I have a 7,800 sq. ft. area that needs to be mulched. How many cubic yards of mulch would i need for 1 inch thick? 1.5 inches thick? and 2 inches thick. Thanks for your help.

For mulch I figure in tenths of a foot<br>.1= 1.2&quot;<br>.2= 2.4&quot;<br>.3= 3.6&quot;<br>.4= 4.8&quot;<br>use this figure and multiply by sq. ft. and divide by 27 (this is Cubic feet per Cubic yard)<p>----------<br>paul<br>

Just did a 9000 sq foot bid last night. Job also consisted of around 900 ft of edging. I figured it to be in the neighborhood of 40-45 yards at 2 inches. I subtracted some because a few sections heavily planted. Don't forget that! A lot of plants means a lot less mulch, especially if all ground covers(just sprinkle on around them)<p>I priced it out at around 2300. All on a steep hill. Therefore, my price was steep. I really didn't want the job. Someone else out bid me by about 500 or maybe even more. Got one or those &quot;Wow, we thought the other guy wanted a lot&quot; reactions. OH Well! <p>Pushing wheel barrels up a hill all day and edging ground thats concrete didn't sound like fun to me anyways!<p>steveair<p>

Another way to figure this mulch amount is: Divide square footage by 150. This yields a generous figure that is the number of cubic yards needed. If figuring very closely, use the slightly higher number of 160 to determine cubic yardage for 2&quot; thick.<p>----------<br>Lanelle<br>

I've plinked around with formulas for a few years & my best & easiest one that works well is this: 1 cu. yd. of mulch will cover 125 sq. ft. at an ideal depth of 2 & 2/3 inches deep. Good depth for first mulching, or re-mulching over the bare ground. If you're just covering last year's mulch, 1 cu. yd. will cover about 150-175 sq.ft. Good luck.<p>----------<br>Smitty ô¿ô<br>

7,800 sq. ft. <p>@ 1&quot; thick = about 24 or 24.5 cu.yds.<br>@ 1.5&quot; thick = about 36 or 36.5 cu.yds.<br>@ 2&quot; thick = about 48.5 cu.yds.<p>correct me if i'm wrong, but please check this website first. This is how I came up with these numbers.<p>&quot;Volume and Cost Calculator&quot; http://www.sierra.com/sierrahome/gardening/calculators/
