In the UK weld is considered a weed that needs to be got rid of as quickly as possible - well so it seems whenever I find a stand of it flourishing.
A few weeks ago I spotted the most enormous stand of weld - but not ready to pick, so I patiently waited a few weeks and then went back, oh no, virtually all gone! I couldn't believe it, almost all of it had been strimmed away by the local council. Fortunately they didn't bother to go round the edges very well so we have manged to crop some for the coming year.
An hour spent going round the area yielded
This was tied up in bundles like this
These were tied onto a "sheila maid" under the dye house canopy
Then lifted up to spend a few weeks drying before we chop it up ready for use!
