Daylily 'Autumn Minaret' problems — and how to fix them

Daylily 'Autumn Minaret' (Hemerocallis 'Autumn Minaret') 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.

Wind damage to scapes

The exceptional height makes scapes prone to lodging in exposed sites. Plant in a sheltered spot or stake loosely with bamboo canes before peak height.

Daylily rust

Orange pustules on leaves indicate Puccinia hemerocallidis. Remove and destroy affected leaves; apply appropriate fungicide if widespread.

Spider mites

In hot, dry conditions stippling of lower leaves may appear. Increase irrigation, improve air circulation, and apply miticide if populations are high.

Slug and snail damage

Emerging spring foliage is attractive to slugs. Apply iron phosphate pellets around the crown, or use beer traps.

Leaf streak

Yellow-brown streaking caused by fungal infection. Remove affected foliage, especially at season end, and dispose of rather than composting.
