Seeding a lawn is a cheaper and more versatile option than laying sod. But grass seed can take a considerable amount of time to grow. This not only requires patience, but can become a more significant problem if the seed is planted later than the prescribed date. Grass seed should be allowed time to take root and establish itself before harsh summer or winter temperatures hit. Germinating grass seed with Epsom salts can give grass the boost it. The magnesium in Epsom salts increases germination speed by 300 to 400 percent and germination rates as well.

Place the grass seed in an old pillow case.

Fill your bucket three-quarters full with lukewarm water. Then add the Epsom salts and stir well until the salt is dissolved.

Submerge the seed-filled pillow case in the bucket and allow it to soak for 24 hours.

Remove the pillow case from the salt bath and allow it to drain.

Empty the bucket, rinse it out and refill it with lukewarm, salt-free water. Submerge the pillow case and allow it to soak for another 24 hours.

Remove the pillow case from the bucket and allow it to drain.

Empty the seed from the bag and spread it out in a cool dry place until it dries. Rotate the seed occasionally so it dries evenly.

Spread the seed over the prepared planting area as usual.
