Troubleshooting
Salsify 'Mammoth Sandwich Island' problems — and how to fix them
Salsify 'Mammoth Sandwich Island' (Tragopogon porrifolius 'Mammoth Sandwich Island') 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.
Forked or hairy roots
Stones, compaction or fresh manure split the taproot; dig deeply and use only well-rotted organic matter, sowing direct to avoid transplant damage.
Premature bolting
Very early sowing or a cold check can trigger first-year flowering, turning roots woody; sow once soil has warmed and keep growth steady.
Self-seeding and weediness
Flowers left to set produce dandelion-like seed heads that spread freely; deadhead or harvest before seeding if volunteers are unwanted.
White blister and leaf rusts
Damp, crowded foliage can develop fungal pustules; space plants for airflow and avoid overhead watering late in the day.
