How far apart does dill need to be from carrot ?

[Forage420]

I realise that dill and carrot should not be grown too close to each other because of cross-pollination issues but how close is too close?

Cross-pollination can only occur if both plants are in flower at the same time. Since carrots are biennial and would be eaten before they flower (unless you want them for seed) cross pollination is not an issue.
