This question really applies to tomatoes and cucumbers, both which appear to often be sold with two plants very close to each other.
Should both be left to mature? I presume that a person ought to transplant, wait a few days and assuming both are still alive and transplanted well to remove one, right?
I just bought a pair of beef steak tonight and it seems they'd crowd each other out if left together. They're pretty healthy size at the moment.
And tomatoes aside, must the same rule be followed for cucumbers? I figure with them vining I can kind of lead them away from each other so although their roots will be close buddies the plants themselves can probably get enough airspace...
