would a 4"w x 3"h pot be large enough to plant a Nymphaea 'Pygmaea ' in?
<Cam, you can try it and be ready to transplant if the root ball gets
too big. Basically, you have to make sure the roots don't get choked,
just like a plant in the soil.
Read this report on the plant from University of Florida:
By the way, are you aware of the Arizona Aquatic Plant Association? It
was started by Rhonda Wilson, who writes the regular planted tank column
in Tropical Fish Hobbyist Magazine.
The club has a good number of members in both Phoenix and Tucson who are
familiar with keeping plants in our harsh climate, and a very active
Re: Lily Question 9/16/12
would a pot that is 7.5" wide x 5" deep work in a 6 gallon pond that is
16"w x 16"d x 7"h?
<At some point, you just have to bite the bullet and go for it. By the
way, 16x16x7 is almost 8 gallons, not 6. Still awfully small for the
climate. Maybe keep it indoors during summer and take it outside in late
September, using a 25-watt heater in the winter. - Rick>
Worm that is eating my water lily
Many thanks for considering this. My water lily is full of holes and, on
inspection, I saw thin white worms (almost invisible) on both pad
I also noticed them crawling around the edges of the pond close to the
surface of my half-barrel pond. They appear to hide in the gaps between
the boards of the barrel. They crawl surprisingly quickly.
<Mmm, insect larvae of some sort... are there any adults flying about?>
They are up to 1/4 cm in length. On closer inspection they have forked
'tails' that they appear to paddle with. They have dark heads (possibly
red) and a pattern in the same colour on midsection of the upper surface
of their white bodies.
I have attached a couple of photos.
I'm very curious to know what they are and what to do to protect my
water lilies from being destroyed (over 2/3 of the pads have been
<The safest approach is simply to rely on blasting them off early
mornings with garden hose/water... and relying on fishes in your system
to eat them (platies, American Flagfish, smaller goldfish, Koi)... Up
from this are oil (only) sprays like Volck... Search WWM re. Bob Fenner>
|Re: Worm that is eating my water lily
I have found it impossible to identify a curious floating entity on my pond.
They float around the pond edge, at the base of my reed mace and around the
edges of lily pads. They resemble miniature, grey curling leaves.
<Pupae cocoons... after the flies have flown>
On closer inspection they are segmented. When I looked into the pond last
night with a torch I was surprised to find white ones floating on the pond
(or were they reflecting the light? I'll have to check that one out).
<White ones are newer, still have larvae in them>
I have never seen them change. They crumble or break up if touched.
Perhaps they are clusters of eggs? There is nothing I can find online about
these but I have lots of them.
<Same resp. as last time. BobF>
small pond with water lily leaf damage
Hello! I have a 150 gallon pond in Houston area. We have 10 goldfish and
a water lily. There is also a ribbon snake, about 12 inches long. The
water lily leaves are torn apart and separated from the plant. I s this
the work on the ribbon snake?
This happened last year and we lost the lily. Also, last year we had 40
fish so has the snake been feasting? How do I get rid of him and move
him to another pond? Thank you, Fran
<Likely the damage was caused by another predator... a bird, perhaps a
mammal... Read here re all:
and the linked files above. Bob Fenner>
water lily leaves 7/18/2010
Can you please tell me how, ( the process by which), water lily leaves
turn back up the right way after my Koi have turned them upside
<Gosh, I don't know... other than to concur w/ you that they
IF not flipped all the way over. Is it water tension on the
"bottom" surface, and a lack of this on the upper waxy one?
Perhaps a quirk/property of the cellulose in the leaves exerting a
"this end up" spring tension? Bob Fenner>
Lilies d'Amour or lilies no more? 9/27/05 We have
frontage on a fresh water lake. The lily pads have overtaken the water.
We can't swim, boat etc. We've tried pulling them out by hand
and with implements but it is evident we are losing the battle. Any
ideas? <Mmm, a few... there are chemical herbicides that one can
utilize... but these are pretty non-specific... and I don't know
what your neighbors might think if you killed their lilies... And
there's the issue of legality... where the water might go...
irrigation, watering of livestock... There are biological controls, but
these might posit the same issues... and then there is/are the manual
side... it may come as a "happy surprise" to you to find that
there are companies willing to buy your lilies... I would check your
phone directories for pond service companies in the region re... and in
turn, cast your net further, contact the national pond livestock
suppliers (these are listed on WWM)... the cooler weather is upon us...
so the lilies will die back... next year? Perhaps a combination scuba
training/weed removal classroom....? Bob Fenner> Water Lily
Control Question We have a pond proximately 55 feet by 75 feet,
with a depth of approximately one foot around the edges to
approximately 7 to 8 feet at the center (it is shaped like a bowl).
<How nice!> We landscaped it with some cat tail on
two sides, as well as other pond flowers, and we put a fountain in the
center that works from early spring until late fall.
<Okay> Three to four years ago we made a big mistake in planting
water lilies on the back/far side of the pond, directly in the ground
in the water. During the first two years the pond looked
beautiful with the lilies blooming all summer long in small yellow
flowers. However, last year the water lilies somehow
multiplied (perhaps the fountain pump in the center sucked in the seeds
and sprayed them out all over) but the lilies spread and covered al of
the pond surface area with thick pads of leaves during the
summer. Although this is good for the fish we have in the
pond, it gives them shade and food, the pond does not look like what we
want it to look like. You hardly see any water anymore, just
the lily pads and leaves. <I see> We try to clean the pond three
times during the summer but it I very difficult to do because the water
is very deep in the center, it comes above your head, and the only way
to clean the pond is to float on a raft and pull out the lilies by
hand, which takes a long time and is very hard to do on a hot sunny
day. <Have spent MANY hours doing this myself> Do you have any
advice for us as to how to put this lily problem under control, perhaps
trim or prune them or even destroy them? Can we use any
tools you can think of to cut them 5 to 10 inches under water easily
because they come back within a few days and the stem is 6 to 7 feet
long under water from the bottom. Do you know of any company
that produces any tools (like weed eaters or grass cutters) that can
work under water? Also, do you know if we don't let them
grow above the water and reproduce seeds, would it be possible to
prevent them from growing the next season? Or is there
anything you know of (or can direct us to someone who may know) that we
can do to put them under control without destroying the life and the
fish that are in the pond? <There are gardening hand tools like
"Hula Hoes" that can be adapted (longer handles) to cut the
lily pad and flower stems near the bottom... and a possibility of
diving to hand-remove the tubers... and chemical means (a bit dangerous
to all livestock if too much is killed off all at once)... that can be
broadcast via sprayer or pellets... even biological control means in
some places (triploid carps of a few species)... nothing to just slow
down for a season> I would greatly appreciate any assistance you
could provide. Thank you in advance, Blagoj Panovski
<Having worked in water feature design, construction, maintenance
for several years... I am given to suggest, if the problem is
"that bad" that you drain the basin, let dry, and use a power
tool (back hoe, skip loader...) to scrape the area clean, start again,
with either blind potting the lilies or building berms... likely wire
and re-bar, with some concrete/shotcrete... possibly a liner... to
control their further expansion. Bob Fenner> Shade tolerant Water
Lilies Are there varieties that will tolerate five hours of a 12
hour sunshine day in the shade? <Yes, most hardies do fine in this
arrangement... and a few tropicals... they won't blossom as often
or long, but will do so nonetheless> I have a pond with a large old
Oak and am told it must go. But I really don't want to lose such an
old tree. <Me neither... I would just regularly remove the leaf
litter from your oak. This is the real source of possible trouble. Net
out the leaves once a week and you should be fine> Do you have any
ideas as to where I can find varieties like this? Thanks Bill Richards
San Angelo, Texas <Yes. Most all of the mail-order water garden
suppliers carry shade-tolerant nymphaeaceans... Van Ness, Lilypons...
use your search engines with the terms: "water garden
supplies". Bob Fenner>
Waterlily? I grow a plant in a pot, which in our
country is referred to as 'Waterlily'. I am sure it is not, but
I can find neither its Latin name nor its common name. It has
very large roundish leaves and produces one flower a year growing on a
long stalk. Can you please suggest its name? <Perhaps it
is a Nymphaea species... very likely a member of the family
Nymphaeaceae... Take a look on the Net with these terms. Bob
