All looking very good, making good progress. Don't forget burying mulch into the soil will take away a lot of the nitrogen from the soil, so it will need some compensation. And killing the unkillable... I got some blackberries from down south, everyone warned me, noxious weed, will grow out of control and take over. 3 plants started as cuttings 100mm tall, got to about 800mm tall each. Then one day leaves all yellow, next day all leaves dropped, 2 weeks later all branches dead. 1 has just re-sprouted ( 3 leaves ) from roots, the other 2 are 💯% dead. So much for unkillable.
