What to Cover Soil in Potted Outside Plants

If you have potted plants outside, you may be wondering what you should use to cover the soil in the pots. There are a few options that you can consider, each with their own advantages and disadvantages. In this article, we will explore some of the popular choices for covering soil in potted outside plants.

1. Mulch

Mulch is a popular choice for covering soil in potted outside plants. It helps to retain moisture in the soil, prevents weed growth, and can even add nutrients to the soil as it breaks down. There are many different types of mulch available, including wood chips, straw, and shredded leaves.

One thing to consider when using mulch is that it can attract pests such as snails and slugs. You may also need to replace the mulch as it breaks down over time.

2. Gravel or Rocks

Another option for covering soil in potted outside plants is to use gravel or rocks. This can be a good choice if you want a more decorative look for your pots or if your plants are prone to soil-borne diseases. Gravel can also help to improve drainage in the pots.

However, one potential downside of using rocks or gravel is that they can become very hot in the sun, which can cause the roots of your plants to dry out. Additionally, they can be more difficult to remove than other coverings if you need to repot your plants.

3. Moss

Moss is a natural covering that can be used to cover soil in potted outside plants. It helps to retain moisture in the soil, prevent runoff, and can even impart a natural look to your pots. Additionally, it helps to control soil erosion.

One thing to consider when using moss is that it can be difficult to establish and can require frequent watering to maintain. It can also be more difficult to clean out of your pots if you need to repot your plants.

4. Synthetic Coverings

Finally, you may consider using synthetic coverings such as plastic sheeting or landscape fabric to cover the soil in your potted outside plants. These materials can help to retain moisture in the soil, prevent weed growth, and improve drainage.

However, one potential disadvantage of using synthetic coverings is that they can be less biodegradable than natural materials such as mulch or moss. They can also be less aesthetically pleasing and may require more effort to clean out of your pots if you need to repot your plants.

Conclusion

When it comes to covering soil in potted outside plants, there are many options to consider. Choose a covering that best meets the needs of your plants and fits with the look you desire for your outdoor space. And don't be afraid to experiment with different coverings to see which ones work best for you.
