Do not overfertilize. Excess fertilizer applied to lawns and gardens washes off and pollutes streams. Because they contain nutrients such as nitrogen, phosphorus and potassium applied in excess, these nutrients nourish weed growth and algae in our lakes, rivers and steams. Learn what grass really needs in order to grow.

Why not consider using something nontoxic on your lawn and garden? Try companion planting, for example:

  • Lettuce and garlic
  • Potatoes and shallots

For information on using non-toxic or least toxic means of controlling pests call Cornell Cooperative Extension, Westchester Division, (914) 285-4640 between the hours of 9 a.m. - 12 noon. The horticulturalist will try to answer your questions regarding pest control, soil conditions and other gardening problems.
