What kind of wood is best for planter boxes?
Wood Planter Boxes Cedar and redwood are your best options. Both are durable and rot-resistant. Pine and fir work equally well but lack the water resistance of cedar and redwood. So you’re planting boxes won’t hold up nearly as long. Using a sealant is one of the easiest and most effective ways to protect the interior of a wooden planter. Consider these options: Polyurethane sealant – Forms a protective, waterproof barrier. Marine varnish – Ideal for extreme weather conditions.Plastic sheeting works well to protect the wood. For a cheaper alternative, you could use an empty compost bag, just cut it open and staple the bag to the inside of the box. Treating the wood with a sealant, waterproof paint, or wood preservative will protect wooden planters from rotting.Synthetic materials like plastic, fiberglass, and metal are popular choices for outdoor planters. They are more durable and weather-resistant than natural materials and come in various shapes and sizes.
How do you keep wooden planter boxes from rotting?
The first thing you need to make sure of is that your planter box has enough drainage at the base. If it doesn’t, then you will need to drill a few holes in to allow for proper liquid drainage. Secondly, be sure to use a potting mix that has adequate drainage and is lightweight. Proper drainage is essential for keeping your plants healthy and vibrant when they are kept in planters. One easy way to make sure this happens is by adding drainage holes. These prevent excess water from causing root rot and other issues.Ensure Proper Drainage – If the planter does not already have drainage holes, drill small holes in the base to allow excess water to escape. Add a Drainage Layer – A layer of gravel, pebbles, or broken pottery at the bottom of the planter will improve drainage and prevent water from sitting against the wood.Any water that pools at the bottom of a planter can allow bacteria and fungus to form and cause root rot, which can be deadly. Though every plant owner should know their individual plant’s care and watering needs, drainage holes in a planter allow any extra water to seep out.
What to put in the bottom of a wooden planter box?
For permanent outdoor planters: Heavy base of gravel or rocks, then a mix of broken ceramic pieces and logs, topped with fabric and potting mix enriched with compost. For seasonal displays: Coarse wood chips, pinecones, and cardboard boxes crushed down, then fabric and potting mix. Preparing your planter Add a layer of gravel, broken pots, or large stones to the planter’s base for drainage. Then fill it with soil or compost suitable for the type of plants or vegetables you want to grow. Now it’s ready for planting!
How long does a wooden planter box last?
Pine is an inexpensive wood, but it can typically only be expected to last about 5 years, maybe 10 under the best conditions. Cedar, redwood, cypress, and hemlock are all types of wood that don’t decay or rot quickly, and they can be expected to last anywhere from 10 to 20 years. Choose naturally rot-resistant, untreated wood like cedar, redwood, or hemlock for long-lasting raised beds (10+ years). Avoid thin or pressure-treated boards, and use the thickest wood you can afford—ideally 2 inches thick.Redwood and cedar are more expensive but resist decay, so they last longer. Pine and fir will break down more quickly but are available at a fraction of the cost. Pressure-treated wood is also an economical option for improving the life of raised garden beds.
How do you waterproof the inside of a wooden planter box?
Using a sealant is one of the easiest and most effective ways to protect the interior of a wooden planter. Consider these options: Polyurethane sealant – Forms a protective, waterproof barrier. Marine varnish – Ideal for extreme weather conditions. Lining a wooden planter reduces direct contact between the soil and the wood, which helps prevent moisture damage and extends the life of the planter.
