Length x width x 3/12 divided by 3. Does that sound right for 3 inches of mulch?

3" is overkill in my opinion, unless they specifically asked for it.

You need to put down atleast 3" in a new bed. If you're topdressing, 1-2" is fine. If you put down less than 3" you'll just be back next year doin it again. Most people up here want 3".

Oh, well that's exactly why I do it. This = more $. This is also why I spray my roundup to last a month, so I keep getting paid.

I go about 1.5-2" unless the customer specifically wants otherwise :walking:

I have 3 so I don't end up short, and most of her flower beds are bare. I spray round up every week when I mow at a couple of places, if I see a weed, I spray it. Is my formula right though? I don't want to screw up. Preen works really well too.

Ok, find the area... So lets say its 20x10, and they want it 2" thick...

Well, you need the volume... And 2" is 2/12 of a foot or 1/6= .16

20 take your area (200 sq ft) and multiply by thickness (.16)... 200x .16= 32

So thats 32 cu ft, but they sell bulk mulch by the cu yd whic is 3x3x3 ft...

So thats 27 cu ft per yd...

You would need 1.18 yds and i add in 10% for error... so 1.18x 1.1= 1.298 yds...

Thicknesses Guide ... (The number you multiply by your sq ft, then divide by 27)

1"= 0.83 ft

2"= 0.16 ft

3"= 0.25 ft

4"= 0.33 ft

no feet are cubed too , thats why .25 represents 1/4 of a cubic ft= 3 inches.

ok, ya. I was thinking square foot, but ya. Once you time by the 1/4 ft you get cubed. So you divide each thing you multiply by 3 which would be 27. I get it now. I am glad I asked and not end up with 3 times the mulch I needed. lol!

If you don't feel like figuring the formula out, there is a mulch calculator on this site. Upper left corner of the page, click on the helpful tools link.

That's all fine and dandy but, everyone has their own method. Personally, I've found that 3" is perfect for proper water retention and a thicker layer also helps suppress the weeds better. Plus, we get 140 yds. of mulch at a time, with our markup we're making $22.00 a yd. So that's another reason we use 3" right away, you're never guaranteed they're gonna call you back, might as well lay it thick the first time.

4 inches is 1/3 of a foot which is .33 in a decimal

1 inch is 1/12 of a foot so it is .083 not .83..he forgot the 0

If I am going to be spreading where the depth will be in inches [say mulch] then I use this formula.

lengh in feet X width in feet X depth in INCHES / 324

This way you do not have to divide lets say 5"/12 which would be .41666666

Length x width x 3/12 divided by 3. Is that right or wrong, that is what I am asking. I have not got a yes or no on it.

JC...Here's the easiest way to figure how much mulch.

length (ft) x width (ft) / 324 x depth (inches) = yards needed

i.e.

a mulch bed that 4ft wide & 100ft long and you're going to add a 2" toping layer figures out:

4 x 100 = 400sq ft

400 / 324 = 1.23

1.23 x 2" = 2.47

rounded = 2.5 yards of mulch

I have this written inside my folder. Never leave home without it. Good luck!
