Hot Tips: Orchids

Years ago, when we lived in California, friends gave us a gift of an exquisite  orchid plant, which was bred by a highly regarded specialty nursery and  arrived with a written pedigree as long as your arm.  In no time Her Orchidness checked out her new surroundings, concluded rightly that she had been adopted by peasants, and promptly committed suicide.  We were devastated and vowed  that  hereafter orchids were persona non grata.   And we  kept that vow for over forty years. 

So consider my husband’s surprise recently when, at the supermarket, an orchid waved its lovely flowering stem at him as it rolled merrily by in my cart.  I confess:  The devil made me do it.

The seductress in question is a moth orchid (Phalaenopsis), a variety now widely available, even in supermarkets, and enormously popular because it is free-flowering  and easy to grow.  Mine  flourishes with benign neglect.  And the colors.  Ah, the colors.  Magenta, buttery yellow, chocolate, white,  lime green, and bicolors with blotches and freckles and every which thing.  Who could resist?  Clearly, not I.

And now for the great  tip I read about in a British garden magazine.  For increased flowering, when the blooms fade don’t cut the entire stem; rather, cut the stem just below the lowest flower, about an inch above the next node down.  The plant should then rebloom in a month or two.  Let me know if this works for you.

 

Pest- Alert: Box Tree Caterpillar

I like to think of my garden as one of natural exuberance (though some may see it as reckless abandon), and for 23 years I have avoided plants that favor the tightly sheared and closely managed life of a formal landscape. A plant like Box (Buxus), for example.

Alas, the Fates had a different plan in mind. At a recent meeting of my local garden club, I was the “lucky number” winner of Buxus sempervirens ‘Variegata’ , which was hard pruned to resemble a green and ivory pyramid. Poor thing. Yet, there is hope. Its variegated foliage is handsome and once it grows out the plant may be quite attractive.

So that just leaves a pest and disease issue,  particularly problematic for me, an organic gardener. Garden references list over fifteen different problems affecting Box. Moreover, in the December 2011 issue of ” The Garden”, a publication of the Royal Horticultural Society in England, I read about a new horror: the Box Tree Caterpillar, which can completely defoliate plants, and has already done so on mainland Europe. And just this year, it has been found active in private gardens in the U.K.

After a call to the horticultural gurus at the Cornell Cooperative Extension in Riverhead, New York, I was reassured: the caterpillar is not (yet?) a problem in the US. But as it is  native to East Asia ( China, Japan, Korea ) where many of our current and most damaging  pests originate, we had all best keep a watchful eye. Surely one of the downsides of a global society.

Garden DVD:Shade Garden Superstars

There are a slew of garden DVD’s being produced these days, some good, others not so much. One I consult often —- and you will too if you have an interest in shade gardening in general, or Rhododendrons in particular —- is “Elepidote Hybrids In Central New Jersey”. It’s a winner. 

Despite the title, the time-tested information is useful for the entire Northeast and beyond; the detailed  coverage of beautiful large-leafed, flowering, evergreen Rhododendrons is extensive; and the photography is superb. The only problem is that you will probably want most, if not all of the plants . (And wouldn’t the DVD  be a  perfect  gift for the gardener on your list?).

The DVD  ( fifteen dollars plus postage)  is available from the American Rhododendron Society. To purchase, contact: Walter Przypek, wprzpek@aol.com.

Hot Tips: Great New Plant 2011

While visiting my friend Sharon’s East Hampton garden last summer, I was awed by a marvelous plant aglow with a showy profusion of tubular golden bells. It was Phygelius x rectus ‘Moonraker’, an evergreen subshrub from South Africa.  Phygelius has been featured in a number of British gardens (since 1855) but I didn’t think it was hardy on Long Island (zone 7). Its tag said it was. So we were off to the races.

Phygelius x rectus ‘Moonraker’ is a must-have, even if it doesn’t survive the winter, because it blooms  all summer and into the Fall. And for me, it was disease free — a big plus in an  organic garden.  At the oft-times frigid Chicago Botanic Garden,  Phygelius plants have survived as herbaceous perennials. I’d settle for that, gladly. Furthermore, hybridizers have been busy, so plants are also available with flowers in coppery orange, pink, rose and white. There’s even a new  group of ever-flowering  summer, compact, container plants from a British hybridizer, rated zone 8, called the CandyDropSeries. I have seen pictures. Woo Woo Hubba Hubba. Well worth having  as annuals, and due to cross the pond in the Spring. Look for them too.

Hot Tips: Winter Protection for Roses

Container gardening is very popular but container plants are extremely vulnerable in winter, even if they are hardy when planted in the ground.  One option, of course, is to bring them inside but that is often not convenient or possible.  I have adopted a successful method of protection for my roses in containers; it can also be used for other plants. In December, Garden Centers and such will  be selling evergreen conifer branches for inside holiday decoration. White pine branches work well for outdoor protection. Cover the plants top to bottom with the branches and tie them in. Move the pots together in a group, and that’s it. Unlike other methods (as for example, the use of synthetic cones), conifer branches allow for air circulation, and they look good and smell good. (Check out the photo for the looking part). And, most important, this works.
