It does seem VERY happy with compost around it and a good drink of Seasol, mind you everything seems to like that.

True! :) I stole some actual seaweed from the beach during the Sydney heatwave in February, and it's still making seaweed brew for me. But I also have bottles of seasol which I really should use up...

Ooh, enjoy the gardens! Living in Sydney, it's a bit far for me to get to their gardens, but if I ever make it down there, I'm definitely going to check it OUT!
