Growth habit: Upright, bushy evergreen perennial with stiff, serrated, slightly sticky leaves and large ruffled flower heads.

What fertiliser pelargonium x domesticum 'hazel carey' actually wants — and why

Pelargonium x domesticum 'Hazel Carey' 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 pelargonium x domesticum 'hazel carey': 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 pelargonium x domesticum 'hazel carey', 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 pelargonium x domesticum 'hazel carey':

Apply a balanced liquid feed every 1-2 weeks in spring, moving to high-potash as buds form; stop feeding once flowering finishes and through winter. For a hungry bloomer that means feeding regularly — every 1-2 weeks — 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 pelargonium x domesticum 'hazel carey' 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 pelargonium x domesticum 'hazel carey'

Follow the flowering-feed label rate for pelargonium x domesticum 'hazel carey', or half strength if feeding very frequently. These plants genuinely use the nutrients — under-feeding shows up fast as a thin display.
