When you order a wooden planter box from our factory, the most common question we hear is whether liners are included or sold separately. The short answer is: it depends on the product and your project needs. Here is the full, honest breakdown.

For our standard ready-to-ship wooden planter boxes, liners are typically included in the price. These are simple, black plastic or landscape-fabric liners that are pre-installed inside the box. They protect the wood from moisture and root damage while allowing drainage through pre-drilled holes. If you are buying a standard size from our catalog, you do not need to purchase a liner separately.

However, for our custom-size wooden planter boxes or large commercial projects, liners are sold separately. Why? Because custom boxes often require different liner thicknesses, materials, or drainage systems. We cannot preset a one-size-fits-all liner into a box that is built to your exact dimensions. In those cases, we offer a range of liner options—from heavy-duty PVC to breathable felt—that you can add to your order as an accessory.

Another scenario where you might want to buy liners separately is replacement. Over time, even a good liner can wear out, especially in harsh weather or high-UV environments. If you already have one of our wooden boxes but need a new liner, we will gladly sell you just the liner. You do not have to buy a new box. This is also helpful for gardeners who want to upgrade from a basic plastic liner to a more eco-friendly, biodegradable option.

Now, what kind of liners do we sell? We offer four main types:

1. Standard black plastic liners – economical, waterproof, very durable.

2. Non-woven fabric liners – allow better aeration, ideal for vegetables and herbs.

3. Food-safe EPDM rubber liners – perfect for edible gardens, UV-stable and puncture-resistant.

4. Custom multi-layer liners – with built-in drainage spacers or root barriers for high-end projects.

Pricing is simple. If a liner comes with your standard box, its cost is already reflected in the box price. If you buy a liner separately, it is priced based on material, thickness, and size. We always recommend sending us your box’s interior dimensions so we can quote an exact fit. No guesswork, no wasted material.

One important tip: always measure the inside of your wooden planter box before ordering a liner separately. The liner should sit slightly loose to allow for expansion and contraction of the wood. A too-tight liner can tear when the wood swells after rain. Our factory team can help you calculate the perfect liner size if you provide your box’s length, width, and depth.

So, to answer your question directly: for standard orders, yes, liners come with the box. For custom orders and replacement needs, yes, we sell liners separately—and we even encourage it because it gives you more control over quality and fit. If you are unsure which route to take, simply contact our sales team with your order details. We will tell you instantly whether your box includes a liner or whether you should add one to your cart before shipping. Either way, you will never have to worry about your wooden planter box failing from moisture damage. We design every box and liner to work together, even when purchased on separate occasions.
