My worries are seasonal. Right now I worry when I see the daily afternoon wilting of things: Elephant Ear, Angel's Trumpets, Trailing Daisy etc, around 3-7 pm. They all like some fair amount of sun. But our summer heat affects even them. They all perk up again once the heat dissipates. But I have to fight the urge to water.
I get anxious whenever I have to turn or move my Plumeria trees. They are so brittle that branches easily snap off.
