How To Grow Grass On Hard Clay Soil
Clay soil can be challenging to deal with, especially when it comes to planting grass. Everything from planting to watering the grass tends to be problematic compared to other soils.
However, if you follow the mild steps sketched below, you should have no problem growing grass that will survive all seasons.
Step 1: Before planting, start by testing the soil density- make a small ball using soil and water, then press it, and if it splits at 1 or 2 inches, you have clay loam soil. But if it makes a ribbon that is longer than 2 inches, you have harder clay.
Step 2: Add organic compost clay soil, roughly 6 to 8 inches, for heavier clay soil. Mix it to improve the organic matter, then let the soil settle for two or more months.
Step 3: Retest the soil density again. If you did a good job, it shouldnt form long ribbons. Repeat step 2 if it does until you get the desired results.
Step 4: Plant your grass seeds, and dont forget to plant grass plugs to ease air circulation.
Step 5: Lastly, wet the area with water. It will help if you use a sprinkler to distribute water evenly.
Will Grass Grow On Hard Soil

Buying Good Soil To Cover Up Hard Dirt
Topsoil in our area is about $40 a yard. Our pickup truck bed can hold about a yard, so you can think of the dirt price as $40 per pickup truck full of soil. We started with one pickup truck and it went so well, we decided to do the whole yard.
We ordered a total of 20 yards of topsoil for both the backyard and front yard. The topsoil came in 2 dump truck loads. Including delivery and taxes, the bulk order was about $900. It was enough to bury the clay in 6-8 of topsoil. We watered and levelled the lawn area a few times to let the air pockets settle out, and then it was smooth sailing to turf town.
If youre thinking of doing something similar, consider measuring your yard before you order. Also, be sure that you can change the grade of your property like that. You may only need to do a small area. Only do what you need to do! And be sure to source your mined topsoil from a sustainable producer.
How To Soften Hard Soil By Adding Gypsum
Gypsum is a natural mineral that is found in many everyday items, like toothpaste, shampoo, and potting soil. Have you wondered what those small white pieces are that look like bits of Styrofoam in potting soil? That is gypsum and is chemically known as calcium sulfate hydrate. That stuff will soften hard soil by absorbing and holding moisture, which will prevent the soil from being compacted. Chemically, it will also reduce the amount of salt in the soil and increase the calcium level.
Gardeners sometimes increase the amount of fertilizer used on hard soil in an attempt to grow vegetation. The extra fertilizer does little good too soften the soil since it does not address the real issue of hard soil. However, all that fertilizer does leave behind an excessive amount of salt in the soil and an application of gypsum will reduce the salt content in the soil.
Gypsum helps heavy clay soils by binding with the clay and preventing it from cracking and developing a hard crust on top. When clay soil becomes wet from rain then sits under the hot sun after the rain, it hardens like bricks in an oven. Gypsum will keep the clay soil soft and pliable even when its fully exposed to the sun.
A good rule of thumb is to mix 20-30 pounds of gypsum for every 1,000 feet of garden soil. Gypsum is spread with a hand-held spreader and will remain in the soil for a few years. Work the gypsum into the soil about ten inches deep with a turning fork.

How Do I Prevent Compacted Soil
As with many home improvement issues, an ounce of soil compaction prevention is worth a pound of expensive roto-tilling cure. Aerating your lawn regularly should be part of your lawn maintenance plan and will keep the top layer of soil loose, so your grass will get plenty of water.
Normally, you shouldnt have any issues with deeper soil compaction. If you do need to have a major landscaping project done, like having a pool filled in or building a retaining wall, make sure your landscaper is licensed and insured. Any competent landscaper will do their best to prevent soil compaction, but even the best professionals make mistakes. If they do, you want to make sure theyve got your back.

Using Lawn Sand On Clay Lawns
Sand is not the best option for topdressing your lawn. It should only be used to fix heavy thatch build-up, cover exposed tree roots or level low areas.
Applying sand can cause your lawn to lose its fertility. Sand particles do not retain any nutrients and minerals, so it is better to use fine compost instead.
Another common mistake that many gardeners make is applying sand too heavily, which leads to the death of grass. Besides, many homeowners also make the mistake of using sand to fix clay soil.
However, you should not do that, as adding sand to such soil often creates a cement-like effect, instead of loosening it up.

How To Break Up Compacted Soil
Regularly spreading organic matter over the soil surface is the best long-term solution to soil compaction. Organic matter includes compost, shredded leaf mulch, wood chips, straw and chopped leaves. Apply a 3- to 4-inch layer of compost or a layer of wood chips or shredded leaf mulch 2 to 3 inches deep over bare soil in flower beds. Without any further help, soil organisms will incorporate the organic matter and begin to open up the soil. If youd like to quickly break up a hard soil surface for planting, mix the organic matter into the top 3 to 6 inches of soil with a spade. To help soften hard soil in a vegetable garden, add a 2-inch layer of compost twice a year and mix it into the top 2 inches of soil. If the soil in your garden or vegetable patch is bare over winter, spread a layer of mulch over it to protect it from heavy rainfall.
Although it can be tempting to run a rototiller over hard soil, excessive tillage can actually make the problem worse by destroying organic matter.

Soil compaction reduces pore space and increases soil bulk density.
Soil particles stack tighter with compaction.
Pulling soil cores out will soften and aerate soil.
Really want to know why gypsum doesnt work here? In arid parts of the country, sodium occupies many of the cation exchange sites in the soil. And since it is only a +1 charge, soil colloids tend to disperse and can be easily compacted together causing a poor soil structure. Adding gypsum allows the Ca++ to release and replace the soil-bound Na+. The released Na+ is leached out as Na2SO4, and the soil tends to granulate due to flocculation with more Ca++ on the exchange sites. This granulated condition improves soil structure, and soil is then less prone to compaction. Since there is far more calcium than sodium on exchange sites in our Louisiana soils, adding calcium via gypsum has little or no effect on most of our soils.

Will Grass Grow Through Topsoil
Most types of grass can grow through 2-3 inches of topsoil placed on top of it if the existing established plants are healthy. Grass often grows through topsoil when a thinner layer of topsoil is placed on top of an old lawn. Some of the grass do survive the topsoil blanket and manage to push up through the dirt.
For this reason, its best to get rid of the weeds on an old lawn if the plan is to bring in a few inches of new topsoil. If the lawn is being renovated, and youre here reading an article about growing grass on hard dirt, then there are likely a few weeds to deal with. Pull them out before placing the topsoil.

Does Soapy Water Hurt Grass
Yes, in concentrated form, dish soap will kill grass. Grease and food can be removed from the surface of the food with the help of dish soap or dishwashing liquid.
Dish soap can be used to clean the inside of a food processor, but it is not recommended for use on the outside of food processors. It is also not a good idea to use dishwasher detergent on food that has been stored in the refrigerator for a long period of time.

Dealing With Desire Paths And Shortcuts
Maybe your lawn sees consistent traffic in a consistent spot, like a shortcut to the bus stop for neighborhood kids.
That unsanctioned route can become a path of bare dirt thanks to the added stress and compaction, called a desire path. Those trails happen where pedestrians find the easiest route from A to B regardless of sidewalks.
But you have options even if that desire path ends up in an undesirable place like your lawn.
Trees and shrubs can direct traffic. Ornamental shrubs or trees can take the place of fences. You may want to go ahead and make it permanent with pavers, mulch or wood chips.
If thats out of the question, compaction problems can be mitigated. Add some coarse sands or other materials like calcined clay where that traffic occurs.
Your lawn itself can also help stop compaction.
Cutting higher and dethatching turf can help absorb some of the pressure and keep it from compacting the soil.
