Primarily a botanical/plant pathology term. The apostrophe in 'witches'' is plural possessive (belonging to witches, suggesting a magical curse as the folkloric cause). Often hyphenated.
Dialectal Variation
British vs American Usage

Connotations
Identical technical connotations. The folkloric 'witch' association is equally residual in both varieties.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation as 'ведьмин веник' unless in a highly botanical context; it is not a common term.
- Do not confuse with general 'broom' (метла). The concept is specific.
- The plural possessive apostrophe (witches') is essential for the standard term.
Common Mistakes
- Misspelling as 'witch's-broom' (singular possessive) or 'witches-broom' (missing apostrophe).
- Using it as a general term for any bush or broom.
- Incorrect pronunciation stressing 'brooms' instead of 'broom'.

FAQ
Frequently Asked Questions

Often not. Management typically involves pruning out the affected limbs to reduce spread, or in severe cases, removing the tree.
From the old folk belief that such deformities were caused by witches or curses, and the growth's resemblance to a bundled broom.
Very rarely. It can be used metaphorically for any dense, tangled cluster (e.g., of wires), but this is not common.
