Bromeliad and vine maintenance

The beginning of the day was typical for November -- windy, with overcast fast-moving clouds. But, by the afternoon the sun was out, the wind was calming, and the temps were in the mid-50s. It was nice to walk back to my car in the parking lot across campus from the greenhouse.

My first task was to use some of the new hardware J... had purchased to use as support for the vine plants. Specifically I used one of the new carabiner hooks to replace and open hook holding up one of the vines in room C3. I only took a few minutes. It is good to know the new hardware should last them a year or two of vine maintenance.

Coordinator A... then asked me to hard-prune 4 of the vine plants in room C2. They were a bit overgrown, leggy, and infested with scale insects. The infestation was especially heavy at the top of the plants, near the overhead support cable. I took down all 4 of the vines, cutting them back to naked stems 6 inches above the soil. I cut across the stems about an inch above a node, where new stems and leaves will eventually sprout. Fingers crossed! I also removed any dead leaves and other humus from the surface of the soil that might harbor insect eggs and other pathogens. I had been careful to use alcohol spray to clean the cutting snipper between plants, as requested by greenhouse policy.

Next, in room C3 I trimmed a rambling hydrangea back to the stems, as I had for the vines in C2.

Finally, A... asked me to split and repot two of the Southamerican bromeliad plants in room C2. They have become overgrown, sending runners and pups over the sides of the pots. The roots are quite shallow, typical of bromeliad plants in general. Their roots are mostly for support, typical of epiphytic plants. J... suggested I use a well-draining soil (mix of arid and bark 2:1 ratio). The plant names are: Canistrum triangular (green); Neoregelia oligantha (red)

Another routine spectacular day in the greenhouse

It has been a sincere pleasure for me to volunteer a few hours a week at the University of Minnesota Botanical Conservatory. After many visits over the last few years, exactly none of those days have felt ordinary or repetitive. If there is a routine , it is that the botanic diversity of the collection - with over 3000 species - is displayed in a spectacular way each day. The Conservatory is located on the St. Paul campus, and is free of charge and open to the public during typical weekday hours. For instance, today most of my allotted time was spent in just one of eight rooms, the room that houses the tropical collection. The chores included pruning, re-potting, spraying, sweeping, etc. As I moved through the room, in every direction, there seemed to be a stunning plant pleading to be admired. After the chores were complete, I had the opportunity to go back and photograph some of the beauties that surrounded me while working. Dendrobium tangerinum , Papua New Guinea Dendr...

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...

Remembering my former city garden

This post is more of a journal entry than a public blog post. It is interesting to me, but won't be too interesting to almost any other reader - except perhaps my partner who was there as a co-conspirator. I want to document my thoughts about the past, my backyard garden, and what we put in it. The size of our city lot was not large. At 100 x 50 ft, there was just enough room for the house, a small garage, and back yard. The driveway was shared with our neighbor. The style of the house was standard American Foursquare, built in 1903. We bought the place in the early 1990's and slowly, over the next 25 years, renovated almost every inch the house and garden. A dry stone wall was built, with terrace bed to break up the height of the wall Caladiums and dragon-wing begonias line the steps of the front porch Well-earned sit-down on the front porch after a busy day Front wall terrace with blue phlox, hostas, astilbe, snap dragons, and coral bells.
