HOW TO PLANT ELEPHANT EAR BULBS. The first step in planting elephant ear bulbs is digging a hole deep enough for the entire bulb to be planted about 1 inch beneath the soil line. When digging your hole, be sure to loosen the soil at the bottom allowing the roots to reach the water more easily.
Scuppers can also be provided as primary or secondary drainage points. Scuppers are rectangular openings in parapet walls that are a minimum of 4 inches in width and height ranging from 4 to 6 inches. If the scuppers are used as primary drainage, then they are applied flush with the roof level. If they are used for secondary drainage, then they should be a minimum of 2 inches above the roof level and a maximum of 4 inches above the roof level.
