Thanks for any/all help...

You are a bog gardener after my own heart! Here is the method I've used to create a bog for carnivorous plants as well as native orchids, cranberries, and a bunch of other great plants. It's actually the hand out I give out on the occasions when I've spoken on this sort of garden.

Creating an artificial bog garden

Strange as it may sound the first step to building a bog garden, dig a hole! The area can be whatever shape you like about 18 – 24 inches deep and slightly raised from the surrounding bed area to keep runoff from entering the bog (this is explained shortly). Locate the bog garden where it will get full sun at least half the day, preferably afternoon sun.
The worst part is done! Now line the hole with rubber pond liner. Don’t worry if there are sharp roots etc. that could puncture the liner. A few leaks do not matter.
Begin filling the bog with the following combination: add 1 bale (4cuft) of sphagnum peat, mix in 100lbs of silica sand and a big mess of conifer needles (white pine is my favorite). Add rain, distilled, or dehumidifier water till saturated. This is the second hardest job because peat is extremely hydrophobic. Repeat above until the bog is full and fully saturated. Sculpt the "dirt" such that it is low in the center and higher around the edges. Because it is saturated and all the air is worked out, it will not settle.
If you wish to plant a Fen type garden (ph neutral and slightly more nutrient rich) add 50 – 100 lbs of calcium rich lime in place of the conifer needles. Most species of Cypripedium will prefer this to the bog garden. I made the mistake of using crushed oyster shell, it added too much salt…so don’t use this for calcium!
Time to plant! Place plants that like more water near the center of the bog where it is low and plants that like less water around the edges. This works well because the edges dry out far faster than the center. Be patient! A bog garden takes at least 2 years to become well established as a mini ecosystem. Don’t pull any weeds that you are not sure are weeds! Some really good stuff can come to your garden from peat bales. But keep seed heads of sedges and other more aggressive plants trimmed so more tender plants will have a better chance of survival.
The cardinal rule! NEVER EVER EVER WATER WITH ANYTHING OTHER THAN RAIN, DISTILLED, OR DEHUMIDIFIER WATER! TAP WATER WILL KILL A BOG GARDEN IN A SEASON AS WILL ANY SORT OF FERTILIZER!
Plants suitable for bog gardens and sources

There are a number of plants that are suitable for bog gardens, many are readily available others far too scarce. Listed here are some of the plants I have had success with and enjoy in my garden. Remember when looking for plants, be sure to buy from sources that propagate their stock or (in the case of orchids) are from documented salvage operations. These are plants that were removed from habitats just before the bulldozers come in to build the next strip mall. This list is NOT exhaustive and you may have luck with plants I have failed with or think I’m crazy for planting "that".

CARNIVOROUS PLANTS
Sundews, Drosera filiformis, D. rotudifolia, and D. intermedia
Sarracenia Species especially purpurea and those that produce best pitchers in spring.
Venus Fly Trap Dionea muscipula. I’ve found it reasonably hardy here (my plants have survived -5F)
UNCOMON PLANTS
Bog rosemary Andromeda and Heather/Heath Caluna species.
Sedges and rushes especially corkscrew rush and cotton grass (sedge).Be careful some of these can get out of hand!
Gentians, great fall flowers. Patience is required to get them established.
Blue and yellow eyed grasses and smaller members of the Iris (Iridaceae) family.
Call me crazy but no bog garden would be complete without Poison sumac (yes it is in my garden). Most wonderful fall color, but don’t touch!
Orchids
Cypripedium or lady’s Slippers, C. acaule (pink) for the bog garden, C. reginae (showy), and C. candidum (white) for the "Fen" and C. pubescens (Yellow) and it’s relatives for a partly sunny spot in the Perennial bed.
Fall blooming Spiranthes or Lady’s Tresses, Small, fragrant, and a great companion to fringed gentian. These self seed in the bog!
Platanthera species, the fringed orchids, especially P. ciliaris (yellow) and blephariglottis (white). There is also P. psycodes (purple) but it is NOT an easy plant to grow!
Calopogon tuberosa, the grass pink. Showy and easy, Epipactis gigantea, giant hellborine, great if you can find a source, Dactylorhiza spp. (European) a good garden candidate, and Bletilla spp. A great garden subject needing no special care.
Sources

See the web sites for the above at www.orchidmall.com click on sources!
If you have questions feel free to contact me at: fbess7600@msn.com.

It does take some patience to get the garden well established but once it's there it takes minimal work to keep going in the form of limited weeding and watering with only rain or distilled water. Judith, You may also be able to grow additional plants that will not survive Cleveland Ohio winters. If you'd like some sources drop me an email and I'll send them off to you, they are part of the above post but I could not figure out how to separate them (they all ran together when I copied and pasted!)

Happy Bogging!

Fred, you should post a few photos of your bogs!

I don't have a source of pine needle (that I know of, at least). I'll try to find some. If I don't find a source, can anything else be substituted?

Can I use lake water if rainfall doesn't come when needed? Lake Michigan is nearby. What about sump pump water? I know I can buy distilled, but these would be easy substitions, if they are appropriate.

If I keep my lawn organic, can a bog garden be placed in an area with potential for some limited run-off in a really heavy rain. I'm on a slope and I have to be careful with grading so the water won't end up in my basement.

Thanks for the help.

Fred, what is the white flower and the yellowish orange flower in the second picture?

Rainwater is best, the water from the lake should be OK, as long as you're not too close to where there could be pollutants. Sump pump water is a BAD Idea, loaded with minerals you don't want. A 55 gal. rain barrel works really well for me, as does water from my dehumidifier.

Some runoff from an organic lawn would not be terrible, but there will be a few things that will probably not grow with that situation.

The white flower and the yellowish orange flower in the second picture are Monkey face orchid (the white one) Platanthera integrilabia, and the orange fringed orchid Plantanthera ciliaris. In another month I'll have loads of Spiranthes (white ladies tresses orchids) in bloom through the end of October.

Thanks for the compliment! That bog was part of an article in the Wall Street Journal last October, not to mention my pride and joy!

The P. integrilabia came to me from documented salvage and was labelled as P. blephariglottis. I have several plants that have over the past few years multiplied vegetatively both of the P.i. and P. Ciliaris. I have done a bit of pollinating so perhaps I'll have seed for flasking (I dabble in that in the off season)

I did have a question regaurding the instructions. I saw the depth dimentions for the starter bog, but no other size dimentions. How long, and wide should a bog be to house that much sand, pine needles, and peat?

Thanks so much,
Jason

My bog is about 4'X5' but you can make it whatever size you wish. The bigger it is the more stable it will be as far as growing conditions.

Lynt,

My bog only has surface water after heavy rains and only for a short time. My rain barrel is another matter and I've started using mosquito dunks, which will also work in the bog if it holds water for a longer period.

I was also curious as to when the best time to start a bog garden is? ( sorry if this has already been asked and I missed it.)

Cheers

Happy bogging all

While visiting my family in CA last month, I visited California Carnivores twice and shipped home several gorgeous plants - thanks to Peter's help and advice. Additionally, I had purchased about 2 dozen specimens off the Internet, so I had quite a variety to get started. So far, I only have pitcher plants, fly traps, bladderworts, butterworts and sundews. I look forward to adding a great number of others - thanks to Fred's wonderful suggestions -next year.

I also have a new pond going in this week and as soon as that and the deck near it are completed, then I can seriously get started on designing the final home for my bog. Right now it's appearance is quite utilitarian, but as soon as all the pond building paraphenalia is gone I will finally be able to get near it again and take a picture to post.

Thanks again for everyone's help - I can already see that this new delight is going to start competing with my ponds for real estate space!!!!!

My ponds are now dug, but they are going to have to wait out the winter before I get them completely installed. 2 ponds, upper and lower, with a stream connecting. these are in the same general area as the bog gardens and like you I placed the ponds next to the deck I had built last year.

Keep me posted on how things fare through the winter, perhaps I'll have a few things to share in spring

Fred

I plan on putting gravel in the bottom with the outlet pipes from the pump. The water would then be pumped up through the gravel, then thru sand, then thru pumice and then through peatmoss and finally compost/soil.

Does anyone have ideas on how I can keep my sand from collecting pieces of bio material (dead leaves etc) from the bottom of my pond and then getting the sand clogged up?

How big should I make the holes in my pipes which feed the water to the bottom of the bog?

Ideas and suggestions are welcomed.... should I put a pool sand filter before the bog-filter...at least that way I could backwash the sand filter.

Should I use silica instead of sand? If sand, should I use fine or coarse sand?

Many thanks for any input.

1. Wont run-off from rainwater (if the sides of the liner are not higher then ground-level to prevent the entry of run-off) cause an influx of nutrients and minerals that will accumulate over time?

2. Will Cranberries overtake a CP bog, being too invasive, or can then be easily pruned back to certain areas? I want to make my bog 3' x 30' (strip) with the cranberries in the middle and the CP towards the edge.
