I bought tree plastic cages for planting water plants.
We took canna out of a pot, and divided it by hand. Its rhizomes were bound tightly each other and it was hard to divide them.
Most of rhizomes were canna, and sweet flag didn't grow well.
So, water canna and sweet flag were not planted in the same cage. Water canna in two cages, and sweet flag in one cage.
Three cages were placed in the pond with a pot of lotus.
Remaining canna rhizomes will be planted somewhere else. We are discussing about it now.
In the pond, we keep small fish 'Japanese rice fish' (Oryzias latipes) . They were presented by a man who have a large pond in his biotope. They eat mosquito larva. We netted them to confirm that they survive. We found eight fish.
We wish the water plants flower beautifully next year.
