Does pulling crabgrass spread seeds?
Pull out young crabgrass first. Less of a hole is left for the weed seeds to fill in when the younger weeds are present. Mature crabgrass contains forked seed heads holding thousands of tiny seeds that will scatter on the newly dug hole. Second, use a shovel to scoop out the weeds from the bottom of the hole and place them in a plastic bag.
Place the bag in the sink and fill it with water. Let it sit for a day or two to allow the water to evaporate and the soil to dry out. This will help prevent the seeds from germinating. If you don’t have a sink, you can fill a bucket with clean water and pour it into the bucket.
You can also place the bags in an airtight container and let them sit out in direct sunlight for several days. After a couple of days, they will begin to sprout and you will be able to see the sprouting seeds.

However, if it looks healthy and is growing well, you may want to consider treating it. The best time to do this is in the spring or early summer, when it is most likely to be growing.
