A lot depends on the rabbits concerned, some are naturally more hormonal than others prior to neutering.
I assume that both male and female are neutered. If the female is not neutereted you need to leave at least 5 weeks before bonding, however you really need to be aware that a female can suddenly become more hormonal and turn which can result in fighting. This is why it is recommended to have the female neutered prior to bonding.
If your female is neutered and depending on the level of hormones in your rabbits you may be able to start bonding, however you need to be very observant and read their behaviour. If either are quite hormonal you may need to abandon and leave it a few more weeks.
