
  • "Cationic PAM hydrogels should not be used in gardens and landscapes."
  • "Unfortunately, on-the-ground conditions can prevent PAM hydrogels from functioning optimally. Fertilizers and other dissolved substances can interfere with hydrogel water-holding capacity. Hot, dry weather conditions can lead to increased degradation and decreased effectiveness of PAM hydrogels. And for every success story, one can find a situation where hydrogels have failed to function."
  • "The best news for those of us managing a home garden or landscape is that simple changes in management practices are often superior to using polyacrylamide hydrogels. In several cases, alternative water management strategies had higher success rates than usage of PAM. These strategies were as simple as adding 2 liters of water when planting Pinus patula seedings, or providing wind protection to reduce water stress in muskmelon. More commonly, mulches (especially organic) were rated superior to hydrogels in terms of erosion control, enhancing water infiltration and conservation, plant growth and establishment, and nutrient value."
The data on efficacy is mixed. According to multiple sources, including one published by Global Post, SAP can be so good at absorbing moisture that it can even over dry skin causing contact rashes and dry cracked skin in diapered babies. If that’s the case, can we depending on these crystals to impart moisture to plants? Maybe. I think it would depend on the plant structures, whether they are soft or woody. Other research has shown that SAP can be effective in delaying moisture evaporation and in supplying moisture to plants. Another study showed that results depend on how much SAP is used - more is not better and can cause plant damage as the swelling gel forces out oxygen, filling all voids with water logged gel. “Eventually, regarding many studies done about super absorbent polymers in green space, it can be concluded that using this substance lonely, or with incorporation of other xeriscaping methods, in particular in arid and semi arid green space has many merits." It turns out that there are many factors determining the amount of gel required for the best performance - more than soil volume and urine content (Sivapalan 2006; Zohurianmehr 2010 as cited in the Iran study). 

Finally, returning to the questions posited in the beginning, “To Harvest or NOT to Harvest, Diaper or Bulk, Urine Soaked or Not…” After careful review of the issues, I will not be diaper diving to harvest SAP from unused diapers at twice the cost of SAP purchased in bulk. Nor will I be gathering urine soaked SAP from used diapers. I may not even use SAP purchased in bulk now that I realize how variable the results can be and how many factors need to be considered before measuring out the first teaspoon full of dry, urine free crystals.

I have high hopes for a market response to the very real potential for producing recyclable absorbent materials that are earth friendly.

If (when) you find errors, or have comments, I really appreciate feedback, especially if you can think of an easier way to present the information. Believe me, I did not imagine the issues would be this complicated.

3- 21 Disposable Products Toy Can Reuse, by Paul Michael on 14 March 2012, http://www.wisebread.com/21-disposable-products-you-can-reuse
5- If I assume a depth of about 1/2 foot of urine penetration into the soil to approximate the volume of soils for the purpose of comparison, the volume were talking about is approximately .152 cubic meters or 5.37 cubic feet. Restated, the urine produced by an adult fertilized 5.37 cubic feet of soil. There are 7.48 gallons in one cubic foot, more than I thought. Relative to the soil in a two gallon planter, if 5.79 cups of urine was added to 5.37 cubic feet of soil per day, how much would that be for just two gallons? 5.79 cups is the amount of urine that was added to 5.37 cubic feet of soil per day. By dividing the gallons by the volume, we arrive at a rate of 1.08 cups of urine applied to each cubic foot of soil. A two gallon container holds approximately .267 cubic feet. .267 cubic feet per planter X 1.08 cups per cubic feet in the research = .29 cups of urine per day for a two gallon pot.
