New wildlife pond - Confused!

Hi,

I'm new here and to ponds! I think I've bitten off more that I can chew so have come for some advice.

During a week off at the beginning of February I dug a pond, I'd fancied a simple wildlife pond for a while but hadn't had the spare time until then, so I'd thought about it idly right up until I found myself buying a spade! Its about 2 foot deep at the deep end with a large 1 ft deep shelf, its roughly 1metre long and 3/4 metres wide, I'd collected rainwater all through thee proceeding autumn and winter and was able to fill it 3/4 full before the end of my week off. 2 sides of liner are dug in with some mossy turf holding the edges in, one side is dug in to a little bog garden and I'm planning to dig in the remaining edge as a bog garden too, but life snuck up on me and I've to do this by increments. I've left a "hump" all the way round to separate the bog from the pond, I'm hoping the moss and bog plants will eventually grow over the exposed liner. Its been too cold to add plants yet so its just water with some gravel in the short end to help passing wildlife get out if they fall in. The rain over the last few weeks has topped it all the way up and the bog is delightfully boggy already!

My main concern is over the time its been sitting there earth has fallen or been washed in, not huge amounts but a fine dusting over part of the deep end, the water is looking a tad brown which makes me worry its all out of balance. I'm hoping to get some oxygenating plants asap now its warmer but I don't know if they will survive long enough to do their work if my water has already gone wrong? Also, can I add my shallow water marginals before my deep water oxygenator has done its work? I want something tall to pop out in the shallow end and I want to put in something like frig bit for surface coverage, I want all native!

At the moment its quite shady, in the summer it has a lot of sun, with dappled shade from a near by bush, but when the sun is low in the winter the shadow from the fence covers most of it. I do not plan on adding fish, this pond is for passerbys only - I'd love to get some frogs/toads/newts turn up at some point but I'm not planning on adding any living creature that doesn't find their way there themselves. I have no filter, I want nature to look after the pond herself .

Any advice greatly received! All my google searches bring up results about filters and koi which doesn't help at all!
 
If it's a true wild life pond nature will take it over ,So don't need to worry about to much Adding some marginal plants and few bunches of Hornwort and Elodea should help with floating plants ,you could give it a couple of weeks ,still a risk of sharp frosts depending on location, Make sure frogs and Co can have easy way out

The problem with soil is that it encourages rampant plant growth, which isn't what you want in a small pond.

This is what happened to mine.
2010 <"Little Shop of Horrors - How EI frightened the gardener">.
2013 <"moss in the pond">
2015 <"Journal - Lockdown wildlife pond"> in 2018 it had a reset <"Get your garden out">
2019 <"Get your garden out">

I've had another go at it in winter 2023, and I've removed a good wodge of Eleocharis palustris (you can see it in the 2015 photo), but it will be back to where it (and I) started by the end of 2024.

What about adding watercress? It grows in my pond, in London, through out the year, even when the pond is iced over! All you need is a bag from a supermarket - just throw in any leaves on stalks. You can always pull it all out later in the year when you get plants you prefer.

But don't eat it!

This is just the natural look i would love to get! Not a very talented gardener though so I will just have to plant and hope!

Really? From the supermarket? I'm so trying that! I'm still hanging back on the plants as the temperatures keep dipping, but if watercress is hardy it might help it along in these early days!
 
Don't worry about it, 99% of ponds are never balanced, it's just a goal that is never achievable since one day its ok, next day it rains and changes the "balance" so long as it is not choked with plants or decaying matter and looks nice, don't worry, enjoy what you have.
Relieved! I think Newbs like me always sweat the small stuff! I'll trim back the plant life if I need to, but I'd rather let it do its own thing if I can.

The very first thing I did was pile up some gravel as an escape route. I'm going to buy some bigger stones to make it a bit more robust, I always planned the shallow end to peep out above the water during the warmer, dryer months as I would love to see the birds using it as a bath! They're already drinking from it.

Hornwort is my first planned purchase and I want some good ground coverage in the surrounding bog garden like creeping jenny, but I'm torn on taller plants. Can anyone recommend a good native grass that will spread and give some height? And any flowers that might attract pollinators? For both the shallow end and the surrounding bog?
 
I have a few of the floating planters in mine. I use creeping jenny and water mint to give them stability, and various other plants in them for height. Try to use a fair bit of gravel in them so they don’t float too high in the water (makes the creeping plants lay more flat).

The middle floating planter was newer hence the edge of it being more noticeable. The other two is nicely overgrown now.

Hello! Sorry to come back and demand more information but I'm still confused! I seem to have an algae bloom in the pond now, which is pretty impressive given how little sunlight we've had so far this year. Its a type of algae that is swirling throughout the water rather than sitting on the surface. I added plants about 2 weeks ago, there is an submerged oxygenator in the deep end, which is growing at a cracking rate! I need to lower it already but with the water so murky I don't want to deprive it of light. I also have a water iris and a pygmy lily in the shallow end, although the lily is currently miniscule, just 5-6 tiny leaves just brushing the water surface. I took previous advise and chucked in a bag of water cress to yum up the extra nutrients and pretty much all of it survived! I have loads of healthy growing water cress plants, some free floating, some anchored by stones and a few potted in a little aquatic soil.
It has rained pretty incessantly, I did wonder if that could have stirred everything up? There's been a few sunny days but the pond still has plenty of shade. A rosemary bush planted at one side that has been struggling for a few years has had a second wind, its doubled in size and produced huge volumes of flowers. Unfortunately with the strong winds a lot of these flowers has found there way in to the water - could there be too much debris already? It feels a bit nuts to think i would need to go out skimming everyday, it is meant to be a nature pond after all!

I'm wondering if it could be the aquatic soil that has boosted the algae? It has become much murkier since the plants went in and despite putting pea gravel over the top they did all loose a puff of soil to the water when they went in. I'm not massively bothered about the appearance, I want to it to be healthy and natural but I don't know how healthy the water is when its so murky. I have a bottle on my kitchen window sill, so far no sediment and its still green, but some of the green has kind of swirled together to make a darker green cloud.

What, if anything should I do?!
 
Hi all,

It is <"partially the time of year">, you usually get a bloom of green filamentous algae in the spring <"Pond algae and blanket weed / RHS Gardening">, before you get a huge amount of vascular plant growth. As the strands thicken up, and photosynthesise, it will tend to float to the top, buoyed up by the oxygen from photosynthesis.
I'm wondering if it could be the aquatic soil that has boosted the algae?
Quite likely, but even the <"traces of nutrients in rainwater"> will support some green algae.
What, if anything should I do?!
Probably just leave it, if you get a thick layer of "blanket weed" you can then physically remove it. Algaecides <"are worse than useless">, but over time it should reach some sort of stability.

Thanks! I did wonder if it was just a new pond thing but as I've never done anything like this before I was worried I'd messed it all up. And I really didn't want to be adding chemicals if I could avoid it. I will watch and wait!
 
Hi all,
Can anyone recommend a good native grass that will spread and give some height?
They are all a bit rampant. Have a look at <"Water meadow gardening">.

If you were set on a grass? Glyceria declinata <"Glyceria declinata | small sweet grass /RHS Gardening"> is possibly your best bet. Catabrosa aquatica <"https://species.nbnatlas.org/species/NHMSYS0000456975"> would be another option, but I'm not sure where you would get one from (possibly seed?).

I tried "Gardeners Garters" (Phalaris arundinacea "Picta" <"Phalaris arundinacea var. picta | gardener&s;s garters Grass Like/RHS Gardening">), but it was still much too vigorous.

You could <"try a Sedge">? Carex elata "Bowles Yellow" <"Carex elata &s;Aurea&s; | Bowles&s;s golden sedge Grass Like/RHS Gardening"> would do or Carex pseudocyperus? Or any of the smaller species <"Journal - Wildlife Pond Project">, Carex panicea is a good "blue" leaf. The best behaved "grass" I have is a rush, <"Juncus ensifolius">.
And any flowers that might attract pollinators? For both the shallow end and the surrounding bog?
You have a much wider choice there. If you want native ones? Have a look at Buglife <"https://cdn.buglife.org.uk/2019/07/Bug-friendly-ponds.pdf">, and the Bumblebee Conservation Trust <"Pond plants for bumblebees | Bee The Change blog"> but I would definitely have Water Mint (Mentha aquatica), Brooklime (Veronica beccabunga) and Lesser Spearwort (Ranunculus flammula). They will all grow in the "shallow end". I like Greater Spearwort (Ranunculus lingua), but it is a rampant grower.

If you want native ones for the bog? Creeping Jenny (Lysimachia nummularia) is good, you might also want to look at Marsh Bedstraw (Galium palustre). They aren't native, but "Candelabra Primula" are good, and the easiest one is probably Primula japonica. There is also Primula denticulata , which I like, but it is a bit of a "marmite" plant.

Thanks!

I raided a pond specialist centre near my mum's (160 miles down the motorway!) and got some nice pond side flowers, the creeping Jenny is completely thriving! The others haven't down quite so much yet but they look like their settling in. I ummed and ahhed over grasses and reed like plants as I did read they could be rampant. I have taken a punt on a couple of native varieties. The bog areas are quite small and contained so worse case they will just take over the area I popped them in. I also relented and picked up a pygmy lily, its not native but European and apparently hardy, and I also got a water Iris which is loving its spot in my pond and probably needs repotting already! I read they are hungry little plants that should help to reduce excess nutrients in the water.

The watercress tip was awesome! I've got little flurries ow white flowers and lots of green foliage starting to cover the pond sides. Bargain for the price of a bag from Asda!

Still no frogs. But our garden is relatively enclosed and I think I might have the only pond on our block, I might have to patient for little tenants in my pond.
 
I made a “uk native wildlife pond” last year and it went through lots of unsightly phases including …
Brown murk=will settle
Green murk=add daphnia
Hair algae=more plants, inc watercress
Dog bath=hosepipe

And now it’s clear, plants have grown in and full of life , newts, frogs, tadpoles, dragonfly larva and lots of micro fauna
Seeing the first dragonfly made it all worth while
Give it time and enjoy

Hi all,

You might not get frogs, but you will probably get Smooth Newts, they occur in all sorts of unusual places.

Cheers Darrel
I know my frog chances are low, but I'm not without hope! We had a huge toad move into our garden one year, living his best life under our shed, and I've encountered many frogs on the nearby boulevard. We have a significant water way about a 5 minute walk away, so we're hotching with wildlife, they just need to find the gap beneath the back gate, which is really our only wildlife access.

I would love newts! If newts of any sort found their way in to my pond I could die happy!

This is beautiful! thanks to uneven garden two of my sides are very steep so I will never get this level of natural look, but I hope mine beds in to look half as good.
