Eriocaulon (verzorging — alle soorten)
Eriocaulon spp. (Eriocaulaceae)
🌍 Asia · India · Australia · tropical soft-water biotopes
Rare CO₂ Required Diff.: ★★★
📏 Foreground/Midground
📈 Slow
Rosette plants growing from a central crown. Roots longer than leaves — deep ammonia-rich soil required. ALL species are sensitive to KH. Direct CO₂ at substrate. White/firm root system = healthy plant; grey/soft = insufficient CO₂. Most accessible species is E. Vietnam (tolerates even KH 8). Most demanding are E. quinquangulare, E. ratnagiricum, and E. Nantoense. Never shade.
⚗️ Water parameters
🔵 KH
0–3 °dKH
⚠ KH <3° for most species
🌿 CO₂
20–40 ppm
Direct CO₂ AT SUBSTRATE
🪨 Ammonia-rich soil required — roots longer than leaves
🇳🇱 Dutch Style
Spectacular rosette plants for advanced Dutch style. Never shade — always clear view.
💡 Tips
- KH is the most critical parameter — above 3° plant declines
- CO₂ MUST be directed at substrate — not just the surface
- White firm roots = healthy; grey/soft = insufficient CO₂
- Never shade — always free spot
- Split rosettes for propagation (with razor blade or fingers)
- Vietnam = easiest species (KH up to 8)
- Quinquangulare = red species (KH <3°, CO₂ 50ppm ideal)
- Ratnagiricum = smallest species (~2.5cm)
- Nantoense = rarest and most expensive (€190)
🔍 Problems
⚠ Soft/grey roots
→ CO₂ too low at substrate level
⚠ Slow decline
→ KH too high (gradual effect)
⚠ No new leaves
→ Fe deficiency or insufficient nutrition
Eriocaulon Vietnam Variegated White
Eriocaulon sp. 'Vietnam Variegated White'
🌍 Vietnam
Rare CO₂ Required Diff.: ★★★
📏 Foreground/Midground
📈 Slow
Extremely rare white-variegated variant of E. Vietnam. Leaves show partially white or cream-yellow stripes and spots. Harder to keep than standard Vietnam — white zones are more sensitive. Extremely rare and sought-after by collectors.
⚗️ Water parameters
