Is it easy to take Forsythia cuttings and how and when is the best time to
do it? There's a lot of Forsythia plants in my area and some are a lot more
colourful than others, are they a different variety or are they looked after
better?

Yes.

When the flowers have finished and the plants have come into leaf.

There are several varieties of Forsythia, but what variation in the
amount of flowers produced occurs seems to be more a result of pruning
regimen than variety. (Not that I can tell the varieties apart.)
