| Iceman: The replies may be a bit flippant, but they're the truth. You can cover the surface of the planting tub with large stones (preferably rounded) to prevent digging in the soil, and some folks have tried metal grid work over the plants, but eventually the lillies fail or the koi get into the tubs, or the koi hurt themselves on the contraptions. Small koi do well in a lily pond until they grow to the size of a large goldfish. Then the problems begin. Little inconveniences at first. Then bigger problems until a disaster occurs. You will see lily ponds with small koi that have coexisted for years. Inquire and you'll find that actually the koi die and get replaced, or the koi are kept small by very limited feeding. A person told me once how great koi did in their water garden... that there was a real ecological balance, so good, in fact, that they only fed the koi once per week because they got natural food from insects and such. The koi were under 12", and at least one was 4 years old. But, you know, that koi was alive. Probably would have been culled if it hadn't had that watergarden as a home. Folks on this board are pretty serious about their koi. You may find more information at koishack.com in the gardening forum. It's a great place for checking out varieties of lillies in bloom and such. Some knowledgeable watergardeners there, and most know something about koi, too. |
