One key difference between indoor and outdoor fiberglass planters<\/a> is whether or not they have drainage holes. Typically, indoor fiberglass planters will be sealed, and outdoor fiberglass planters will have drainage holes that allow water to seep out; both to avoid flooding a plant’s root structure and to protect the planter’s overall integrity. However, if you ordered a sealed planter and now need it to have drainage holes, here are step-by-step directions on how to drill holes in fiberglass planters.<\/p>\n\n\n\n

Materials Needed:<\/strong><\/h2>\n\n\n\n
    \n
  • Eye protection<\/li>\n\n\n\n
  • Safety mask<\/li>\n\n\n\n
  • Drill<\/li>\n\n\n\n
  • 1 inch spade drill bit<\/li>\n\n\n\n
  • Wet\/Dry Vacuum<\/li>\n<\/ul>\n\n\n\n

    How to drill holes in fiberglass planters<\/strong>:<\/h2>\n\n\n\n
      \n
    1. Place planter upright on a flat surface, and ensure the surface where you are drilling is protected. Do not flip the planter upside-down to drill holes, especially if it is painted as it might damage the finish.<\/li>\n\n\n\n
    2. Mark where you\u2019d like drainage holes in the planter interior. We typically recommend a minimum of two drainage holes. However, the total number of needed drainage holes will vary based on the size of the planter.<\/li>\n\n\n\n
    3. After marking your interior drainage hole locations, make sure that any holes drilled will not go through the \u201cfeet\u201d of the planter.<\/li>\n\n\n\n
    4. Place the drill bit on the mark, and gently let the drill carve into the fiberglass until you\u2019ve reached through the other side.<\/li>\n\n\n\n
    5. Use a wet\/dry vacuum to clear away any debris.<\/li>\n<\/ol>\n\n\n\n
      \"Showing<\/figure>\n\n\n\n

      A few notes:<\/strong><\/h2>\n\n\n\n
        \n
      • Use a \u00bd inch spade drill bit for smaller planter sizes.<\/li>\n\n\n\n
      • A good rule of thumb for the number of drainage holes needed is 3-4 holes for 36 inch planters, and 4-6 holes for 46 inch planters. However, consider the overall planter width and height before drilling. For example, though we recommend 4-6 drainage holes for a 46 inch planter, it might not be feasible to include that many drainage holes in a tall, skinny 46 inch planter.<\/li>\n<\/ul>\n\n\n\n

        Drilling drainage holes in a small number of fiberglass planters likely won\u2019t take up too much time. However, for larger planter quantities you\u2019ll save significant time by placing an order and selecting the \u201cadd drainage hole\u201d option.
