To solve this, we recommend regular trimming of your plant. If you are using your herbs regularly, this shouldn’t be a problem. If you aren’t using your herbs that often, we recommend trimming the top of your plant about once a week to keep it bushy and prevent flowering.
Pruning and trimming not only prevents flowering, but it makes your plant bushier and encourages lots of new growth. A good rule of thumb when pruning is to not remove more than ⅓ of the plant at one time. When pruning, make sure to use clean, sharp scissors or garden shears. You can clean your shears using rubbing alcohol, and we suggest cleaning your shears in between trimming each plant.
If the plant has already started flowering, no problem. Simply cut off all of the flowers and it will start regrowing new leaves.
