Sylvia. i presume you are talking about this years crop of swedes. They should still be small with big leaves at this time. They will only butt as we call it in autumn. a bit early yet.
Barry. Swedes are sown in late May or early June. Never any problems with size here but it depends on how you thin them. If you leave them too close they will be small. 6 to 8 inches apart would give decent size roots. Only 2 swede eaters here so 4 to 6 inches apart gives the size we need.
Swedes are part of the Brasica family so be careful not to follow the cabbages with them.
Hope this is of help to you.
