Lesson learned to use only trusted brands

I have been using various fertilizer products for over 35 years and this by far has been the worst product I have used. I applied the product exactly as described and after application...several areas of what use to be lush green fescue, is now stunted and stressed out grass. The reaction is very similar to using a herbicide that stunts vegetation growth. Will never purchase this product again.

No instructions for using a drop spreader, that is says it works with.

reply from Pennington Team

You can apply Member’s Mark Southern Weed & Feed 12M using a drop spreader by distributing the granules evenly over the lawn at the recommended rate listed on the bag. Apply the product when weeds are actively growing and the grass is slightly damp from morning dew or light watering, as this helps the granules adhere to weed leaves for better control. Fill the spreader on a hard surface to avoid accidental over-application on the lawn, then walk at a steady pace in straight, overlapping passes so the spreader’s wheel tracks guide the next row and ensure even coverage. Because a drop spreader releases product directly beneath the hopper in a narrow path, it is important to avoid gaps or double applications. After applying the product, avoid watering the lawn for about 24 hours so the weed control ingredients can work effectively on the weeds. If you have any questions, please give us a call at 1-800-285-7333.

This weed and feed does not work. do not waste your money. I have used Scott's every year except this year when I purchased the members' mark weed and feed. This stuff is junk.

This will not dissolve quickly, the active for weed killing will come off onto the weed leaves and start working , and the controlled release fertilizer will dissolve over time while feeding your lawn, Our customer service is 800-785-7333 please contact them and they will help you. Thanks
