What is so rare as a day in Spring? Well in MD, they really are rare! The average temp this time of year is 70F, but that usually means days of 55 intermixed with days of 80. Finally, yesterday was actually in the upper 60s, which is MY kind of weather.
I spent almost the entire day outside. The major project was to clean out the small pond. I have a larger pond, but that project is for another day.
I have to mention first that I covered the pond with clear plastic because the Spring Peepers drive me crazy at night. If there was 1,000 it would be OK because the noise would average out. But I get just a few and there is a loud crok every minute or so. Its like the Chinese water torture! So, for sleepfulness, I cover the pond when they are mating.
The first thing I do in a major outdoors project is set up a rest station. Hey, I'm 60 years old! Chair, radio, beer. In the shade...
Here is the pond when I uncovered it. Live plants...
But purple sludge! My first thought was "red algae bloom" (toxic). I washed my hands frequently. I made a hole in the muck to get a hose siphon started.
It's easy. I just laid out one hose downhill and attached another from the spigot to it. Fill the first with water, disconnect, and get it in the "hole" in the pond fast. Here is the downhill end of the siphon hose.
It took an hour to siphon (hence the need for radio and beer), but it was finally done. Look at the mess I saw!
Meanwhile, as the siphoning was going on, I weeded the garden. I dug up quite a bit on some invasive grass. Nasty stuff that spreads by long underground runners. I used to know the name of it, but it escapes me now. Suggestions welcome.
When the pond was drained, I mucked out the bottom silt, Its great stuff for the compost pile! A pond skimmer net is good for getting that stuff out.
Because of the red algae(?), I sprayed it with chlorinated water. I don't know if that will kill it, but it sure won't help them any (search for WC Fields and moths). I scooped the remaining water out with an old pitcher and poured the rich silt-water on the neighboring flowers.
When I had the pond about as clean as I could get it , I refilled the pond center about 4" deep. That's so I can set the surviving plants back in some water tomorrow when the chlorine has mostly evaporated out.
They all need repotting. I tried that last year and failed badly. Some pots floated and some just fell over. THIS time, I have gravel to mix with the soil and bits of broken flagstone for the bottoms of the pots to weight them down.
The repotting was necessary because, 3 years ago, I discovered that the entire pond was a mass of roots. Stupid me, I didn't know that they grew roots out of the pots!!! And it had been 5 years since I planted them. I spent hours cutting the various pots apart (the roots were all intertwined). And that was in the cold March water (I still shudder from the cold water)...
But this year, it is going better. I have the stuff to repot them properly (read up on it at pond plant website). And I am going to put a waterpump in there this year to keep the water circulating. Does anyone know if those U/V filters really work? I might try one.

Lots of work but nice when it's finished.
Around here that would be a 3 beer job.
We have Creeping Charlie around here. Long runners, thick blades offset on the stem. But we're Minnesota so it's probably an Eastern plant you have.
It's 38 here and we had sno- flurries this morning. What month is it? January? -sss's mom
Hi I have the same problem of the purple sludge in my pond that is how I found your blog :)
Lots of hard work you've done there. In England we called that grass "Couch Grass" and it is a pain to clear so well done you.
Just wondered did the purple sludge disappear of it's own accord? I'm still in a pickle about mine.
:)
