Philodendron hastatum, also known as the silver sword philodendron, can be a great addition to a terrarium. Here are a few things to consider when growing this plant in a terrarium:
Lighting: Philodendron hastatum requires bright, indirect light to thrive. Placing your terrarium in a location that receives filtered sunlight, or using artificial grow lights, can help provide the necessary light.
Humidity: This plant requires high humidity levels to thrive. Terrariums can provide a humid environment, but it's important to ensure that the terrarium is well-ventilated to prevent the growth of mold and other issues.
Soil: Philodendron hastatum prefers well-draining soil that is rich in organic matter. A mixture of peat moss, perlite, and orchid bark can provide the necessary drainage and nutrients.
Watering: Water your Philodendron hastatum when the top inch of soil feels dry to the touch. Be careful not to overwater, as this can lead to root rot.
Size: Philodendron hastatum can grow quite large, so it's important to choose a terrarium that will allow for adequate growth. A larger, taller terrarium with plenty of space can be a good option.
Overall, Philodendron hastatum can make a beautiful addition to a terrarium if provided with the proper conditions.
