Hi Bunks,
I'm also in Australia, practising mad summer watering skills (this is my first year gardening & I'm a bit scared of the looming summer to be honest!). I don't live in an apartment but have tomatoes and things growing on my porch, where the water tends to gather & go bad in the centre of the concrete- I imagine it isn't doing the concrete any favours. I soak it up with old towels. Not a great solution. Be very happy to hear of anything better.

How deep are the trays under your pots? Have you had any mosquito issues? I know I need to add some sort of water reservoir system to my pots but I'm paranoid of mosquitos.

Hi slashy
yeah ditto bout summer coming up, its my first year too...
The trays are quite shallow, only a centimetre high. I haven't had any problems with mozzies, the water evaporates quickly, I'm also in a windy area. I'm working on a kind of sponge system that will hopefully draw the water away and into a bucket, though i don't know how successful that will be. Will keep you posted. If any ones got a better idea, let us know!

What a great idea! Let us know if it works out. I have a terrible problem with standing water in one spot on my balcony and I worry about the long term damage it might cause.
