About Jubilee Celebration Rose

Rosa 'Jubilee Celebration' · also called Jubilee Celebration, Aushunter · flowering

Jubilee Celebration (Aushunter) is a David Austin English shrub rose named for the Queen's Golden Jubilee. Large, domed, salmon-pink blooms with gold-tinted petal undersides open from rounded buds and carry a fruity fragrance of lemon zest and raspberry. Vigorous and rounded to about 1.2m, it repeat-flowers freely and makes an excellent flowering hedge, bed or border plant.

Growth habit: Vigorous, rounded, bushy English shrub rose with sturdy stems; repeat-flowers well and works as a flowering hedge.

Watch for — Heavy blooms nodding: Large domed flowers can weigh stems down. Feed for strong growth and site in a sheltered spot; this nodding habit is partly natural to the variety.

What fertiliser jubilee celebration rose actually wants — and why

Jubilee Celebration 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 jubilee celebration 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 jubilee celebration 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 jubilee celebration rose:

Feed with a balanced rose fertiliser in early spring and again after the first flush. Mulch with rotted manure or compost in spring. Stop feeding by late summer so soft growth hardens off 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 jubilee celebration 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 jubilee celebration rose

Follow the flowering-feed label rate for jubilee celebration rose, or half strength if feeding very frequently. These plants genuinely use the nutrients — under-feeding shows up fast as a thin display.

Feeding always goes onto already-damp soil, never dry roots — water jubilee celebration rose first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the jubilee celebration rose watering schedule.

Signs you are over-feeding jubilee celebration rose

Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for jubilee celebration rose:

Lots of lush leaves but few flowers (too much nitrogen).
Scorched leaf edges and salt crust from too-strong or too-frequent feeds.
Soft, sappy growth prone to aphids and mildew.

Signs you are under-feeding jubilee celebration rose

Sparse, small, short-lived flowers and pale foliage.
A tired plant that stops blooming early in the season.
Weak growth and poor repeat-flowering after the first flush.

If the symptoms point at watering, light or roots rather than nutrition, the full jubilee celebration rose care brief covers soil, humidity and the common problems for this species.

Flushing and leaching the salts

Container-grown jubilee celebration rose accumulates feed salts fast with frequent feeding — water until it drains each time and flush pots with plain water every few weeks to prevent scorch.

Organic vs synthetic feeds for jubilee celebration rose

Organic options

A liquid comfrey or seaweed feed (naturally potassium-rich) plus compost or well-rotted manure as a mulch. UK: comfrey feed, organic Tomorite, or rose feed; US: Espoma Rose-tone or Neptune's Harvest. Feeds and improves soil.

Synthetic / liquid feeds

A high-potash flowering feed on a regular cadence — UK: Tomorite (Levington), Phostrogen or a specialist rose feed; US: Miracle-Gro Bloom Booster or a rose food. Fast, reliable bloom response.

Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.

Lots of lush leaves but few flowers (too much nitrogen). Scorched leaf edges and salt crust from too-strong or too-frequent feeds. Soft, sappy growth prone to aphids and mildew.
