About Veterans' Honor Rose
Rosa 'Veterans' Honor' · also called Veterans' Honor, JACcofl · flowering
Veterans' Honor is a deep velvety-red hybrid tea introduced by Jackson & Perkins in 1999, with large high-centred blooms on long, near-thornless stems and a light raspberry fragrance. Disease-resistant and a superb cut rose, it flowers in repeat flushes. Grow in full sun with fertile, well-drained soil for the best colour and stem length.
Growth habit: Upright, vigorous, well-branched bush with long, nearly thornless flowering stems and large, glossy dark-green leaves; an excellent cut and exhibition red.
What fertiliser veterans' honor rose actually wants — and why
Veterans' Honor 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 veterans' honor 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 veterans' honor 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 veterans' honor rose:
Feed with balanced rose fertiliser at spring bud-break and again after the first flush, then a potash-rich feed by midsummer. Stop feeding by late summer so growth hardens before winter. 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 veterans' honor 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 veterans' honor rose
Follow the flowering-feed label rate for veterans' honor 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 veterans' honor rose first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the veterans' honor rose watering schedule.
Signs you are over-feeding veterans' honor rose
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for veterans' honor 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 veterans' honor 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.

Flushing and leaching the salts
Container-grown veterans' honor 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 veterans' honor 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.

What does over-feeding veterans' honor rose look like?
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. Using a high-nitrogen general feed on veterans' honor rose is the headline mistake — you grow a big leafy plant with few flowers. The second is simply under-feeding a genuinely hungry bloomer and getting a sparse, short display.
