All Purpose 10-10-10

[nnjjohn]

Okay, previous seasons , I neglected amending my beds thinking the stable mix alone would suffice.. also relyng on liquid 15-30-15 the sugary looking blue stuff that you mix one teaspoon per gallon and water around the plants.. little did I know it wasn;t enough and my plants produced but not many as I would have thought. Certainly not like some of the tomato beds I've seen the same season in my region. So the weather is ruled out. QUESTION: If it is recommended as an amendment,,and only if it is a good idea and not risky.. how does one use All Purpose 10-10-10 granular fetiliizer? I know it can burn roots but what if I distribute say a coffee can over 10x10=100sq ft one month before planting? After several rains it should makes its way down into the soil.. shouldn't this be the way to amend a garden bed? tia,
