I joined this forum today to get some expert advice on orchids, and somehow got sucked into the pond section for about half an hour instead. Lovely ponds, everyone! It's nice to see what other people are doing. Here are some photos of mine. Three are from different sides of the pond. The fourth is a close up of a water lily. These blue water lilies are real thugs. They crowd out and strangle every other variety I have tried to plant. I have let them take over because they look so nice.
I live in South India where daily maximum temperatures range from about 25 to 41 centigrade. I have to top up the water level every week or so and pull out surplus reeds every few weeks. Apart from that, it looks after itself.
