About Mojito Mint
Mentha × villosa · also called Mojito Mint, Cuban Mint · herb
Mojito Mint is the authentic Cuban cocktail mint, prized for its broad, soft leaves with a sweet, mild spearmint flavour and subtle citrus undertone. A hybrid of exceptional vigour, it thrives in moist soil with full sun to partial shade. Contain it in pots to prevent its rhizomes from overtaking the garden.
Growth habit: Upright to spreading, vigorously rhizomatous herbaceous perennial. Broad, soft, lightly hairy leaves on square stems to 60 cm; pale pink flower spikes in mid to late summer.
What fertiliser mojito mint actually wants — and why
Mojito Mint is a soft, fast leafy herb that you harvest hard — a modest balanced feed keeps tender growth coming without tipping it into bland or bolting.
A balanced general feed (even N-P-K) at modest strength — enough nitrogen to keep replacing the leaves you pick, but not so much that flavour thins or it bolts to seed.
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 mojito mint: 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 mojito mint, 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 mojito mint:
Apply a balanced liquid fertiliser monthly during spring and summer to support the high leaf-production rate. A feed with slightly elevated nitrogen (e.g. 10:5:5) encourages leafy growth for harvesting. Reduce to nil in autumn and winter. Top-dress pots with fresh compost each spring. In practice: a balanced liquid feed every few weeks through the main growing and harvesting season (spring through early autumn), more often the harder you are picking it.
The dormant-season rule matters more than the exact interval: skip feeding entirely when mojito mint 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 mojito mint
Half strength is a sensible default for mojito mint — enough to fuel regrowth after cutting, gentle enough that the leaves stay aromatic rather than watery.
Feeding always goes onto already-damp soil, never dry roots — water mojito mint first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the mojito mint watering schedule.
Signs you are over-feeding mojito mint
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for mojito mint:
- Fast, soft, pale growth with diluted, less aromatic flavour.
- Early bolting (running to flower) and a bitter edge.
- Salt crust and scorched tips on container plants.
Signs you are under-feeding mojito mint
- Pale, slow regrowth after cutting and small leaves.
- A tired, stalled plant that cannot keep up with harvesting.
- Yellowing older leaves in a long-spent pot.
If the symptoms point at watering, light or roots rather than nutrition, the full mojito mint care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Pot-grown mojito mint builds up feed salts quickly — water until it drains each time and flush the pot with plain water every few weeks, especially on a sunny windowsill.
Organic vs synthetic feeds for mojito mint
Organic options
A diluted seaweed feed or worm-casting tea keeps soft growth coming without overdoing it. UK: dilute seaweed or Westland; US: Espoma Garden-tone or Neptune's Harvest. Gentle, hard to overdo, flavour-friendly.
Synthetic / liquid feeds
A balanced liquid feed at half strength through harvesting — UK: Phostrogen, Baby Bio or Westland; US: Miracle-Gro all-purpose at half strength. Fast regrowth; just do not overdo the nitrogen.
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 mojito mint look like?
Fast, soft, pale growth with diluted, less aromatic flavour. Early bolting (running to flower) and a bitter edge. Salt crust and scorched tips on container plants. Over-feeding mojito mint with strong nitrogen is the usual mistake — it grows fast and lush but the leaves turn bland and it bolts to flower sooner, ending the useful harvest early.
Should I flush the soil of mojito mint?
Pot-grown mojito mint builds up feed salts quickly — water until it drains each time and flush the pot with plain water every few weeks, especially on a sunny windowsill.
