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).
Peach trees bear fruit on shoots that grew the previous year. These 1-year shoots (fruiting wood) have one to three buds at each node. The smaller, center bud is a leaf bud accompanied by up to two larger, outer flower buds. Moderately intensive pruning is needed each year to force the tree to grow new limbs. Maintain tree height at 9 to 10 feet by heading back scaffold branches to an outward growing lateral.
