Cymbidium for Christmas

Today, a few days before Christmas, the weather turned very cold. The high today is expected to be -6F. Like other fool-hardy Minnesotans I ventured out to the greenhouse to fulfill my appointed duties. However, when I arrived there, only Curator J.. was in the building. He asked if I would stay and do a bit of sweeping, which I did for about two hours. There wasn’t a lot of debris under the benches, but every bench had a little bit. So the benches in all four collection rooms needed attention. I also swept the workroom.

I have to state the floors of the greenhouse look much tidier since J’s arrival, thanks in part to a leaf blower recently introduced to the greenhouse. He has made a significant effort to get pots up off of the floors onto low benches. The floors clearly are being washed more frequently compared to before his arrival. It is important for the greenhouse because it reduces the biomass on the floor for the proliferation of pests and fungus, which then spread to the plants in the collection, particularly if their pot is sitting directly on the floor.

Next week, I’ll contact A...to ensure there is enough for me to do on the 29th.

A plant that was particularly beautiful today was a cymbidium orchid in full bloom. The plant was approximately 4 feet in diameter and height. There were several flower spikes, each bearing half-dozen open blossoms, and as many buds. The blossoms were each 2 inches in size, with pale green petals bearing reddish-brown spots. The blossoms were not particularly showy, blending into the background foliage. But they were perfectly formed on closer inspection. Gorgeous!

Thrip control: peppermint and clove

Here's a question: how many natural plant scents do you find repellent? The one that comes to the top of my mind is the scent of the newly blossomed corpse flower, Amorphophallus titanum . It smells very much like the name implies. If I could produce a scratch-and-sniff blog post, I would be tempted. The odor is horrible to humans, but sweet to some flying insects which are also attracted to rotting flesh. But perhaps you cannot tolerate the scent of clove, or eucalyptus? Insect pests are like us in this respect. Pests in the garden and greenhouse Insects, arachnids, fungi, and viruses. Their numbers are legion. The battle is constant. The most effective weapon is vigilance. In addition to vigilance, there are biological controls made from natural compounds which are generally non-toxic to humans. Included in this category are essential oils. For example cinnamon, rosemary, sage, neem, clove, peppermint and many others. These oils are repellent, and even toxic, to many of the pests...

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.

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...
