Antarctic forest plant maintenance

 
Today I cycled to the greenhouse for the first time in 2023. The temperature soared to 88F. I packed a pair of short pants for the ride home, but I prefer to wear sturdy long pants for work at the greenhouse. I’m frequently on my knees tending plants or weeds, the extra padding of long pants is much more comfortable than bare knees on hard concrete or gravel. The ride was quite pleasant, although the breeze from the south was sharp at times.

The first task assigned to me for the day, by the Curator, was to collect some packets of beneficial insects -  Amblyseius cucumeris - from the pots in room C2 and relocate them to sick plants in room D4 (the desert room). One plant in D4, in particular, is beset by mites which are sucking out the sap and killing the leaves. One entire branch had been denuded. I attached the packets to the stems of the 4 plants to encourage the A. cucumeris predators onto the infested plants, to find the offending mites, and eat them.

My second task was to trim one of the ground-cover plants in D1, representing the Antarctic Forest biome of New Zealand and New Caledonia. This particular plant from New Zealand is noted for its unique blue pollen: Fuchsia procumbens. Since we’re in the spring season, the plant had many flowers each with tiny anthers sporting intense blue pollen grains. I was so lucky to see it!



My third task, and the most tiring, was to refill the bin for potting soil mix 1a. This is the most frequently used soil mix with a ratio of 3:2:1 of coconut coir, pumice, and sand. The coir is shipped in tightly compressed blocks which have to be rehydrated and broken apart by hand. My hands were very sore and cramped by the end of the day. I also had to find and transport the sand from a distant part of the building. I’m grateful I know where such things are stored. I didn’t have to ask anybody for directions to complete the chore. I finished the job with a pretty full bin of fresh mix.

While mixing the soil, Al and B were re-potting an unidentified desert plant. I guessed it was a cactus since each spine arose from a bud with a pair of spines. But Al said, “no, it is a euphorbia.” I was embarrassed to be wrong, again! I vow that I will learn to recognize a cactus from a euphorbia!!! This plant had “spikes”, arranged in pairs, with no areole bump = euphorbia.

Difference Between Cactus and Euphorbia - Comparison Summary

Having finished the soil mix, I went on to shore up the vine I’d repotted the prior week. I wound the vine around the tripod I had constructed, attaching it to the legs of the tripod with ties using stretchy green garden tape.

While on the bromeliad bench, my attention was alerted to a coffee plant growing on the bench, it had bright red coffee beans!

Also on the bromeliad bench in room C2, Al mentioned some of the cork panels are falling off of the trellis grid. The cork panels hold a number of Tillandsia plants and bromeliads. I found a step ladder to climb up on the bench and noted the fine wires which had been used to hold the cork had rusted through. But, running out of time and material I was unable to finish the job. Really, the whole display needs to be taken down and re-attached using non-ferrous wire.

Before I had a chance to clean up my mess on the bromeliad bench, I absentmindedly allowed the door to close and lock me out of room C1/C2. Director had pulled the wedge out from the door, allowing it to fully close as I went to find more wire. This is an example of how useful an ID badge will be.

Later in the afternoon at home, I completed the process to log on and update a temporary password for my U of M account online. With the account, I will be able to get an ID badge under the sponsorship of Director and the CBS department. Once the application is approved, I’ll head over to the student center to get photographed for the ID badge.

A Sensitive Plant and Common Weed

Mimosa pudica, also commonly called the sensitive plant  was a popular houseplant when I was growing up in the 1970s. It was popular for its ability to quicky change shape by folding up its leaves to protect them from herbivore predators. At the slightest touch the plant is able to expell water from special cells in the leaves, changing the shape from frond-like to a stick-form. The plant creeps along the ground, never for than a foot or so in height. In tropical parts of the world this plant is considered and invasive weed. Today, as I was treating plants to remove pests I happened to touch the leaves of a Mimosa pudica , one with a pretty puff-like flower. Sure enough, the leaves all folded up to almost nothing. Mimosa pudica , the sensitive plant Other more routine chores during my four-hour shift at the U of M Conservatory included cleaning three plants of Hibiscus clayi, native to Hawaii. These three plants in particular have suffered repeated infestations with a variety of in...

A Thames River Walk Through Time: Repurposing Tow Paths

I love it when old technologies are repurposed to solve entirely different problems. A perfect example is the extensive system of canals and tow paths throughout England. Before the Industrial Revolution and the advent of railways, these canals were built to transport goods between cities and towns. Narrow boats pulled by horses or mules along tow paths were a common sight. Today, however, these tow paths have found a new purpose: recreational walking. They offer picturesque routes through the English countryside, allowing people to explore the beauty of the canals and rivers. The commerce that once flowed along these waterways may have shifted to railways, but the paths themselves continue to serve a valuable function. This year, I had the privilege of joining three other hikers on a journey along the River Thames tow path, from the city of Oxford to its source, a distance of about 50 miles. Farther upstream, the river gradually narrowed, eventually transforming into a swollen creek b...

Plantulary: Botanical Dance

The title of the dance performance was Plantulary. The theme, botanical. On a whim, my partner suggested we attend a performance of a new dance work by a small immersive arts collaborative, Aniccha Arts. Through the arc of a single year—from growth through to dormancy—the dancers describe the story of plant life using percussive dance rhythms, music, literary, and various vegetable props. For me, this dance performance was a challenge to appreciate; it was no Swan Lake. I didn’t fully understand the connection between many of the sound and dance elements. But, curiously, the memory of it has stuck with me for the past few days. To set the scene, the stage consisted of a simple dark room lit by spotlights and early evening sunlight coming in through large windows. Along the baseboard of the stage were narrow trays of green seedlings lit by fluorescent grow-lights, forming the outer limit of the performance space. To further imbue the stage with plant life, several moss balls (kokedama-l...
