Having an extra lid is most helpful when propagating seeds.
This allows you to prepare your seeds in the lid away from the garden – perhaps in your shed.
Then swap over the lid on top of the Compot for the lid full of seeds.
It is not absolutely necessary for you to do this. Just an extra option.
ALSO
It has been known for people to forget they have a compot in the ground and run over their soil with a rotary hoe.
This will no doubt ruin your lid so you may need just a replacement lid.
I only have the green ones listed to replace as the black lids are mostly used above ground.
However if you need replacement Black Lids you can order the green lids and just put a note in the extra instructions box to swap for black lids.
Failing that just call me (0467 006 529 of 07 3357 3716) and order over the phone.
