Sedges

Out of sheer frustration trying to keep my fish pond/pot going, I intro’ed a couple of baby sedges after most of the so-called water plants died, and even the duckweed gave up.

Sedges will grow half in water, and in my past life, when I had a frog pond going for years, swamp plants were a strong feature. These often have their roots and soil substrate in the water, and their leaves above. s

I suspect they somehow condition the water, enabling other plants to grow. I certainly never had any problem keeping either Azolla water fern or duck weed alive and used to raise dozens of tadpoles to frog-dom.

If I knew anyone with karamat I’d go and beg a cutting but haven’t seen it since leaving the Byron Shire. Both these sedges are usually quite weedy though the little one at the back as far as I know is native to Australia.

‘Weeded’ them both from the local verges while out walking. One of them from the creek overflow. About ten days in their new position they don’t look like they’re dying.

The pebbles are to provide an island for bees and other insects to drink. (Though I need to top up the water.) And if I pour the water onto the pebbles there is hardly any disturbance in the water.

There’s one lone Pacific Blue Eye remaining of the seven fish I got for my birthday 10 months ago.

Duckweed …

As you can see when you zoom in, most of the duckweed is white and dead.

I’ve been keeping fish and frog ponds for about fifteen years and I’ve never had such a wholesale dieback that even the duckweed carked it.

The feathery green plant seems okay so far. Fingers crossed that they make it. And, I hope that both the Azolla waterfern and the duckweed have left spores and seeds behind, that hopefully will sprout when we leave winter behind.

While you are zoomed in you may be able to spot the two remaing fish. Though they look like leprosy warmed up in the photo, in their analogue state they‘re stockier than they were, but at least still alive.

I moved their habitat back under the outdoor light, in the hope that that gives the plants enough light to survive until I get my grow lights. An added bonus is that I can sometimes see the fish flitting about from inside my living room.

Azolla Water Fern

Azolla water fern are one of my favorite plants. Theyfix oxygen and keep the water underneath fresh.

Indtead I’ve got a great dying. I managed to keep them alive and thriving for 14 months, through moving house, twice changing water, mud, and water again. Now all dead and brown, I don’t know why.

Too cold? Not enough light? Water poisoned somehow? Fish nibbling on the roots? Only two fish remain and they are carniverous. It’s a mystery.

The chickweed are doing very well, thank you.
