I am keen to document all the plantings, some trees have been lost, so we plant a different species, others are thriving, so it has been very much trial & error. The mulching has been
vital, in this climate, to keep the roots cool in the summer and warm in the winter. And of course retain the moisture, a great revolation to me has been the value of using cardboard/newspaper/old carpet etc and watching the worms bring the soil up to scratch.
Some areas I planted were like concrete when we started, and now they are transformed! just through good mulching. One of my big ornamental grasses! in a pot.
