In the Delta state you are sound asleep. Delta waves are the slowest of all five brainwave frequencies and range between 0-4 Hz. Slow Wave Sleep or SWS, is the deepest of sleep states and it plays a vital role in health and well being. During this phase of the sleep cycle, the brain begins producing very slow, large Delta waves.
Pruning Tips. 1  First dormant season (a year after you plant the tree): Remove the central leader and direct the tree growth toward three or four strong scaffolds. 2  Second dormant season: Prune away fast-growing new shoots but leave twig growth, which will be the fruit-bearing wood (on most peach trees).
To stimulate new growth, prune about 40 percent of the shoots each year. Prune the ends of the scaffold branches to keep them at a good height for picking peaches. A peach-growing height of 7 feet is best, but of 8 to 9 feet tall is OK. Prune all gray wood within this zone.
