OBF Organic Slow Release Bonsai Fertilizer 4-6-4

OBF is a perfect all round fertilizer for bonsai and almost all other plants. Especially if you are looking for even controlled growth with an emphasis on root development. It is granulated with varying sized small grains which result in slow release over a period of about 4 to 6 weeks. 

Recommended usage is 1 tablespoon for every a 4" x 6" of soil surface every four weeks during the growing season. If you live in a very mild climate, you can apply OBF year round. In cold climates you might want to apply OBF from very early spring up to a little before the ground freezes at the beginning of winter. Because OBF is mild and well balanced, you can experiment with stronger concentration without worry. 

NPK 4-6-4. 10oz (280g)) per bag. 100% organic.
