thread-leaf sundew

Thread-leaf sundews should be watered gently using distilled or demineralized water. Watering should only be done when the surface of the soil is dry to the touch. During the growing season, which is typically during the summer months, the soil should be watered roughly once per week. During winter dormancy, which typically occurs from late autumn to early spring, the soil should be watered less often, around every 2-4 weeks.

Thread-leaf sundews (Drosera filiformis var. filiformis) require specific amounts of light in order to flourish. They do best in full sun, with at least 6 hours of direct sunlight per day. During the late spring and summer months, when the sun is strongest, they may benefit from some afternoon shade to avoid sunburn. During the winter months, sun exposure should be minimized, as this plant will become dormant and will not need as much light.

Thread-leaf sundews should be pruned often, usually after they flower in spring and then again in late summer or early fall if needed. To properly prune this plant, use sharp, sterile shears to snip off any dead, wilted, or damaged stems just above the soil level, or just below a healthy, thriving stem or node on the plant. For those stems or plants that get too tall, pinch or snip off the tallest parts of the main stem and the uppermost branches. This will encourage dense growth and keep the plant from getting too leggy and unwieldy. Removing dead, decaying leaves will also allow more light and air flow to the base of the plant to further encourage growth. Pruning the thread-leaf sundew regularly will reduce the risk of the plant becoming diseased or infested with pests.
