I would skip it for containers and trees planted out, unless your soil is granitaceous or very sandy. There is very probably no value in the excess P (7-10 times more than necessary) or the thiamine. The only fraction of the product that might have the potential to be beneficial is the IBA it contains, and I think that is more than offset by the potential negatives associated with the excess P.

I just Googled Superthrive to see if I could find a retailer near you. I had no luck. (There may be a retailer link in there somewhere. Personally I found the website so over the top, retro, right out of the fifties that I had a difficult time wading through it all). The website is giving away free samples!

I once received a small rooted plant from Sweden. Actually it came from Germany, was mailed to Sweden, and hand carried to Kansas City, where I got it. It had been wrapped in loose wet moss in a ziplock, and it rotted off all the leaves; so, I was left with a stem with a healthy tip (an episcia). I took the moss, squeezed out excess moisture, and potted the stem back into it, in a small regular pot, putting the now potted plant back in the ziplock and placed on the window sill. I was at the convention that week, so it had to make do with a hotel room window sill. By the time I was ready to head home to California (five or six days later), it was starting to recover, with leaves so tiny they needed a microscope to see them ;). It survived its plane ride, went under lights, and grew into a plant, which I now grow. So, the "moral" of this story is: I rooted it in long fiber moss (New Zealand type is best but American long fiber sphagnum moss works well too), in a small pot, enclosed in a ziplock bag and in good light. After it grew a healthy shoot I propagated it again into a standard gesneriad mix (peat, perlite and vermiculite). I agree with Nancy, a shot glass just doesn't sound right. You need a small pot with drainage. When I pot an unrooted cutting, I will take some dry moss and thoroughly wet it to total saturation in the sink, then take it in my hand and squeeze out the water. I take that compressed ball of well squeezed moss, fluff it up again and lightly place it with cutting in the pot, not compacting it at all. In the loose moist moss and enclosed in the bag the roots are exposed to lots of air and very high humidity. They then shoot out through the moss capturing all the moisture. Once you have roots going wild, then a light feeding will speed things up. Jon PS: When you say you got a gesneria, do you mean a plant of the genus gesneria or are you using this word in the old fashioned sense, as a general term for a gesneriad? Really, this term should only be used for plants of the genus Gesneria. Plants in that genus need high humidity, constant moisture, and should never be allowed to dry out. They often are best grown in terrariums or in small pots under enclosures like sweater boxes or domes. Many plants in the genus Gesneria can be hard to root.

Very interesting information! I must admit I am brand new to the gardening world- learning as I grow! I purchased the root stimulator last year upon advice from an associate at a local and what I consider a trustworthy, family-owned nursery in town. That being said, I assumed he knew what he was doing and bit the bait! Thanks for the input that it is a waste of resources! I heard the same thing on the hydrangea forum. We purchased our home in Athens a year ago. I discovered multiple beauties growing in my yard once spring of last year hit! Hostas are very happy here under a canopy of beautiful white oaks! I had to relocate several of my friends this year. I learned the hard way that our neighborhood deer eat hostas like candy! So, it sounds like what I am hearing is to leave them alone as long as they are in happy soil and getting plenty of water? What should I fertilize with if anything?
