Trees / Cash Flow - Trees spend their money five ways: growth, maintenance, exudates, reproduction, and storage for defense. Remember, You can have a full gas tank, but if your battery is dead, you will not start. Trees store their money in the symplast. As the symplast decreases, so does storage space. As Storage of energy reserves decrease, so does the defense potential. Pathogens seem to know this very well. You can cut a Christmas tree in December. In April it can be green and look like it maintains a healthy symplast. But, it (symplast) will have a serious problem. Insects and fungi "seem to know" when the curve is only downward.
