PLANNING TO START A HERB GARDEN

Now that the overgrown cacti in front of my mum's house has been chopped down and gotten rid off, I have made plans to start a mini herb garden at that spot.  Why?  This is to prevent people from using the place to dump their rubbish.  My mum had planted the cacti there as the place was used as a rubbish dump.  The stench from the unsightly rubbish was making it unbearable for my mum and her immediate neighbour.
After the cacti were cleared, I started to fear that the place would again become what it used to be and so took action to prevent it.  As you can see, I have placed pots there to indicate that the place will be used.
