About Queen of Sweden Rose
Rosa 'Queen of Sweden' · also called Queen of Sweden, Austiger · flowering
Rosa 'Queen of Sweden' is an upright, exceptionally healthy David Austin English shrub rose with cupped, then shallow-cupped soft apricot-pink rosettes of perfect symmetry. It has a light myrrh fragrance, an unusually erect and tidy habit, and repeat-flowers freely, making it excellent for formal borders, hedging and cutting.
Growth habit: Distinctly upright, narrow, well-branched shrub that holds its flowers neatly aloft; repeat-flowers freely and suits formal planting or low hedging.
Watch for — Bloom fading in heat: The soft apricot-pink can pale quickly in strong sun and high heat; this is normal, and removing spent blooms keeps fresh colour coming.
What fertiliser queen of sweden rose actually wants — and why
Queen of Sweden Rose is a heavy-blooming flower with a big appetite — a regular high-potash feed through the season is what drives a long, dense display.
A high-potassium ("high-potash") flowering feed — tomato-style or a dedicated bloom/rose feed. Potassium powers flowering; a high-nitrogen feed gives you a leafy plant with disappointing bloom.
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 queen of sweden rose: 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 queen of sweden rose, 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 queen of sweden rose:
Apply a balanced rose fertiliser in early spring and again after the first flush in summer, with an annual mulch of well-rotted manure or compost. Stop feeding by late summer so growth hardens before frost. For a hungry bloomer that means feeding regularly — sparingly through the growing season — right through flowering across the main season (spring through early autumn), tapering as blooming ends.
The dormant-season rule matters more than the exact interval: skip feeding entirely when queen of sweden rose 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 queen of sweden rose
Follow the flowering-feed label rate for queen of sweden rose, or half strength if feeding very frequently. These plants genuinely use the nutrients — under-feeding shows up fast as a thin display.
