  • weekly maintenance checklist

    • moisture check:
      • feel top 3–5 cm soil.
        • if dry → deep-water ~10–15 l per clump;
        • no standing water >1 hour.
    • mulch:
      • keep 5–8 cm organic mulch;
      • fluff/top up;
      • pull back 3–5 cm from the crown.
    • feeding (if it’s a feeding week):
      • compost tea or vermicompost extract 2–4 l/plant;
      • rinse in with water.
    • canopy & sanitation:
      • remove yellow/old/diseased fronds;
      • keep ≥3–5 strong fronds per clump;
      • tie floppy fronds to open the crown.
    • harvest for stimulus:
      • cut tender shoots at 15–20 cm before unrolling;
      • take ≤⅓ of new shoots per clump;
      • rotate clumps.
    • pests:
      • check leaf undersides.
      • if aphids/scale/mites → morning rinse + 1–2% soap or neem 5 ml/l;
      • repeat in 3–5 days if needed.
      • hand-pick slugs/snails or set traps.
    • fungal watch:
      • if spots/powder → spray baking soda 1 tsp/l + a drop of soap;
      • improve airflow;
      • avoid evening overhead watering.
    • structure & spacing:
      • clear debris in a 20–30 cm ring;
      • thin encroaching shoots to keep 45–60 cm between clumps.
    • drainage pass:
      • after heavy rain, open channels so crowns never sit in puddles.
    • log it:
      • note date, rainfall, liters watered, feed (y/n), pests seen, and record amount of shoots harvested.
  • site & soil
    • bright shade (50–70% shade), high humidity, wind-sheltered
    • deep, rich, constantly moist soil; lots of compost; ph ~5.5–6.5
    • mulch 5–8 cm (leaves/coco husk/ straw) to keep roots cool and moist
  • watering (maximize flushes)
    • keep evenly moist, never waterlogged
    • dry season: deep water 2–3×/week; rainy season: improve drainage, loosen mulch if soggy
  • feeding (organic)
    • every 2 weeks: compost tea or diluted vermicompost extract (2–4 l/plant)
    • monthly: side-dress 1–2 kg mature compost/plant
    • every 6–8 weeks: potassium boost for thicker shoots—seaweed extract or a small handful of wood ash/m² (rinse in next watering)
  • canopy management
    • always leave 3–5 strong fronds per clump for photosynthesis
    • remove old/yellow or congested fronds weekly for airflow (less disease, more new shoots)
  • harvest rules (don’t stunt the plant)
    • cut tender shoots at 15–20 cm length, before unrolling
    • never take more than ⅓ of emergent shoots from a clump at once; rotate clumps
    • check every 2–3 days in warm, wet weather—frequent light harvests trigger more flushes
  • spacing & renewal
    • maintain 45–60 cm between clumps; thin crowded plants
    • divide vigorous clumps every 8–12 months (rainy season): replant healthiest crowns at original depth with fresh compost
  • pests & diseases (organic)
    • slugs/snails: handpick, beer traps, copper barriers
    • sap pests (aphids/scale): morning water rinse + 1–2% soap spray; encourage ants away from crowns
    • crown/leaf spots: improve airflow, avoid evening overhead watering; weekly baking soda 1 tsp/l + a drop of soap if needed
  • weekly checklist
    • inspect fronds (pests/spots), remove old leaves
    • top up mulch, ensure soil stays evenly moist
    • harvest young shoots; rotate clumps
    • tie up floppy fronds to keep crown open
  • monthly checklist
    • side-dress compost; potassium boost if shoots thin
    • divide or thin any overcrowded clumps
  • temperate note (ostrich fern, matteuccia struthiopteris)
    • similar care but cooler, moist woodland shade; ph ~6–7
    • harvest only 2–5 fiddleheads per crown per spring, then stop and let fronds grow out
    • divide every 3–5 years in early spring
  • important safety note
    • avoid bracken fern (pteridium aquilinum)—it’s not recommended for eating.
