Should you put a liner in a planter box?

As an experienced gardener and landscaper, I highly recommend putting a liner in a planter box. While it may seem like an extra step, lining a planter can provide numerous benefits and help ensure the longevity of your planters.

1. Moisture Control: One of the main reasons to use a liner is to control moisture levels within the planter. When you water your plants, the excess water can seep through the drainage holes and lead to waterlogging or damage to the planter material. A liner acts as a barrier, preventing water from directly contacting the planter. This helps maintain proper moisture levels for your plants and prevents any potential damage to the planter itself.

2. Protection from Rot: Many planters are made of wood, which is susceptible to rotting when constantly exposed to moisture. By lining the planter, you create a protective barrier that prevents the wood from coming into direct contact with the soil and excess water. This can significantly extend the lifespan of your planter box.

3. Weed Prevention: Lining a planter can also help prevent weeds from growing in the soil. Weeds can quickly take over a planter and compete with your plants for nutrients and water. By using a liner, you create a physical barrier that inhibits weed growth, allowing your plants to thrive without the added competition.

4. Easy Maintenance: Lined planters are generally easier to clean and maintain. The liner can be easily removed and cleaned separately, preventing any dirt or debris from accumulating in the planter itself. This can save you time and effort in the long run.

Now that we understand the importance of lining a planter box, let’s discuss how to do it effectively.

1. Choose the Right Liner: There are various types of liners available, including plastic, burlap, or even coconut coir. Consider the material that best suits your needs and the overall aesthetic of your planter.

2. Measure and Cut: Measure the dimensions of your planter and cut the liner material to fit accordingly. It’s essential to leave some excess material to ensure full coverage.

3. Position the Liner: Place the liner inside the planter, ensuring it covers the bottom and sides completely. Smooth out any wrinkles or folds, ensuring a snug fit.

4. Secure the Liner: Depending on the type of liner and planter, you may need to secure the liner in place. This can be done using staples, adhesive, or even by folding the excess material over the planter’s rim.

5. Add Drainage Holes: While the liner helps control moisture, it’s still important to provide proper drainage for your plants. Punch or cut holes in the liner at regular intervals to allow excess water to escape.

By following these steps, you can effectively line your planter box and reap the benefits of improved moisture control, protection from rot, weed prevention, and easy maintenance. Remember to choose the right liner material and regularly check for any signs of wear or damage to ensure the longevity of your planters.
