This is the same photograph that I showed yesterday. It is a tiny sunflower plant that germinated in situ, with its seed coat still attached. That was yesterday.
This morning I went out again to see how it was doing, along with a number of other baby plants.
Here it is today... same plant, same spot.... and all that is left is the stalk and no growing point.It will die. This is the work of earwigs! One can continue to replace plants, hoping to eventually get ahead of the pests, but it is very frustrating.
