Appreciate the season

/ Robinne Weiss / Leave a comment

Drizzle-soaked hebe.

It’s another grey, damp day in a string of grey damp days. We’ve had little rain, but almost no sun, either. Though my last blog was about spring, this weather reminds me it’s still winter.

I’m itching to get out into the garden, to plant seeds, to get on with the business of springtime. The weather hasn’t been cooperating.

In a way, that’s good. It is too early to plant, to early to turn the soil. The weather reminds me to appreciate what winter has to offer—the excuse to stay indoors and sew, the opportunity to play board games and read books, a reason for a mid-afternoon cup of tea. I forget to value these things when I have them, instead looking forward to the next season of frenetic activity. Sometimes I need a week of fog and drizzle to remind me.

Smells Like Spring

I know, technically it’s still winter. We’re still likely to have icky, cold, wet weather. There will be ice on the water troughs, and frost on the grass in the mornings. There are still plenty of weeks left in the skiing season. And I won’t even think about planting anything out in the garden for at least six weeks.

But yesterday smelled like spring.

That heady combination of lanolin, damp soil, and cut grass.

It sounded like spring, too, with magpies warbling in the trees, swallows chittering overhead, and lambs bawling in the paddocks.

It is not spring. Not yet. But the days are lengthening and the first daffodils are beginning to bloom. It’s time to finish all those indoor winter projects. Spring is on its way.

Still Life with Insects

/ Robinne Weiss / Leave a comment

I’ve written and discarded half a dozen blog posts over the past week. Nothing seems to be quite right. Out of ideas, I resorted to the book of 500 writing prompts I created for my daughter. A random stab at the non-fiction section of the book brought me to the question: What objects tell the story of your life?

I tried to encapsulate everything in four objects:

The fiddle: made by a neighbour in Panama, given to me for my birthday by my husband. The fiddle not only tells the story of our years living and working among the incredible, resourceful people of Panama, but also tells the story of my lifelong interest in learning to play the violin…an interest which always ended up being pushed aside for other interests. Because I’m interested in learning so many things, there simply aren’t enough hours in the day.

The beetle puppet represents my insatiable curiosity about arthropods, and how that curiosity has bled into my other interests. Peanut butter jars full of bugs on my dresser when I was a kid led to the entomology degree, which led to teaching about insects at Penn State University, and then starting the Bugmobile. And the puppet is only one of many insect-themed and inspired artistic projects I’ve done over the years, as art and science mingle in my brain.

The gardening gloves speak of my weeding addiction and my love of growing food. The gloves are never more than a month or two old, because I wear through them in that time. I think that says it all about gardening for me.

The rock represents adventure, the natural world, and the wild places I have visited and lived in. Like me, the rock has traveled far and has been changed by the stresses it has experienced along the way.

Happy New (Garden) Year!

I love the month of July; it’s the beginning of the garden year in my mind, because it’s the month I plan the garden and order my seeds. It’s been a few years since I blogged about my garden year, so I figured it was time to do it again. I unearthed this little graphic my husband helped me create a few years back, showing my annual planting and harvesting schedule. It has changed a little since then, and I notice some crops, like garlic, are missing from it, but it’s still a fairly good indication of my year in the garden.

I struggled the first few years here. Coming from the Northern Hemisphere, I had no idea when I should plant things. And the idea of growing vegetables over winter was foreign to me, too.; gardening in Minnesota and Pennsylvania is sharply seasonal. It’s seasonal here, too, but much less dramatically so.

Instead of growing a ton of spinach over the summer and freezing it for winter, I learned to simply plant small quantities regularly throughout the year, for a perpetual supply of fresh greens. Same with lettuce, chard, broccoli, cabbage, and cauliflower.

Today my garden year ebbs and flows, but there is never a down time in the garden. There is always something to plant, weed or pick. The end of last year overlaps with the beginning of this year, so while I plan my seed order, I’m harvesting the lettuces, broccoli, leeks and other late crops planted in the autumn, and I’m weeding the garlic and broad beans that will be harvested in the coming spring and summer.

Sometimes I miss the complete downtime of gardening in Minnesota—the winter lull when there’s no need to go out and weed in the cold. But only sometimes. The never-ending garden year here has its perks in garden-fresh vegetables year-round.

To the Beach

/ Robinne Weiss / 1 Comment

While all you folks in the Northern Hemisphere are flocking to be beach for a swim and some sun and sand, we are shivering down here in the dark days of winter. But that doesn’t mean we don’t go to the beach.

Research from England has found that people living by the coast have better physical and mental health than those living inland. I can certainly understand that.

Growing up three hours’ drive from the beach, I visited the ocean about once a year. My husband, raised in the midwestern US, doesn’t remember seeing the ocean until age twelve or thirteen.

Today, we live a mere four kilometres from the beach. When the wind is calm, we can hear the surf. When the wind is high, we can smell the sea. Even without research to back us up, we’ve learned to head to the beach when we’re stressed.

Our beach isn’t a white-sand swimming beach—it’s made of cobbles, and the waves pound viciously on the shore. It’s not a place to swim, nor really a place to sit for very long (those rocks get uncomfortable fast). It’s a place to walk. A place to search for wave-polished rocks in glittering colours. A place to watch sea birds, dolphins, and the occasional seal. A place to leave all the stress of daily life behind (I challenge anyone to remain stressed while watching dolphins cavorting in the waves).

Researchers point to the calming blue colour, the hypnotic sound of waves, and the cultural context of the beach to explain its calming effect. But for me its influence is more profound. Our beach is usually free of other people—on a busy day you might see four others. From the beach, it is difficult to see any sign of humans at all—the odd bit of flotsam, but not even much of that. On our beach, the world is reduced to sky, water, and rock, shared only with wildlife. It’s easy to imagine the world is in better shape than it is. It’s easy to believe the vast ocean will endure, in spite of human stupidity. It’s easy to think those rare Hector’s dolphins, which we see nearly every time we visit the beach, are actually common. For the space of time we inhabit the beach, all is right in the world.

It doesn’t last, of course, but it’s good to have that escape so close at hand.

Beautiful Brawny Barnacles

/ Robinne Weiss / Leave a comment

My daughter and I went for a walk on the beach after school yesterday. It was chilly, but calm, with a clear mid-winter sky and dolphins in the surf.

Washed up on the beach was a large tree stump crusted with barnacles whose colours mirrored the evening sky. The size and profusion of barnacles indicate the tree was lodged in the water for a long time before it was hurled onto our beach.

Barnacles are strange creatures. They’re crustaceans—kin to crabs, shrimp, and lobsters—but they don’t look anything like their relatives. Barnacles have given up the ability to move on their own (after a brief mobile larval stage), and instead settle down in places where the water moves around them—intertidal zones, the backs of whales and the bottoms of ships are popular barnacle real estate. Instead of having to wander in search of food, moving water carries lunch to the barnacles, and they filter it out of the water with feathery appendages called cirri.

Staying put in places where waves pound day in and day out isn’t easy. Barnacles produce a ‘glue’ that’s one of the strongest natural adhesives around. With a tensile strength of 35 N/mm2 (5000 psi), it rivals the best commercial epoxies. In a strange quirk of biology, the glue is produced by a gland at the base of the barnacle’s antennae, and so the animal is glued head-first to the substrate. Once glued to its home, the barnacle forms a ring of plates around its body to protect it (this is all that is left of the barnacles pictured here—the animals themselves have died).

There are costs to gluing oneself in place. Unlike other sessile animals like corals who release their eggs and sperm into the water for fertilisation, most barnacles rely on internal fertilisation. To reach their neighbours and manage this feat, the hermaphroditic (both male and female) animals have penises that can be 8 times the length of their bodies. Until recently, researchers thought this was the only way barnacles could reproduce, but in 2013, a study found that at least one species of barnacle (with a particularly short penis) can capture sperm from the water if it’s too far from its neighbours.

Barnacles are of human importance. They encrust ships, leading to increased drag and fuel costs. But their habit of attaching themselves to all sorts of debris can also be used forensically to track marine wildlife like whales and turtles, items from shipwrecks and airplane crashes, and marine debris. Additionally, barnacles are considered culinary delicacies in Spain, Portugal and Chile.

Beautiful and brawny, weird and wonderful, barnacles always make me smile.

Backyard Biodiversity

Craterium minutum

I know it’s been a good weekend when I arrive in my office Monday morning to find my microscope in the middle of the desk, and dirt and bits of plant material strewn about.

It means I’ve been outdoors, seeing cool stuff, identifying plants, insects, or other organisms.

Once you start looking at and identifying what lives around you, the variety is astounding. A glance at the citizen science website iNaturalist shows a pile-up of dozens of observations at our address—and those are only the species we’ve bothered to upload.  I’ve identified 58 species of weeds in the vegetable garden alone. We have half a dozen slime moulds, dozens of fungi and lichens, who knows how many insects and other invertebrates. Then, of course, there are the birds, rats, mice, stoats and other vertebrates. I’ve never bothered to make lists of anything beyond the weeds.

So here in the dark depths of winter, I’ve decided to start a comprehensive list of the biodiversity on our little acre and a half. It will take time. It will require my microscope and many Monday mornings brushing dirt off my desk. But wouldn’t it be cool to know exactly how many other species we share this patch with?

And though many of the species I’ll put on my list are ones I’ve noted many times before, I’m sure some will be new and surprising, like the beautiful slime mould, Craterium minutum my daughter found last week.

Because, the truth is, we needn’t travel far to find natural wonders. We merely need to look closely and have a sense of wonder.

Here Comes the Sun

After weeks of grey, unending drizzle, we’re finally seeing a bit of sun. Mushrooms abound in the yard, revelling in the dank mist we’ve been swimming through for a fortnight. We are all eagerly awaiting passing of the solstice and the lengthening of the days.

Though it is still pretty dark and drear, and the days will still be short for some time, there are signs of the spring to come.

Lambing has started. This is the time of year when the neighbours grow noisy, with lambs and ewes calling to one another day and night.

The preying mantids are gone, but their egg cases are dotted around the yard, promising a healthy population of my favourite predators come spring.

The daffodils and snowdrops are coming up, and I’ve even seen them blooming in other people’s yards.

And tomorrow is the solstice. Friday, the sun will remain above the horizon fractionally longer than it did the previous day. We’ll be on the upswing.

Beautiful Basket Fungus

/ Robinne Weiss / Leave a comment

Mature fruiting body

One of my favourite fungi is Ileodictyon cibarium, the basket fungus, native to Australia, New Zealand and Chile. We have been treated this year to an amazing display of these fungi in our recently wood-chipped pond garden. Usually we don’t notice them until the fruiting bodies are fully formed, but because there are so many this year, we’ve been able to watch their whole emergence, from egg-like volva to lacy soccer ball.

Aside from their striking look, there’s nothing particularly lovely about these fungi. The basket fungus is in the family Phallaceae, also known as the stinkhorn fungi. Members of this family—you guessed it—have a foul odour (and many are phallus-shaped). The carrion or dung-smelling fruiting bodies attract flies to disperse the spores. Supposedly, the young fruiting bodies are edible … but not very tasty, as you can imagine.

Immature volvae

In spite of their smell, basket fungi have a certain celebrity status, owing to their remarkable structure. In fact, in Hagley Park in Christchurch there used to be a play structure in the shape of a giant basket fungus. I’m not sure if it’s still there—my kids don’t frequent playgrounds anymore—but it was always a favourite with my kids.

Conversation Overheard in the Park

Every time I see these trees, I think they look like old men sitting around talking.

“Remember,
When we were just saplings?
How we thought the wind was so strong?
Thought it was going to blow us right over.”

“Well, it almost did, didn’t it?
Joe was nearly bent in two
In the cyclone in ’17.”

“Aw, he was a youngster.
He came right.”

“Ah, but ‘17 wasn’t half as bad
As that big blow in ’44,
When Carol and I lost nearly half our limbs.
I thought the rot might get us after that, you know?”

“I heard a pair of poplars the other day,
Young things,
Hardly able to grow lichens yet,
Complaining about the wind.
Ha!
What do they know about wind, I thought.”

“They don’t make wind like they used to.”

“Or snow.
I remember snow so heavy it took off branches.”

“Yes, but don’t you think the sun was brighter back then?
When the sun was up it was up,
And you knew it.
Not like this weak sun nowadays,
Hiding behind clouds,
Hardly enough to photosynthesise with.”

“Absolutely. Water tasted better, too.
When we were young.
Cleaner.
Modern water just isn’t the same.”

“Do you remember those kids?
The ones who used to climb right to the top of my branches?”

“Then there was that one,
The boy with red hair,
Who fell.”

“Broke his arm, didn’t he?”

“Do you think that’s why they did it?
Why they cut us down?”

“Don’t be stupid.
That was years ago.
Humans have short memories.”
