About Therese Bugnet Rose
Rosa 'Therese Bugnet' · also called Therese Bugnet, Thérèse Bugnet · flowering
Thérèse Bugnet is an extremely hardy rugosa-hybrid shrub rose with double, lilac-pink, richly fragrant blooms that repeat from early summer to autumn. Bred on the Canadian prairies, it withstands brutal cold, has near-thornless plum-coloured stems that glow in winter, and offers disease-resistant foliage with good autumn colour.
Growth habit: Upright, vigorous, suckering shrub with almost thornless reddish-plum canes that are striking in winter. Double flowers begin early and repeat through to autumn; it sets few hips because of the double blooms.
What fertiliser therese bugnet rose actually wants — and why
Therese Bugnet 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 therese bugnet 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 therese bugnet 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 therese bugnet rose:
Feed lightly in spring with a balanced rose fertiliser or compost mulch. It is more tolerant of feeding than strict rugosas, but moderation still gives the best balance of bloom and healthy, manageable growth. 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 therese bugnet 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 therese bugnet rose
Follow the flowering-feed label rate for therese bugnet 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 therese bugnet rose first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the therese bugnet rose watering schedule.
Signs you are over-feeding therese bugnet rose
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for therese bugnet 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 therese bugnet 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 therese bugnet rose care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Container-grown therese bugnet 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 therese bugnet 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 therese bugnet 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 therese bugnet 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.
Should I flush the soil of therese bugnet rose?
Container-grown therese bugnet 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.
