Snake Plant with Sunburn (Sun Scorch)? Rare but Treatable
Sansevieria trifasciata
Sunburn or sun scorch is an environmental condition that occurs when plants are exposed to intense, direct sunlight beyond their tolerance level. This causes the breakdown of chlorophyll in the leaves, resulting in bleached, dried, and damaged foliage. The damage can happen rapidly, sometimes within just a few hours of exposure.
ð Symptoms
- âĒ Pale, bleached, or washed-out white areas on leaves
- âĒ Affected areas turn yellow, then brown, and become brittle
- âĒ Damage appears primarily on top leaves or sun-exposed surfaces
- âĒ Leaf edges become completely dry and crispy
- âĒ Underlying leaves remain unaffected
- âĒ Rapid onset of symptoms (within hours)
â Possible Causes
- â Abrupt exposure to bright, direct sunlight
- â Moving plants from low-light to high-light environments too quickly
- â Intense sun combined with dry soil conditions
- â Hot temperatures and high winds increasing water loss
- â Lack of gradual acclimation (hardening off)
- â Water droplets on leaves acting as magnifying lenses in bright sun
ð Treatment
Quick Fixes
Step 1
Immediately provide shade using umbrellas, cardboard, or shade cloth during hottest hours (10am-4pm)
Step 2
Give a deep watering in the early morning to reduce plant stress
Step 3
Remove completely scorched leaves to prevent rot
Step 4
Monitor daily and adjust shade as needed
Organic Treatment
Step 1
Move the plant to a shaded area or use shade cloth to block direct afternoon sun
Step 2
Prune away severely damaged leaves and stems to prevent disease
Step 3
Apply a thick layer of organic mulch (2-3 inches) around the base to retain soil moisture
Step 4
Deep water in the morning to help the plant recover from stress
Step 5
Wait one week, then apply liquid seaweed fertilizer to speed healing
Step 6
Gradually reintroduce the plant to sunlight over 2-3 weeks
ðĄïļ Prevention
- â Gradually acclimate plants to bright sun over 2-3 weeks (hardening off)
- â Start with full shade, then introduce 1-2 hours of morning sun
- â Keep plants out of direct sunlight during extremely hot days
- â Use sheer curtains or shade cloth to filter intense light
- â Water adequately, especially on hot and windy days
- â Water in morning or evening to avoid droplets during peak sun
- â Apply organic mulch to conserve soil moisture and reduce temperature
- â Provide temporary shading on extremely hot days

ð§ How to Water
Allow soil to dry completely between waterings. Water every 2-3 weeks in growing season, monthly in winter. Overwatering is the most common mistake - when in doubt, don't water.
âïļ Lighting
Adapts to most light conditions from low light to bright indirect. Avoid intense direct sunlight which can scorch leaves. Darker varieties tolerate low light better; variegated types need more light to maintain coloring.
ðŠī Ideal Soil
Use well-draining soil mix. Combine regular potting soil with coarse sand and perlite for optimal drainage. Ensure pot has drainage holes to prevent root rot.
