Deep Cleaning in the Greenhouse

When cleaning my home or work space doing the drains is the dirtiest chore on the list. Almost all of the dirt and grime funnels down through the drain. If the drain is clogged, civilization as we know it, stops.

Today my task was to clean window sills and ...drains. The University of Minnesota Conservatory Greenhouse, where I've been volunteering, continues its summer push to deep clean the surfaces and plants to help keep them free of pests and diseases.

Integral to a thorough job of cleaning includes lifting the drain grates and flushing out the accumulated soil and organic muck (dead leaves, seeds, etc.). Hiding out of sight under the grates, the muck is potentially a fertile reservoir of pest eggs and bacteria.

There were approximately a dozen drains in the four greenhouses of the Conservatory. Each drain consists of a heavy cast cast-iron basket covered by a round iron grill. I lifted, brushed, and washed each component.

While I was working from drain to drain, I spotted this blooming Burbidgea (golden ginger bush), native to the island of Borneo.

There are over 30,000 species of orchids in the world, the most abundant of any other type of plant. There are so many orchids in the collection that there are always beautiful blossoms to admire. Today, I found a lovely vanda orchid hanging is its basket. Vanda orchids are a large genus, with 90 species. They are native to Southeast Asia.

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...

Autumn Inside the Greenhouse

I felt the firm grip of fall as I walked the half-mile from the parking lot to the Conservatory Greenhouse at the University of Minnesota, where I volunteer. The temperature outside was in the 30s, and the wind whipped at my face. Yesterday there had been snow flurries. In stark contrast to the outside world, the greenhouse climate was quite different. Part of the greenhouse is maintained at near-tropical temperatures. But other sections of the greenhouse are kept significantly cooler to support plants that have evolved in seasonal climates. Although indoors, autumn has arrived here too. The sunlight dims, and the nights grow long. Inside these cool greenhouse rooms the plants shed their leaves and virtually cease growth for the winter months, just as they would outdoors. Part of my assignment for today included the pruning of yellowing and brown leaves. Removing the dead foliage from the plants and the floors helps to reduce the overall risk of mold and other pests affectin...

Bog Monsters

As a layman of botany the idea of carnivorous plants has perplexed me. The capturing and eating of other creatures seems like it ought to be limited to animals, since animals are mobile and plants are not. Almost all plants survive and thrive in the world through photosynthesis. They do not need to feed on animals to survive. But, what about the group of plants that are carnivorous? As stationary plants, why and how do they eat critters? This topic was stimulated by my assignment today at the Conservatory Greenhouse of the University of Minnesota. My task was to clean several large tanks of water filled with aquatic plants. While cleaning the tanks I realized many of the plants were classified as carnivorous . What is it about the aquatic environment that causes plants to eat - in effect - other creatures? The short answer is carnivorous plants evolved in nutrient-poor settings such as pond water which is naturally low in the amount of nitrogen needed to synthesize proteins. To compens...
