Little or nothing. Rich, especially nitrogen-rich, soil pushes foliage at the expense of flowers in this plant — lean ground is the technique, not a deficiency.
For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for accent scarlet busy lizzie: match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.
How often to feed accent scarlet busy lizzie, and which months
Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For accent scarlet busy lizzie:
Feed weekly with a high-potassium liquid fertiliser from 4-6 weeks after planting. Regular feeding is essential for continuous bloom; nitrogen-heavy feeds push lush foliage at the expense of flowers. In practice: no routine feeding at all for accent scarlet busy lizzie — at most a thin compost mulch for soil structure, never a flowering or nitrogen feed.
