To avoid all this stress, simply subscribe to the RHS email newsletter in September. They’ll send you a “friendly reminder” that feels like a nudge from a gardening auntie. It’s the easiest way to avoid the scramble.
And if you still miss the sale? There’s always the local garden center on a rainy Saturday. It’s not Chelsea, but the coffee is cheaper and no one judges your sunhat. Life goes on, and so do the begonias.
