Thanks for your advice previously about which manure(Westland's Grow sure farmyard manure) is the best. I did find the product in my local B&M store. My question is, one part of the garden is under a Pine tree, and the soil is covered in pine needles. Do I need to remove the needles before I put the manure on. Bearing in mind I am just putting the manure on top of the soil in other parts of the garden. Or do I need do dig the needles into the soil. Once again I thank you for any advice.
