I've had no luck with onions, but for carrots check that your soil is loose enough. Dense or compacted soil could be the cause of forking. You may want to add some organic material such as compost or peat moss. Also some sand or gypsum. When they start looking crowded, pull some to thin them out. I use the thinned roots for snacks and throw the greens in soup or salad.
