Weight of bark chips
Hi, Does anyone know how much bark weighs?
We have 2 suppliers locally - one sells by cubic metre, the other by the ton. Without a conversion figure it is like trying to compare apples and oranges and since I need about 12 cu metres a small difference could make a big impact on my pocket :-)) -- Sue Remove the puppies to reply |

The mix of sizes is important too. The small bits can fill in the gaps between the larger bits. Whether they sell it wet or dry will make a big difference too - with weight you'll end up paying for the water. I'd expect dry wood chips to float so 1 cubic metre would weigh less than a tonne - Google turned up ratios of between 0.25 and 0.75 so there is a big range but take the middle of 2 cubic metres = 1 tonne and you won't be far off. -- Martin & Anna Sykes ( Remove x's when replying ) http://www.users.globalnet.co.uk/~sykesm |

[which seems awfully heavy for what is after all, just over a 6ft cube of chipped bark ] But then 1 cubic metre of water weighs 1 tone so a 6ft cube of water would weight about 5.8 tonnes. -- Martin & Anna Sykes ( Remove x's when replying ) http://www.users.globalnet.co.uk/~sykesm |

Googling "chipped bark" and "bulk density" gives the following figures in the text preamble to the first link on the page. The actual link is of no use, simply leading to an Ask.Jeeves listing of chipped bark suppliers in Scotland. quote The bulk density of chipped bark is low (150 - 250 g/ltr) The density of most woodchip products is in this range. Allow 4 Cu m per tonne and you won't be far out Of course the density changes daily according to conditions, so what they do at ECO is a test weighing each morning to ascertain the density that day. It's mostly sold by the metree, but the vehicles are weighed out and charged by weight so you need the conversion figure for that day. [which seems awfully heavy for what is after all, just over a 6ft cube of chipped bark ] That's because a 6ft cube = 6.12 Cu m, not 12. Steve |

Many suppliers use the 'ton' as a measure of volume rather than weight. If they fill a ten ton truck level then they often call that ten tons; whereas the actual weight would be very much less. For true weight a weighbridge would need to be involved; which is most unlikely. Best Wishes Brian. |

Yes I do agree with you and in a couple of years it will be, but it is a garden in its first year. The bed is about 35m x 4m and already has over 300 assorted shrubs and perennials in it. (It is probably overplanted really) but at the moment it has enormous amounts of bare earth and because the ground has never been garden before, I am getting the last 50 years accumulated seeds all seeing daylight and germinating. In the space of a couple of weeks it has sprouted a fine crop of rape seed :-(( The bark is the only thing I can think of to keep me sane while waiting for the plants to spread and cover it. I don't want to put anything too permanent on as I know I will have to move, divide and swap plants around once they really start to grow. -- Sue Remove the puppies to reply |

Do you want the bark chips just for mulching or is visual appeal a factor. It seems to me that you would save a bundle by getting contract mulch rather than bark chips. What part of the country are you in by the way? Steve |

What part of the country are you in by the way? Steve I'm 30 miles north of Aberdeen. The visual appeal is a very temporary thing as I hope by next summer (or certainly the summer after) there won't be any bare ground showing. I tend to like wild and woolly cottage style beds :-)) All I need really is something that won't become a pest in the future -therefore anything stony is out. I have used broken slate on another bed and have found it a nuisance when moving plants as it is quite difficult to clear a patch and not end up burying any. -- Sue Remove the puppies to reply |

But anyway, for the purposes you describe, I would suggest contract mulch, the basic mulch, the stuff the builders use between the shrubs at supermarket sites etc. I don't know your local suppliers, but if you check out ecocomposting, they have pictures, specifications etc to help you choose.

The stuff I have bought had been hydraulically compressed into bales without any obvious voids and was very dense. It expanded to about 3x the volume of loose bark chippings. Compacted they are probably going to weight in at just under 1T /m^3. Wood floats on water but depending on how wet they are not by very much. Loose it could be anything as you say depending on the shapes. Regards, Martin Brown |
