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.

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
