REVIEW FOR 2015
Dr. Leonard Perry, Horticulture Professor
University of Vermont
At the end of the year and another gardening season, make notes (before they
become distant memories) of this past year’s successes and failures.
As you reflect on this past year and plan for next year’s gardens and
landscaping, review some of these topics from our 60 Green Mountain Gardener
articles during 2015. These included ones on plants, from perennials and
annuals to food crops and indoor plants; animal pests; food preservation;
pollinators; and more.
Deer are a problem for many gardeners, with tips on choosing deer resistant
plants the focus of one article. Facts were given on plant traits that
attract, and discourage deer, and reasons why deer eat some plants and not
others—why there is really no deer-proof plant, just resistant ones.
If you have a deer population nearby, you might choose to not plant yews,
euonymus (burning bush), hybrid tea roses, and saucer magnolia for woody
plants. For perennials, avoid planting (or protect) crocus, dahlias,
daylilies, hostas, impatiens, phlox, and particularly lilies and tulips.
An article on hellebores, or Lenten rose, focused on this popular, early
spring flower that only reaches a foot or so high. Leaves are divided
into leathery leaflets with coarsely cut, or spiny, margins. The
nodding flowers, up to two inches across, are generally in shades of white,
rose, green or purple. Some new hybrids have spotted flowers, others
are quite double or bicolors or streaked.
Spiderworts are a more attractive perennial than their name suggests.
They flower in early summer, in a range of colors depending on cultivar
(cultivated variety). With proper choices, and a little care—the
subject of that article—you can have plants free of disease and that don’t
An article was posted in late summer on a perennial flowering then—Joe
Pye. This name doesn’t do justice to this hardy perennial, which has
gorgeous blooms over a six-week period or longer, and is low
maintenance. Most species are native wildflowers of the eastern United
States, good for pollinators. There are Joe Pye selections from under
two feet tall for small spaces —such as ‘Little Joe’ or ‘Phantom’, to over 6
feet tall for backs of borders—such as ‘Carin’ or ‘Early Riser’.
One lawn care article covered how to grow them successfully using less
nitrogen—beneficial for the environment and costing less money.
Another covered some common lawn pests and their controls. Realize
that lawns are teeming with insects, most either beneficial (eating the bad
insects), or causing no harm. The few bad insects get all the
attention and, by trying to control all insects, you may be killing helpful
ones and many innocent bystanders. The bottom line: you don’t
want an insect-free lawn.
If you have a lawn, have you ever considered shrinking it? You can
still have a lawn for recreation and beauty, perhaps just less of it.
In an article on this topic, design tips and groundcover choices were
Other plant articles from 2015 included ones on birch trees, begonias,
Solomon’s seal, gaillardia, coleus, and fall asters. Houseplant topics
focused on succulents, terrariums, forcing bulbs, dracaena, and proper
watering. Environmental gardening topics included pollinator plants
and wildlife trees (“snags”). Articles on growing edible plants
covered pruning apple trees, asparagus, preventing bird damage to fruits,
and preserving tomatoes.
There were several health articles in 2015, including ones on spring
training, proper lifting, horticultural health—staying healthy during the
gardening season, accessible gardening, and tips to reduce garden
allergies. Particularly this winter, check out and regularly practice
the easy training tips so that your body is in shape when the next garden
These articles, and more on many other gardening topics, can be found online
(perrysperennials.info under the Home Gardener section) and searched by
season or by topic. Combine these with your own notes, and you should
have new plants to try, a healthier body, a more sustainable landscape, and
more gardening successes in this coming year.
