I took some cuttings from my basil plant to make a new plant but they flowered when I had them in water to grew roots. The new plants leaves have grown and looks and smell great but it's not growing tall. Will it eventually grow taller and is there anything I can do to help? Thanks.
From my experience (as well as a number of resources I found like this one), whenever a basil plant starts flowering, it stops growing (in fact, it is recommended that you pinch off any buds if you want it to keep growing.
Not sure if there's anything you can do to make it grow taller at this point unfortunately.
Your new baby vegatatively grown basil plants have no memory of early bolting. Not to worry. The best way to inhibit reproductive growth is by only using a balanced fertilizer where the N is lower in percentage than the phosphorous and potassium. Otherwise, cutting the reproductive growth off will help.
Basil is an annual...above the tropic of Capricorn. Annuals have one job in life; to produce seed. That is why they are so profuse with flowers. But once an annual produces seed its life is done. The best way to deal with this is via proper balanced fertilizer with N lower in percentage than P and K...and cutting those babies off!. The energy is diverted back to the entire plant.
How did you culture your new basil plants? Are they in garden soil? Are they in pots far too large? Did you fertilize? Answers to these questions will help to define the problem. Please send pictures!
