Hello All, I'm in my first season of using a greenhouse and to get me started I ordered a lot of bulbs which I happily potted up in B&Q multipurpose compost. I had long black trays with matting in them and put some grit on top then stood my pots on the grit. I thought the idea was that the plant roots would reach down to get the moisture therefore, grow good strong roots. I can only get to garden at the weekends so I thought this would be a good idea to ensure there is water through the week, that said, I don't drench them at the weekend, they only looked like they needed one water over the weekend but I did put 'a little' water in the tray - just enough to reach all pots but not that you would see it under the grit. Problem is - on checking the soil lately (things should be growing by now), a lot of the pots are surprisingly wet to the touch. I tipped one out today to find a rotten dahlia bulb and am worried about the rest but don't want to tip them out unless I have to. What have I done wrong? Do I tip the rest or see what happens?
