Should I cut off the yellow leaves?

Canadian lousewort: yellow leaves, causes and fixes

Check these first

Check the soil moisture by sticking your finger 2 inches deep.
Inspect the drainage holes to ensure they are not blocked.
Look for signs of standing water in the saucer.

Likely causes

Overwatering
Most likely
How to tell: The leaves turn yellow starting from the bottom of the plant and feel soft or mushy. The soil often stays damp for more than 7 days.
What to do: Allow the top 1 to 2 inches of soil to dry out before watering again. Ensure your pot has drainage holes so excess water can escape freely.
Nutrient Deficiency
Possible
How to tell: The leaves turn a pale yellow while the veins remain green. This often happens if the plant has been in the same soil for over a year.
What to do: Apply a balanced liquid fertilizer diluted to half strength once during the early spring. Do not overfeed, as this plant prefers moderate soil fertility.
