Plant Answer Line Question

Keywords: Ferns, Matteuccia

I have ostrich [deciduous] ferns [on the grounds I keep] and I was wondering if there is anything special that I should do for them for the winter. What I have been doing is putting ground up leaves in the bed, but beyond that, I'm not sure if there is anything else I should do.

Answer:

Andrew MacHugh's book, The Cultivation of Ferns (1992) says the following (from p. 47):

"In autumn, a mulch of well-rotted leafmould, peat or bark chippings should be given to ferns planted in open sites. [...] In winter the fronds of deciduous ferns can be cut back to an inch above the crown. In areas subject to frost, the decayed fronds will provide some protection to the plant and should not be removed until the spring growth of new fronds shows signs of emerging."

Plant Answer Line Question

Keywords: Ferns, Pteridium aquilinum, Perennials--Care and maintenance

My question has to do with the fall/winter foliage of bracken fern (Pteridium aquilinum). A friend trimmed the bracken to the ground. Will the bracken grow back next spring? This led to other questions. Does bracken lose only its leaves in the winter or does the entire plant die off? Does it spread through its roots or spores? Any information you have would be appreciated.

Answer:

Bracken is deciduous, that is, the fronds die to the ground in winter and then regrow from the rhizomes in the spring. If your friend cut her bracken down to the ground late in the year there would be no problem. Even if it was earlier in the year, the bracken would probably survive. According to the fern books I read, people have tried mowing to remove their bracken with no success. The books also warn that bracken is very invasive and not recommended for small gardens. It spreads by underground rhizomes, maybe by spores as well, and can take over a large space in a very short time.

It might be a good idea to take a look at some pictures either in books or online (just enter the name in Google and select Images above the search box) to make sure this is what your friend has. Any deciduous fern (and even some evergreen ferns) can be cut to the ground in fall, but generally it is better to wait until the new fronds appear in spring to cut out the old fronds of evergreen ferns.

The USDA Plants Database provides further information.

Plant Answer Line Question

Keywords: Ferns, Dryopteris, Pruning

My wood ferns (now about 4 feet in diameter)have fronds which are now partially brown. Can I prune all the 'old' fronds off and let the new ones take over without damaging the plant? When should I do this?

Answer:

Sources are divided on when and whether to prune wood ferns (Dryopteris). Some consider Dryopteris "self-cleaning," meaning that the old fronds will eventually disintegrate on their own (Gardening with Woodland Plants by Karan Junker; Timber Press, 2007). If you are inclined to tidy up the look of your plants, they can be pruned of their old fronds after new growth begins in the spring (be careful not to cut the new fronds), or according to other sources, in late February or early March before new growth starts. Rainyside Gardeners and Great Plant Picks, two Pacific Northwest resources, offer more information. Rainyside advocates pruning once there is new growth, and Great Plant Picks advocates pruning before new growth begins.

Garden Tip

Keywords: Polystichum, Cyrtomium, Blechnum spicant, Plant and garden societies, Polystichum munitum, Ferns

To create a desert oasis look plant a few hardy palms and then add evergreen hardy ferns such as Deer fern (Blechnum spicant),Big leaf holly fern (Cyrtomium macrophyllum), Western Sword fern (Polystichum munitum), and Soft shield fern (Polystichum setiferum). Growing a few ferns usually leads to growing many ferns - there are so many cool species out there. Learn more about the world of pteridology (study of ferns) by joining the locally based Hardy Fern Society. Members receive a packet of fern growing information and a quarterly newsletter; they also participate in a spore exchange and produce the wonderful Fern Festival and plant sale each June. To join the society send $25.00 to The Hardy Fern Foundation, P. O. Box 3797 Federal Way, WA 98063-3797.

The Natural World of Winnie-The Pooh by Kathryn Aalto, 2015

Reviewed by: Brian Thompson on 2016-04-01

I picked up “The Natural World of Winnie-The Pooh”, expecting it to be lightweight and quick to read, but instead I became enchanted and deeply engaged. The author, Kathryn Aalto, is a former Pacific Northwest resident (she taught at Western Washington University and Everett Community College) who now lives in England.

Almost any list of the best English books for children will include “Winnie-the-Pooh” (1926) and “The House at Pooh Corner” (1928) by A. A. Milne. Much of the inspiration for the places in these books comes from real places in the Ashdown Forest, southeast of London, and from the nearby farm where Milne and his family—including his son Christopher Robin—lived.

After setting the stage with a biography of Milne and of the illustrator, E. H. Shepard, author Aalto gives a detailed review of the story elements as they relate to real places. Fortunately, these places have been little changed in 90 years: “There are no overt signs pronouncing your arrival in Pooh Country. There are no bright lights or billboards, no £1 carnival rides, no inflatable Eeyores, Owls, or Roos rising and falling in dramatic flair.”

The last third of the book is essentially a field guide to the Ashdown Forest, including its natural and cultural history. One thing you learn is that despite the name, there are no ash trees, and much of the land is not forested, but it is a place of considerable biodiversity despite much human intervention over many centuries.

Excerpted from the Spring 2016 Arboretum Bulletin.
