I have been growing outdoors in soil for about forty years.........for the last 35 years I have never defoliated again.
Five years of experimenting and listening to "advice" from other growers, proved to me that defoliation is just not right.
Every leaf is a solar factory that makes energy for the plant.
More leaves = more energy being made = more potential growth........
or to put it another way........
Less leaves = less energy being made = less potential growth.
During those last forty years, I am yet to see a healthy plant that gets rid of its own healthy, green, energy producing leaves for any reason.
It is only humans who think they know better than Milllenia of evolution that produced a plant that is at the pinnacle of perfection and effectiveness.
Over the last fifteen years, I have become a big fan of moderate "lollipopping" though.
