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. Once the number of required drains for the area is determined, the size of the drain inserts and plumbing should be established.
Drains that are blocked or are at high points on the roof. Ponding on flat roofs has a number of implications including reduced life expectancy of the roof, structural damage, leakage and possible vegetation growth. Water on the roof is your first clue that there is a ponding problem. Dirt, algae and vegetation are other indications. Look at the roof slope and evaluate the drainage opportunities for water to escape. Have emergency secondary drains, where an interior drainage system is used. This is often in the form of scuppers through parapet walls. The scupper drains are 2 inches above the low point of the roof so that they do not act as primary drains.
