What I have done that is really important is-
Installed a water tank (we got some awesome rain)
Started growing dynamic accumulators that will encourage diversity and nutrient take-up in plants.
Mulched the crap out of everything.
Erected trellises for shade and extra growing space in the veggie garden.
Experimenting with new and unusual heirloom vegetables...especially tomatoes!
I now have around 25 varieties of tomato, and only 15 in the ground...I need more ground!
I have some new water-saving devices, and this weekend I am making compost tea...delicious :o)
Sorry about all of the exclamation marks, I love my life!
