Well, you should never have to maintain locks. The point of them is that you don't have to keep working on them, no matter how infrequently. Crocheting does so much damage to your hair that it will take months or years to recover from even 1 or 2 sessions. All a crochet needle does is break hairs and make them look worse in the long run.
It is true that it can take around 6 months for them to mature and look like the locks you are imagining they will look like. If you feel like you have to have them look more "groomed", you can put beads on them to keep them separated from each other. But just so you know, locks are messy matted hair. It takes time for them and patience for them to become mature.
All you should be doing is washing them often and keep separating them so they don't congo together. That's all.
You could wear a tam or abandanna to keep them back and out of your face, but remember that if you wear a tam, you'll have to separate more often, and if you tie them back, you will be hindering the process. It's best to do nothing and just let them hang free. If you wash enough, they will grow faster and be healthy
