Plant Clinic is Open:
Over the course of the last few growing seasons, the Plant Clinic at the Missoula County Extension office has seen a number of garden samples with symptoms similar to those consistent of herbicide exposure. Growth regulator type herbicides that are commonly used in turgrass settings target broadleaf weeds, while generally leaving the grass species unharmed. Quite often there can be residual effects in the garden when grass clippings (sprayed with these materials) are added directly to the garden or to the compost pile that is subsequently used to ammend the garden soil. Characteristic symptoms of growth regulator type herbicides are cuppoing of leaves, stunted growth, and twisting of growing points. Below is a booklet diiscussing some precautions when using grass clippings, compost, and even manure in your garden.
