The forecast should be clear for at least 24 hours for weed and feed to work correctly. You are also going to need to avoid watering your lawn during this period. Do not try to apply the product immediately after a heavy rain, either. Standing water in your lawn could wash away the particles.
If you do not already own a spreader, you can buy one at a home and garden store or online for under $30 USD.
If a pet or child ingests any weed and feed, call a vet or a doctor immediately to get recommendations for treatment options.
