The best micronutrient supplement for plants! I use with potted houseplants

Shweet PotatoNovember 5, 2018✓ Verified purchase

I was first introduced to Flourish when I had planted aquaria. I strongly believed it helped me grow strong, healthy, beautiful aquatic plants which even became a side business where I sold my clippings and extra propogates online all across the country. I no longer have aquariums but have dozens of terrestrial houseplants in pots. I had been giving them fertilizer, but those did not contain micronutrients other than iron. The result was that the new growth was not as pretty as it could have been. In particular, the leaves of my peace lilies were paler between the veins in some type of chlorosis. I remembered that Flourish had brought out the best in my aquatic plants, so ordered this for my potted plants. I am dosing at a concentration of about 10X what it says on the bottle (I add ~1mL Flourish / gallon water) because the houseplants are not constantly bathed in a nutrient-rich medium of water. I assumed that by giving this to only the roots, the plant would still be able to absorb and transport the micronutrients to the rest of the tissues. A few drops into my 0.4 gal watering can every other week did not seem excessive to me. Well, it worked. My peace lilies no longer have chlorosis and all my other plants are healthy as can be. See pictures. I use Flourish on all my plants - including tropicals, succulents, epiphytes such as orchid, and even herbs ( basil, mint, and scallions) to be eaten. None have reacted badly and all are... "Flourishing"! I truly believe this product has played a part in bringing my plants from just surviving and growing into thriving and being their very best!!! It contains the widest range of micronutrients I have found so far. Read more
