Houseplant problems

Springtails in houseplant soil

Springtails usually feed on fungi and decaying material in damp potting mix. Large numbers more often point to persistently wet conditions than to direct damage on a healthy plant.

What they look like

They are extremely small and spring away when the surface is disturbed.

What they favor

Constant moisture, organic debris and fungal growth near the surface.

What to inspect

Drainage, watering frequency and any unpleasant smell from the mix.

More useful detail

How to narrow down the cause

Assess the plant

Healthy roots and fresh growth suggest that the main issue is the potting environment.

Avoid extreme drying

Reducing moisture must still match the species instead of creating a prolonged drought.

Problem

What to do step by step

  1. 1

    Delay the next watering until the plant actually needs it.

  2. 2

    Clear the drainage holes and empty water held in the outer pot.

  3. 3

    If the mix stays wet or smells sour, inspect the roots and consider repotting.

Observation

What to watch next

  • The potting mix dries at a more predictable rate.
  • Springtail numbers fall without the plant declining.
  • Roots remain firm and pale rather than soft or foul-smelling.
Important

Springtails alone do not prove root disease. Let the condition of the roots, mix and plant determine whether repotting is necessary.
