What fertiliser pelargonium 'tip top duet' actually wants — and why

Pelargonium 'Tip Top Duet' 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 'tip top duet': 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 'tip top duet', 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 'tip top duet':

Feed fortnightly in spring and summer with a balanced liquid feed, moving to a high-potash feed as buds form to prolong flowering. Stop feeding in autumn and winter while growth is slow. 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 pelargonium 'tip top duet' 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 'tip top duet'
