I'm a very novice gardener. In one potato sack I planted about 10 seed potatoes which I have since learnt is far too many. Is my potato harvest doomed? Can I remove some of the plants?
I did that with beets and carrots a few years back. What happens is the vegetables start competing for space underground and end up either being smaller in size or malformed. I would suggest gently taking out 7-8 of these and transplanting them. Of course, it would all depend on where they are in their maturity cycle
