There're several ways to propagate herbs such as laksa leaves, basil, dill and mint.
One tried and tested method is to put the cutting in water for a few days until the thread-like roots form and you can plant them in the ground. Be careful of breeding mosquitos. So change the water frequently. You can also put a cover of aluminium foil over the mouth of the bottle, and poke holes on the foil where the stems go through to be extra careful.
The length of time the soaking takes, depends on the size of the plant. Generally the same principle applies for planting curry leaf and even "moses in a basket".
Tiny whiskers like roots forming from the dill plant. Placed in a vase, it can be a pretty bathroom decoration.
