Troubleshooting
Aleutian mountain heather problems — and how to fix them
Aleutian mountain heather (Phyllodoce aleutica) 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.
Difficulty establishing outside maritime or cool climates
P. aleutica is native to one of the coolest, dampest environments on earth. In continental climates with warm summers and dry air, it rarely thrives long-term. Seek out the coolest, most sheltered and moist garden microclimate available, or grow in an alpine house.
Root rot from summer waterlogging
Despite needing consistent moisture, the soil must drain freely. Stagnant water at the roots, particularly in warm summers, causes Phytophthora root rot. Raised beds with a gritty, free-draining mix are the most reliable cultivation approach.
Interveinal chlorosis from high soil pH
Yellowing between leaf veins indicates rising soil pH. Test regularly and correct with elemental sulfur or switch all irrigation to rainwater. Top-dress annually with acidic ericaceous compost to maintain the required pH range.
