Kern County's summer heat is extreme by any measure, and it creates a specific type of tree stress that most property owners haven't seen explained: sun scald and heat-induced bark cracking. When temperatures stay consistently above 100°F for extended stretches — as they do every summer in Bakersfield — certain tree species experience bark tissue damage from intense radiant heat, particularly on the south- and west-facing sides of the trunk.
The result looks like vertical cracks or areas of sunken, discolored bark. On younger trees or recently transplanted specimens, it can be severe enough to girdle the tree if the cambium layer beneath is damaged. On more established trees, it creates entry points for fungal pathogens and insects, which is a secondary problem that compounds over the following seasons.
Species like ornamental plums, young oaks, and thin-barked trees are particularly vulnerable in Bakersfield's climate. Protective measures exist — appropriate mulching, trunk wrapping on new plantings, and strategic placement relative to afternoon sun exposure — but they're most effective when applied before the heat peaks, not after the damage appears.
Have you noticed any bark discoloration or cracking on trees in your Bakersfield yard during summer heat waves, or is this a new concept for you?
