The [RHS snapdragon profile](https://www.rhs.org.uk/plants/69565/antirrhinum-majus/details) provides general species guidance; commercial crop timing depends on light and day length. ## Maintenance Harvest stems as lower florets open and keep them upright after cutting. For garden-grown plants, remove spent spikes; RHS notes that deadheading can prolong flowering.
