Well I certainly stirred up the hornets nest with Super-Thrive. I do know about what it's made from and who could possibly be contained in it. The original creator has past away so I have no idea if whoever took it over is still using the same formula. I usually don't use it as a fertilizer enhancer because it contains extra nitrogen and phosphorus, which on some plants does cause problems such as orchids. I've never used it on full grown orchids but I have used it on baby plants and it does give it a little extra boost. Just a drop of the ST in a quart of water and then put it in a spray bottle and spritz. Lately the one place that I do go to when I can get out there has been getting organic ferts in different strengths as well as worm castings and bat guano, all of which could be used on our potted friends, within reason. Not all plants can handle large quantities of fert. My Brug's and Iochroma will and the Alocasia's and Colocasia's will. Tomatoes and peppers and cucumbers can always use a little extra. Since most large watering cans are about 1.5 gals, you can use one scoop plus one from the little scoop at the other end on the veggies. Corn you don't have to, or peas or beans because they fix nitrogen and don't need the extra.
I have a picture I'd like to share with you all and anyone looking. If you don't know what rust looks like this will show you. This is on my Lavatera which is in the Malvae family (Hollyhocks). They like all in that family are very suceptible to rust. Thankfully, it hit at the end of the blooming phase so now I can cut it down to the ground and wait and see if it comes up from the ground again. I have seed, lots and lots and lots off seed to save if I want to, to start another one next year. The picture will show a leaf on the left that has yellowing and the one on the right shows the fruiting bodies that are rust colored. There is nothing you can spray or do to keep it at bay. Just make sure you clean up all debries and put it in the garbage and not the compost pile as the spores will be in there. So my little bit of information for today.
Again thanks for all the help and I'm keeping a eye on my little children.
Good growing to you all.
