Organic growbags
I bought some "organic" growbags from a well known DIY chain (I won't name
it, but the sort of place you might buy a BarbeQue). I didn't specifically want organic, but it was all they had and it was the same price as the normal bags. It seems similar to the wood chippings you can buy as a mulch, except that the growbag is ground a bit finer, and has been rotted down a little bit. The problem is, like the wood chips, the growbags have a very strong, characteristic smell, which seems to me like creosote or similar. Now that may be all well and good for a flower bed mulch, but I don't really fancy growing tomatoes in it and eating them! Has anyone else used these grow bags, what do you think? You cannot miss the smell, am I mistaken in thinking it is wood preservative? The growbag claims to have no chemical additives, but what does that mean? If the raw material is creosote treated wood chips, maybe they can get away with saying they haven't added any chemicals. |

I've got a couple of these bags - I'm quite happy to say I bought them at B&Q. I wasn't that impressed with the quality of the product on sight - as you say, it looks like so much chipped wood - but I duly wetted the bags down and planted toms in them, and a week later everything seems to be fine ( so far ). As to the preservative query, I noted ( I think ) a HDRA logo on the bag - or at least an endorsement - so I think it highly unlikely that there's anything untoward in the contents. I very much doubt they're made with creosoted wood chips...it's not really the sort of thing you'd want to get near plants. If in doubt, ask 'em.

I agree with Stephen Howard that it is most unlikely that B&Q would sell growbags as organic if they contain creosote treated wood chips, because creosote is banned for use in organic horticulture. All substances can have a chemical analysis denoting the elements they contain, but 'chemical' in the context of organic gardening means manufactured or processed fertilisers, insecticides, herbicides, fungicides and the like. Organic growbags should contain none of those. -- Alan & Joan Gould - North Lincs. |

You tend to get the latter in composted bark and twiglets from commercial forestry. The smell is strongest when the heaps first heat up and start to steam. Has anyone else used these grow bags, what do you think? You cannot miss the smell, am I mistaken in thinking it is wood preservative? I haven't smelt one this year, but my guess is based on living near forests where the stuff (or something similar is produced).

The Henry Doublespeak organisation exists mainly to help the Organic(TM) industry and supermarkets to fleece the worried well. It is highly unlikely that there are any bad *synthetic* chemicals in a product that they endorse, but natural toxins are plentiful in the environment. I very much doubt they're made with creosoted wood chips...it's not really the sort of thing you'd want to get near plants. Creosote would kill most plant roots. Wintergreen or methyl salicylate in high concentrations will not do them all that much much good either. You can smell it in pretty low concentrations so it should be OK. Regards, Martin Brown |

TIA I'll have a another peek. I really only glanced at it as I was manhandling the bags into the greenhouse.

Not sure exactly what the smell is - it is similar to the smell of the bark/wood chippings you can buy, and also similar to the smell of treated fence panels. In the case of wood chippings, I had always assumed that they had been treated to prevent them from rotting too quickly when applied to the ground. That is why I was disturbed to get the same smell from a growbag. Just to clarify, oil of wintergreen - are you saying that this occurs naturally in composted bark? |

Organic growbags should contain none of those. No dispute that it *shouldn't* contain any of these nasties. Organic salmon *shouldn't* contain traces of banned green dye. Things go wrong even with food, and I suspect second order risks (such as growing materials) get less attention than actual foodstuffs. I am not sure whether organic actually means anything when applied to growbags (I know what it ought to mean, but does it?). I can see the appeal to the manufacturer of using forest by-products (all the right marketing buzzwords, and, despite using cheaper raw materials, if you can charge the same price as a normal growbag everyon thinks it is a bargain). What I am not sure about is whether any authority looks at an idea like this to consider whether it is safe to grow vegetables in. |

And in reasonable amounts if you choose the right species and mostly stripped bark. It is pretty impressive to find heaps of bark steaming in the woods in mid-winter and on a still day the smell of it lingers in the air. Regards, Martin Brown |

They worked OK but having made holes near the base of the bags (as instructed) I found that water tended to drain straight through. Consequently they needed watering more often than peat bags. . -- Neil Visit my Peak District walking website - www.peakwalking.co.uk |

I forgot to make the holes! I did wonder whether they'd retain water - but when I checked them the other day they seemed fine after their initial soaking a week ago.

I guess it builds up in the sealed bag and smells pretty strong when it is first opened. It seems to have calmed down a bit after several days. Still, just because this chemical is produced naturally doesn't necessarily mean that it is harmless to grow vegetables in it. Hopefully the concentartion is too low to be a concern. |

writes I am not sure whether organic actually means anything when applied to growbags (I know what it ought to mean, but does it?). The use of the expression 'organic' as applied to horticulture is complex and much misunderstood. It came into use about 50-60 years ago when horticulture and agriculture were rapidly changing from what had been 'traditional' methods to more modern methods which rely heavily on the use of chemicals. 'Organic' was and still is meant to indicate the use of living organisms as distinct from using inert chemicals. It applies to grow bags as much as any other product. What I am not sure about is whether any authority looks at an idea like this to consider whether it is safe to grow vegetables in. Yes, very much so. Organic standards are developed in the EU as part of their Food and Agriculture policies. Participating countries such as UK are responsible to see that those standards are adhered to. No produce can be sold in UK as organic unless it has an accredited certification. Commercial growers and producers are bound by law to keep to organic regulations. That is monitored in UK mainly by the Soil Association at Bristol, who are authorised to issue and monitor certifications. Recreational gardeners are not legally bound by organic regulations, but for those who wish to maintain the recognised standards of organic gardening, HDRA give guidance and advice, based on EU regulations where they are applicable. Further details about organic gardening can be seen in the urg FAQ at: http://www.nugget.demon.co.uk/MetaFA...gardening.html -- Alan & Joan Gould - North Lincs. |

In this particular case I think the worst that will happen is that the roots will be less willing to enter the compost. Regards, Martin Brown |
