Short and Sweet -- Plant Growth Regulators are
chemicals that can inhibit the growth of plants so they look nice and chubby
on the sales bench at Garden Centers. Some control height, some
control branching, some control bloom time and some control other things
but we're primarily discussing those here that keep plants short and
tight.
Well, looking good and tight and chubby
doesn't sound so bad. Is it?
Yup, it sure is. These chemicals
(like Alar that was pulled off the market for use on food crops because
it showed up in the Apples our children were eating!) can remain in the
plants for years and years and often the plants don't grow properly.
Many are not good for the environment. I've never known a pair of
scissors that hurt the environment! It's easy to over-apply or apply
the wrong product (there are hundreds to choose from) -- see link
below for the problems that can result.
Pruning/cutting plants back with pruners
and scissors, the way we do it, is slow, time consuming, and occasionally
leaves plants looking a bit scalped and/or naked BUT it's the healthy, right way
to grow plants. They grow back tighter and compact but their
overall ultimate size and growth habit hasn't been altered the way it
can be with Plant Growth Regulators. It may mean, especially in
summer, that our plants have been cut back -- possibly very hard. If
your plants arrive that way, embrace them -- they're living proof the
plant has been cut back in a way that assures it's long term health and
growth! Not sprayed with some chemical!
I'm sure there are probably acceptable
PGR's if used properly. Surely there must be because they are used
Industry Wide. It is the rare grower that doesn't use them
(so folks have come to expect tight little stocky plants and often
find ours 'leggy') but when you look at this page from UNC and look at
the problems that can result from their use or misuse, you're not going
to talk us into to even considering their use purely for keeping plant
compact! We're happy with
our scissors and pruners and letting plants bloom when they want even if
it's earlier in the greenhouse and the customer doesn't get to see them
this year. And our plants are happy about this too!

You can pretty much assume that unless
you're buying from a Nursery that grows and sells it's own plants (not a
Garden Center -- please differentiate - Garden Centers just sell plants)
, that you're getting plants sprayed with PGR's. And there are
very few of us anymore -- true Nurseries that grow and sell their own plants
direct to the public! Mass producing is just easier and cheaper,
so there are businesses that just do that and businesses that just sell
them. Very few of us old timers that grow the healthy,
old-fashioned way and then sell those plants direct to you.
"The use of PGR's in modern horticulture is
well established. Indeed certain fields of horticulture such as asexual
propagation are heavily dependent on the use of synthetic PGR's. However
"chemicals" and chemical use are being received less favorably by the
consuming public, particularly if these "chemicals" were used to
produce, or are present, on a commodity they plan to consume!"
International Society for Horticulture
Why have I never heard of Plant Growth
Regulators before?
I was surprised to even read the above quote
in print! ("being
received less favorably by the consuming public")
Think about who is
actually going to know and complain about this:
1. Not the
companies producing the chemicals
2. Not the
growers using the chemicals
3. Not the
public as a whole because they don't even know about them!
4. That
leaves food consumers -- and, even then, a small percentage of those
people who are into Organic Food and/or at least into healthy food without
chemicals. If it weren't for them (and of course, now us on this
page) you
wouldn't know anything about PGR's! There ARE groups
concerned about PGR's sprayed on FOOD crops. But how about
non-food crops?
I can't find anyone with a quick Google
search who seems to be concerned about having them sprayed on non-edible
plants but WE are and just aren't going to use them. If for no
other reason than potential environmental impact. We don't
want them leaching into the creek behind our greenhouses and into the
water table where are well water comes from! We're not going to
eat the trees in our greenhouses, of course, but we are going to drink our
well water and we want the creek water down stream from us to be
un-contaminated. Your child may be playing in it! Your
dog may be drinking it! Ours sure do!
To our knowledge, there is no
benefit to the plant in using PGR's to reduce height and promote
branching. So we're sticking with scissors and pruners!
We hope when you get a plant that looks a little naked or a little
awkward in shape from pruning or clearly even just 'pruned' back
that you appreciate our decision to grow old-fashioned, healthy plants
and control height and promote bushiness with scissors and pruners and
not PGR's.
AND ALSO... Early in the season, if a plant looks
leggy to you (like some Geraniums and other plants do) just like a new
born colt -- that doesn't mean it's weak -- leggy and weak aren't
synonymous -- it's just a normal growth
phase in the life of a healthy living thing!
