Troubleshooting
Pacific Purple Asparagus problems — and how to fix them
Pacific Purple Asparagus (Asparagus officinalis 'Pacific Purple') 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.
Asparagus beetle
Beetles and larvae chew the spears and ferns, sapping crown strength. Hand-pick them, remove old fern debris in autumn, and tackle infestations early.
Crown rot
Heavy, wet soil rots the crowns. Plant in free-draining or raised soil and avoid any site that waterlogs over winter.
Colour loss when cooked
The purple pigment is heat-sensitive and turns green when cooked, surprising some growers. Serve raw or very lightly cooked to keep the colour and sweetness.
Premature harvesting
Cutting in the first two years drains the developing crowns and reduces lifetime yield. Wait until year three to harvest fully.
