As I am starting from a blank canvas it could be said that it is in this decade.
Yes I am growing more fruit and veg than ever beore - never grown fruit at all, and only really tinkered with veg, that is very 'now'.
Plants, yes, I am encouraging wild life and bees, but I think I have done that before. I have a couple of water features, one is a fountain/bird bath, one is an old galvanised bath - this century I guess.
Someone came last year when a lot of it was half way through the hard landscaping and described it as qwerky, Felt pleased with that, - now what decade would that be - that is just me, now
