This is a picture of three Kale
plants - in January 1999 - all planted from the same punnet at the same time
- August 1998. The front one was sprayed with 'Pest Protection (PP)' while the
one I am holding was sprayed with a 'Flowering Spray'. The third - in the middle
back- was initially sprayed with 'Pest Protection' but had subsequently been
sprayed with the 'Flowering Spray' and can now been seen to be beginning to
be going off to seed. The 'Pest Protection plant' in the front did not go off
to seed until the end of the second season. Another kale plant in another part
of the garden which was sprayed with 'PP' did not go off to seed at all and
eventually died of exhaustion at the end of the third season.
