Two different supporting sticks and potting media were used to evaluate the growth of arrowhead plant (Syngonium angustatum Schott), in a completely randomized block design, in a factorial scheme (2 x 2) with six replicates, and three pots per plot. There were evaluated the (1) commercial substrate (SC) as potting medium, with fern tree supporting sticks (X); (2) commercial substrate as potting medium (SC), with coconut mesocarp supporting sticks (MCT); (3) commercial substrate and coconut mesocarp (SC+MCT) (1:1) as potting medium, with fern tree supporting sticks (X); (4) commercial substrate and coconut mesocarp (1:1) as potting medium (SC+MCT), using coconut mesocarp supporting sticks (MCT). Plant height or length, stem diameter, number of nodes and of leaves, leaf area, subterranean root volume and nutrient contents were evaluated. The best results for the morphological characteristics were observed in plants grown under MCT supporting sticks and the SC+MCT potting medium; nevertheless the highest leaf N content was observed in plants grown under MCT supporting sticks and SC potting medium. The treatment with fern tree supporting sticks and SC+MCT potting medium was the least adequate one for growing Syngonium angustatum and presented the lowest values for all variables studied.
