To determine the correct amounts of mulch for your garden, you must performs a calculation based off the area of the garden and the depth of the mulch that you want in your garden. Mulch serve several functions within the garden. Mulch helps to suppress the weeds that can growing in your garden.
Mulch helps to retain the moisture that is present in the soil. Mulch help to gradually add nutrients to the soil as the mulch decompose in the soil. If you use too little mulch, the weeds may grow up through teh mulch.
How Much Mulch Do I Need
If you use too much mulch, the mulch may choke the roots of the plants in your garden. Therefore, you must decide on the depth of the mulch before you go into the store to purchase the mulch for your garden. The volume of mulch are measured in cubic yards and cubic feet.
One cubic yard is equal to 27 cubic feet. One cubic yard of mulch spread two inches deep will cover 135 square feet. One cubic yard of mulch spread three inches deep will cover 108 square feet.
One cubic yard of mulch spread four inches deep will cover 81 square feet. Therefore, the deeper you spread the mulch, the less mulch will spread over the area of your garden. You can control the amount of mulch that spreads over your garden by choosing the depth of the mulch layer.
To calculate the amount of mulch needed, you must first calculate the area of the garden that will receive the mulch. To find the area of a rectangle, you must multiply the length of the rectangle by the width of the rectangle. To find the area of a circle, you must use the formula pi times the radius to the power of two.
For irregularly shaped gardens, divide the area into several shapes so that you can calculates the area of each section. Once you have calculated the area of the garden, you can calculate how much mulch you need to cover the garden bed. The type of mulch that you purchase will affect the total weight of the mulch that you purchase.
Hardwood bark mulch weigh between 400 and 600 pounds per cubic yard. Cedar mulch weigh between 350 and 500 pounds per cubic yard. Pine straw mulch is the lightest at between 200 and 300 pounds per cubic yard.
Rubber mulch is the heaviest at more than 1,000 pounds per cubic yard. The weight is important to consider if you are transporting the mulch to your garden with a vehicle. You can purchase mulch in bags or in bulk.
Mulch is typically sold in bags that contains three cubic feet of mulch. If you purchase mulch in bags, you will find that bags of mulch are more expensive than bulk mulch when buying enough mulch to fill an entire garden. One cubic yard of mulch is equal to nine bags of mulch if each bag contain three cubic feet of mulch.
Bulk mulch is less expensive per unit but requires a way to transport the bulk mulch to your garden. Additionally, mulch will compact over time so buying a little extra mulch will allow the mulch to settle into the soil without creating a mulch mound at the edges of your garden beds. To apply mulch to your garden, you should first measure the area of your garden.
Then, you should decide on the depth of the mulch that you would like in your garden. Next, calculate how much mulch you need to spread even over your garden beds. When you spread the mulch, rake it evenly to form a level mulch area.
Finally, refresh your mulch every one to two years as the mulch decomposes over time. If you follows these steps, you will be able to ensure that your garden has the correct amount of mulch.
