Dig them out they are so small....
Wait till the weather gets cooler if it is too tiring in the heat..
Cheers..MM.

Are you living in a remote area? If not, you might be able to get someone to pull them out free for you:
(1) Offer them for sale on ebay, on the condition that the buyer has to dig them out and take them away. (You could start with a really low price, eg 99c, as your aim here is to entice someone to do the job for you rather than make a profit.)
(2) Offer them free (to anyone willing to dig them up and take them away) on Freecycle. You can find a list of all Freecycle groups on the link below and check if there's any in your area (there's one in Brisbane but guess you don't live there).

Here is a link that might be useful: All Freecycle groups

Hi Cestrum

Thank you so much for the freecycle link. I have posted a message offering a freezer. Jan

Yes, freecycle is very useful for things that are no longer needed but would be a shame to throw out.
