Yard work, exercise and fitness: the unintended work-out

Self-tutoring: the tutor shares about yard chores.

Yesterday, I thought perhaps I wouldn’t get enough exercise. I thought wrong.

For the seeds I found in our shelves, I decided to open up more garden space from a rectangle of the lawn. It was a spontaneous decision that meant using the shovel and pick-axe.

Turning over the sod took me about 45 minutes. A pick-axe is handy to have for such jobs.

When I was a kid, my Dad had a roto-tiller that would’ve done the job in under 10 minutes, no sweat. We lived in a farming place, then. Now we don’t, so I till by hand:)

I’ll keep you updated on what I plant; I hope to start today.

Lifestyle, yard work: watering reflections, part 0

Self-tutoring about watering: the tutor reflects….

I can’t remember when summer 2018 started (see my post here about when summer starts); irrigation is in full swing. (I began about this year’s watering efforts in the post here.)

I’m no pro at watering, but I’ve observed a few helpful hints:

  1. When working with several sprinklers, turn off the one in a sensitive area (eg, near the sidewalk) first. If you turn off another one instead, the one near the sidewalk may then receive more water, and spill beyond the yard.
  2. I typically water one spot for, at most, around 30 minutes. I suspect once it’s soaked, the rest of the water probably doesn’t help; rather, it may just leach out nutrients to runoff.
  3. Single plants or bushes that need water but are outside of the main sprinkling areas, I do with a watering can. I don’t sprinkle the whole yard, just main areas.

Best of luck with your yard:)

Biology, composting: immobilization vs mineralization

Organic groundskeeping leads to self-tutoring. The tutor defines two terms connected with composting.

In a properly functioning ecosystem, nutrients are constantly recycled – they are used by one organism, then released back to the soil to be retaken by another.

Immobilisation is the temporary possession of a nutrient by an organism (typically not a plant, but rather a decomposer). The decomposer needs the nutrient for its own life process. While the decomposer is alive, the nutrient it contains is unavailable to the surrounding plants.

Mineralization is release of nutrients to the environment. Now they are available to plants.

The eventual result of decomposition is mineralization. During decomposition, however, immobilization may happen.

Biology: what is a cultivar?

Horticulture can lead the amateur to self-tutoring. The tutor discusses the idea of a cultivar.

Cultivar literally means “cultivated variety.”1 In my mind it refers to a plant commonly grown, that you, also, can buy and grow, either as seed or already a plant.

A cultivar may be grown for fruit, beauty or other benefit. However, offspring from its seeds may – but may not – emulate its own qualities. Similarly, the cultivar may not reflect its parents’ traits. It may have been chosen and propagated specifically because, in some desirable way, it broke from its parents’ characteristics.

Seedless grapes or oranges might be examples of cultivars. Apparently, the tree that produces seedless oranges cannot self-propagate by pollination. Perhaps it can be reproduced by cuttings; another option might be grafting. However it’s propagated, the seedless orange tree is cultivated – hence, a cultivar.

Lifestyle: when to harvest apples

Lifestyle is continuous self-tutoring – for me, anyway. The tutor comments about when he chooses to pick apples from the tree.

When my first son was born, we planted him an apple tree. Without having to compete for sunlight, or space, it’s prospered over fifteen years. Today it’s heavily laden with apples, which I’m about to pick.

When to harvest the apples is often a question. I’ve read it’s best to wait until a few fall off, but for me that’s only one of three cues:

  1. A few apples fall off by themselves.
  2. Picking one, it tastes sweet.
  3. The first fall storm has come.

Our first fall storm was yesterday, of course: for me, therefore, the time has come to harvest the apples. I’m not recommending these guidelines, but they’re how I decide.

Lifestyle: watering the lawn: best time and way

I’ve recently taken self-tutoring about lawn watering. The tutor shares some discoveries.

On the west coast, summer is often very dry. Typically, if the lawn isn’t watered, it will go brown.

Where I live, we have watering restrictions. On the days I’m allowed to water, it’s either 5-9am or 7-10pm. I looked up when is better. Condensed, here are the hints I found about watering the lawn:

  1. Water in the morning before the heat of the day.
  2. Use a pulsating sprinkler: the water spends less time in the air → less loss to evaporation. However, for new grass,
    use oscillating sprinkler → gentler on the budding seeds.
  3. Water to soak 6 inches (15cm) deep.
  4. Water no more than twice per week.

I don’t water every part of the lawn every time; sometimes I only water the weaker patches, maybe for twenty minutes each.

Oak trees: do red oaks produce acorns every year?

The tutor shares the answer to a question he’s long harboured.

Generally, red oak acorns take two years to mature. Does that mean the tree drops a crop of acorns only every second year?

According to Cathy Blumig of outdoorlife.com, red oaks flower every year. Therefore, they certainly can produce acorns every year: this fall’s acorns will be from the flowers of sixteen months ago, rather than from the recent spring. Next year’s acorns, in turn, will be from this spring’s flowers.

While the quantity of acorns from a red oak may vary from year to year, the tree can definitely produce them every year.

Botany: black walnut: juglone

The tutor researches the effects of juglone from black walnut trees.

Juglone is a toxin produced by the black walnut tree; it’s found throughout the tree and in its leaves, shells and nuts.

Apparently, to humans eating the walnuts, the juglone is not a problem. However, it enters the soil from the roots of the black walnut tree, as well as from its leaves, twigs, and even pollen falling to the ground – not to mention the nuts and their shells. Some plants, such as tomatoes, potatoes, lilacs, and rhododendrons, can be damaged by the juglone.

To be safe, composted matter from black walnut should wait a year or more before application.

Horses are particularly sensitive to juglone; neither black walnut shavings, nor the husk fibre, etc, should be used in a horse’s environment.

Yard work: wood bugs

The tutor brings up a species (two, actually) that are common here.

In BC, “wood bug” refers to either of two animals: the sow bug or else the pill bug. They are very similar, so here, they share the handle “wood bug”. However, the sow bug has two “tail appendages” – the pill bug doesn’t. Compared to the sow bug, the pill bug is rounder in shape, so able to roll into a tight ball for defensive purposes. I’d say that, around here, both are very common.

Interestingly, sow bugs and pill bugs are crustaceans: they are more similar to crayfish, crabs, or lobsters than to insects. They have seven pairs of legs. They eat, primarily, decaying plant material.

Being crustaceans, sow bugs and pill bugs need moisture. Therefore, they are found in damp, dark places, and are apparently more active at night. Conveniently, the same conditions that maintain moisture also promote decay.

Even pestcontrolcanada.com points out that sow bugs and pill bugs are helpful to the environment because they recycle nutrients – in some cases, even more beneficially than earthworms. University of Kentucky says that they are an eyesore, but really not a problem. Their presence indoors is symptomatic of a problem – wet conditions that foster decay.

I certainly don’t see wood bugs, as both sow bugs and pill bugs are called around here, as pests. They are benign recyclers of the tree material constantly raining down on us from the Douglas firs and others. Out in the yard so much lately, I’m noticing them when I move things, etc. Of course, this summer’s been quite damp: we’ve had rain most weeks.




Botany: can creeping buttercup flowers be orange?

The tutor discusses a find yesterday that has him guessing.

Yesterday, clearing foliage from between some paving stones, I noticed an orange flower. In fact, it was going to seed: the petals had collapsed, but still clung to the pistil. There seemed to be five, and they were orange. This plant was among a colony of creeping buttercup, and seemed to be that, as well. (Interestingly, none of the rest of the colony is flowering, so there were no other blooms for comparison.)

The question: can creeping buttercup flowers be orange? I seem to recall they can be, but wanting confirmation, I searched the internet. Two sites suggest that creeping buttercup flowers can be orange: mountainnature.com and kuleuven-kulak.be

I’ll be talking more about yard finds in future posts:)
