A bike ran over the Science World site this afternoon.
I get the impression it was not deliberate but still, everytime it happens it is a setback to the growth of the plants.
Took pictures before and after.
A string fence maybe 30cm [12in] high marked with bright flagging might solve the problem or make it a higher target.
On the boulevard, I added another bag of coffee grounds last night and this morning watered it. After 20 minutes, the grass underneath was still dry, so turned it over and watered for another 15.
