A Field Trip in the City


“New England Grows,” an annual green industry trade show, took place this week in Boston. Landscapers, garden designers, nursery owners, arborists, groundskeepers, teachers, and other garden professionals come to this event to see the plants and equipment that will help them do their best work in the coming year. The show includes a series of lectures and demonstrations, too.

 

Liz and I had a chance to visit the show yesterday. It was a cold, windy walk from our office to the Convention Center, marked by a few wrong turns. But the sight I saw when we finally got there warmed me right up. (With help from the hot chocolate we managed to hunt down.) The front lobby looks down on the main exhibition floor, which, being covered with garden supply exhibits looked much like spring.

 

Besides admiring the exhibits of plants, pots, and tools, we sat in on a pest-management lecture given by Leanne Pundt of the University of Connecticut. The talk was geared toward industry people (naturally, that being the audience), who are trying to fight pests and diseases on a large scale. But I did pick up some tips to use in my own garden:


  1. Learn the cultural requirements of my plants and meet them as best I can. Healthy plants are more able to fight pests and diseases.

  2. “Scout” my garden regularly. Look for symptoms on plants, the pests themselves, and the activity of pests’ natural enemies. Inspect new plants as I get them.

  3. Choose native plants, which are more likely to attract beneficial insects and the pests’ natural enemies.

From the slides I recognized that last summer some of my columbines (Aquilegia) had columbine leafminers. The columbines were some of my favorites of what I planted last spring. I have Aquilegia canadensis ‘Little Lanterns’, A. alpine ‘Alpine Blue’, and A. vulgaris plena ‘Rose Barlow’. I will follow Leanne’s advice to be sure to choose native columbines. (Of the three that I have so far, only A. canadensis is native, and I do think it was not affected by the miners, though I’m just going by memory. I have to keep better notes!)

I am sorry to say, but A. canadensis is not immune to leafminer. I have A. canadensis in abundance growing wild. I have one plant (a volunteer) growing in the edge of a path next to the driveway (unpaved) where the only care it receives is the occassional removal of encroaching weeds. It is robust with the flowers rising up to two feet high. Its leaves become veined with leafminers every year to no detrement of the plant.

On the other hand, I have occassionaly transplanted one in my garden. They seem to do best nestled up against other plants where they happily co-exist and their proximity does not bother the other plant one bit. These A. canadesis do not seem to be bothered by leafminers. I might suggest this might be because they are nestled in a garden bed with other varieties of plants around them.
