Water lily maintenance

Before arriving for this weeks activites in the greenhouse, I was informed some of the staff had been exposed to covid, and were home in quarantine. Curator J... had issued an email earlier in the week, which outlined the current guidelines regarding covid.

My first task was to empty a large bathtub-size tank. It contained a few water lilies which failed to grow well. They remained too small to be adequate examples of their species. The tank also features a small floating fern. A asked me to save the fern into a glass jar, along with the tank’s bubble tube. The lilies were discarded.

I emptied the tank and washed the sides of the adhering algal growth, rinsed the tank, and left it on its side to dry.

I repotted a couple of small hibiscus plants native to Kauai (Hibiscus clayi), Hawaii (family Malvaceae). They were placed in new plastic “azalea” pots with relatively shallow depth (5 inches or so). A asked for soil 1a. She also asked us to desist from using paper towels in the bottom of pots because they stayed too wet.

Finally, I walked through the display rooms picking up leaves and pruning leaves off plants.

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.

Nerding out in Japan, autumn of 2025

We celebrated a bit of good news in our household with a spontaneously planned trip to Japan in November. Completely unintended, the trip coincided with the full regalia of fall colors. Particularly notable were the popular Japanese maples of every size and variety with their brilliant reds, yellow, oranges, greens, and rusts. But happy accident, we learned a few things about the art of sculpting full-grown trees - niwaki - and how to protect plants from ice and snow over the winter - yukizuri . Winter is coming The fall colors were still in full swing with crowds of adoring leaf-peepers - like me - filling the famous gardens and parks. Despite the crowds, there was already serious preparations for the coming winter. Fancifully pruned trees - the tree-sculpting art of niwaki similar to bonsai - were being trussed with ropes and propped up on long poles . As newcomers, the preparations seemed extremely odd, as if some hurricane was about to shred the life out of every branch an...
