Transitioning your Snake Plant outside involves gradually increasing its exposure to sunlight to prevent leaf burn. Start by placing it in a shaded outdoor area and slowly move it to a sunnier spot over a couple of weeks. Ensure the soil is well-draining, as Snake Plants are susceptible to root rot in overly moist conditions. With minimal care, your Snake Plant will continue to be a resilient and attractive addition to your outdoor space!
