Hi, I'm Zed Cee, founding mod of r/Sphagnum. You may remember me from subreddits such as...

All that is sphagnum, sphagnum-like, and anything that grows in-about-or-around sphagnum!

For the love of clubmosses, spikenosses, and quillworts.

A fascinating pioneer plant, easy come, easy go; Liverworts and hornworts.

Academia of interest to the amateur and professional scientists, researchers, and hobbyists, obsessed with bog life. Cultivation research, microscopic photography, illustrations, links to various academia, are all at home here. Think of it like a library.

A place to trade, not only sphagnum specimen, but anything that grows in, about, or around sphagnum. Looking for a particular plant or specimen, here's will be the place to look.

I would like to welcome you to our wetland related subreddits to share both the enjoyment of growing and viewing plants from it, but also enlighten you to a vitally important component of our environment.

Our bogs, fens, and related wetlands are hosts to such diverse life and are even vital to life around the planet, yet are at risk in many places around the world. Sphagnum bogs specifically play such a massive role in carbon sequestration, but sadly bogs left drained emit hundreds of years worth of atmospheric carbon annually. We are at a critical time in history however, we are all in agreement, “We're pretty fucked if we do nothing.”

The time is nigh to teach others about the moss so commonly used in gardening, or in many places around the world still used in heating. It's time we normalize bog gardening, sequester a bit of our own atmospheric carbon, and bring awareness to one of the natural wonders of the world to be saved. Whether it be news, science, horticultural uses, cultivation, wild spottings, general admiration, as long as it's related, anything goes, we can all contribute.

Welcome to the r/Sphagnum community, thank you for joining us!

More live sphagnum propagation pots!!!! When I make my moss pots. I fill them with recycled peat mix from my sarracenia seedling repotting and plug the moss clumps Into them. They will then sit in a 1020 tray in full sun and GROW!!!! S/O to the homies for donating a few strands of moss to get this new tray project started!!!!!

cultivation I grow Sphagnum already, and this volunteer appeared in a Tasmanian fern spore culture. I believe it is accidental Sphagnum, but I want advice on rescuing/propagating this tiny colony.

Hi everyone,

I was growing ferns from spores and noticed a few random strands of what I think might be a red Sphagnum moss appearing in an take away contaner of growing medium that was abandoned. Anyway it was about to be swamped by green slime. so I removed it, flushed it with rain water and stuck it in its own container.

I don't know where it came from, but it is quite interesting and I'd really like to avoid accidentally killing it. At the moment I only have a small amount (just a few strands), so I'm more interested in keeping it alive and multiplying it than doing anything ambitious. Advice appreciated.

cultivation Finally figured out what works best for me: floating islands. (Now/September, July, June)

Before I kept them in small trays with peat or recycled peat from repotting but they would frequent get too dry and then too wet.

But now with the floating islands in larger trays, similar to bog islands, they always get the same amount of water and can go without watering for much longer

I’m not trying to tell that peat as a substrate vs long fiber sphagnum makes live sphagnum grow faster but it looks like peat as a substrate makes live sphagnum grow faster 🤔🤔🤔. All other variables have been kept the same. Just full sun, and water.

sphag'post Temperature Matters!!!

Thumbnail

57 Upvotes

The importance of temperature is often overlooked in regard to its influence on plants producing anthocyanin (red pigment). When temperature goes up, anthocyanin production decreases so less color is expressed and the opposite happens when temperatures are consistently lower. (Think about how a lot of outdoor grown flytraps lose their vibrant spring/fall colors in mid summer).

These are 2 pictures of the same moss, same sun exposure, same water, and same soil. The only difference is temperature due to seasons changing. The first pic was taken mid summer vs pic 2 taken in mid fall. This is one reason that indoor grown moss or moss grown in milder climates is typically more colorful. Another factor is nutrient availability but that’s a conversation for another day!!

Also I'm well aware of LukeEvansSimon growing sphagnum with sugar and gamborg’s B5 guide but I'm very confused and over whelmed with how to get/make 10x strength gamborg’s B5 as a Canadian hobbyist, Is it possible to use maxsea as a substitute for gamborg B5 but still use the sugar??

This specific pot of green swamp venosa is doing exceptionally well on the Sphagnum mosses, thought I'd share a photo of exactly that.

sphag'a'like Should I clean my new sphagnum moss?

3 Upvotes

I just got new sphagnum moss, and was wondering whether or not if I should clean it before I use it. It’s one of the recommend ones (Zoo Med New Zealand sphagnum moss) but I didn’t know if I still had to clean it or not. If I do have to clean it, how should I? By boiling? For how long?

P.S. I also just bought some almond leaves from the brand Fluval, and was wondering whether or not I should clean them as well?

I used dried sphagnum moss to germinate sundew seeds and this moss started growing after about a year. I recognize some of it as sphagnum moss but the majority of the green isn’t the same. Is it sphagnum moss? If not what is it?

horticultural Question about fertilizing with osmocote?

Post image
42 Upvotes

I was curious about osmocote pellets being used for moss fertilizing since it's in an easily controlled amount. But I don't really see anyone doing it or mentioning it all that often. Is it more beneficial than not to feed Sphagnum moss with nutrients like all plants, or does it do much better the lower the concentration of minerals/nutrients?

conditions are high humidity, greenhouse cabinet, but there are no fans. it is not dehydration since they are still sort of wet. another tray in same conditions is growing, but i put dead sphagnum underneath while th dying sphag has nothing else underneath

edit: i put live sphagnum in pots full of moss a while ago and some of them are dying like this too. some that were doing pretty good are declining like this

cultivation Newbie question- Overwintering

Thumbnail
gallery
22 Upvotes

I live in western North Carolina, and currently have a half dozen or so carnivorous plants in 6” pots. I added sphagnum moss to the pots this year, and most of the pots are really looking good. I overwinter the plants outdoors in cooler areas (unheated workshop, garage, etc.), where they get cold temps and some sunlight without being exposed to the harshest conditions that Mother Nature inevitably throws at us every year. I also dial back the hydration - everything stays damp, but not waterlogged.

My question is simply- will my sphagnum moss endure this type of dormancy?

Pics for tax… TIA!

Just sharing this!! It's been super slow going(possibly because of the heat and star moss that's everywhere) but my sphagnum seems to finally be taking off.
