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.
In the northern half of the country, you can regularly fertilize it once, in June, using 1 cup of manure, compost, cottonseed meal. You can also use a general purpose chemical fertilizer per label directions. One application per year is fine. In the lower half of the country, you can fertilize in May and June.
