Signs of Overwatering

Yellow, wilting fronds combined with a soft, mushy base at the trunk mean the roots are rotting from consistently soggy soil.

Signs of Underwatering

The stiff, feather-like fronds turn brown starting from the tips inward, though this plant tolerates drought far better than overwatering.

Adjusting for the Seasons

Not a true palm but a cycad, one of the oldest plant lineages on Earth - growth is extremely slow, often producing just one new flush of fronds per year, so patience matters more than frequent feeding.

Pro Tip

Every part of this plant is seriously toxic to pets, with the seeds being the most dangerous - if you have curious cats or dogs, this is one of the few common houseplants worth reconsidering or keeping strictly out of reach.
