Bell Pepper*they hate nitrogen/commercial fertilizer* Wait til plants flower before fertilizing. Then spray leaves w/ 1 tsp Epsom salt in 1 qt water (peppers need Magnesium to set fruit). Peppers also enjoy small amounts of potassium (wood ashes)
Nice option too container/raised bed herb gardening. Some of these herbs won't stay small and cute, so would need to plan to plant the taller ones in the upper tiers and maybe with a little bit larger growth area.
