Winter hardy cactus beds

My first task of the day was to join B... and Al... as we cleaned the outdoor cactus bed at the front door of the greenhouse. I began by removing and rolling the nylon netting, cleaning out the debris stuck in the netting, then carefully rolling up the netting for storage until next Fall. Under the netting, the bed was covered with long pine needles which protect the small cactus plants and yuccas. Many of the Opuntias (O. macrorhiza and O. fragilis) looked to be in fine shape, having survived the winter well. They looked green and healthy. I read that Opuntia fragilis is native to Minnesota. The task took about 3 hours for the three of us to pick away most of the pine needles from around the cacti, quite delicate, knee-bending, and back-stretching work.

I spent 20 minutes tending to the vine bench. There were several vines that had stolons stretching onto neighboring plants. These had to be removed or pruned to prevent the plants from becoming hopelessly entangled.

Finally, I was able to repot the Cotoneaster frigidus tree which I had intended to do last week. This week, Curator J... had sourced a plastic pot large enough for the root ball. Before potting the plant, I had to clean out the pot with the outdoor garden hose located between the buildings. I removed the old pot from the root ball, really ‘tho most of theold plastic pot shattered as I pulled on the edges. It was quite easy to expose the root ball. Once fully exposed, teased away the root fibers and cut off the lower 2 inches of the root ball. This will allow the new roots to find the

new potting soil.

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.
