What Is the Ideal Temperature Range for evergreen wood fern?
Marginal wood fern is notably resilient to temperature fluctuations, thriving in both cold and heat. It can withstand frigid conditions down to -25℃ (-13℉) and endure heat up to 38℃ (100℉). This broad temperature tolerance makes it highly adaptable, though care must be taken during extreme weather. In cold snaps, signs of damage include browning fronds and stunted growth, while extreme heat may cause wilting and scorching. Protective measures such as mulching in winter and providing ample water and shade in summer are essential to maintain its health. Thus, marginal wood fern suits a variety of environments but requires vigilance during seasonal extremes.
