Troubleshooting
Parsnip 'Gladiator' problems — and how to fix them
Parsnip 'Gladiator' (Pastinaca sativa 'Gladiator') 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.
Poor germination
Parsnip seed loses viability fast. Sow fresh seed into soil above 7°C, keep the seedbed moist, and allow up to 3-4 weeks. 'Gladiator' germinates more evenly than open-pollinated types but still needs patience.
Parsnip canker
Orange or black crown rot. 'Gladiator' carries good resistance; reinforce it with free-draining soil, generous spacing, and earthing up to cover exposed shoulders.
Forked roots
Stones, compaction, or fresh manure split the taproot. Grow in deeply dug, stone-free soil enriched for a previous crop rather than at sowing.
Sap-blistered skin
Handling foliage in sunlight can blister bare skin from furanocoumarins; wear gloves and cover arms when thinning or harvesting on bright days.
