I have been growing on some veggies in a conservatory on a wooden table. Had them standing on mats on top of a towel. Thought I was carefully watering AND moving the towel around and checking. Obviously I have been utter slacker and having just checked, oh dear.....! Large portion of (beech coloured)wooden table is darker due to moisture and quite a lot has black bits. Mould remover no good. Scraping black bits does remove a bit, but also chunks of table. DH will be delighted. Any ideas????
