Willow Pruning in the Malott Japanese Garden

If you took advantage of the warm weather last Tuesday and decided to visit the Chicago Botanic Garden, you may have noticed something unusual, especially if you wandered over to the Elizabeth Hubert Malott Japanese Garden.

The Zigzag Bridge was closed for public safety until we could finish pruning.

The sight of horticulturists walking on water was not a hallucination.
In spite of the 60-degree weather, the lake was still frozen and we took advantage of the situation to finish some winter pruning.

The arborists, equipped with the proper safety equipment, are busy pruning the small willow branches.

 Though this willow pruning appears very intense, even harsh, it provides airflow into the tree and gives young branches more room to grow. Some of the large, more upright branches are left to provide height. From an aesthetic point of view, this pruning gives the tree significantly more texture, creating clumps that flow into thin weeping branches. As willows can become quite large, pruning also prevents the tree from becoming disproportionately so.

For the past four years, Benjamin Carroll, the senior horticulturist who maintains the Japanese Garden, has been working with arborists from the area to shape up his trees to give them a more traditional appearance. This style first emerged in Japan.

Seba on the Kisokaido by Utagawa Hiroshige shows the style we are trying to emulate.

Before this style of pruning was implemented, the willows were pruned to appear mounded. For the first three years of this pruning style, many large branches were cut to drastically change the appearance of the trees. This past year we were able to focus on smaller branches.

January is the best time for us to do this because the trees are dormant and the sheet of ice on the lake is fairly thick. Tree dormancy is very important when pruning because nutrient flow is minimal and the wounds made by winter pruning will heal quickly in the spring.

Cleanliness is very important to us, it looks good and reduces debris that could promote disease.
While the arborists cut branches with pole saws and chainsaws, I moved branches off the ice.

 The thickness of the ice is also helpful to us because it simplifies cleanup.

After the branches are moved to shore, they’re loaded onto a club car and taken to the mulch pile.

Cleanliness is very important to us because it not only keeps the Garden looking its best but it also reduces debris that could cause disease problems in the future.

Though we look fairly confident walking on the ice, it is important to remember that ice is always dangerous. We always have seasoned professionals and the proper safety equipment nearby.

Reflections on 12.12.12

Two Garden staffers set out to capture 12 hours of the Chicago Botanic Garden on 12-12-2012 to submit to the One Day on Earth project. It turned out to be an ideal day to capture winter beauty with clear skies and lots of wildlife. We saw the lights at the Lake Cook Road entrance while it was still dark, the sunrise over the Malott Japanese Garden, gorgeous morning sun on the display gardens, the indoor Wonderland Express exhibition, the sunset over the Regenstein Fruit & Vegetable Garden, the holiday lights on The Esplanade and the indoor Greenhouses. Wonderland Express is open through Jan. 6, 2013, so don’t miss it!

Snacker, Flapper, Sleeper, Napper

All animals that inhabit this area, including humans, have to cope with the changing of the seasons. There are four basic responses to the cooler temperature and shorter daylight. Which is your favorite strategy for surviving the winter?

Do you eat more food during this time of year, loading up on high calorie goodies? You may be a Snacker. It is a natural instinct. You are like the squirrels, rabbits, and some birds that fatten up and keep going all winter long.

Squirrels fatten up on seeds and stay active all winter long.

Do you travel to warmer climates during the winter? Wings are not required to be a Flapper. Count yourself in the company of warblers, monarch butterflies, and herons if you leave the area in winter. You may be migrating to escape the cold, but these animals are generally traveling to find more plentiful supplies of food.

Do you become sleepy and hibernate for four or five months every year? Then you are a Sleeper, like a bear, turtle, or frog. These animals undergo physical changes that shut down their respiratory systems and metabolism during the winter. You are probably not a true sleeper, even if it sounds appealing.

This bronze turtle can be seen all year at the Kleinman Family Cove, while the real turtles are hibernating in the mud at the bottom of the lake in winter.

If you are prone to feeling tired and sleeping more in the winter, then it’s more likely that you are a Napper. Animals like skunks and opossum cozy up in burrows or under deep piles of leaves and sleep. Occasionally they emerge, find something to eat, and then go back to bed.

Like the skunk, this baby opossum emerged from its nap and is looking for something to eat before it returns to its shelter.

Snacker, Flapper, Sleeper, Napper — try to say that three times fast as you prepare for another midwestern winter!

What’s in Bloom This Winter?

In this video, Boyce Tankersley takes us on a tour of what’s in bloom in the three Greenhouses in the Regenstein Center. We’ll learn about carnivorous plants, a Sago Palm and some giant aloe plants. He also shows us a plant that blooms outdoors even in winter. Visit http://www.chicagobotanic.org/inbloom for more information.
