Troubleshooting
Canada Mayflower problems — and how to fix them
Canada Mayflower (Maianthemum canadense) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Yellowing leaves
Usually indicates soil pH is too alkaline or soil has been allowed to dry out. Test pH and amend with sulfur or ericaceous compost to lower it. Water more frequently during dry spells and mulch to retain moisture.
Slow establishment
Canada Mayflower is slow to establish from divisions or transplants, especially if soil conditions are not sufficiently acidic and moist. Patience is required; ensure the correct soil pH and avoid disturbing new plantings in the first two seasons.
Slug damage
Young spring growth is susceptible to slug feeding, leading to torn or notched leaves. Apply iron phosphate slug bait or diatomaceous earth around plants in early spring when shoots emerge. The low height makes damage particularly visible.
