About White Versailles Currant
Ribes rubrum 'White Versailles' · also called White Versailles currant, white currant · edible
'White Versailles' is a classic white currant (a sweeter, pale form of redcurrant) bearing translucent, pale-yellow berries on long trusses in mid-summer. Sweeter and less acidic than redcurrants, it is excellent eaten fresh. Vigorous and reliable, it fruits on a permanent framework and trains as a bush, cordon, or fan in sun or part shade.
Growth habit: Vigorous, upright deciduous shrub fruiting on spurs on a permanent framework of older wood. Pruned by spurring back side-shoots, it trains readily as an open-centre bush, single or multiple cordon, or wall-trained fan, just like its redcurrant kin.
Watch for — Birds taking pale fruit: Ripe white currants are easily stripped and can be hard to spot when ready. Net the bush or grow in a fruit cage as the trusses turn translucent.
What fertiliser white versailles currant actually wants — and why
White Versailles Currant feeds in two distinct phases — balanced to build the plant, then high-potassium the moment flowering starts to set and fill a heavy crop.
Balanced (even N-P-K) at planting for roots and frame, then switch to a high-potassium ("high-potash") tomato-style feed once the first flowers open — potassium is what sizes and ripens fruit, not nitrogen.
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 white versailles currant: 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 white versailles currant, 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 white versailles currant:
As for redcurrants, feed for potassium: apply sulphate of potash or a high-potassium fertiliser in late winter and a light balanced spring feed. Avoid excess nitrogen, which softens growth and invites mildew. Mulch annually with compost; feed container plants regularly through summer. So: a balanced feed or compost at planting, then a high-potash liquid every 1-2 weeks from first flower through harvest across the main season (spring through early autumn).
The dormant-season rule matters more than the exact interval: skip feeding entirely when white versailles currant 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 white versailles currant
Follow the crop-feed label rate for white versailles currant — these are calibrated for hungry vegetables. Consistency through fruiting matters more than strength; erratic feeding causes problems like blossom-end rot.
Feeding always goes onto already-damp soil, never dry roots — water white versailles currant first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the white versailles currant watering schedule.
Signs you are over-feeding white versailles currant
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for white versailles currant:
- Vigorous dark-green leafy growth but few flowers or fruit (excess nitrogen).
- Lush foliage hiding the crop; soft growth prone to pests and disease.
- Salt crust on the soil and scorched leaf edges in containers.
Signs you are under-feeding white versailles currant
- Pale, yellowing lower leaves and stunted growth.
- Small fruit, poor set, and a quickly exhausted plant.
- Blossom-end rot and weak cropping from erratic or insufficient feeding.
If the symptoms point at watering, light or roots rather than nutrition, the full white versailles currant care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
In containers, fertiliser salts build up fast — water white versailles currant thoroughly so excess drains from the base each time, and flush pots with plain water every few weeks to prevent a damaging salt build-up.
Organic vs synthetic feeds for white versailles currant
Organic options
Garden compost or well-rotted manure dug in before planting, plus a liquid comfrey or seaweed feed once fruiting starts. UK: comfrey feed or organic Tomorite; US: Espoma Tomato-tone or Neptune's Harvest. Builds soil and feeds in one.
Synthetic / liquid feeds
A balanced feed at planting then a high-potash tomato feed in fruiting — UK: Growmore at planting then Tomorite (Levington) or Phostrogen; US: a balanced 10-10-10 then Miracle-Gro Tomato or a bloom booster.
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 white versailles currant look like?
Vigorous dark-green leafy growth but few flowers or fruit (excess nitrogen). Lush foliage hiding the crop; soft growth prone to pests and disease. Salt crust on the soil and scorched leaf edges in containers. Staying on a high-nitrogen feed once white versailles currant starts flowering is the classic error — you get a huge leafy plant and a disappointing crop. Switch to high-potash the moment flowers appear.
Should I flush the soil of white versailles currant?
In containers, fertiliser salts build up fast — water white versailles currant thoroughly so excess drains from the base each time, and flush pots with plain water every few weeks to prevent a damaging salt build-up.
