Do snake plants need direct sunlight from windows?

Prof. Samuel Fitzgerald, Ph.D.Snake plants prefer to grow in bright indirect light, rather than direct sun or low light near windows. In their native habitat, they grow in filtered light conditions. If they receive direct southern sun exposure, they will often burn their leaves, causing them to become brown and irreparable. North-facing windows will significantly slow their growth. East-facing windows are the perfect area as they provide a gentle morning sun.
Window Direction Guide
- East-facing: Ideal gentle morning sunlight
- West-facing: Needs sheer curtains for afternoon protection
- South-facing: High risk of leaf scorching without filtering
- North-facing: Requires supplemental lighting for growth
Light Stress Indicators
- Brown crispy patches indicate sunburn damage
- Yellowing leaves signal excessive light exposure
- Leaning growth shows uneven light distribution
- Faded variegation means insufficient light levels
Seasonal Adjustments
- Move plants back from windows during summer intensity
- Rotate plants weekly in winter for even exposure
- Use LED grow lights during dark winter months
- Clean windows seasonally for maximum light penetration
For balanced light exposure, make sure to rotate your plants every month to avoid uneven growth and leaning. I routinely turn them 90 degrees each week to help maintain symmetrical leaf growth. For certain variegated varieties, turning them is even more important to conserve their occasional symmetrical patterns.
Take note of the indications low light has on your plants. Plants that are in shadows or dark corners will grow very slowly. The leaves may appear a darker green as chlorophyll builds up. If the leaves are stretched thin, this indicates a lack of light. I try to give these plants a little brighter light by moving them in increments weekly.
When necessary, provide supplemental natural light. Full-spectrum LED lights can be used for 6-8 hours per day during the dark winter months. Position your lights approximately 12 to 18 inches above the tops of the plants. I have timers for daily cycles to provide light consistently every day. I have been told and read material that this will stop etiolation during low-light months.
Shield your plants from direct and excessive summer sunlight. Sheer curtains can help diffuse the intense rays that come in the afternoon. Alternatively, consider moving your plants 3-5 feet back from south-facing windows. I use UV-filtering window films in my sunrooms since I cannot pull curtains. All of these recommendations will help prevent leaf scorch during the summer months, when sunlight is at its harshest.
