About Fourth of July Rose
Rosa 'Fourth of July' · also called Fourth of July, WEKroalt · flowering
Fourth of July is a vigorous climbing rose from Weeks Roses and the first climber to win All-America Rose Selections (1999). It bears bold semi-double blooms splashed and striped red and white in large clusters, with a light apple-and-rose scent. Fast-growing and free-flowering, it covers fences, arbours, and pillars across a long season.
Growth habit: Vigorous, fast-growing climbing rose with long flexible canes that flower repeatedly in large clusters; trains readily on fences, arbours, and pillars.
What fertiliser fourth of july rose actually wants — and why
Fourth of July 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 fourth of july 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 fourth of july 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 fourth of july rose:
Feed a vigorous climber generously: balanced rose fertiliser in early spring and again after the first flush, with a spring mulch of well-rotted manure. Stop feeding by late summer so the long canes ripen 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 fourth of july 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 fourth of july rose
Follow the flowering-feed label rate for fourth of july 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 fourth of july rose first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the fourth of july rose watering schedule.
Signs you are over-feeding fourth of july rose
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for fourth of july 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 fourth of july 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 fourth of july 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 fourth of july 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.
