My garden has lots of small clumps of soil surrouded with what look like ash. when crupled, the inside looks like brown compost. My plants, both inside and outside the greenhouse look like they are covered with ash, the leaves gradually turn yellow , flowers and the vegetables are affected. Is there a link? I would be grateful for ideas on what it could be and how to get rid of it. Many thanks
