So, I am going to try to do some of the opening of my pond this year. Just starting as the weather permits. I think I am okay with the mechanical and chemical, not so much on the cleanout. My plants all sit in pots in the water. There is a lot of last years dead growth that needs to be trimmed off. Can the plants sit out in the pot in the air for several days? Also there is green fuzzy algsr on all the rocks. Should I power wash all of this off?

Here is a pic

I would trim off the dead growth and bide your time. Do you have fish? If so, I would just wait and let spring do its thing. Every year, before the plants really start growing, the pond begins to wake up. The fish graze around more and poop more. The algae grows to help process the waste. I wouldn't pressure wash the fuzzy algae. It serves a purpose and it's really pretty!

Thanks everyone. I have attached pics. Some plants are marginal, though most are in pots

I am guessing that I should cut off anything that looks dead, but if I am supposed to cut the plant all the way down, I don’t know that. Also the Lily’s down in the bottom of the pond look nasty, do I just set them back upright and see what happens?

Do you have a fine mesh skimmer net you can use to get the leaves and other debris out? You could even grab it out by hand and put in a bucket, then use as mulch or compost in the garden. All that decaying matter is contributing to the waste ("nutrients") feeding the algae. I'm not an expert on the plants and what or how much to cut. I was afraid to cut too much off, myself! @addy1 ? @Lisak1 ?

Anything that looks dead can be cut right down to just an inch or two above the root ball. Some of my reeds and grasses I just yank them out - the dead stuff pulls out pretty easily.

As for the lilies, I would generally suggest cutting those back in the fall, but it's not a super big deal. You'll probably find it's basically mush by this point, so you can either just leave it or try to scoop it out. Anything else that's dead in the bottom should come out, either with a net or get in there with your hands and scoop it out. The fun part of ponding!

By the way, all your marginals are reeds or rushes of one type or another. The one that's kind of curly is a corkscrew rush. The others are harder to identify at this point, but probably blue rush if I had to guess without seeing it green and growing.

I chop all down in the fall, anything missed gets hacked in the spring. The lilies are groomed hard in the fall. Removing leaves, old flowers etc and any tubers that look dead or are just too big.
