Detailed explanation-1: -Deep cracks indicate that a separation of the wood within a trunk or branch has occurred and the tree has become structurally weakened. If you find a crack, it is best to have it inspected by an arborist.

Detailed explanation-2: -Cracks in tree trunks can be one of the major indicators of an unstable tree. Most cracks are caused by improper closure of wounds or by the splitting of weak branch unions. They can be found in branches, stems or roots, and vary in type and severity.

Detailed explanation-3: -A well-developed crown with full leaves and good dark green color are indicators of a healthy tree (left). Discolored or browning leaves and dead branches on the top of the tree (right) are indicators of some type of stress – typically water stress due to drought or a stem injury.

Detailed explanation-4: -Unfortunately, if there is severe breakage at the base of the trunk, it will be hopeless to try to save it. Without branches or leaves, there will be no way for it to obtain enough nutrients for growth. The tree will have lost all the vital components and will eventually die despite the excellent responses to wounds.

Detailed explanation-5: -Wilting. Yellowing leaves. Brown and dying leaves and needles. Spots or blemishes on leaves, fruit, and/or bark. Fuzzy or moldy-looking patches. Holes in leaves. Dead, dying or dropping branches. Leaning tree. 29-Mar-2021
