Turnip 'Purple Top White Globe' problems — and how to fix them
Turnip 'Purple Top White Globe' (Brassica rapa var. rapa 'Purple Top White Globe') 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.
Clubroot
Brassica root disease causing swollen, distorted roots and wilting; lime soil to raise pH, improve drainage and rotate brassicas on a 3-4 year cycle.
Flea beetle
Tiny pits shotgun the young leaves and check growth; protect seedlings with fine mesh and keep them watered to grow through the damage.
Woody, bitter roots
Caused by heat, drought or over-mature roots; sow in cool seasons, water consistently and harvest while roots are young at golf-ball to tennis-ball size.
Bolting
Very early or stressed sowings run to flower; sow once soil has warmed in spring or wait for the autumn crop to avoid premature flowering.
