ORGANIC FOODS FOR YOUR PLANTS
Where to Feed, With an Exception
To get the most out of any organic fertilizer, keep in mind how plants feed and how these fertilizers act in the soil. The bulk of plants’ feeder roots — whether the plants are midget marigolds or mighty oaks — lie just beneath the surface, so generally there is no need to dig fertilizer deep into the soil. And anyway, low oxygen levels there would retard the microbial growth necessary to unlock nutrients from most organic fertilizers.
