“…While there are studies exploring the root anatomy of these species (Liz Filartiga et al, 2021; Tenorio et al, 2014), we unravel the nitrogen uptake preferences (or lack thereof) of aerial roots of three Araceae species (Anthurium andreanum, Epipremnum aureum and Philodendron scandens ) in two humidities and show that the aerial roots consistently have a higher capacity for nitrogen uptake than their soil roots. Supporting other studies (Amitrano et al, 2019; Jeon et al, 2006; Tiwari et al, 2017) we found all three species grew more (both above and below ground) in high humidity, with the largest changes in aerial roots. These findings have wide ranging implications for our management of interior planting schemes to maximise plant health, air quality and human mental and physical health.…”

Heightened by the COVID‐19 pandemic there has been a global increase in urban greenspace appreciation. Indoor plants are equally important for improving mental health and air quality but despite evolving in humid (sub)tropical environments with aerial root types, planting systems ignore aerial resource supply. This study directly compared nutrient uptake preferences of aerial and soil‐formed roots of three common houseplant species under high and ambient relative humidities. Growth and physiology parameters were measured weekly for Anthurium andreanum, Epipremnum aureum and Philodendron scandens grown in custom made growth chambers. Both aerial and soil‐formed roots were then fed mixtures of nitrate, ammonium and glycine, with one source labelled with 15N to determine uptake rates and maximum capacities. Aerial roots were consistently better at nitrogen uptake than soil roots but no species, root type or humidity condition showed a preference for a particular nitrogen source. All three species grew more in high humidity, with aerial roots demonstrating the greatest biomass increase. Higher humidities for indoor niches, together with fertiliser applications to aerial roots will support indoor plant growth, creating lush calming indoor environments for people inhabitants.
