Introduction
Decorating your home garden or adding greenery in your indoor spaces is a great way to improve air quality and create a serene, calm environment. But choosing the right planter can be challenging, especially when it comes to metal planters. One important question you might ask is, what should I line a metal planter with? In this article, we will share tips, ideas, and different ways to line your metal planter to help you keep your plants healthy and your planter looking beautiful.
Why Line a Metal Planter?
Metal planters add a modern and sleek touch to your décor. However, if you directly plant your favorite flowers or herbs in a metal planter, it can damage the plants. Metal can get hot in the sun or very cold during winter, causing the roots to dry up or freeze. Lining your metal planter will protect your plants and extend their life while also helping to filter excess water.
Use a Plastic Liner
If you have a metal planter with drainage holes, you can use a plastic liner to line the inside of the planter. Simply fit the liner inside the metal planter and trim the edges. Then, add soil and your favorite plants inside the plastic liner. This way, you can easily remove the plastic liner and clean it when needed. A plastic liner also will help contain water and prevent it from spilling, especially when watering your plants.
Use a Coconut Liner
A coconut liner is a natural and sustainable option to line your metal planter. Coconut liners help retain moisture, which is an excellent feature for plants that require more water. These liners are also biodegradable, reducing environmental impact. A coconut liner is available in several sizes to fit your metal planter. You can also easily remove it and reuse it after it is dry.
Use Landscape Fabric Liner
Landscape fabric liners are sturdy and can be a good option for larger metal planters or when you live in harsh weather conditions. This type of liner helps control weed growth, provides aeration and drainage, and helps soil retain moisture. Landscape fabric liners come in different sizes and are relatively easy to clean by rinsing under clear water.
Use a Rust-Oleum Paint and Primer Spray?
If you do not want a liner, you can consider using Rust-Oleum Paint and Primer Spray specially made for metal surfaces. The spray evenly covers the planter and protects the metal from rust and corrosion. You can also add some design and color to your metal planter by choosing different shades and finishes. This option is simple, affordable, and environmentally friendly as it does not involve creating more waste with a liner.
Consider Adding a Layer of Gravel
Adding a layer of gravel to the bottom of your metal planter can provide extra drainage and prevent water from being retained. You can use small pebbles or rocks, or choose a specific kind of textured stone for a decorative effect. However, keep in mind that you still need to have a liner or a sealant to protect the roots from metal temperature changes and soil from leaking out.
Use a Waterproof Sealant
If you want to use a metal planter without a liner, you can seal the inside of the planter with a waterproof sealant. A sealant will protect the metal from rust, reduce any chemical reactions, retain moisture, and help keep the soil from spilling out. You can apply the sealant according to the instructions, but make sure you choose a product that is safe for plants and the environment.
Use a Plastic Bag
If you have a small metal planter or need a quick solution, you can simply line it with a disposable plastic bag. Fill the bag with soil and your favorite plants, and cut off any excess plastic around the edge. Although this is not a long-term solution, it can help you prolong the life of your plants and your metal planter with minimal effort and cost.
What to Avoid
Avoid lining your metal planter with moss, old cloth, or newspaper. These materials retain moisture and can quickly lead to root rot, which is detrimental to your plants' health. Also, avoid using untreated wood as a liner since it can rot and quickly deteriorate. Lastly, avoid using any paint that is not made for metal surfaces since this can be toxic for your plants and your safety.
Conclusion
Lining your metal planter might seem like an extra hassle, but it can help keep your plant healthy and your planter looking great. Whether you choose plastic, coconut, or landscape fabric liner, gravel or sealant, or any other creative option, make sure you research the products beforehand, so they fit your needs. A beautiful metal planter can be a perfect addition to your home, and with proper care, it can last for years.
