Both thrive in similar moisture and shade conditions. They also share the benefit of resilience in cool, damp environments, making for a visually complementary planting scheme.
Scale Insects

Scale insects may infest the fronds. They appear as small, crusty bumps and can weaken the plant if not treated. Symptoms include stunted growth and discoloration.

Mealybugs

Mealybugs feed on sap, appearing as small, cottony masses on the fronds. Heavily infested fronds might be distorted, dry out, and die off. Early detection and treatment is important.

Slugs and Snails

Slugs and snails can damage the fronds and tender new growth. Look for holes and ragged edges on leaves. Appropriate preventative measures and removal should be considered.
