How to prune tulipa 'menton'

Deadhead immediately after flowering (mid to late spring); leave foliage until fully yellow (early summer). Snap or cut the spent flower head off cleanly at the top of the stem. Leave the full stem and all leaves standing until they collapse and yellow on their own.

Once per season. Tulips need minimal pruning. Deadhead flowers promptly after they fade to prevent energy going to seed production, but leave all foliage intact until it yellows and dies back naturally — typically 6 weeks after flowering. The leaves are essential for replenishing the bulb for next year. Never tie or cut green foliage early.
