Repotting FAQs: Choosing the Right Pot Size for Your Plants

How Big Should the Pot Be When Repotting?

When repotting, the general rule is to select a pot that is 2.5-5 cm (1-2 inches) larger in diameter than the current pot for smaller plants or 5-10 cm (2-4 inches) larger for larger plants. This gradual increase ensures that the plant’s roots have room to grow without being overwhelmed by excess soil, which can retain water and lead to root rot. Knowing how to choose the right pot size for repotting plants can make a big difference.

For example:

• A plant in a 10 cm (4-inch) pot would do well in a 12-14 cm (5-6 inch) pot after repotting.
• Larger plants, such as a Monstera in a 20 cm (8-inch) pot, can move up to a 24 cm (10-inch) pot.

Avoid jumping to a pot that is too large, as the excess soil can remain waterlogged, creating a poor environment for roots. When deciding on how to choose the right pot size for repotting plants, avoid opting for pots that are too large.

What If the Roots Are Small? Should I Only Change the Soil and Keep the Same Pot Size?

If your plant’s roots haven’t filled the current pot, or if they seem small or underdeveloped, you may not need to move to a larger pot. Instead, you can refresh the soil while keeping the same pot. Fresh soil provides new nutrients and improves drainage, both of which can encourage healthy root growth.

Make sure to:

• Remove any old, compacted soil gently.
• Trim off any dead or damaged roots.
• Repot with fresh, high-quality potting mix. For plants like Monstera or Philodendron, consider using an aroid mix, which is available on our website.

For Monstera, Philodendron, Syngonium, and other aroid plants, adding a moss pole during repotting is always a good idea. Moss poles help these plants mimic their natural growth habits, encourage bigger leaves, and provide support for climbing. They also help in how to choose the right pot size for repotting plants more effectively.

When Should You Choose a Smaller Pot When Repotting?

Although rare, there are situations where downsizing to a smaller pot is beneficial. This is typically necessary if:

• The plant’s root system has significantly reduced, such as after root rot treatment or pest issues.
• The plant has been over-potted and struggles to absorb water effectively due to excess soil.

When downsizing:

• Choose a pot just large enough to comfortably fit the healthy roots.
• Ensure the new pot has adequate drainage.
• Use fresh soil to replenish nutrients.

Additional Tips for Repotting Success

• Inspect the Roots: Check for signs of root rot, pests, or overcrowding. Healthy roots are white or light tan and firm.
• Water After Repotting: Water the plant lightly after repotting to help settle the soil. Avoid overwatering, as the roots need time to adjust.
• Provide Stability: Tall or top-heavy plants may need staking after repotting to prevent them from tipping over in their new pot.
