A REMINDER: FOR BOTH THE WELL BEING OF THE FROGS AND YOURSELF YOU ARE COMMITED TO USING ORGANIC METHODS OF GARDENING. THAT MEANS FOR INSTANCE USING ORGANIC COMPOST, NOT USING TOXIC SLUG PELLETS (usually Metaldehyde or methiocarb) OR CHEMICAL PLANT FOOD OR WEED KILLERS . YOU CAN FOR INSTANCE USE A LIQUID SEAWEED PLANT FOOD SO LONG AS YOU DILUTE IT CORRECTLY.
