Yeah, you are apt to lose half of those, if the stems turn woody harvest. You have problems with Downy mildew? My sweet basils have fits with it. Is why I grow the African varieties of several herbs- my heat and dryness are terrible this year.
Let me see, yellowing leaves can be both over and under watering. Brown leaves can be pinched dry roots, or too much nitrogen. Many herbs are weeds that thrive on neglect. Pampering them makes them weak, or grow too fast to build strength. Then again, it could simply be Fall die off. Late July and August are considered plant killing months- which means Sept harvests- Cilantro and Arugula will grow fast, harvest fast, replant. I began my Fall planting the end of August for the cooler weather herbs.
