All was well this morning. Then we went out for a bit over 2 hours. And came back to a scene of destruction on the balcony.
Something (I suspect white cockatoos) had attacked my succulents. It (or they?) must have gone from one pot to another.
The flat-ish terracotta pot on the top rack had 3 healthy succulents in it. One landed on the rack below (behind the pots), one ended up on the ground.
*bit of an understatement, actually.
