Winter burn is one of the most commonly misunderstood conditions we see across the Main Line—particularly on broadleaf evergreens like Schip laurels (Prunus laurocerasus ‘Schipkaensis’). It often looks like a much more serious problem than it is, which is why homeowners assume their beautiful plants are in severe decline or even dying! In reality, winter burn is a very typical seasonal stress response rather than a fatal issue, and a simple assessment (found below) can help put homeowners’ minds at ease.
What Winter Burn Is — and Why It Happens
Winter burn occurs when plants lose moisture through their leaves during cold, windy conditions while the ground remains frozen, preventing roots from replenishing that moisture. This desiccation effect is especially pronounced in evergreen species that retain foliage year-round.
In Bryn Mawr and the greater Main Line region, several factors contribute to its frequency:
- Fluctuating winter temperatures (freeze-thaw cycles)
- Dry winter winds
- Periods of intense sun reflecting off snow
- Frozen soil limiting water uptake
Schip laurels, while hardy, are particularly susceptible because of their broad, waxy leaves, which continue to transpire even in winter.
How It Commonly Presents
Winter burn on Schip laurels typically appears as:
- Browning or bronzing of leaves, often starting at the tips or edges
- Leaf scorch on the side most exposed to wind or sun
- Sparse or patchy discoloration rather than uniform dieback
- Damage concentrated on outer or upper portions of the plant
This visual decline can be alarming and is frequently mistaken for:
- Root failure or plant death
- Disease or pest infestation
- Improper installation or poor soil conditions
“Winter burn is often misinterpreted as plant failure, when in reality it is a surface-level response to environmental stress. With broadleaf evergreens like Schip laurels, the foliage may appear compromised after a harsh winter, but the integrity of the plant is very often still intact. Given time, proper care, and a measured approach, these plants demonstrate remarkable resilience and a strong return to form in the spring.” – Gary Westlake, Sr. Landscape Architect for Terren Landscapes
How to Confirm It’s Winter Burn (Not Plant Loss)
These simple assessments can help you determine if your laurels are going to pull through or croak out: :
- Scratch test: Gently scrape a small section of bark—green tissue underneath indicates the plant is still alive
- Bud inspection: Swollen or green buds signal recovery potential
- Pattern recognition: Is damage limited only to exposed areas or is it present on the entire plant?
What to Do Next
Don’t dig it up! Patience and proper care are essential, and premature removal is one of the most common mistakes.
Best practices include:
- Delay pruning: until new growth begins—this allows you to clearly distinguish viable wood from damaged tissue
- Lightly prune: only the affected areas once the plant starts pushing new growth
- Deep watering in early spring: to support recovery
- Apply a balanced, slow-release fertilizer: to encourage regeneration
In most cases, Schip laurels will rebound significantly by late spring or early summer. So give them time, and they will turn a corner and green up in no time. In time, if the plant does look like its on its way out, give us a call and we can evaluate them, and if needed, recommend a replacement.
Preventing Future Winter Burn
For high-value landscapes, prevention is where thoughtful design and maintenance truly elevate outcomes:
- Strategic placement to reduce wind exposure
- Anti-desiccant sprays applied in late fall
- Proper fall watering before ground freeze
- Mulching to regulate soil temperature and moisture
A Refined Perspective
At Terren Landscapes, we view conditions like winter burn not as setbacks, but as part of the natural dialogue between climate and landscape. With the right expertise and a measured response, these moments become opportunities to reinforce plant health and refine long-term resilience.
Again, if you have a concern about your installed plants, we would be happy to evaluate them by photo or in person with one of our experienced horticultural professionals, and we will make any recommendations needed.
Next time you see brown leaf tips after winter, don’t dig – call us instead.
