This patch of rainforest is in pretty good nick and the community here is trying to keep it that way. But there are a few weeds. Fortunately, most of these are confined to the edges, where there's plenty of light. (Coffee is the exception. That can germinate and survive beneath the forest canopy.)
Brazilian nightshade (Solanum seaforthianum) has popped up in the garden. There's only a single plant but it's been cut back repeatedly by previous owners. What should be a delicate vine now has a thick stem and deep roots. It's time to take action with a pruning saw and weed killer. If only I could fit lasers to the catbirds.
