sphagnum moss as growing medium?
Comments (12)I wrote this on the Fig Forum not long ago. You may find that it pots the "danger" of handling sphagnum moss into perspective. Some of the secondary info may or may not be on topic, but I think you'll find it interesting: Yes, you CAN catch Sporotrichosis, which is a fungal infection, from handling sphagnum moss. It's often referred to as the Rose Gardener's disease, since thorn pricks are a common way of introducing the fungus - barberry and brambles like blackberry and raspberry are also known sources. The fungus is also (u>commonly found in soil, on flowers and shrubs, on wood products, timber, forest litter, and various other mosses, so it is almost certain it could be found in potting soils that include any of these products (most commonly do). The most common source of infection is the house cat. It should also be understood that not all sphagnum moss carries Sporotrichosis. The Wisconsin Division of Health, Bureau of Community Health and Prevention (BCHP), investigated a 1981 diagnosis of Sporotrichosis found in two brothers employed at a garden centre in Wisconsin. The investigation revealed two additional cases of Sporotrichosis among the employees. The garden center had sixteen workers make funeral wreaths during the Winter of 1980. The infected moss used was harvested from bogs located in central Wisconsin and was purchased from a single wholesale dealer. However, in an investigation of a local cemetery where 12 employees produced 2,000-3,000 wreaths per autumn using sphagnum moss purchased from the same Wisconsin supplier, no additional cases were noted. Again, use your own judgment, but it appears that the source of the outbreak was limited to just one bad batch of sphagnum from a wholesale dealer who had also supplied countless quantities of Sphagnum free of Sporotrichosis. Bear in mind that the risk of Sporotrichosis is very small; in the US the incidence of infection is not precisely known but is estimated at only 1-2 cases per million people, and most of those cases are from sources OTHER than sphagnum. An estimated 200-250 cases occur per year, nationwide. Statistically speaking, it is far more dangerous to cross the road than to handle the moss. I know you'll use your own good judgment and common sense when/if you use it, but it is an effective antifungal/antibacterial medium, acting against those strains/species of fungi/bacteria that cause problems when we are trying to root. It's been used as a wound dressing for hundreds of years, and as a favored medium of experienced horticulturists for rapidly inducing roots in air layers and cuttings. Bonsai practitioners have long used it as intensive care for trees that have contracted root rot because they were grown in heavy mediums with excessive water retention, commercially prepared and packaged potting soil being a primary offender. Sphagnum moss has excellent internal water retention properties, however unlike sphagnum peat, in its live form it is able to retain its open structure and so is fast draining and well aerated. Less well known is that Sphagnum moss contains a high zinc content in the form of a naturally occurring antibiotics/antifungals called Tropolene and Sphagnan. The anaerobic bacteria common in heavier soils that cause the decay that inhibit woody cuttings from rooting are nullified by the antiseptic properties of Sphagnum moss. Hence, pure Sphagnum (without the addition of any other organic material) is considered by most experienced horticulturalists to be as close to a perfect medium for root induction as you will find.

Comments (11)I have a T-shirt that says; "Some complain that roses have thorns, I'm happy that thorns have roses" While I don't advocate you stop growing them, I do think, if the thorns bother you that much, you should do what Hoove said and grow something else with no thorns. I often come in from a day in the garden looking like I lost a fight with a cat. I'm scratched and bleeding. I keep my tetanus shot current and wear goat skin gauntlets that I buy by the dozen pair and happily work away with my roses. There are many thornless and almost thornless varieties but choices are limited so you may not have varieties you like....See MoreEver heard of sporotrichosis?

Comments (62)Khalid: I didn't see your message until I came back to this thread. Thank you for what you wrote: " I regularly use black tea with ginger and cinnamon. Honey (with black pepper if I have a source throat), cardamom (small and large), garlic (as part of all our curries), onions (an integral part of our curry), as well as a few more herbs, spices etc." All those have anti-viral and anti-bacterial .. I agree with using food as preventive medicine, rather than dangerous flu-shot (combining virus). Carol: Glad to hear that you are back on schedule .. I am delighted to hear of your progress & success. It feels SO GOOD to have looser pants, and I wish everyone have that experience with daily exercise. Sam: does your Achilles tendon hurt to wear shoes with heels? I don't like shoes with heels: one of my foot is shorter than the other. I actually do more exercise on the treadmill than outside ... I can wear my husband Walmart open-heel plastic clog, I insert a memory foam inside ... and wear that on the treadmill. I wear size 7 woman, but I need a BIG shoe to insert the thick $5 memory foam. The plastic clog has bigger toe-box than running shoe, plus no need for lacing....See More- 8 years agolast modified: 8 years agophoggie thanked rhizo_1 (North AL) zone 7
