-17.8Â°C to -15Â°C. The new hardiness map is divided into nine major zones: the harshest is 0 and the mildest is 8. Subzones (e.g., 4a or 4b, 5a or 5b) are also noted in the map legend. These subzones are most familiar to Canadian gardeners.
Sweet stool: In general, a sweet odor to the stool is not worrisome. It could possibly be due to syrupy medications (which you say you are not taking) or due to not digesting sugars in the diet properly, which is unlikely if you are not symptomatic.
Black Stools (Not Sticky, No Odor). Other causes of black stool are iron pills or bismuth-containing medications (such as, bismuth subsalicylate or Pepto-Bismol). If the stool color is dark because of any of these medications, it is typically not sticky in texture and is not foul-smelling.
