Nitrogen and Leaves

Nitrogen is the nutrient responsible for leaf growth. As such, some sadistic bonsai masters would restrict food from a plant during the spring growing season.

Taub's experiments were meant to determine the difference between low and high amounts of nitrogen feed in 19 species of grasses (1/10th strength and full strength of a complete nutrient product). It turned out there was a 34% increase in leaf mass; a 12% increase in the amount of leaves; but oddly, a 4% reduction in the size of those leaves.

I say feed, feed, feed.
