What’s new for 2010? Some of your favorite liquid fertilizers under the TigerClaw brand, that’s what. The formulations on some of the products were tweaked slightly and some of the names have changed. If you were using TigerClaw Calcium 4%, it is now called TigerClaw Power-Cal 4%. If you were using the comparable zinc product TigerClaw Zinc 6.5% Zn, this is now named TigerClaw Power-Zn 8%. A new name and stronger, too!
