Houseplant problems

Is my houseplant rootbound?

A plant is meaningfully rootbound when a dense root mass limits water, stability or further growth. One root at a drainage hole may simply be following moisture.

Dense root mass

Roots circle the sides and base and replace much of the potting mix.

Water runs through

A dry shrunken root ball may no longer wet evenly.

Poor stability

A large canopy can easily tip an undersized container.

How to narrow down the cause

What supports this cause

Several matching signs are more reliable than one root visible underneath the pot.

What can look similar

Compacted or severely dry mix can also channel water down the sides even when the pot is large enough.

Problem

What to do step by step

  1. 1

    Remove the plant without tearing the root ball and inspect it.

  2. 2

    Choose a container only slightly larger and with drainage.

  3. 3

    Watch moisture after repotting because fresh mix may dry at a different rate.

Observation

What to watch next

  • Roots have room without a large volume of wet unused mix.
  • Water moistens the root ball evenly and drains.
  • The plant stands securely.
Important

A large jump in pot size creates more mix that stays wet and can be more harmful than a snug root ball.
