Hello Kathy,

I can't recommend or endorse fertilizers for your lawn. I did provide you with information from five (5) research-based/university organizations

Applying more fertilizer or other products than the instructions indicate may harm your pets as the grass may hold the residue for an extended period. Pets pick up the residue on their fur and paws and may quickly ingest them.

Fertilizers and insecticides. Properly use and store fertilizers and insecticides. Store them in secure, labeled containers. Always read the label thoroughly before using them. Keep your pets out of the garden for the designated amount of time after applying chemicals. Use safer alternatives: fertilize with worm castings or fish fertilizer; control aphids and spider mites with a strong spray of water or with an application of horticultural oil. Hoe and pull weeds as they appear to reduce the need for herbicides.

Sometimes homeowners use chemicals to help plants grow, control Japanese beetles, kill dandelions, or stop rose diseases. The best way to protect your pets from lawn and garden chemicals is to read and follow all label directions. This includes all fertilizers and pesticides, such as insecticides and weed killers. First, be sure the product is labeled for the location where it will be used. For example, lawn products often cannot legally be used in food gardens. Second, read the precautionary statements to see if the product is toxic to animals. In particular, check to see if there is a time period when pets should not enter the area after application (also called reentry interval). If no interval is listed, keep pets and people out of the area until the sprays have dried or the dust has settled. Third, follow all directions for use. Do not use more products than directed on the label. Finally, store and dispose of chemical products properly. A locked cabinet or room is best to avoid accidental pet exposure.

Fertilizers, pesticides, and insecticides can all be potentially fatal to your pets. Storage of these chemicals should be up on a high shelf with lids tightly secured. The best precaution for these chemicals and others is to read the label entirely and consult with your veterinarian, or the chemical company with concerns. Rain can affect how the chemicals are absorbed into the soil so take extra precautions if heavy rain follows a chemical application. Compost, fish emulsion, kelp, and worm castings are safer alternatives to chemical fertilizers. While safer, these products may have an odor that your dog finds appealing. Watch your pets after applying anything new to your yard. They may eat or roll in something that they think smells good. Compost bin lids should also be tightly fastened. While these safer alternatives may not be toxic, many things may upset a dog’s stomach and if you’ve smelled fish emulsion you know enough to not allow your dog to roll in it!
