Tree & Shrub
Substrates
Trees grow deep, expansive roots that need a solid, lasting foundation. A good substrate provides aeration, slow-releasing nutrients, and a stable water balance to support steady development without compaction.
- Deep aeration channels for unrestricted root expansion.
- Slow-decomposing organic matter for consistent nutrient supply.
- Well-draining composition to prevent water buildup
- Adjusted pH levels to suit different species.
- Beneficial microbes to improve nutrient uptake and soil health.
Leafy plants like lettuce, spinach, kale, basil, parsley, and cabbage require continuous vegetative growth rather than flowering. Their substrates must provide a steady supply of nitrogen to support leaf development while maintaining the right balance of moisture retention and aeration to sustain healthy growth. Excess phosphorus or potassium can disrupt this balance, triggering premature bolting, which reduces yield.
- Require continuous vegetative growth rather than flowering.
- Thrive with high nitrogen availability to support leaf development.
- Need moisture-retentive yet well-aerated substrates
- Excess phosphorus or potassium can trigger premature flowering
From tall canopies to dense shrubs
– we mix accordingly.
Trees and shrubs need a well-balanced substrate that supports
strong roots, steady growth, and long-term health. Deep-rooted
trees require structured, aerated mixes, while shrubs do best in
moisture-retaining substrates that nourish compact root
systems. We mix our formulas to match each plant’s needs, ensuring they stay healthy in any setting.
Peatman-selected substrates are mixed with precision, balancing water retention, aeration, and stability to meet the needs of your seedlings at every stage. We are agronomists, and we know everything-peat.
