Re: [GSAS-Member] Pond Algae is a hairy problem

Thanks Cliff and Betty,

I agree plants would definitely be a good direction.  Right now the pond
is about 1/3 covered with Water Hyacinth, water lettuce, lillies, frog
bit and duckweed. There are numerous other plants in the pond as well,
but, not ones that cover the surface.  The pond gets sun all day, full
sun.  I agree chemicals are not desirable either.  Do either of you know
where one might get inexpensive plants for the pond?  I think the
surface needs to be more covered than it is.

My in-laws have a rather large (acre+) pond on their property, and have
dealt with similar issues as long as they've owned the lot.

You can attack the algae (which I think is what the straw does by
hosting bacteria incompatible with it) with additives, or short it of
resources (usually with lots and lots of vascular plants).

What kind of plants are currently in the pond, how full of plants is it,
and is it in full sun?  If it's getting a lot of light, you'll likely to
'enjoy' the algae fight almost every year.  I'd try to find someone with
some nice wild water lilies.  The cultivated kinds are probably showier,
but they tend to go for $20+ each...the wild ones in my experience have
been much hardier and are still plenty pretty--  I knew several people
on the east coast that had to compost heaps of them every year just to
keep some fishing area open in their farm ponds.  If it's getting more
than a few hours of direct sun every day I'd probably try to cover
25-50% of the surface...

In a very small pond (like my 200gal garden pond), a similar effect can
be obtained with frogbit (which is what I use), water lettuce, water
hyacinth (also pretty when blooming and a great nutrient sponge),
etc...but you have to skim those off for compost much more often than
the lilies.  Once some of the light has been blocked out, adding more
oxygenating plants to the water column to help drain the nutrients and
should slow the algae down quite a bit.  I prefer "highly invasive"
since I don't have the greenest thumb...parrots feather, elodea,
hornwort, etc...but once added to a pond of any significant size,
they're eternal...and of course should be kept well away from other
local water sources.

The other route is to buy lots of chemicals every year and spending the
time to make the pond look more like a pool (which is probably the
desired result in many yards and gardens).  Your local nursery might
prefer this option, but I find the time, money, and energy really isn't
as well spent as finding more ways to enjoy the algae.  =)  It's
surprising how the balance of power will often shift in a few weeks of
neglect, and then the plants will have the upper hand again...
