What a good idea, and they're not expensive either. 

Why do you want to keep the worms out? Are they not good for plants?

Yes, i was looking at these wheely things but most of my pots are too big and heavy for them.  🙂

I have never had much luck with natives in pots.  This particular pot was for some geraniums; I guess they also do not like to be too wet, so maybe they can be without a saucer,  but I hate it when water runs out from the bottom of pots and stains the paving.  Funny, I always thought that geraniums are so quintessentially "European village"  but apparently they are from Africa, and in Europe they have to store them for winter and lose about 1/2. 

 Geraniums like it dry. I have one long narrow bed on the hot side of the house. I have tried lots of things over the 40 years we have lived here and they are the only things that thrive, except for salvia. The geraniums I cut back at the end of winter, and if I particularly like one I break off bits and stick them in the ground. They strike readily. If the odd bit grows out too far over the path, I just snap it off as I go past. 

In pots they do ok, but wouldn't be happy with wet feet.

yes, geraniums do well in quite dry conditions, but in pots they do need bit more moisture.

You have to wonder if someone like that WOULD refund you, you may find yourself being yelled at again.

Yes, tay I would be concerned about that too. I think simone's advice was good - to call the store let them know the saucer is not in fact the right size and see what the meanie lady says about that... what her 'attitude' is.

If phone call goes badly, I  would also drop in the convo that I had planned to spend a few $1000 on my renovated garden but because of bad customer service I have rethought that, and will be spending that money elsewhere.

All very good points, Narelle.

And the "moisture indicator" violet is a good idea.
