The Garden Club of Kent, Ohio May 31, 2017
The Garden Club of Kent would like to thank Osmocote for their support of our growing efforts. We use Osmocote both in our Greenhouse and at home. Hereby, we offer some testimonials from Garden Club members about Osmocote: John M I use Osmocote in my garden. I put a teaspoon in with each plant. One plant grew 9 feet tall - over the fence and into the hemlocks! I use it on my rhubarb and, over the years, have split off at least 100 other plants. I use it in my hanging baskets and they last till fall. It really does work! Ron S (Certified Horticultural Judge) My wife and I are nurturing baskets of double, white mini petunias, yellow and white lantana, and bridal veil for my granddaughter’s wedding in June. I treated each basket with Osmocote when I bought them and will give them another feed in June. I know that the baskets will be lush and beautiful for the wedding because Osmocote works. Bonnie Z (Certified Horticultural Judge) I grow a lot in planters. I put Osmocote into each planter when I plant and again in August and I always have very good luck. Osmocote doesn’t brown the plants. I LOVE it! Steve S I use Osmocote in my personal vegetable garden, on the peppers and tomatoes, especially. Also, the Garden Club adds it to the potting soil we use in our greenhouse where we grow our many hundreds of plants for the sale we hold every year. Our customers eagerly await our Annual Plant Sale because, they say, “Our plants are the best around!” Sue A (Graduate Horticulturist) I always use Osmocote on my peppers and tomatoes. Judy W I have many house plants, including 9 fuchsias, a kumquat tree, key lime trees, and a 44 year old lemon tree. I winter all my plants in an unheated bedroom and on a sunporch. In the spring I feed them with Osmocote to give them a good start for the summer.

Best Fertilizer on the market April 23, 2017
I have been using Osmocote since I became resident of Young Harris, Georgia in 2008. This product is very easy to use and gives fantastic results for all of my garden plants. I highly recommend Osmacote. I appreciate that samples were sent to The Enotah Garden Club to share with those that came to our Plant Sale.

Master Gardener, Plant sale chair, greenhouse worker March 31, 2017
I use the Flower and Vegetable Osmocote because it is a quality balanced NPK. However, the greenhouse I work for was out of that particular product so instead of switching to another brand, I purchased the Outdoor and Indoor Osmocote. I used it on my house plants and they responding immediately like they were suddenly awaken from a long sleep! So then I applied it to some of my garden plants that like more nitrogen and wow. Love it! Love the convenience. will always have both products in my shed.

A container garden must have! March 28, 2017
Since I have started using Osmocote in my container gardens, my flowers stay looking incredible all season. The fertilizer gives them the long term boost they need to remain fresh and flowering all summer. I add Osmocote to the planting holes and then sprinkle a little on top of the soil around the plants. It cannot get any easier than that! I also add Osmocote to the planting holes of my perennials to give them a boost to transition to their permanent homes in my flower beds. The measuring is easy, the fertilizer works well, and there is no mess or smell. I consider Osmocote a gardening must have!
