Troubleshooting
Hosta 'August Moon' problems — and how to fix them
Hosta 'August Moon' (Hosta 'August Moon') 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.
Bleaching in excess sun
While sun-tolerant, very intense direct afternoon sun can bleach the gold to washed-out cream with brown scorch patches; provide afternoon shade in hot regions.
Slug damage
Protect emerging spring foliage with slug deterrents before leaves unfurl fully.
Poor colouration in deep shade
Grown in heavy shade the leaves remain chartreuse-green rather than turning gold; site in a position with at least 2-3 hours of indirect morning light.
Crown rot
Avoid planting too deeply; the crown should sit just at or slightly above soil level.
Yellowing in late summer
Some early leaf yellowing from late August is normal seasonal senescence as the plant begins dormancy, not a nutrient deficiency.
