We are happy to announce that after several years we carry the 1 lb tub of the award winning Optimara Plant Food 20-5-10 again! Each tub holds one full pound of Optimara fertilizer for green plants and comes with an easy-to-use measuring spoon. This premium quality green plant food contains high grade trace elements and is urea-free. It can also be spray-misted on foliage. 1/2 tsp. per gallon will yield 1 gallon of fertilizer.
