Just like biting your tongue accidentally while awake, you may do the same during sleep. A disproportionately large tongue or a crowded or misaligned set of teeth can result in excess tongue injury during wakeful time, as well as during sleep.
Fertilize your cedar hedge in the early spring when flowers and plants are blooming. Use a 30-10-10 water-soluble fertilizer on the soil around the hedge. Water the hedge immediately following the fertilizer application. Continue to water the soil until you can no longer see any fertilizer granules on the soil surface.
Take cuttings from white cedar trees in late fall, winter or early spring, when trees are fully dormant and sap is running very slowly. This will cause less injury to the tree and to the cutting itself. Plan for early morning for the slowest sap movement of all.
