Driftwood can be used to make various arts and crafts, including planters for flowers and vegetables. Driftwood planters, when treated and constructed properly make great indoor or outdoor planters that cost little time and money to create; most of your time will be spent looking for pieces of driftwood to use.
Collect pieces of driftwood. Try to find large pieces as well as small pieces, because you can make different types of planters from both. Look in your yard after floods or on other people's properties, provided you have permission. Do not collect driftwood from local parks, as it is illegal to even pick flowers from such places.
Store the driftwood pieces in a dry place and allow the driftwood to dry out completely before you begin to transform the pieces into planters. You may need to use a dehumidifier to speed up the drying process.
Use a drill and drill bits to drill out holes in the large pieces of driftwood. The holes will be used to house small plastic or terracotta pots. Find the pots first, to ensure that the holes are big enough for the pots to fit. You may need to drill several holes that connect, unless you have a large drill bit.
Avoid drilling completely through the piece of driftwood, unless you drill a tapered hole that the pots will not fall through. You may want to use a knife or sandpaper to carve the hole a little bit larger on the sides.
Glue small pieces of driftwood onto the outside of larger plastic or terracotta flowerpots. Leave gaps or cover the pot completely with driftwood pieces.
Use a paintbrush to apply water sealant to the driftwood to protect the planter from water damage, whether used inside or outside. Allow the sealant to dry according to package directions and then apply two or more coats of clear wood stain or polyurethane to further protect the driftwood planter.
