I need a steep learning curve, always have, always will. If
you want me to stay interested in something, you have to keep my attention,
once I know all the rules and the shortcuts and have learned all the
information, if there still isn’t learning involved, my focus starts to wander.
This has always been the way I operate. When I was a kid, I had crazes. I’d
totally immerse myself in something, and then 6 months later I’d be off that
topic and onto the next. Some people like it when the master a subject, but me,
I just get bored. It’s one of the reasons plants, gardening and the natural
world continues to hold my interest. I’m always learning something new.
Just last week we had an amazing speaker at Murders who
really made me think about bugs in a new way. I’ve never been especially
freaked out by bugs; I actually think some of them are quite beautiful; but I
do find some of them quite irritating, especially when they are eating my
roses, but I’ve learned to tolerate a certain level of them, thanks to a talk I
went to a bunch of years ago given by Doug Tallamy, a Professor of Entomology within
the University of Delaware’s College of Agriculture & Natural Resources. He
made me realize that without insects, there would be nothing for birds to feed their
babies, and with that one fact changed my whole perspective on the way I
battled bugs. I gave up chemical pesticides and switched to more organic
treatments like neem oil, horticultural oil and insecticidal soap; treatments
that worked by smothering soft bodied insects, not by coating them and the
plants around them with toxic chemicals; and I started accepting more insects
in my world. The fact that I was trying to raise bees also helped point me in
this direction. I can honestly say that I was trying to create a more balanced
ecosystem.
Unfortunately I was failing. Or so Jessica Walliser helped
me figure out in the gentlest and most supportive way possible. Jessica was at
Marders talking about her newest book, Attracting Beneficial Bugs To Your
Garden, and although I invited a whole bunch of people, for some reason people
weren’t as excited about learning about creepy crawlies as I was. What a
mistake on their part. First of all the first thing that left me thunderstruck
was an observation so obvious, I can’t believe it had never occurred to me
before. Naturally, like everyone on the planet, I know ladybugs eat aphids and
so are good for the garden. Also I am super proud of the fact that I could
identify a lady bug in its larval form, but somehow, in all the years that I’ve
been gardening with “less toxic” treatments, it never occurred to me that both
ladybugs in larval form and ladybug eggs are both soft bodied and therefore
would be smothered and killed by these “less toxic” treatments. Whoops! How did
I not realize this?
I had been tripped up by the thinking that something that
was organic or natural would be less dangerous. I should know better. I warn
people that although you can use copper to treat black spot on roses, it’s
still a heavy metal and as such can be toxic if used in excess. Nicotine is not only addictive; it’s
also a neurotoxin, not just for insects, but also for most mammals, including
humans. This is why even though it’s a natural ingredient; it’s no longer used
as an insecticide.
The second whammy of the day was the revelatory thought that
since there was really nothing I could do to “fight” the bad bugs in my garden
that wouldn’t also hurt the good bugs, I had the switch directions entirely,
and instead of fighting insects, I had to encourage them. It sounds crazy
doesn’t it, but stay with me. Jessica’s message was simple. Nature has already
created predators for most of the bugs we’re battling, so the best thing we can
do in our garden is to try to encourage them to not just drop by, but to come over
and stay for a while. And for that we needed to know exactly what makes a
garden attractive to the sorts of insects we need more of in our lives.
These two thoughts have opened up a whole new arena of
thought for me, and two entirely new subjects I now need to learn all about. The first is insects. Like I said,
insects don’t freak me out, but I wasn’t really drawn to them in the same way I
was fascinated by plants. I just used to tell people that I didn’t really know
that much about insects because I was a horticulturist, and that to find out
about the bug they had trapped in their baggie they’d need an entomologist. Now
I’m realizing that I really need to know my bugs better; that it’s not good
enough to just know what’s a beetle and what’s a fly, I need to be able to tell
a Minute Pirate Bug from an Assassin Bug and a Syrphid Fly from a Robber Fly.
And that I need to learn how to attract these bugs to not just visit my garden,
but to live and bred and reproduce their since it’s sometimes the larvae that
are the predators of the bugs I need to battle, not just the adults.
I’ve embraced planting to attract birds; I can spew forth
the best ingredients for a hummingbird garden in a sentence or two. I know all
sorts of ways to make butterflies happier. I’ve even embraced pollinator
gardening, (this happens when you start raising bees and you’re trying to give
them as many food sources as possible. Now I need to learn a whole new set of
plant and critter interactions. I know what the deer love to eat, but what
about parasitic wasps? They like coreopsis, goldenrod, angelica, boneset and
veronicastrum; all plants I already have; but also mountain mint and yarrow,
two plants I hadn’t really been desperate to include before that are now on my
“have to have” list. The larvae of syrphid flies eat thrips. I loathe thrips.
They disfigure my dahlias every year, are wrecking havoc on my hydrangeas and
are super hard to deal with since they tend to hide in flower buds – so even if
I was still trying to kill them with an insecticide, it’s difficult to do
so. However, if I add more
calamintha, oregano, dill and cilantro to the asters and angelica I already
have in abundance, I’m creating a fabulous an attractive garden for a nice
syrphid mother to make into a baby palace of her very own. And those Zizia
plants that I’ve been thinking are a nuisance; well perhaps I should encourage
those, as a whole slew of beneficials think they’re the most delicious things
on the planet (a nifty and generous early source of nectar.)
As I’ve said this is an entirely new way for me to think
about my garden, and I’m just starting to incorporate these thoughts, by
intermingling these plants into my existing beds and garden areas, but if I get
really ambitious I can create a beneficial insect garden. It’s probably going
to take me a while to get there, since I have a whole bunch of learning ahead
of me, but frankly I find the prospect of needing to study and do research on
something almost as exciting as the thought of finally making a dent in my
current thrip explosion.

in the year and it’s sort of freaking her out.
