How to care for Cutleaf Philodendron, Lacy Tree Philodendron (Philodendron bipinnatifidum)
Quick facts
- Water roughly every 7 days
- Light: Lots of bright light
Overview
Philodendron bipinnatifidum is a stunning tropical plant known for its large, deeply lobed, and dramatic foliage. It's a vigorous grower that can eventually form a tree-like habit, making it a spectacular statement piece for any indoor jungle. This philodendron brings a lush, exotic feel to your home with its unique, architectural leaves.
Watering
Water thoroughly when the top 2-3 inches of soil feel dry to the touch. Allow excess water to drain completely to prevent root rot. Reduce watering frequency slightly in cooler months. Signs of underwatering include drooping leaves, while yellowing leaves can indicate overwatering.
Light
Prefers bright, indirect light. Direct sunlight, especially harsh afternoon sun, can scorch its delicate leaves. An east-facing window or a spot a few feet from a south or west-facing window is ideal. It can tolerate medium light, but growth may be slower and leaves less vibrant.
Soil & potting
Use a well-draining potting mix that retains some moisture. A good blend includes peat moss, perlite, and orchid bark. Ensure the pot has drainage holes to prevent waterlogged soil, which can lead to root diseases.
Fertilizing
Feed your plant during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength every 2-4 weeks. Do not fertilize during the fall and winter months when the plant's growth naturally slows down.
Seasonal care
In spring and summer, increase watering and fertilizing as the plant actively grows. In fall and winter, reduce both watering and feeding. Monitor for potential pests and adjust humidity if necessary, especially in dry indoor environments.
Common problems
Root rot is a risk with overwatering; ensure good drainage and allow soil to dry slightly between waterings. Spider mites and mealybugs can sometimes infest the plant; treat with insecticidal soap or neem oil. Yellowing leaves often indicate overwatering, while brown, crispy edges suggest low humidity or too much direct sun.
Frequently asked questions
- Why are my Philodendron bipinnatifidum leaves turning yellow?
- Yellowing leaves are often a sign of overwatering. Ensure the soil is drying out slightly between waterings and that the pot has good drainage. It can also sometimes indicate a lack of nutrients or insufficient light.
- How do I encourage faster growth for my Lacy Tree Philodendron?
- Provide consistent bright, indirect light, regular watering (allowing soil to dry slightly), and fertilize during the growing season. Increasing humidity can also help promote more vigorous growth.
- What kind of pot should I use for Philodendron bipinnatifidum?
- Choose a pot that is at least 2 inches larger than the current root ball, with ample drainage holes. Terracotta pots can help soil dry out faster, which is beneficial for this plant if you tend to overwater.
- Can Philodendron bipinnatifidum tolerate low light conditions?
- While it can survive in low light, its growth will be significantly slower, and the leaves may not develop their full characteristic shape or color. It thrives best in bright, indirect light.
- How often should I repot my Cutleaf Philodendron?
- Repot your plant every 1-2 years, or when you notice roots emerging from the drainage holes or the plant becoming root-bound. Spring is the ideal time to repot.
