Just getting into this gardening lark and I'm loving it. I was watching a shopping channel and found myself ordering 3 apple trees. They just arrived today. They are dwarf trees in a small bag of soil. What do I do now? I've brought large planters for them because I don't want them in the ground as the soil is a bugger (new build tiny garden, shallow soft soil) to dig and we won't be here for more than 2 years. I welcome your wisdom and advice.....
