Plantacote® Top K 4M

Double the Potassium, Half the Nitrogen: 120 Days of Engineered Plant Stability

Plantacote® Top K 4M is ideal for potassium-loving, low-nitrogen crops with medium growth cycles, making it perfectly tailored for perennials, alpines, ornamental grasses, hardy nursery stock, and herbs.

Each granule delivers a high-potassium, restricted-nitrogen formula enriched with essential nutrients to ensure compact growth, intense flower coloring, and superior stress resilience.

K-Focused Precision for Container Culture

This low-nitrogen, high-potassium formula prevents elongated growth in pots, delivering exceptional structural strength and a compact habit to container-grown ornamentals, perennials, and alpines.

Enhanced Herb Quality & Essential Oils

For potted herbs, the restricted-nitrogen formula prevents watery growth, leading to higher dry matter content and more concentrated essential oils.

Maximum Wood Maturation & Frost Hardiness

Provides the ideal 1:2 N:K ratio to accelerate shoot lignification and wood maturation, perfectly preparing outdoor container crops and nursery stock for winter frost.

Incorporation

Plantacote® Top K 4M is evenly mixed into the growing media before potting.

Dibbling

The product is placed on the bottom of a planting hole, lightly covered with media before putting the plant into the hole.

Topdressing

The granules are applied to the surface of the substrate. We recommend placing them close to the watering system for best results.

Attention

Please consider, these are general recommendations which require adjustments in case of specific situations. All dosages are based on unfertilized media; reduce them if other fertilizers are used.

We recommend testing on a small scale first before changing your standard cultivation practice. Since circumstances can vary and as the application of our products is beyond our control, Plantacote® cannot be held responsible for any adverse results.

Controlled Release Temperature Factor: The rate of nutrient releases can vary according to the temperature of the substrate: 4M is determined at 21°C, 15-16°C results in 4-5M and 26-27°C in 2-3M.
