I'm glad i don't have to worry about termites here in Cornwall! My heart goes out to you. I'm very lucky. If I want anything to top dress or mulch with I pop round to me nexr door neighbour and I can have as much as I loike. When I first moved in and the soil had been under black plastic and starved for 4 years, he brought me a whole trailer load and deposited it exactly where it was needed. I'm so lucky to have an endless supply of very well rotted cow manure next door.
By the way, I have daffodils out, helebores, crocus, iris, snowdrops and primroses. We had about 2 inches of snow this week and it was wonderful to see them peeping though it.
