[audio]http://sound.yywz123.com/tingbbs/voa/voa20110906.mp3[/audio]With a newly planted tree, the roots have not yet spread out from the root ball. The root ball can become dry faster than the dirt around it. So put water on the area of the root ball and the surrounding soil until the roots become established.
对于一棵新种植的树，它的根尚未从根球中散开。根球会比它周围的土壤更快变干。因此，要在根部完全长成之前对根球和它周围的土壤浇水。
Once a tree is well established, water deeply instead of often. The amount of water needed depends on the tree and the soil.
一旦树长成了，就不用经常给它浇水，一次深浇就可以了。水量的多少取决于该树和土壤。
Clay soils hold water for longer periods while sandy soils hold less water. During the hottest season, a deep watering may satisfy a tree for anywhere from ten days to four weeks.
粘土可以长时间保持水分，而沙土能保持的水分就很少。在最热的季节，一次深浇可能会满足任何地方的树10天到4周的水分需求。
