Can You Cut Roots Off a Plant?

As a plant grows, its roots spread out in search of moisture and nutrients in the soil. However, sometimes the roots can become overgrown and start to cause problems for the plant. If you're wondering whether you can cut roots off a plant, keep reading to find out.

Why You May Need to Cut Roots of a Plant

There are several reasons why you may need to cut roots off a plant. Here are a few examples:

Root-bound plants: When a plant has outgrown its pot, the roots can become tangled and start to wrap around the rootball. This can result in stunted growth and poor overall health.

Invasive roots: Some plants have invasive roots that can damage foundations or infrastructure like pipes and sidewalks. In these cases, cutting off the roots may be necessary to prevent damage.

Disease or pests: Root rot and other diseases can affect a plant's roots, causing them to turn brown or mushy. Pests like grubs and root weevils can also damage the roots, making it difficult for the plant to survive.

How to Cut Roots Off a Plant

Before you start cutting roots, it's important to note that removing too many can harm the plant. Always try to avoid cutting more than one-third of the root system. Here's how to safely cut roots off a plant:

Prepare the plant: Water the plant thoroughly the day before you plan to cut the roots. This will help the plant recover more quickly.

Choose the right tool: Use a sharp, clean pair of pruning shears or garden scissors to cut through the roots.

Remove the excess: Carefully remove any soil from the top of the rootball to reveal the roots. Use the shears to cut through any circling or tangled roots, removing only what is necessary.

Re-pot the plant: Once you've finished cutting the roots, carefully replace the plant in its container with fresh, well-draining soil. Water the plant well and place it in a brightly lit area.

When to Cut Roots Off a Plant

The best time to cut roots off a plant is during the dormant season. For most plants, this is in the late fall or early winter. Cutting roots during the growing season can shock the plant and make it difficult to recover. Always avoid cutting roots when the plant is in active growth.

Knowing how to cut roots off a plant can help you keep your garden healthy and vibrant. With these tips in mind, you can safely remove excess roots and give your plants the best possible chance to thrive.
