Watering Hemlocks in Fall: Should You Avoid Watering Before a Frost?

Watering Before Frost Is Safe

There's no need to skip watering hemlocks when frost is forecast. In fact, adequate soil moisture going into winter helps prevent desiccation, a major cause of winter injury in conifers.

Best Practices

• Use soaker hoses or drip irrigation to water the root zone deeply.
• Apply water early in the day so foliage can dry before nightfall.
• Continue watering until the ground freezes.

Why It Matters

Hemlocks and other evergreens lose water through their needles all winter. Frozen soil prevents root uptake, so plants rely on stored moisture. Well-hydrated tissues resist winter burn better.
