Plagron Seeding and Cutting Soil 25l
Sending a bag is €12.95 (Belgium) per bag, register on the site to see the shipping costs. Plagron Seeding and Cutting Soil 25 l is Plagron's dedicated propagation substrate — a fine, uniform mix of white peat, black peat, peat fibre and marl with an ultra-low EC and pH precisely calibrated for germination and rooting. Engineered for sensitive cuttings and seedlings that need a low-stress nutritional environment to establish quickly and uniformly. The powder-fine texture makes transplanting effortless without disturbing fragile root systems. Combine with Plagron Seed Booster Plus for difficult-to-root cuttings.

Plagron Seeding and Cutting Soil 25 l — Precision Propagation Substrate for Consistent Rooting Results
Propagation success rates are largely determined by substrate quality. Too much EC at the wrong moment, poor moisture distribution, or the wrong pH — any of these factors can suppress rooting in cuttings and seedlings before they even get started. Plagron Seeding and Cutting Soil 25 l removes these variables. Every component is selected for the single purpose of maximising rooting speed and uniformity in the most sensitive phase of cultivation. Pair it with other Plagron growing media for a complete substrate strategy from propagation through harvest.
Component Breakdown: Why Each Ingredient Matters
The effectiveness of Seeding and Cutting Soil comes from the precision of its formulation. White peat delivers lightweight, moisture-retentive structure that keeps the root zone consistently humid without waterlogging. Black peat adds structural stability over time. Peat fibre improves porosity and drainage, preventing compaction during repeated watering cycles. Marl buffers pH to the optimal range for seed germination and early root initiation. Together, these components create a substrate that is simultaneously forgiving and highly effective.
- White peat + black peat: balanced moisture retention and structural stability — the root-friendly foundation of the mix.
- Peat fibre: sustained porosity and drainage across multiple watering cycles — no compaction, no waterlogging.
- Marl: natural pH buffering at the optimal range for germination and first-stage root development.
- Ultra-low EC: zero salt stress on the most sensitive young root tissue — maximum rooting speed and uniformity.
- Fine, homogeneous texture: clean transplanting with minimal root disturbance when potting up.
Protocol: From Cutting to Established Plant
Fill your propagation tray or small pots with Seeding and Cutting Soil and insert cuttings or seeds directly — no pre-treatment required. For cuttings that root with difficulty, add Plagron Seed Booster Plus to the medium for targeted rooting stimulation. Once roots are visible outside the root ball, transplant into a pre-fertilised growing medium such as Plagron Grow-Mix and begin a standard feeding program. The powder-fine texture allows clean separation of the root ball at transplant without tearing or compressing the new root system.
Scaling Up: Why the 25 l Format Pays Off
For growers running regular propagation cycles or starting large numbers of cuttings simultaneously, the 25 l bag standardises conditions across every pot in a batch — same EC, same pH, same structure for every cutting or seedling. This consistency is what turns variable propagation results into reliable, predictable rooting rates. Combine with Plagron Power Roots to further accelerate root initiation and build a complete, reproducible propagation protocol.

How many cuttings or seedlings can I start with Plagron Seeding and Cutting Soil 25 l?
Twenty-five litres fills approximately 80–100 small 0.25-litre propagation pots, or 25–30 larger 0.8–1-litre pots for seedlings. This format is ideal for growers running multiple propagation rounds per season or starting large batches of cuttings simultaneously, eliminating the need to keep purchasing small bags and ensuring consistent substrate conditions across an entire batch.
When should I start feeding plants grown in Plagron Seeding and Cutting Soil 25 l?
Wait until roots are visible outside the root ball, or until transplanting into a pre-fertilised growing medium, before introducing supplemental feeding. Seeding and Cutting Soil contains balanced base nutrition for the early phase. Introducing high-EC nutrient solutions before the root system is established will stress young roots and reduce rooting success rates — the ultra-low EC of this substrate is its primary advantage for sensitive propagation material.
Is Plagron Seeding and Cutting Soil 25 l suitable for seed germination as well as cuttings?
Yes. The ultra-low EC and marl-buffered pH make this substrate equally effective for seed germination and cutting propagation. The fine, homogeneous texture distributes moisture uniformly across the tray, ensuring consistent germination conditions across all seeds in a batch — reducing the variance in germination timing that can make early plant management more complex.
What is the difference between Plagron Seeding and Cutting Soil and Plagron Light-Mix?
Seeding and Cutting Soil is engineered for the earliest propagation phase — cuttings and germinating seeds — with an ultra-low EC that eliminates salt stress during root initiation. Light-Mix is lightly pre-fertilised for one week and suited to plants that are already rooted and entering active vegetative growth. Use Seeding and Cutting Soil for propagation, then transplant into Light-Mix or Grow-Mix once plants are sufficiently established.
