Trimming back the biomass as part of pest control

Perhaps for the final time this season I was able to cycle to the GH. The temps were in the low 60sF, with a bit of a wind from the west (the ride home was a chore!).

I was introduced to A..., the new Conservatory Service Coordinator. He's seems very pleasant, knowledgeable, and conscientious. He was happy to give me very specific instructions for tending the vines in room 2C and 3C, and then he let me see to the tasks without too much standing over my shoulder.

Coordinator A had me trim most of the vines in order to reduce the overall biomass in room 2C. He and Curator J determined the pest problems could be somewhat mitigated by reducing the overall biomass pressure, particularly in room 2C where the plants seem to grow continuously through the year without much of a dormancy. 

The vines in 2C that I cut back were: Dioscorea bulbifera (the yam family), Chondrodendron tomentosum, Stephanotis floribundia, Euphorbia heterophylla, Passiflora citrina, Thunbergia mysorensis, Thunbergia grandiflora, Paullinia cupana.

Here are photos of the two vine benches in 2C

I also trimmed back the black pepper plant, Piper nigrum (black peppercorn plant). And another plant on the same bench, Ruellia devosiana (Brazilian wild petunia). Photos here:


One of the many striking plants seen today was this Phragmipedium hybrid (primary P. besseae x ?). It is an orchid native to the Andes mountains in South America.

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...
