spider lily

Spider lilies should be watered deeply once a week. Water until the soil is completely moistened and allow the top inch of soil to dry out between waterings. During extended dry periods, increase watering frequency to every 5 days. Spider lilies should not be overwatered, as this can cause root rot. If you are unsure about the soil's moisture level, stick your finger into the soil up to your first knuckle. If it's dry, it is time to water.

The spider lily (Tradescantia virginiana) needs moderate amounts of sunlight for proper growth. It should be exposed to 4-6 hours of direct sunlight each day for best growth and flowering. However, the sunlight should be filtered through a sheer curtain or thin fabric, as its leaves can get scorched if exposed to full afternoon sunlight in summer. In spring and summer, spider lilies should not be placed in full sun but in a mostly shaded spot, to avoid direct sun exposure during the hottest parts of the day. When planting outside in summer, provide some afternoon shade, so that the plants do not suffer from too much direct sunlight.

Spider lilies should be pruned in early spring just before new growth appears. Prune by cutting back the tip of each stem, cutting just above a node. This will encourage fuller and healthier growth. After pruning, any dead, damaged or diseased leaves should be removed. Cut back spent flower stalks to prevent seed formation and help the plant's energy go towards root development. Spider lilies respond well to a light pruning so you do not need to be overly aggressive with the pruning.
