Taro, they don't like taro, it tastes like glass to them. :regular_waving_emot
I love hyacinth, problem is, so do the koi, they eat the bulbs
and destroy the plant in a few days. They even rip off the moss -- like a bad toupe,
on our precious moss rocks !
This is what we do, we continually rotate the hyacinths ( and water lettuce too)
between the
biological pond and the main pond. We call it going to rehab, the koi munch on
the hyacinths for a couple of days and then we scoop they out and put them
in the biological pond and replace the ones we took out, with last weeks
hyacinth. If you don't have another pond, use a large tub or kiddie pool to hold the hyacinth.
Be sure to use mosquito dunks in the tub or kiddie pool.
The water lettuce fair much better in the pond than the hyacinth does.
