How big is the tree, Happiness? Small trees can be dug up and replanted in the winter.

Linda, my garden is the same, free draining, crumby soil in the summer, with most of the nutrients in the river!!. Lots of compost, muck, and anything that will hold the water and nutrients where the plants need them. I keep chickens, and they provide the muck and straw which activates the compost which feeds the soil the following year.

Cheers, Bron.
