Just meet their basic needs, and they'll reward you with bountiful harvests. Choose the right site. Most herbs need lots of sun and well- drained, fertile soil. Have your soil tested. If you have any doubts as to your soil's fertility, have it tested and then make adjustments to balance fertility levels.
Most herbs do well with a little higher pH than our natural soil contains.
It's a myth that herbs don't need nutrients. What you put in is what you get out. Also, compost makes an excellent addition to the herb bed each year. Work it into the top six to eight inches of the soil profile. Start with plants, not seeds.
