Repotting a Heliconia augusta plant

 I cycled to the Greenhouse for the second time this season. The weather was cool (in the 50s F), and a bit drippy, but I didn’t get soaked thank goodness. 

On arrival I met Al... in the greenhouse. She had repotting chores for me to do. There is a small tree (Cotoneaster frigidus) busting out of its plastic pot - 14 inch diameter. However, I couldn’t find a larger pot anywhere in the building. There was one terracotta pot in the store room, but it was stuck inside a larger terra cotta pot. I couldn’t get them separated, and at one point the rim of the larger pot cracked. I let Al know the chore would have to wait until we got a suitable pot. I’m a bit afraid I was too aggressive trying to separate the two pots. *Blush*

There were two smaller plants in the ginger family that needed repotting. The larger of the two was Heliconia augusta (red christmas heliconia). Since the plant was already in the largest plastic pot we had in the greenhouse, Al decided we should simply split it and toss out the excess. The replated roots would then have more room to grow.

The smaller of the two gingers is Elettaria cardamomum (the cardamom plant). It currently doesn't have any flowers or seeds. We also split this plant and discarded the excess (actually, Curator J brought the excess plants to a botany class for use).

The soil bin for #1a was quite low after my repotting efforts, so I decided to mix up another batch. The process is quite involved because a large portion of the mix is coconut coir. The coir is stored in large compress blocks. The blocks must be rehydrated to break them up into fibers. The block triples or quadruples in size as it soaks up water and falls apart. My hands became a bit sore after working with the coir to get it all broken up and rehydrated. I did the rehydrating in the workroom so I could titer the water, and do some of the repotting work while I waited for the coir to hydrate.

The recipe of the 1a mix is: 3 parts coir, 2 parts pumice, 1 part sand.

While the coir continued to hydrate, I had to find a new bag of pumice, located in the basement of the building. And, I had to cart a bucket of sand across the building from a storage room to the store room for the greenhouse where I was preparing the mix.

All said and done, there was a lot of running around the building to get the mix prepared. But, it was worth the effort because now the bin is at least 2/3s full, and will last at least another week.

After leaving the greenhouse I walked over to the student center to figure out how to complete the process to obtain an ID badge for the greenhouse - which I need to allow me entry into the locked doors of the greenhouse. I arrived at the post office desk where such things are managed.  There was a young man and woman sitting at the desk (student workers I assume) who were very helpful. They brought up on their computer the application Director had completed the previous week. The man snapped my photo and a few minutes later an ID card spat out of a machine. I now have an official U of M ID card. Curator J asked me to send images of the card, front and back, to him. He will then arrange for the card readers in the greenhouse to recognize my ID.

I celebrate learning this about cycad plants

I didn't know that the cardboard palm - Zamia furfuracea - is a cycad. It isn't a palm tree (don't judge me, I'm not a botanist). But it also doesn't look like the other more familiar types of cycads with their fluted upright palm-like fronds. I didn't know it is said to be the second most commonly cultivated cycad, after Cycas revoluta . I didn't know this plant is unrelated to the common ZZ plant - Zamioculcas zamifolia - although they have a similar appearance. Before today I didn't know any of these things, but now I am happy to have learned them. From the parking lot I walked to the U of M Conservatory greenhouse in near-zero F weather. Stepping into the tropical spaces was a joy of its own. But being able to learn new information and experience new procedures was a compounding factor. Joy squared. During my 3-hour volunteer shift, my initial task was to clean the parasite critters (mealybugs and scale) from the stems and leaves of the cycad, Zami...

Mobile indoor green wall

Finally, after three years... my plant vines have grown and spread to be green wall that I had hoped for. I'm not sure it would have taken as long if the plants were in a more humid, sunny climate, et cetera. But given our indoor Minnesota location - even with a southwest exposure - the vines have needed that amount of time to climb the six feet from the base to the top rungs of the metal grid supporting them. The result has been worth the effort. And to be honest, I didn't have to wait three years to begin enjoying the green wall. The vines were already attractive when only half way up the trellis. A metal grid is filled with mix of Epipremnum aureum cultivar "Marble Queen", Epipremnum aureum aka golden pothos, and Philodendron Brasil . Architecture of the green wall The initial intent of the project was to grow a green wall, in an apartment, that could be moved around to be able to clean underneath, and also to provide a mobile room divider for our open-plan loft....

Strung out in the greenhouse

The assignment for my four-hour volunteer shift at the University of Minnesota Conservatory greenhouse was clearly listed on a whiteboard, with my name attached. Since most of the tasks involved working with strings of overhead cables or air tubing, much of my shift was spent at the top of a ladder. Vining plants are limited to only a few of the many benches in the greenhouse. Steel cables are strung above the benches to support their growth. Because many plants grow in a small space, part of the challenge is to untangle and separate the vines so that they don't strangle each other. Not many of the vines are blooming at the moment, as it is winter. However, Thunbergia grandiflora is producing a few lovely blue flowers (its tendrils grow clockwise, hence the common name Bengal clockvine). It's a popular houseplant, but it has become an invasive weed in parts of the world, like Australia, especially around waterways. Thunbergia grandiflora; notice small brown scale insects sucki...
