About Impatiens walleriana 'Xtreme Salmon'
Impatiens walleriana 'Xtreme Salmon' · also called Xtreme Salmon Impatiens, Busy Lizzie Salmon · flowering
A shade-loving busy lizzie with abundant flat salmon-pink flowers on a compact, mounded plant. Classic bedding and basket impatiens, it flowers non-stop in shade to part shade through summer. It needs consistently moist, humus-rich soil and shelter from hot afternoon sun, and remains self-cleaning, dropping spent blooms without deadheading right up to first frost.
Growth habit: Compact, well-branched mounding habit that fills out into a dense flower-covered cushion; self-cleaning, needing no deadheading.
Watch for — Leggy growth with few flowers: Too much shade or excess nitrogen causes stretched, sparse plants. Provide bright dappled light and pinch tips early to encourage bushy, floriferous growth.
What fertiliser impatiens walleriana 'xtreme salmon' actually wants — and why
Impatiens walleriana 'Xtreme Salmon' flowers best on poor soil — feed it and you get a lush leafy plant with very few blooms, the exact opposite of what you want.
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 impatiens walleriana 'xtreme salmon': 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 impatiens walleriana 'xtreme salmon', 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 impatiens walleriana 'xtreme salmon':
Feed every 2-4 weeks with a balanced liquid fertiliser, or use a controlled-release feed at planting. Avoid over-feeding with high nitrogen, which produces lush foliage at the expense of flowers; container plants need feeding more often than bedded ones. In practice: no routine feeding at all for impatiens walleriana 'xtreme salmon' — at most a thin compost mulch for soil structure, never a flowering or nitrogen feed.
The dormant-season rule matters more than the exact interval: skip feeding entirely when impatiens walleriana 'xtreme salmon' is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.
What strength to mix for impatiens walleriana 'xtreme salmon'
None is the correct answer for impatiens walleriana 'xtreme salmon'. The flower-versus-foliage trade-off is the whole point: hold back and you get the display.
Feeding always goes onto already-damp soil, never dry roots — water impatiens walleriana 'xtreme salmon' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the impatiens walleriana 'xtreme salmon' watering schedule.

Organic vs synthetic feeds for impatiens walleriana 'xtreme salmon'
Organic options
A thin compost mulch for soil structure is the absolute most; mostly, give it nothing. UK/US: leave it lean — no manure, no liquid feed. Poor soil is the active ingredient here.
Synthetic / liquid feeds
