Features
Poinsettia is developed specifically for winter forcing cycles of poinsettias in greenhouse production. The medium-coarse structure — built from Baltic blonde peat 10–40 mm and German black peat 0–20 mm, with wood fiber and perlite — maintains consistent drainage even after 6–8 weeks of intensive irrigation. This reduces the risk of root rot.
Integrated expanded clay prevents substrate compaction during repeated irrigation cycles. It keeps porosity stable through the December sales window. The PG Mix starter fertiliser is calibrated with NPK 11-19-24+ — high in phosphorus and potassium — to support bract development and colour intensity. These are key commercial factors for this crop.
Poinsettia is suitable for pots from Ø 14 cm upward, the standard format for poinsettias sold through florists and retail chains. Selected peat from Baltic and German origins, consistently from the same fields, ensures lot-to-lot quality continuity.
