Just like the fish in your pond,
your pond plants need nutrients
to thrive. Since a pond is a closed
system, the nutrients plants
normally get in a more open
system (such as a lake or stream)
may need to be supplemented.
Plants absorb essential nutrients,
such as ammonium, nitrates, and
phosphates, from your pond's water,
helping clarification and overall
health of the pond. Minerals that help
plants absorb these nutrients include
potassium, manganese, and copper.
Types of fertilizers
Supplemental fertilizers that include
these minerals come in different forms,
depending on the media you use, the
plants in your pond, or the maintenance
you wish (or don't wish) to do.
You may find that the planting
media you use, such as CaribSea
Kahuna Soil or API POND AQUATIC PLANTING MEDIA, contain all
the minerals your plants require,
without need for supplementation.
Potted plants, like lilies, can benefit
from regular fertilization from tablets,
Plantabbs Pondtabbs Aquatic Plant Food . An easy way to
"dose" tablets is with the long-handled
Nycon Plant Feeder. No need
to enter your pond to fertilize – simply
place tablet into end of feeder, plunge
into plant's soil, and release the tablet.
Time-released fertilizer offers little or
no maintenance. Try Laguna Fertilizer
Spikes which only
need to be placed once per year.
Whatever you use, it is always
safest to make sure any additives
you put into your pond do
not contain excess levels of
nitrates or phosphates.
