I wondered what those blemishes were, thought it might be heat scorch but I try not to water when the sun is on them. Will slug bait in there today, they will be busy laying eggs soon.. The 'Blue Pearl" is 2 years old but think the location is too hot. The soil they are in is sandy but there is a tree in that bed with roots. Was fine when I first put this in but the tree is getting bigger.
I have not been out of the house since getting home so no have not looked.
