when the guavas are out of season!
I plant callistemon and grevillias ostensibly as a permaculture strategy to encourage insectivorous birds and insects, because insectivores often also eat nectar as a source of carbohydrates. A good population of insectivores hanging around keeps the population of plant eating insects like grasshoppers and fruit flies down at a tolerable level.
But like most “sensible” garden strategies, it has some lovely side benefits! A comment from Kimmy set me thinking about how much more I get out of the garden, besides food. I grizzle about the wildlife getting all my fruit, but they do a good payback!
