Weld is a biennial and grows up to 5 feet in height. Itis very easy to grow, but it does not like a rich soild. I plant the seeds, which are fine and black, in February/March. I start harvesting in July, while the plant is still green. The colour is more concentrated on the leaves and seed capsules, the stalks don't have much colour. I chop the weld, add water and simmer gently for forty minutes. I get lemon yellow on mordanted silk and cotton. I used and old, dried up weld plant to dye the silk above, and obtained a dull colour. Weld is light fast, but dyed stuff should be washed in cold water as the dye is slightly soluble in hot water. |
