Measuring the perfect amount of soil needed to fill a 5-gallon bucket is a bit challenging. Since buckets are usually measured by their sizes, not the amount of soil they can carry.
There is no need to worry cause here, we will provide you with all the necessary calculations you need.
How much soil & dirt do I need to fill a 5 gallon bucket?
On average, a 5-gallon bucket holds about 16 quarts of dry soil and dirt and around .7 cubic feet of soil. A 40-pound bag of soil usually does the work as it can easily fill up a 5-gallon bucket. You should not fill the whole bucket with soil because compost and roots require some space.
Buying the right amount of soil could be a hassle as different manufacturers label their products in other measurements. It is wise to buy a little more than what is required.
Potting soil bags are sold in different sizes range from 6 to 60 quarts and 1.25 to 2 cubic feet. It is better to buy a little more than what is required for sudden mishaps. A 5-gallon bucket of dirt weighs around 36 pounds or .7 cubic feet.
This estimation is based on the average usage of water, the volume required for compost and roots. If your bucket tips over, you can replace spillage with additional soil you have at hand.
The exact amount varies because it depends on the drainage material you use. So, 5-gallon buckets usually hold around 35 to 40 pounds of dry soil or dirt. With a 2 cubic feet bag of soil, you can easily fill up 3 to 4 5-gallon buckets.

Roots can grow adequately in an 8- to 10-inch-deep container. Tomatoes and carrots need a little more space, around 12 inches.
If you’re planting anything other than tomatoes and carrots, you are safe to go with 6-to-8-inch containers.
How long is bagged soil good for?
Soil nutrients, moisture, and texture degrade over time. Whether you open the bag or not, these components of soil will lose quality. It is best to use soil from opened bags within 6 to 12 months.
And for unopened bags, it is best to use the soil within 1 to 2 years. After 2 years, it will lose most of its nutrition, and plants will not benefit from it. But it can serve other purposes.
If you cannot find potting soil in quarts, look for a 40 lb. bag of potting soil. One 40-pound bag of soil and dirt is enough to fill your 5-gallon bucket. Or you can buy a 1 cubic feet bag of soil. Do not worry if you have some left. It might save you from unanticipated events!
