Mealybug control = regular patrols
Left: Mealybugs love to imitate lint or dust. Right: They
also favor those tiny niches at leaf axils and stem tips. Hard to
reach them in there!
Below: Mealybug destroyers (Cryptolaemus beetles) are much
like ladybugs. However, their young are not so simple to
pick out from among a mealybug mob. This is a mealybug
destroyer larva. Its appetite for mealybugs is probably even
greater than that of an adult, but its chances of being
mistaken for a mealybug and squashed by a gardener,
Bathe a mealy bug
Above: Trudy starts mealybug cleanup on her kumquat.
Even if this plant can survive temperatures into the teens, that
cold would take its fruit and leaves.
Below: That's a long-tailed mealybug Trudy's after with her
swab. It's one of the three most common greenhouse mealybugs. We
told her to be glad it's this one and not the tailless citrus
mealybug. Citrus mealybug females lay many more eggs.
Just look at these pictures -- what an eye and a focusing power
Steven has. I can see the mealybug in every shot including when
it's scrubbed up and then off the twig.
In the photo below right, Trudy's swab got the older, waxy
mealybug but the younger mealybugs remain on the stem of the fruit.
However, they've now been swabbed with alcohol and at least some
will die as a result. Download the pdf to read more.
A gem outdoors, gerber's a baby in the house
Mildews, stem rots, leaf spots, and botrytis -- a.k.a. gray
mold -- are all fungal infections. (Here, botrytis on an
overwintering Aeonium. If you look sharp you can see the gray fuzz
that explains this infection's common name.) When water sits in
dark, still nooks like the places where these leaves meet stem,
ever-present fungal spores may find all they need to get growing.
If at that time the plant is stressed because the air's overly dry
and low in energy because the light's dim, its cell walls and
internal chemical defenses are weak. The fungus gains ground. Download the

Expert Gardener Afield: Report from a national nursery's new
Below: You mentioned that you were explaining to a reader
recently how there are several plants all called Joe Pye so she
shouldn't think hers was mislabeled just because it wasn't the
same as one you showed. How about this Joe Pye?! How's that for a
different look? - Cheryl Bennerup, Sunny Border Nursery
Eupatorium 'Frosted Elegance' (above) and Trollius 'Cheddar'
(left,below) are perennials. This Torenia 'Yellow Moon'
(center) and Osteospermum 'Zion Copper Amethyst' (right) are
"temperennial" -- hardy somewhere but not for us;
candidates for indoor overwintering. Photos courtesy of Sunny
You call this winter fun -- whining and dying?
Above: I loved this banana while it was in the garden. In a
living room, its kind don't appeal to me.
Below: Now, the banana Cheryl Bennerup showed me (bottom,
right: Musa 'Siam Ruby') I might love that anywhere, even listening
to it whine all winter! Photo courtesy of Sunny Border
Below: At another of the great nurseries of our time,
Glasshouse Works in Stewart, Ohio (glasshouseworks.com), no one's
fussing over-much about overwintered plants. They're set out en
mass on a barely heated glassed-in porch and left to keep each
other company. Download the pdf to read more.
Notice trees that need pruning.
We went out to admire hoar frost (left) on our red
horsechestnut's twigs and saw this 2" branch (right). It's rubbing
in two places (yellow arrows), which damages the wood and leaves it
open to infection and insect attack. It's also growing at such a
narrow angle from its point of origin that it's bound to break one
day from the weight of snow, ice or even rain. Then it would rip
away, ruining both limbs. So during the next thaw I'll cut it off
clean at the blue lines.
