CLAY SOIL PROBLEMS
Hi, I am new to gardening and a lot of my border plants this year have died in spite of putting a bit of compost and top soil around the roots when planting, plus watering and regular dead-heading. I have clay soil which can be a bit like glue when digging a deep hole! Do you suggest a soil testing kit, if so which is a good one and also how do you know which plants will thrive and which wont when viewing them all outside retail shops please? Thank you.
