Prologue:
Because this seems one of the easiest plants to find
on the market, I decided to cover it again in more detail. I
originally included it in my Bunch
Plants page as one of the hygrophila
varieties. Since it's so popular, I've decided to cover it in more
detail. Let's just say it's hard to screw up this particular plant.
LA
Three giant hygrophila plants in a pot of fberglass substrate.
Potted Hygrophila Corymbosa:
When ordering a quantity of mixed potted plants, we
often receive some giant hygrophila in the assortment. They usually
grow faster than any of the other species in the assortment. The
rooting medium
used in these plant pots is a fiberglass foam. Potted plants are often
grown emersed in hydroponic trays. They arrive with stouter stems and
occasionally with flowers. You see no flowers when you grow hygrophila
submerged. You'll see no roots like these when the non-potted plants initially
arrive. As you can see, the giant hygrophila very quickly sends out
adventitious roots. Good root growth nearly always means good leaf
growth will follow.
LA

Newly Arrived Hygrophila Corymbosa:
Potted plants do not usually arrive in full fledged
display foliage. They arrive in a sparse condition (which they soon
outgrow). As you look at the nodes on the stem, these are the places
where roots or leaves or both can grow. Usually the roots grow on the lower
level and leaves grow on the higher levels. If you look closely,
you'll detect a new stem growing at that second node from the bottom.
This is the way temple plants grow into display plants.
LA
One Month Later:
These potted temple plants grew to this size in a 55
with fluorescent lighting. Most people remove the pots (with scissors)
and stick their roots in their tank's substrate. We leave the pots on their
roots to make them easier to handle when we sell them. You can cut the
pots off at home.
LA
The non-potted plants usually arrive in rubber-banded bunches.
Non-Potted Hygrophila Corymbosa:
When planting non-potted specimens, we stick them in
any kind of substrate and can count on them rooting in two to three weeks --
sometimes less.
These particular specimens are three weeks old -- lots of roots.
LA
Different substrate here.
More Non-Potted Hygrophila Corymbosa:
Type of substrate makes a little difference but not
much. Smaller natural gravels let the roots grow faster. Larger
colored gravels slow their root growth but only temporarily.

All hygrophilas grow best in b-b size substrates.
LA
Yellow leaves come loose easily. Yank thm off.
Hygrophila Corymbosa's Main Disadvantage:
As the top grows, the new top leaves tend to shade the
lower leaves. Once they turn yellow, they become unsightly and
probably should be removed. Also, when the stems become too long, you
need to trim them back and start new plants. The original plant
branches out two new stams where it was "topped off."
LA
Yanking out this growing tip tmakes your original plant bushier. Two stems will
usually sprout at this new top node.
Advantages to Trimming:
When you snip off the tops (with scissors or
thumbnail), you encourage new growth at the node you liberated. This
makes your temple plant grow bushier and more attractive (IMnonHO).
You can also start new plants by planting your trimmings. As a general
practice, you'll get more success when you remove the leaves from your
bottom two nodes. Be sure to leave at least three pairs of leaves in
your new "cutting."
LA
You can make any plant bushier by removing its growing tip.
LA
Ready to prune back to make it grow bushier. We'll make two plants
from one. Just an experiment.
LA
Cut in half March 22, 2011.
LA
Planted side by side March 22, 2011.
LA
April 3 and 12.

April 14 & 16, 2011.

Artful clipping can make giant hygrophila busier and more attractive.
LA
It takes a while to grow a show plant from one of the "starter stems."
LA
These were starter stems we discarded.
LA
If the stem is still soft, the plant will orient itself toward the light
source.
Phototropism:
Growing plants tend to twist around in order to
expose maximum chlorophyll to the sun.
LA
Add Fertilizers?:
You can encourage plant growth by adding an aquatic
fertilizer designed for aquariums. If you plant your giant hygrophila
in a tank with fish in it, you probably won't need to add fertilizer -- at
least at first.
LA
Guppies cannot harm giant hygrophila, but ...
LA
... the jury's still out on African cichlids.
LA
High Light:
These particular tanks receive light 24 hours a day.
We're finding out if giant hygrophila can stand up to African cichlids.
So far they ignore it.
LA
Pottedplants are easier to care for.
LA
Singe stema usually cost less.
LA
Last Words:
Which ever choice you make, you'll find these plants
make attractive, easy-to-grow additions to any aquarium.
