Osmocote Exact Tablet 8-9M — Slow-Release Fertiliser for Pots & Containers

Osmocote Exact Tablet 8‑9M delivers precise, reliable nutrition for potted plants, container-grown ornamentals and nursery stock — all in a simple tablet form. Designed to release nutrients gradually over 8 to 9 months (at around 21 °C), it gives plants a consistent supply of essential nutrients with minimal maintenance.

Features and Benefits

  • Easy application & uniform dosing: The cone-shaped tablets are pushed directly into the potting medium, ensuring every pot receives the same controlled dose.
  • High nutrient efficiency: Tablets dissolve gradually — no sudden nutrient spikes — reducing the risk of over-fertilization while supporting steady growth.
  • Locked in media — no wastage: Once inside the growing medium, tablets remain fixed and break apart over time, preventing fertiliser loss.
  • Long-lasting nutrition: Provides a season-long fertiliser supply (8-9 months under typical conditions), saving time and ensuring consistent plant care.

Nutrient Content (guaranteed analysis)

  • Total nitrogen (N): 14% (≈ 6.2% nitrate-N + 7.8% ammoniacal-N)
  • Phosphorus (P, water-soluble): 3.5%
  • Potassium (K, water-soluble): 9.1%
  • Magnesium (Mg): 1.2% (≈ 0.8% water-soluble)
  • Trace elements including Boron (B), Zinc (Zn) — in small but essential amounts.

This balanced formulation promotes healthy foliage development, root growth and overall plant vigour — especially useful for container-grown ornamentals where regular fertilising can be labour intensive.

How to Use

  1. Insert tablet into the potting medium — either directly under the dripper for drip irrigation, or around the root ball for hanging baskets and potted plants.
  2. For standard container use, apply at a rate of around 5 g per litre of potting mix (light feeding) or 6 g per litre (normal feeding).
  3. Note longevity varies with temperature: at lower temps (≈ 16 °C) the tablets may last up to ~10–11 months, while at higher temps (≈ 26 °C) release will shorten to ~6–7 months.
  4. Store unused product in a dry, sealed bag.
