About Lady of Shalott Rose
Rosa 'Lady of Shalott' · also called Lady of Shalott, Ausnyson · flowering
Lady of Shalott is a robust, healthy David Austin English shrub rose carrying chalice-shaped, salmon-orange blooms with apricot reverses and a warm tea-and-clove scent. One of the most reliable and disease-resistant Austin roses, it repeat-flowers freely all season. Give it full sun and fertile soil; its bushy, arching habit also makes a fine short climber on a pillar.
Growth habit: Vigorous, bushy, well-branched English shrub rose with arching growth; repeat-flowering from early summer to autumn. Can be grown as a rounded shrub or trained as a short climber to around 2.5 m.
What fertiliser lady of shalott rose actually wants — and why
Lady of Shalott 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 lady of shalott 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 lady of shalott 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 lady of shalott rose:
Feed with a balanced rose fertiliser in early spring and again after the first flush in midsummer to fuel continuous bloom. Mulch with well-rotted manure in spring. Stop feeding by late summer so new 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 lady of shalott 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 lady of shalott rose
