What the studies tested
Results from growing trials, many of them in commercial greenhouses. They are not care instructions.
Care
Potting mix
In trials on two Philodendron species, cuttings in coco coir grew roots about as long as in the longest-rooting mixes (25–28 cm), while cuttings in pure sand or pure perlite made the shortest roots or leaves.
B IndirectMeasured on Philodendron domesticum and Philodendron erubescens
Propagation
In a winter glasshouse, keeping the rooting medium at 24 °C or warmer raised the rooting grade of heart-leaf philodendron cuttings after 7 weeks from 2.1 to 2.8 on a 1–4 scale.
