More weird earthquake stuff

Well for the most part we are all ignoring the earthquake and it's aftershocks. No one has anything fixed but there is now plenty of food at the supermarket so... priorities, priorities. Except that there has been an annoying casualty at my house. Behind the garage (where we had our veggie garden until the neighbours grew their NZ native tree too big so it casts a huge shadow and drops leaves that smother everything.... and then the chickens....) there is a crack in the ground from the earthquake. Several cracks actually... but no liquifaction. Anyway my lemon tree is now dying. The leaves are going yellow and falling off, and the apple tree doesn't look great either. The grass back there has also died off in huge chunks. What the????? I'm about to go to the shops and try to find something to perk up my lemon tree.... like catnip for lemons. Fingers crossed it exists. I refuse to lose anything else to this earthquake.
PS I forced the front door open today because of the lovely weather and breeze. You have no idea how much you miss having a front door until it is gone.
