Can I Just Top off Potted Plants with More Soil?

Topdressing or adding a layer of fresh soil to your houseplants is not uncommon. Whether you have a newer plant or have had one for years, there comes a time when you need to add more soil to the pot. However, the question arises whether to add only a top layer or entirely change the soil. In this article, we will answer the question, "Can I just top off potted plants with more soil?"

What Happens Over Time?

When plants grow in pots, it often means that they have limited access to nutrients and water. As a result, the soil becomes compressed, reducing air circulation to the plant's roots. This can lead to root rot and other health problems for your plant. Over time, soil also loses its nutrients, making it necessary to add more. Also, in containers, soil can shrink gradually, especially if it's not high-quality soil, leaving a gap between the plant's roots and top surface.

Can I Just Top off the Soil?

The short answer is no. If you are only planning to add more soil to the top, it will not solve the problem of compacted soil, nutrient depletion, or air circulation issues. Your plant needs healthy soil that can keep its roots hydrated, aerated, and receive nutrients. Therefore, merely adding soil to the top will not address any of these issues, and the underlying problems will remain unresolved.

So What Should I Do?

If your plant is growing in a pot for more than a year, it's likely that it needs a complete soil change. A fresh blend of high-quality soil will provide your plant with essential nutrients and air circulation that it requires to grow healthy. It also avoids any pests or diseases that could live in the old soil. It's essential to choose a pot that is the right size for your plant and ensure that it comes with drainage holes to avoid waterlogging.

How to Re-pot Your Plant?

To change a plant's soil, take it out of its old container and examine the roots. If they are growing upward and wrapping around the pot, it's a sign that it's time for a more substantial container. Remove any debris or dead roots before placing the plant in its fresh soil. Firmly press the soil to avoid air pockets and give your plant a good watering. Place it in a well-lit area, and you'll notice it will start to thrive again.

Conclusion

To maintain the health of your potted plants, it's essential to know when you need to change the soil entirely rather than merely adding more soil to the top. Over time, soil can become compacted and nutrient-deficient, leading to root rot or even plant death if not resolved. While re-potting may require more effort, it allows you to check the roots' health, avoid pests or diseases, and improve overall air circulation, which is essential for your plants' growth.
