A blast from the past: My Superthrive experiment. ;-)
Comments (9)This was published in Stemma Magazine: Superthrive or Superjivecolor>size> The question regarding the value of Superthrive as a miracle tonic for plants is often bandied about in horticultural circles. Over the years, I had read claims that ranged from, "I put it on my plant, which had never bloomed, and it was in full bloom the next day." to, "It was dead - I put Superthrive on it and the next day it was alive and beautiful, growing better than it ever had before." I decided to find out for myself. If you look for information on the net, you will probably only find the manufacturers claims and anecdotal observations, both so in want of anything that resembles a control. Though my experiments were far from purely scientific, I tried to keep some loose controls in place so that I could make a fair judgment of its value, based my own observations. Here is what I did, what I found, and the conclusions I made about any value the product Superthrive might hold for me. On four separate occasions, I took multiple cuttings of plants in four different genera. In each case the group of cuttings were taken from the same individual plant to reduce genetic variance. The plant materials I used were: Ficus benjamina, (a tropical weeping fig) Luna apiculata (Peruvian myrtle), Chaenorrhinum minus (a dwarf snapdragon), and an unknown variety of Coleus. In each instance, I prepared cuttings from the same plant and inserted them in a very fast, sterile soil. The containers containing half of the cuttings were immersed/soaked in a Superthrive solution of approximately 1/2 tsp per gallon of water to the upper soil line. The other half of the cuttings were watered in with water only. In subsequent waterings, I would water the "Superthrive batch" of cuttings with a solution of 10 drops per gallon and the others with only water. The same fertilizer regimen was followed on both groups of cuttings. In all four instances, the cuttings that I used Superthrive on rooted and showed new growth first. For this reason, it follows that they would naturally exhibit better development, though I could see no difference in overall vitality, once rooted. I can also say that a slightly higher percentage of cuttings rooted that were treated with the Superthrive treatment at the outset. I suspect that is directly related to the effects of the auxin in Superthrive hastening initiation of root primordia before potential vascular connections were destroyed by rot causing organisms. In particular, something I looked for because of my affinity for a compact form in plants was branch (stem) extension. (The writer is a bonsai practitioner.) Though the cuttings treated with Superthrive rooted sooner, they exhibited the same amount of branch extension. In other words, internode length was approximately equal and no difference in leaf size was noted. As a second part to each of my "experiments", I divided the group of cuttings that had not been treated with Superthrive into two groups. One of the groups remained on the water/fertilizer only program, while the other group was treated to an additional 10 drops of Superthrive in each gallon of fertilizer solution. Again, the fertilizer regimen was the same for both groups. By summerÂs end, I could detect no difference in bio-mass or vitality between the two groups of plants. Since I replicated the above experiment in four different trials, using four different plant materials, I am quite comfortable in drawing some conclusions as they apply to me and my growing habits or abilities. First, and based on my observations, I have concluded that Superthrive does hold value for me as a rooting aid, or stimulant if you prefer. I regularly soak the soil, usually overnight, of my newly root-pruned and often bare-rooted repots in a solution of 1/2 tsp Superthrive per gallon of water. Second, and also based on my observations, I no longer bother with its use at any time other than at repotting. No evidence was accumulated through the 4 trials to convince me that Superthrive was of any value as a "tonic" for plants with roots that were beyond the initiation or recovery stage. Interestingly, the first ingredient listed as being beneficial to plants on the Superthrive label is vitamin B-1 (or thiamine). Growing plants are able to synthesize their own vitamin B-1 as do many of the fungi and bacteria having relationships with plant roots, so it's extremely doubtful that vitamin B-1 could be deficient in soils or that a growing plant could exhibit a vitamin B-1 deficiency. Some will note that I used more of the product than suggested on the container. I wanted to see if any unwanted effects surfaced as well as trying to be sure there was ample opportunity for clear delineation between the groups. I suspect that if a more dilute solution was used, the difference between groups would have been even less clear. It might be worth noting that since the product contains the growth regulator (hormone) auxin, its overuse can cause defoliation, at least in dicots. The broad-leaf weed killer Weed-B-Gone and the infamous "Agent Orange", a defoliant that saw widespread use in Viet Nam, are little more than synthetic auxin. Al...See MoreBlast from the Past
Comments (16)Hi everyone! I thought I'd update all of you who have taken those trips down memory lane. I have received more information from the directors about what decades are going to be on what day. Here's what I've decided to do so far: Tuesday: (50's and 60's) I'm still at a loss! I think the loom potholders are going to be too expensive to do with 150 people and I can't find anything super cheap to tie dye. I might check with the directors to see if they have decided on shirts yet and if not, maybe they can go with white and we will tie dye them. What kinds of things did you decopage? Wednesday: (70's and 80's) There were so many good ideas, I had a hard time deciding. However, I was on the Hobby Lobby website the other night and saw that they had candle making supplies for 50% off so I went and got wax and wicks for 150 candles. I also had the kids at school save me their milk cartons for a couple days to use for the molds. We will make the crushed ice candles with these using old crayons for the coloring. I'm also wanting to do something with shrinky dinks and possibly pet rocks if we have time. (What did you do with the shrinky dinks? Jewelry?) Thursday: (90's) I'm planning to do perler bead keychains and pony bead animals. I hated those things, but the kids seemed to love them. Friday: (present) We always make a picture frame, so I'm going to make them out of clear CD cases. We will probably put a piece of cardstock in and stamp around the edges, then cut the picture to fit in the middle. To make it stand, you open the case, and bend the case back as far as it will go without breaking. You put the black part on the table and the clear part stands up. If anyone comes up with answers to my questions, please let me know. Thanks! Beada P.S. I'm sorry you hated Girl Scout Camp! I happen to be directing a Girl Scout Day Camp a week from Monday, so if you aren't doing anything, feel free to stop by. We are going to be doing FUN things with our "It's Great to be a Girl" theme like making our own bubble bath, bath salts, flip flops, headscarves, and purses and other things like cooking, watersliding, yoga, songs and games, fishing, and shopping at our trading post. Look for all the girls wearing pink T-shirts. Let me know if you need directions! LOL...See MoreBlast from the past - 2000 'Get to know each other' thread

Comments (208)Emily, Thank you for the wonderful package. I am sorry I didn't post sooner but we were out of town. I love the two vintage books: The Art of Carving and Helen Corbitt's Potluck. I already saw some recipes that I will be making. I love the fantastic seed collection that you sent and will be wintersowing these right away. Thank you also for the yummy treats: Lorna Doone cookies (love these) and yummy Lindor chocolates minus one (my son couldn't wait to try) Toberlone bar- Yum Yum Yum! I also love the tea's Irish breakfast, organic chamomile, english breakfast and Lemon Lane (great name) I look forward to a relaxing cup today after work! Also love the beautiful silver tube key! I have never seen one of those before so I will have to research it and find out more! I love everything Emily! Thank you again! Amy...See MorePKponder TX Z7B
