Used 'grow bags'
« on: May 31, 2020, 07:35:32 pm »
A client, with couple of glass-houses, has been storing used 'grow-bags' (for garden beds' mulching etc), but I can have some and I'm not about to pass-up an offer of some very good fibrous compost material for 0 !

Accepting that soil-borne diseases will always be a potential issue, I should be most grateful to hear of successes and disasters with recycled grow-bags whether they've been emptied for bulk use or recharged with nutrients in the bag. To note;  if I were to re-use in-bag, it would not be for another crop of tomatoes, chillies or similar. 

[On offer are used deep-fill bags with seaweed extract from, I seem to recall, Thomson & Morgan.]

I've used old growbags in raised beds, and just fed the plants  a little more than I would normally.  worked fine.  Never got any diseases, weren't used for tomatoes, peppers, cucumbers etc as previously
Always have been, always will be, a WYSIWYG - black is black, white is white - no grey in my life! But I'm mellowing in my old age

I've topped up raised beds without any issues that I could see. I cant really offer any real opinion other than I dont see a downside providing the hadn't previously had any harsh chemicals on them?

I would and do use this stuff for mulching on veg beds rather than as a pot soil medium again.
