I have a basil plant that grew into a huge bushy thing over the summer...it was great plenty of fresh basil...it flowered and has not come back.....it is just turning brown and dying...what has happened?? my thyme plant did the exact same thing but has continued to grow and get really healthy...the basil...I don't know what has happened...all my other herbs are sweet also...I am just comparing the thyme and basil as they flowered at the same time and actually looked similar...
Should I just get another seedling or will it come back?
Already stretching it into the later-part of the planting season for basil, but it won't be critical. To answer your questions, go buy a few more basil plants of you chooising (too late for seedlings IMO) and get them into your garden ASAP.
Basil is not a perennial plant, they last a year per life cycle. Nothing you do will really get it to live longer than one whole year, treat it well though and if it's a robust plant and it will last for a long time though (through the winter if you have mild winters). In the future, it would actually do you best to trim or nip the flowers it blooms, especialy earlier in life, as this forces it to invest energy it was going to invest into flowering into more foliage and mass growth (which are the parts we harvest for our cooking).
I was just helping my mom plant her basil for this year, tomatoes too and dividing up some thyme we planted last year in her gardens this weekend.
