Your plants and landscape will get the nutrients they need all season long from Jack's ClassiCote with Crystal Green. This time-release fertilizer is now formulated using Crystal Green, a highly pure, crystalline compound with innovative green technology that captures nutrients from wastewater. ClassiCote 15-8-23 feeds your plants in a sustainable earth-friendly way utilizing a renewable, slowly available source of phosphorus and magnesium that would otherwise be lost as waste. The controlled-release nutrients are available to the plant in small increments, giving time for absorption instead of washing away.

This plant fertilizer blend with enhanced micronutrients availability provides four months optimal nutrition for strong roots and vital green growth. The balance of 15% nitrogen, 8% phosphate and 23% potash means an NPK ratio of roughly 3-1-2, which is ideal for lawns as well as many plants, shrubs and non-flowering trees. We offer four-gallon shaker jugs of Jack’s ClassiCote Plant Fertilizer for hobby gardeners and large 25-pound bags for landscaping or commercial growing. Follow the simple instructions or call our sales associates to get answers to any questions about this high-quality plant food.

Fun while they lasted
Color: Green
I ordered two. One for each pup. Both my puppies loved this toy. The first one lasted less than a day with my pup who loves to do the death shake on everything. The second lasted two days with the other as she chews in the same spot. They loved the crinkle noise. However, I'm taking one star away due to not lasting long. Everything else was fine and they enjoyed them while they lasted. Note that most toys do not last long with my pups.

Puppy Loves this toy
Color: Tie Dye Blue
My puppy is a 7wk old Great Pyrenees & Lab mix. He loves this toy! Fun for tug of war and for cuddles. Definitely worth the money. It is durable enough for razor puppy teeth.

The pooch is on Cloud No 9
Color: Blue
Lucky loves everything about this (blue) octopus. It has squeakers in all the right places and the crinkle sound adds to his fun. He’s almost 70lbs and extremely strong, and can be an aggressive player and chewer. So far, it has held up extremely well for the tug-of-war games and crazy shaking play. It’s well worth the money. I also want to mention that this toy is true to size. I have too often ordered dog toys that turned out to be much smaller than advertised.

Cute, soft, quiet and durable
This stuffy is HUGE! I was expecting it to be half this size. We're happy to have a stuffy that does *NOT* have a squeaker. We're finding it to be very sturdy. My 4 month old puppy is a terrier mix and she loves to attack and shake stuffies and you can't tell this thing has been abused at all. Looks the same a 2 weeks later as it did new. It's one of her favorites and we love it because its quiet. Should last a long time. This is an update 4 months after purchase. The red squirrel continues to be a favorite with my puppy. With other plush toys, she tears them apart in 10 minutes. This one, somehow, has lasted months. Over time, she has pulled off the tail, the ears, and two of the legs, but the body is still intact. Amazing!
