The appropriate rate of Epsom salt application for wildflowers and grass seeds is sprinkling one cup of Epsom salt on every 100 square feet of lawn and then watering the area to blend it into the soil.
Epsom salt, when used in moderation, can be beneficial for grass. It contains magnesium and sulfur, which are important nutrients for plant growth. However, it's essential not to overdo it. Here are some guidelines:
Epsom salts, also known as magnesium sulfate (MgSO4), is touted as “one of the most perfect nutrients for gardens and plants.” Numerous claims are made to its effectiveness in increasing seed germination, improving uptake of other nutrients, and enhancing growth and overall health.
Lightly sprinkle directly atop the grass
You can dilute Epsom salt with water and use it as a soil drench. On the contrary, you may as well employ a sprinkler system and consider working the salt into the soil without diluting it in water first.
Peat moss is the correct answer. Highway departments use straw because it is cheap and they don't care about weeds, which you will get with straw. If you're going to all the effort of seeding and watering you should do it right and lay a thin topping of peat moss over the seeds. Your new grass will thank you.
Very Small Patchy Areas: For tiny bare spots (think a few inches in diameter), throwing a small amount of seed and keeping the area moist might suffice. However, even in these cases, lightly raking the soil to create some seed-to-soil contact can significantly improve results.
Does Putting Grass Clippings on Bare Spots Help Grass Grow? While leaving grass clippings on the lawn during mowing (grasscycling) can offer benefits like nutrient recycling and improved soil health, it's not the most effective method for directly promoting grass growth in bare spots.
Sulfur is essential for protein synthesis and overall plant development. "When Epsom salt is dissolved in water and applied to the soil, plants can absorb these nutrients through their roots," says DePaola. This leads to improved chlorophyll production, better nutrient uptake, and overall healthier plant growth.
As far as a great natural fertilizer, Compost and composted cow manure are great.
Water and Protect the Grass
After seeding and fertilizing, you'll want to keep the top inch of soil moist until the seeds start to germinate (aka sprout). This means misting the area once a day, maybe twice if it's unusually hot out there—but don't let the area get soggy.
The Epsom Salt protects the grass roots and helps them get stronger in order to resist weather conditions, physical damage or mowing stress. A dilution of water and Epsom Salt sprayed on the lawn monthly will do wonders to the turf.
Baking soda, also known as sodium bicarbonate, can be used as an Epsom salt alternative as well. Baking soda is not only used for therapeutic purposes as well as a remedy for sunburn and itchy skin but also to ease sore muscles by adding into baths.

First Planting with Epsom Salt
Prep garden soil by sprinkling up to one cup of Ultra Epsom Salt per 100 square feet, and then work it into the soil before seeding or planting. This helps the seeds to germinate and start with a strong, healthy growth.
Turfgrass seeds can be soaked in water for 3 to 5 days to germinate. Kentucky Bluegrass (KBG) is slow to germinate and should be soaked for five days.
It's also said to help seeds germinate and repel slugs and other garden pests. But unless your soil has a magnesium deficiency, the University of Minnesota Extension Service recommends against adding Epsom salt. Too much can harm your plants and soil.
Depending on the size of your garden, compile enough of each component to contribute a moderate amount to each hungry plant. Combine the two together, crush the eggshells by hand even more (which should be easier now that they're fully dry), and sprinkle the mixture across the soil bed.
Prevent Fungal Disease
MAKE IT: Mix 1 teaspoon of baking soda and 2-3 drops of liquid soap in 1 liter of water. Spray the solution on the infected plants. Baking soda helps the plants become less acidic and prevents fungal growth.
The key to a healthy lawn is growing it in soil with plenty of organic matter and alive with microorganisms. Apply a thin layer of weed-free compost over the lawn in the spring and in the fall. Water gently to help the nutrients and microbes migrate into the soil.
Late summer or early fall is the best time to overseed lawns. Soil and atmospheric temperatures are most favorable for optimum seed germination and growth. With adequate moisture, fertilizer and sunlight, the new seedlings will be well established before cooler fall weather sets in.
Amend the soil with compost or topsoil to improve soil quality and help new sod or grass seed get off to a good start. Rake and tamp the area so it's level with the surrounding lawn. Use a handheld or push spreader to sow the seeds. Lightly rake them in.
Covering grass seed with mulch is an effective way to prevent it from drying out and becoming rotted. Furthermore, the covering helps warm up the soil and retain moisture levels. Mulches can be used to cover seeded lawns.
Use a shovel or sharp spade to dig out the brown grass — roots and all — cutting out a little beyond the patchy area and into the green grass, and several inches deep. Prepare the area with compost and level. Loosen soil in the patch area with a rake to give the new grass roots a welcome spot to sink into.
Mulching for Seed Protection: After seeding a lawn, a light layer of grass clippings can act as mulch, protecting the seeds from birds, wind, and sunlight.
