Why do different parts of the trunk turn black

The trunk turns black from below

The trunk begins to turn black due to sun and frost burns. During early spring, on sunny days, the bark without a protective whitewash becomes very hot. The nights at this time are still frosty, so there are sharp changes in temperature regimes that cause burns.

Trunk bark

Before the formation of wounds and cracks in the tree, black spots appear on the trunk. In places of their appearance, the bark acquires a characteristic shade, it can gradually darken. She becomes like a firebrand. These areas crack, flake and fall off, exposing the already black wood. In this case, it is necessary to carry out cleaning and disinfection with copper or iron sulfate. These areas should be well separated.

• White growths appear. The formation of white outgrowths on a garden culture indicates a serious infection by tinder fungi. They appear on dead wood through cracks in the bark.
• Cracks. After the trunk is blackened, wood and bark begin to crack. In this case, it is necessary to urgently clean up the culture to a healthy material and disinfect the wounds.

The bark on damaged areas cracks

It is recommended that the affected branches on the trunk be cut and burned so that the disease does not spread. If the root system is sufficiently developed, a new crown can grow in 2-3 years.
