Thanks… Sadly the only things we’ll get time to plant this year are retaining wall footings 😦
Grow stuff in pots!! then you can keep on with your digging in the rocky ground…
this winter all my veg planting will be in pots and tubs and I find that they do well provided I keep up with the water and some organic feeding. Its amazing how much can be planted in one of the old black recycling tubs.
Winter is also a really good time to move deciduous fruit trees. I have a greengage that is too close to the back verandah and I plan to shift it in late June.
