Ideal Temperature Range for Norway spruce

(Picea abies)

Norway spruce, also known as Common spruce

The norway spruce is native to regions of Europe with cool to cold climates. It prefers a temperature range of 32 to 90 ℉ (0 to 32 ℃) and can withstand temperatures as low as -40 ℉ (-40 ℃). In the summer, it benefits from cooler temperatures and moderate humidity. In the winter, it can tolerate frost and snow as long as it is not exposed to extreme freezing temperatures for extended periods.

Temperature Essentials for Norway spruce

Regional wintering strategies

Norway spruce is highly cold-tolerant and does not require additional frost protection measures during winter. However, before the first freeze in autumn, it is recommended to water the plant generously to ensure the soil remains moist and enters a frozen state. This helps prevent drought and water scarcity for the plant during winter and early spring.

Signs of Low and High Temperature in Norway spruce

Symptoms of Low Temperature in Norway spruce

Norway spruce is extremely cold-tolerant, but the winter temperature should be maintained above -40°C. If the temperature drops below this threshold, although there may not be any noticeable changes during winter, the branches may become brittle and dry during springtime, and no new shoots will emerge.

Solutions for Low Temperature in Norway spruce

In spring, prune away any dead branches that have failed to produce new leaves.

Symptoms of High Temperature in Norway spruce

Norway spruce is not tolerant to high temperatures. When the temperature exceeds 32°C, it may experience significant leaf drop, and in severe cases, the entire plant may wither and die.

Solutions for High Temperature in Norway spruce

Trim away the sunburned and dried-up parts. Move the plant to a location that provides shade from the midday and afternoon sun, or use a shade cloth to create shade. Water the plant in the morning and evening to keep the soil moist.
