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).
Remove any branches growing towards the center of so that the peach tree retains its open center. Also remove any small, thin shoots as these will not be able to produce healthy fruit. Avoid removing branches that are 18 to 24 inches in length. Prune any downward hanging branches or shoots growing horizontally.
