All Golfgreen Grass Seed products are considered 'Apply & Play' products. This simply means that it's best to keep other people, children and pets of the area while you are applying it to a dry lawn. Be sure to achieve the recommended coverage, and always apply it with a spreader. Once applied it will be completely safe for all to return to the area. That being said, as this product contains a grass seed it is essential that all traffic on the seeded area be kept to an absolute minimum. This will allow the seeds to germinate and establish themselves. With constant disturbance it will void the seedlings as they begin to germinate , thus giving you less than ideal results, if any.
