Title: Floating gardens to grow difficult plants the easy way
Post by: partisangardener on December 01, 2021, 05:39:34 PM
Since Corona began, my moveable floating gardens increased in number and beauty.
A simple form is this one, floating on my rainwater tank. This one is from beginning of August and the picture is about end of october.
It comes in handy when you have cuttings or seeds which would need maintenance. I just put them there and everything takes roots or germinate.
In addition it looks good and no animals drown there.

I had started iwhen Corona came a new bog garden. Since it is so easy and takes next to no time for care I started now at every available space now a lot of these floating gardens. Especially for plants which take a lot of expertise to grow. Like Cypripedium and alpines.
The best thing is, you can leave it for month without anybody taking care.

I would like to try this in my new small pond but I suspect it would have to be protected from birds stealing the moss for nesting in the spring. It is fed from water butt overflow at present. Now to find some suitable seed. "Dacs" seed themselves in my pots in the garden but nothing else at present. I only really had water lettuce floating on it this year, which I got for nothing.

I had on this special one no birds acting. Maybe it is a bit irritating that the island moves when a bird is landing on it.

I have now about forty water filled 90 liter buckets with my islands.
But the ones shown in the link just a few meters away have a netting. My blackbirds are pretty bad here. Since the one shown exists only since last August, I will see how it works in the next nesting season. I am also working on solutions which are not as ugly as the usual ones.

I am too already working on ceramics which would hide the plastic optic. Pretty similar to the ones I put around my bog in the link.

Here are some of the plants thriving therein:

Cypripedium tibeticum (low ph)
Cypripedium reginae   (medium to low ph)

Pogonia ophiglossoides
Epipactis palustris seedgrown there in acidic ph
Dactylorhiza praetermissa (neutral ph)


Drosera binata
Drosera anglica
Drosera intermedia
Drosera filiformis
Drosera linearis*+seeds

Pinguicula grandiflora
Sarracenia alata
Sarracenia rubra

Sarracenia purpurea dwarf form
Sarracenia leucophylla seedgrown and plants from BG Prag
Darlingtonia californica mountain population Oregon seed grown

Chamaedaphne calyculata nana  seedling
Andromeda polyfolia
Vaccinium vitis-idaea
Vaccinium myrtillus
Vaccinium uliginosum

Iris chrysographes seed grown black form
Iris setosa
Mentha requienii (weedy)grows extremely well, very hardy there but overgrows everything
Fritillaria meleagris
Fritillaria camtschatica grows very well, pretty low plants without ferilizing

Primula veris red form (seedlings)
Primula integrifolia
Primula matthioli
Trillium grandiflorum
Soldanella hybrid

Gentiana acaulis
Gentiana pulmonaria

There is no substrate below the waterline, so it is always aerated. It simulates  the conditions of a natural seep, or a rock constantly washed by water.
Even plants which grow usually under quite dry conditions grow quite well. Especially alpines and mosses do well.
The water tank and evaporation on the moss cools this environment (could be interesting for city climate, if used a lot)

The soil conditions vary of course with the thickness of the substrate. Through seeds I try out what works best. for a desired species.
To get different mycorrhiza I took small pieces from interesting habitats to to inoculate different floating pieces.
The thickness of substrate is only one method to vary moisture. Another one I use, is flat pieces of styrofoam, stones or even plastic onto the soaked fleece.
So in result I get different moisture levels without much substrate.

This system is maybe adabtable for a lot of problematic eco-systems

Cypripedium reginae was for many years in my old bog garden. 2020 in spring I transplanted it in a new setup. The original 2 olants had made two seedlings.
Not jet flowering. These flowered this year.
Growth was slow but good in the past years. But in the new setup with continuous water supply it seemingly exploded.
It is so dense I will have to make three out of it.

Rectangular rafts tend to stay not level if build up too high. As a solution for one like  the Cypripedium acaule container I tried this solution.
I fixed a slab of granite with some wire to the bottom.
like this or for the slender rectangular ones.
Title: Re: Floating gardens to grow difficult plants the easy way
Post by: partisangardener on December 04, 2021, 05:51:50 PM
At the Moment is the 90 liter container full. So my plant-raft floats on top.
In general I recommend round buckets and rafts. They wont topple until being very high.
But if you use small pieces for keeping plants apart or not waste Styrofoam a small slab of granite or suchlike as ballast underneath comes in handy.
You can create small landscapes even with Bonsai, which are more easy to maintain than the old type. And it is no big deal to have them for a short time as a table decoration inside, in a nice ceramic bowl.

This one was a birthday present a year ago. It floats on a small pond for two season now. Birds did visit it but the growth of the moss is too strong for them.
Additional it clings quite well to the cloth.
Title: Re: Floating gardens to grow difficult plants the easy way
Post by: partisangardener on December 04, 2021, 06:39:42 PM
The last generation is round an on top some border out of Styrofoam, nailed to the raft with toothpicks. Finally a cover of Micro-fleece and in the middle a wick from the same material.
The fleece shields UV rays from the Styrofoam and after very short time the Moss cover will do the same job for ever.

The row of tooth pic surrounding it serves the purpose to fix moss onto the rim, until it fixes itself there through its growth.
Some mosses have strong root like structures, some not like sphagnum. But it sticks quite well after a time and in sour habitats I prefer it.

Post by: partisangardener on December 04, 2021, 09:04:24 PM
The advantage of floating substrate is, that there is always a very thin layer of water there, which is always saturated with oxygen and anaerobic microorganism have no chance.
It is not the water supply alone. Excess water flows always into the main water body without much organic material.
Your setup has varying oxygen levels, which I try to avoid without much maintenance.
The quite excessive water body will keep for month without intervention or rain and if it rains no water will suffocate the substrate.
I quote that here because there seems to be the chance of misunderstanding the idea.

Post by: Véronique Macrelle on December 05, 2021, 07:28:31 AM
for the cypripedium, you put what thickness of soil.
and only peat?

 and for Trillium grandiflorum?
Title: Re: Floating gardens to grow difficult plants the easy way
Post by: partisangardener on December 05, 2021, 10:17:29 AM
I have 15 cm for Cypripedium tibeticum and a bit lmore than 20 cm for C.reginae.
Trillium grandiflorum is in the same trough as C.reginae. Seedlings grow already in less than 5cm. I think this is sufficient for this species.

With my method  the waterreservoir-funktion of the substrate is needless. Like in the thriving mats of vegetation on waterfall rocks
When I tear apart the Cyps coming spring   I will give them not more than 15 cm and some will do with less than 10.
I did not expect them doing that well.

Hi.
I have just read many of your original postings in 2014 by using Google to translate, when you constructed the bog area. Questions in my mind are where the water comes from. Is it a natural source? Is it there all year round or do you have to control, or add to it? Sunlight is not obvious in many photos; is it in a naturally shady area that maybe slopes? In later photos a fence appears. Is this the same garden/area?
Apologies for all the queries, but it is such an interesting concept. I doubt I have enough rain water for a large area but on a smaller scale I might manage something next year. I still have a large round hole that was supposed to be a pond a few years ago. ;-)

These are different gardens. The first on from 2014 is a patchwork type with ordinary filling. Sand , lime free gravel,peat apart from what you see.
worked quite well, but I had to water it sometimes when I had longer dry periods and it took a lot of material.
It had a floating part in a small pond. In the end I had to give away the more interesting plants. Only the Cypripedium were still there when Corona hit. And of course the material and more ordinary bog plants and mosses. This one was most of the day sunny, only partly (time and space) shaded by fruit trees not too close.

The already ingrown one from beginning of Corona is in front of the place I live at. Only sun in the late morning until 13 o clock. To make up for the poor light I constructed at its north side a mirror-front to increase the light, which works sufficient.

The plastic troughs are  pretty moveable and are not always at the same place. Some are in front of my flat. Most are at a friends place in a ex military compound . Nearby, but much more rain. These had this year excess water and there I have 3000 liter rainwater reservoir.
This area slopes in some places. Area offers every possible sun or shade.

If growth is not sufficient I place another plastic trough at a better spot. Then put the raft on some foil and then carry the water to the new one.
Alternatively I can exchange the rafts between the different buckets.
All water I have is rainwater collected from housetops or solar panels. Our tab water is good, but has a somewhat high Ph . I had yet no need to use it.
For special  plants and in case of emergency I have sulfuric acid.

If you prefer plants from acidic spots I would do it elevated in your area, then it does not get contaminated from the surrounding soil. The military compound is on a chalk mountain.
But there are a lot of interesting plants possible on chalky soil.
The small birthday present (8) floats on a pond near the military compound and has a lot of chalk stones around and in the water.
But Sphagnum species and Sarracenia still grow well on such a floating raft. Much is to be tested and these raft conditions allow much more than one would think. This would not work in a pot, chalk level would accumulate.

Axel this is a really interesting thread, please keep us updated.

Floating fen and bogs are widespread in nature so I suppose we shouldn't be surprised that this works. If I can think of somewhere in the garden to put one, I'll give it a try.

Best wishes from Wales.

One of the advantages of this method, it doesn't require a long term space of a garden from the beginning,a empty water bucket is swiftly moved. Comparative little work and little care needed, compared to a regular seedbed in the garden.

A friend urged me to sow on these islands Pulsatilla occidentalis which is probably a bit difficult.
Apart from some orchids I disseminated these and some Gladiolus palustris, Primula maximowiczii and a lot of other plants.

Each different raft has only a few seeds of each species because different mycorrhiza is to be expected. Transplanting is very easy. The soil is very fluffy. Anything I pick up will grow on without pause on another raft.
This is my experience as far.
Title: Re: Floating gardens to grow difficult plants the easy way
Post by: partisangardener on December 16, 2021, 12:25:08 PM
If I succeed I just give him some of these floating seed beds.

My next goal is to make rafts out of empty plastic bottles. Grown in they should look as natural as the other ones.
Much more accessible than hard Styrofoam.
Title: Re: Floating gardens to grow difficult plants the easy way
Post by: partisangardener on December 20, 2021, 01:30:32 PM
Some plants need more light and a cooler habitat.
My first bog arrangement has only 6 hours sunshine In the afternoon until evening there is only shadow from the house.
So it keeps quite cool through natural  evaporation. A mirror background provides enough light, and doubles the scenery.

Now it is two years old and I can harvest moss and other plants for the new rafts.

Hi again
Am I correct in assuming the absorbent fabric/fleece, apart from being used as a "wick", is only used to hold the pots onto the flotation material? It does of course also provide a growing base and background for mosses etc, outside of the pot itself. I could also just wire the pot to the float, for practical purposes. I have found a source of the fleece fabric in a local dress fabric shop; ~£8 a metre, 1.5 metres wide. In green (and many other colours) of course ;-)

Merry Christmas to all, Brian

Post by: partisangardener on December 23, 2021, 10:19:15 PM
There are no pots or suchlike in this system. All (really all) plants grow on the flat surface of the floating Styrofoam above the waterline. That is what supplies the optimum growing conditions and the high oxygen level at the roots.
To cut holes into Styrofoam to insert pots is not nearly as good.

For a starter the colour is a bonus. But moss and the plants will cover whatever its colour is.
The starter thing on my first post, has apart from moss some peat on it. When I had to sow some seeds, I just pushed some of the moss aside, added some peat and the seeds on top. No pots needed a natural growing hummock.
Title: Re: Floating gardens to grow difficult plants the easy way
Post by: partisangardener on December 24, 2021, 11:06:58 AM
I started some seed beds with sparsely some sand grains on top. Germination was very good, even some Orchid germinated there. For mycorrhizal fungus I spread some living roots of Erica on top.
https://www.srgc.org.uk/forum/index.php?topic=18290.0
After the second season I put this late autumn some peat on top, Growth was not sufficient in my opinion. Especially Gentiana seedlings grew very slow.

But Drosophyllum was going quite strong without any substrate apart from the fleece. It was very hungry at the beginning, so I placed the whole thing outside and the little natural food there kept it going.

At the moment I experiment with alternative rafts. Lots of empty plastic containers pollute our environment and are easy to access. (Here in Germany not that easy)
My idea is to put them into a synthetic pillowcase and put the fleece and some substrate on top. The moss and other plant cover will protect it of UV ray degradation and these floats could accumulate lots of CO2 while they last and look good too.
Title: Re: Floating gardens to grow difficult plants the easy way
Post by: partisangardener on January 02, 2022, 09:10:46 AM
Bog plants in pots, often have problems with anaerobic degradation in lower parts of the container.

The oxygen-free zone in a natural bog is usually much further down than in our containers.
To keep the oxygenated state in your substrate I can offer several more solutions.

You could use containers with grill structure (I do not know the term in English) to ventilate the substrate.

You could use some mesh-bag as a container. I experiment at the moment with cut off legs of old trousers, stitched up at one end.
They probably tend to be overgrown by mosses and will hopefully look quite natural then. Synthetic material will last longer. Moss will shield it from UV-ray.

Addition of structure matter like heather twigs helps too for aeration in these situations. Live Sphagnum in strands up to the surface works on the long run too (heads up of course). Only in the bottom half it works for a limited time, because it disintegrates soon and looses structure.

Long dead strands of Polytrichum ssp. moss work for a very long time. They are very resistant and provide ventilation for a long time.
They work quite good for me alive, but you end up soon with a clump you cant divide without a chainsaw or a laser beam.

My idea is to put them into a synthetic pillowcase and put the fleece and some substrate on top. The moss and other plant cover will protect it of UV ray degradation and these floats could accumulate lots of CO2 while they last and look good too.
One pillow case is already filled with some Coca Cola bottles and some waterbottels both plastic and already covered with some moss. Alas snow is on top, so no picture. The next set is already waiting. I let it float in another pillowcase, to see how they take heavy weather.

Possible that I get more of a similar size until spring. Maybe a simple solution for capturing excessive CO2 out of the atmosphere lies in the plastic garbage we already have.

Post by: partisangardener on January 24, 2022, 08:08:54 PM
Because it was asked for, I have an update to explain some of my systems in more detail.

The first islands were frameless or with flat Styrodur sections (2-3 mm attached with toothpicks, except for the right Cypripedium thibeticum part, which has a 15 cm frame, which I glued with construction glue and stabilized with bamboo skewers (rods from garden bamboo).

For the rain barrel part and some others I only put moss cushion parts on it. When I had to sow something, I pushed the moss aside and applied substrate and seeded it there.

 

Most of the frame parts are narrow sections and really only necessary when they are outside and there is a risk that a heavy rain will wash everything away before it has stabilized.

 

If you have enough moss cushions, you can simply make a frame out of it at the edge and fix it with toothpicks. They then catch washed-off seeds etc. and also grow relative quickly with their rhizoids. I still do these and it seems to work well.

 

Sphagnum works quite well as a cushion (even if it has no rhizoids), but if you want to settle individual moss threads you can also tap in half a toothpick at short intervals and then weave the moss in. I cut  curtain rods plastic packing into strips.

But I found the idea with the toothpicks better when I thought of it because I couldn't get hold of those transparent plastic strips anymore.

 

Covering the whole system with acrylic glass plates against heavy rain are too unwieldy in the long run with the amount I have and they would also be expensive if you don't get a few sections for free like I did.

So I also cut with 2cm Styrodur-plate strips and framed these seadplates afterwards. So that the seeds are not washed away.

 

That works too. Only the Drosophyllum has died because I probably pinched off roots with the flat edge strips (it was on the edge). I'll start some new again soon.

 

Now I lay out short pieces of toothpicks at intervals of 5-10 cm before I install edge strips made of Styrodur.

 

A good but slow-growing moss for the border is Riccia fluitans.

since i read you, i have been looking for suitable polystyrene pieces, but they are less and less used (and so much the better for the planet, no doubt).
I also have this problem that the water holes in my garden dry up every summer almost now and I have completely lost my sphagnum moss and the plants that went with it.
maybe this is a solution for some plants:what minimum raft size did you make?
I found a small piece of styrofoam about 15 cm in diameter...

Title: Re: Floating gardens to grow difficult plants the easy way
Post by: partisangardener on January 25, 2022, 08:26:20 AM

The smaller ones are a bit more inventive. To get more material on a round  island I choose some old military underwear. Cut of the legs and sewed the leg opening and filled it with topsoil  from a root plate.
Moss grows there very quickly. When the Cypripediums are in flower again it will be all green.
Title: Re: Floating gardens to grow difficult plants the easy way
Post by: partisangardener on March 03, 2022, 06:11:27 PM
Some look more advanced. When the underwear rots away, the roots of the plants and the moss will hold it together.

Cyprpedium reginae on two Islands start to grow.
Title: Re: Floating gardens to grow difficult plants the easy way
Post by: partisangardener on April 03, 2022, 06:45:04 PM
This Cypripedium was divided Beginning of March. I accidentally broke off the tip of a new shoot. Since then it stayed on one of my special islands in living Sphagnum amongst a lot of twigs and shoots I try to root there.
I had no big hope but anyway I tried. There things like this don't need any further attention.
Today nearly a month later I plugged  it up and it had changed a bit. It is at least a third longer and has grown a waist thinning and looks quite healthy.

I am no longer certain that it will die. What do you think?
Title: Re: Floating gardens to grow difficult plants the easy way
Post by: partisangardener on April 12, 2022, 01:38:07 PM
Make the floats as fat as you can get.
Snow and growth of the plants should not be underestimated.
The habitat of my Cypripedium tibeticum was today 5cm above the float. there was only 10 cm substrate above the waterline.
There was also some old Root on top which soaked over the wintertime.
I had to put another 5cm plate underneath.

Losses are not yet visible. I keep you updated. Apart from the C.tibeticum everything is already good looking. I dug a bit and stopped after the first green.
It was firm and already green.
Title: Re: Floating gardens to grow difficult plants the easy way
Post by: partisangardener on April 14, 2022, 08:22:14 PM
Two sprouts of C. tibeticum already appeared. I hope they stay.

A third one appeared. I took the chance and removed the Sarracenia leucophylla rhizom wich I parked there, last spring before the Cyps appeared.
Too near as always.

A simple way to place a netting is to stick 4 to 6 thin pipes (metal, plastic or bamboo)into the ground.
Cut some half-rings out of bracing wire (I use 3,8 mm) and stick it in the tubes
This is an easy framework for a netting.
I fix it at three sides with some hooks (metal or sticks from the hedge)
The front part is weighed down with some metal rod for easy access.

Trillium grandiflorum flowers now on two of the rafts. Cypripedium reginae has recovered from the dividing.
I have cross-pollinated all of them.
Last year some mouse or so  stole the fruits. But the seedlings from the year before have already their second leaf.

My latest addition to the floating gardens are some D.majalis. Two groups living together with some pieces C.reginae.

I hope they will cope with the conditions. It is 40 days ago since I became them.

Cuttings from Daphne tangutica from last autumn lived till last week. As i removed them since they lost their leafs, there was no more roots visible.

Next time I use some of the few  calciferous islands I have now.

Cypripedium acaule developed quite well. The other one next to it did not turn up.

The bigger parts are set into square buckets, the same size as the original one.

Cypripedium reginae in this bucket is already 70 cm high.

Cypripedium reginae on most islands. Apart from one island where I buried it too deep. After I dug it up it does not look too good. One bud rotted away and the other one looks quite bad too.
Maybe it recovers.
This single one looks perfect

Lilium canadense (seeds 2021) grow their first leaf. The germiating bulbs were very small.
Leafs are quite big for these dwarf bulbs.

A friend let me have some seeds from gladiolus palustris from his garden ex Königsbrunner heath near Augsburg.
Quite a lot germinated. One was quite different, all white leaf. After a week it turned light green.
Today I found on another Island a pure white one and another light green one.
I hope some of them will grow up.

I have a different setting for plants which like it more on the drier side.
Bottomless is one choice, the other one is a wicking system.

I cut a side of the pots bottom. pull a wick through. One flat piece outside the other one on one side up to the surface of the potting soil.
This set on one of the wick coated islands as shown in the pictures.

No maintenance needed.

I had several islands with Meconopsis x Sheldonii. Germinated on several, but only one grows well.
All have different soil and mycorrhiza

The revival of Cypripedium reginae which was the only one which looked after division awfully is still growing.

Germination of different Drosera like filiformis without substrate was very good. But without feeding and no substrate the dwindled an quite a lot died after the second year.
After I put the piece of cloth on some substrate they started to recover.
The ones which I sowed this early spring on several Islands with fresh substrate grow much better.

The Lilium seedlings  are L.canadense. They grow on all islands well and are on most of them.
