Christmas Tree Cultivation Under Pressure as Growers Face Climate Strain

As autumn sets in, Christmas tree growers are already feeling the impact of an unusually hot summer, with rising temperatures placing unprecedented stress on their crops.

Growers report that high temperatures have scorched young shoots, browned needles, and caused deformation of tree tops (leaders). New growth, which is still vulnerable, is especially hard hit. In some species, entire branches are showing burnt tips. The heat is also hampering lateral growth — meaning in some cases, trees aren’t filling out as they should.

Because Christmas trees take many years to mature, damage inflicted now can reverberate for seasons to come.

Supply Squeeze and Price Pressure

With losses mounting, growers are warning that fewer ideal trees — particularly tall specimens with clean, symmetrical shapes — may make it to market.

For consumers, that could mean thinner selections or higher prices than in past years.

Climate Change Intensifies the Threat

These heat-induced stresses are not isolated events, but part of a broader trend that threatens Christmas tree cultivation.

• Warmer soil and altered moisture regimes favour fungal pathogens like Phytophthora root rot, which thrives in wet, warm conditions.

• Mild winters and longer growing seasons allow pests to survive and expand their ranges, putting additional pressure on conifers.

• Some scientists are exploring more resilient species or genetic lines better suited to shifting climates — but change takes time.

What Can Growers Do (and What Can Consumers Expect)?

Growers are scrambling to adapt. Some are experimenting with fir species less sensitive to heat, improving irrigation strategies, and employing shading or windbreaks. Others are considering adjustments to planting schedules or spacing to reduce stress from drought.

For buyers, the advice is clear: shop early, be open about tree specifications (height, shape, species), and expect that the “perfect” tree may command a premium. In some regions, tall or flawless trees may sell out faster than ever.

A Christmas Challenge

Christmas may traditionally belong to snow and candlelight — but this year, the battle began in July and August.

For tree growers, it’s a race against time, temperature, and climate. For consumers, the risk is subtle but real: a more constrained, more expensive festive season.
