About Pink Lady flowering quince

Chaenomeles x superba 'Pink Lady' · also called Pink Lady flowering quince, flowering quince · flowering

One of the most popular flowering quinces, 'Pink Lady' produces a generous flush of deep rose-pink flowers on bare stems from late winter to mid-spring. A compact, thorny deciduous shrub ideal for mixed borders, informal hedging, or wall training. Small apple-like fruits ripen to yellow-green in autumn and can be used for jellies.

Growth habit: Deciduous, compact, suckering shrub with thorny branches

What fertiliser pink lady flowering quince actually wants — and why

Pink Lady flowering quince 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 pink lady flowering quince: 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 pink lady flowering quince, 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 pink lady flowering quince:

Apply a balanced slow-release fertiliser in early spring as growth begins. A supplementary high-potash feed in early summer supports flower bud initiation for the following season. 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 pink lady flowering quince is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.
