as a novice gardener, do I deadhead Rudbeckia (aka black-eyed susan)?
Cardiff, United Kingdom
given as seedling. Potted up straight away. Doing really well in large pot (staked) has produced lots of flowers (some have petals eaten - earwigs perhaps?). Wondering if dead-heading prolongs production. (I live in s.wales and garden faces south)
