Troubleshooting
Parsnip 'Tender and True' problems — and how to fix them
Parsnip 'Tender and True' (Pastinaca sativa 'Tender and True') 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.
Erratic germination
Parsnip seed is slow and short-lived. Use fresh seed each year, sow into warm soil from mid-spring, and keep the surface moist until seedlings emerge.
Forked or fanged roots
Stones, compaction, and fresh manure split the taproot. Deeply dig and de-stone the bed and never sow into recently manured ground.
Parsnip canker
Brown-black rot at the shoulder, worse in wet, acidic soil. 'Tender and True' has good resistance; also lime acid soil and avoid root damage.
Carrot/celery fly
Larvae tunnel roots, leaving rusty galleries. Use insect mesh or a low barrier and avoid thinning on still, warm evenings when flies are active.
