Growth—

Alnus jorullensis is a plant of tropical montane forests, where temperatures are cool, with abundant rainfall. They are also found in high-elevation, open, oak-pine and fir woodlands in Mexico[1]. Grows best in a sunny position, but is somewhat shade tolerant[2]. Prefers a heavy soil and a damp situation, but it succeeds in ordinary garden soil[3]. Grows well in heavy clay soils[3]. Tolerates very infertile sites[4]. The tree responds well to coppicing[5]. This species has a symbiotic relationship with certain soil micro-organisms, these form nodules on the roots of the plants and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[4].
