Do Cedar Planter Boxes Need To Be Sealed?

Cedar planter boxes do not necessarily need to be sealed, but it can be beneficial to do so. Cedar is naturally resistant to rot, decay, and insect damage, so it is already a durable and long-lasting material for outdoor use.

However, sealing cedar planter boxes can help to extend their lifespan even further by providing an extra layer of protection against moisture and UV damage.

If left unsealed, cedar planter boxes will eventually weather to a silvery gray color over time. While this can be an attractive look for some, sealing the box will help to maintain its original color and prevent it from fading or discoloring.

Sealing the cedar can also help to prevent the wood from splitting or cracking, which can occur over time as a result of exposure to the elements.

Overall, while it is not strictly necessary to seal cedar planter boxes, it is a good idea to do so if you want to maximize their lifespan and keep them looking their best over time.

There are a variety of sealants and finishes available that can be used on cedar, including oils, stains, and varnishes, so it’s worth considering which option is best for your specific needs and preferences.

What type of sealer can be used in cedar planter boxes?

There are several types of sealers that can be used on cedar planter boxes, each with its own benefits and drawbacks. Here are a few options:

Linseed oil: Linseed oil is a natural sealer that can penetrate the wood and provide long-lasting protection against moisture and UV damage.

It can also enhance the natural color and grain of the cedar. However, linseed oil can take a long time to dry and may need to be reapplied periodically.

Tung oil: Tung oil is another natural sealer that can provide a durable, waterproof finish for cedar planter boxes. It dries more quickly than linseed oil and can also enhance the wood’s natural beauty.

However, tung oil can be more expensive than other sealers and may not be as widely available.

Water-based sealers: Water-based sealers, such as acrylic or latex sealers, are a popular option for cedar because they dry quickly and are easy to clean up. They also provide good protection against moisture and UV damage.

However, water-based sealers may not penetrate the wood as deeply as oil-based sealers, and may not be as durable in the long term.

Clear wood sealer: A clear wood sealer is a popular option for cedar planter boxes because it allows the natural color and grain of the wood to show through while providing protection against moisture and UV damage.

Clear wood sealers are typically easy to apply and dry quickly, but they may not be as durable as some other sealers.

Varnish or polyurethane: Varnish or polyurethane can provide a very durable and long-lasting finish for cedar planter boxes, but they may also be more difficult to apply and may require more preparation than other sealers.

They can also create a glossy finish that may not be ideal for some applications.

Will the cedar planter box rot if not sealed?

Cedar wood has natural properties that make it resistant to rot and decay, due to the presence of natural oils and compounds. However, without any kind of sealant or preservative, cedar planter boxes may eventually rot over time.

Moisture is the primary factor that can cause cedar wood to deteriorate, and planter boxes are especially susceptible to moisture since they are constantly exposed to water and soil.

Over time, this moisture can cause the wood to swell, warp, and eventually decay.

A sealant or preservative can help to protect the cedar wood by reducing its exposure to moisture and preventing fungal growth.

By applying a sealant or preservative, you can help to prolong the life of your cedar planter box and maintain its appearance over time.

It’s important to note that even with a sealant or preservative, cedar planter boxes will eventually degrade and need to be replaced.

However, with proper care and maintenance, you can help to extend the lifespan of your cedar planter box and enjoy its natural beauty and functionality for many years to come.

Preserving a cedar planter box involves several steps to protect the wood and maintain its appearance over time.

Cleaning the cedar planter box periodically is one way to preserve its condition.

Before applying any sealant or preservative, clean the cedar planter box thoroughly to remove any dirt, grime, or debris.

Use a brush or cloth to scrub the surface with a mild detergent and water solution, then rinse thoroughly and allow it to dry completely.

Applying a sealer is also essential to keep the cedar planter box in good condition, choose a sealant or preservative that is designed for use on cedar wood and apply it according to the manufacturer’s instructions.

This will help to protect the wood from moisture, UV damage, and insect infestations. Consider using a natural product like linseed oil or tung oil, or a clear wood sealer.

Cedar planter boxes may need to be resealed or recoated periodically to maintain their appearance and protection.

The frequency of reapplication will depend on the type of sealant used, the climate and weather conditions, and how often the planter box is exposed to water and sunlight.

Check the box regularly for signs of wear and tear, and reapply the sealant as needed.

To prolong the life of your cedar planter box, consider placing it in a protected area away from direct sunlight, heavy rain, and extreme temperatures.

You may also want to use a tray or liner inside the box to prevent soil and moisture from coming into direct contact with the wood.
