Fungus among us

In Room D2 Director A... had me look at a fungus matt located on one of the low bushes (?name). She had been reading about parasitic fungus from Australia/New Caledonia and wondered if perhaps this particular plant’s fungus might be an example. I asked her for a couple of glass slides with which I took a scraping of the fungus. We took the slides into the plant pathology lab and used a microscope to view the slide. We saw what looked to me to be standard dimorphic fungus with yeast forms and septate hyphae. There were branches at 45 degree angles, and fusiform conidia. I suspect this is a common fungus, perhaps Aspergillus sp. We also saw a small 6 legged insect/mite.

In Room D2 (“Dwight’s room” as A... calls it) I trimmed a tree palm (species?) branch, and then scrubbed sooty mold off from a fig tree that had been hidden by the tree palm branch.

In Room C3 I repotted a large ZZ plant from an old white plastic pot to a new large terracotta pot (not the largest pot tho). I used a 50:50 mix of bark and arid mix (as recommended by B...)

I also repotted a small yucca tree from a plastic pot into one of the largest terracotta pots. The soil had to be teased off the roots and replaced with an arid mix (no bark). Curator J... asked me to saw off the root ball at the bottom to stimulate fresh root growth.

Three different groups of high school students toured the greenhouse while I was there. The greenhouse staff acted as tour guides.

Rebuilding the support for vanilla vines

Raining in February   The morning began with a walk in the rain from my car to the Conservatory greenhouses - in the month of February. According to the calendar, we should be in the depths of winter. The precipitation today should be snow not rain. The storm system that we're experiencing is probably related to drenching rains moving inland from the west coast. I met Coordinator A... at the door of the Conservatory. His office desk faces one of the main doors to the building. He cannot escape observing everyone who enters...poor guy, it must be distracting for him. Anyway, as soon as I entered the building we started to discuss his plan for my activity of the morning. He offered me the project of rebuilding the support for vanilla vines which have been suffering from overexposure to sunlight and dry air. A bit of background The vanilla plant (Vanilla planifolia) is in the orchid family. It is native to Central America and Mexico. The seed pods were used by the Aztecs to flavor coc

Frankincense and Myrtle: Fragrant Treasures

If you were raised in the Christian religion, you've probably heard of frankincense and myrrh. But, do you know much about them, beyond being fragrant commodities as precious as gold? Until today, I could not have described frankincense, myrrh, or citronella. But, by the time I was finished with my volunteer shift at the U of M Conservatory greenhouse I knew more about them. However, I will have to wait for another time to actually see a myrrh tree. I'm not sure if the Conservatory has a myrrh tree. I do know myrrh is in the Burseraceae family, the same family as the frankincense tree. They are not in the myrtle family as the name would suggest. The myrtles (or Myrtaceae) are the gum trees of the Australasia, one which gives us citronella (see below). Maintenance of small trees The day's duties assigned to me were to provide general light maintenance to a group of small trees located in the desert and subtropical rooms of the greenhouse. Maintenance included pruning and mak

Infection control in the Conservatory, from mundane to amazing

Volunteering at the University of Minnesota's Conservatory Greenhouse As mentioned in prior blog posts, for the past three years I've been volunteering for a few hours a week at the Conservatory greenhouse at the St. Paul campus of the U of M.  This blog is about activities there, and the many fascinating and beautiful plants in the collection. A little background about plant infections Everyone who has cared for a plant, from houseplant lovers to professional nurserymen, has learned the hard lesson that plant pests and diseases are an inescapable fact of life. All plants, domestic or wild, are susceptible to the infectious agents and parasites. Plants in their native habitats are largely protected by the ecosystems surrounding them, where pests do not have the luxury unfettered consumption. Plants grown indoors have been removed from their ecosystem and they are sitting ducks for parasites to proliferate unchecked.  Indoor gardens rely entirely on pest control methods with var
