Query: MAGIC POTION

I use SuperThrive on orchids. The product in conjuction with a non-urea fertilizer make a powerful potion. I have never "lost" a plant since using this product. Flowers stay alive longer on stem after blooming. I also use it in cut flowers purchased at the grocery and in Christmas tree water. A good price is less than $2 an ounce including shipping and tax.
