In short: A 60-day feeding plan for SW88 mint follows the growth stages: days 0–7 rooting, 8–20 recovery, 21–35 canopy development, 36–50 biomass build-up and 51–60 pre-harvest. The basis is organic base dressing, light nitrogen early, balanced potassium later and regular microbial drenches. Repeat the cycle after every cut.

Base dressing before planting

Well-rotted manure or compost at about 1.5–2 kg/m², mixed into the topsoil.
On acidic soil, apply lime or dolomite 1–2 weeks before planting.
Mix compost or a Trichoderma product into the base dressing to limit root diseases.

The 60-day schedule

Stage	Goal	Feeding and care
Days 0–7	Rooting	No extra feed; keep evenly moist, shade if very sunny
Days 8–20	Recovery, new leaves	Diluted fish liquid fertilizer or liquid organic feed weekly
Days 21–35	Canopy development	Organic top dressing (about 0.5 kg/m²); weed and loosen soil
Days 36–50	Biomass build-up	Add potassium (wood ash, banana peel liquid or organic potash); microbial drench
Days 51–60	Pre-harvest	Stop nitrogen 10–15 days before cutting; watch buds to pick the cutting day

After each cut

Clear old leaves, weed, top-dress with organic feed and apply microbes within 3–5 days so the crop sprouts quickly. Then repeat the 60-day cycle.

FAQ

Why stop nitrogen before cutting?

Late nitrogen produces soft, watery leaves with lower oil content and more disease.

Can mineral fertilizers be used?

Conventional fields can use them as recommended. Our model prioritises organic inputs – see the three-pillar model.
