That's something I've noticed too. All my Rowan trees are already laden with berries and ripened red. I cannot recall this happening in August before. Pyracantha & cotoneasters all laden with ripe berries already. Folklore says it's the sign of a harsh winter and making enough food to keep the wildlife alive. We'll see 🤔
Hope that piece of folklore is incorrect. Another theory is that plants produce more berries after a prolonged dry summer in order that if parent plant dies there is a seed bank for new plants to germinate and grow @angipangi
That theory would be fine down with you but up here it's barely stopped raining for the last 6 months. We'll just have to wait and see but I'm half hoping there's a good spell of frost because I think we need to kill off some of the garden pests and diseases that always seem worse after a mild winter.
