Well most sites/books generally offer the same advice.
Good drainage.
Water daily.
Drying
If you are drying herbs for winter use, I clip them often, dry them, you can hang them to dry or dry them in the (directions online) oven and then store in a container.
Oils
If you want to make oils, the best harvesting time is right before they flower/go to seed.
Freezing
Some like to freeze the fresh dry (free from moisture) leaves whole.
To do this, place the leaves on a cookie sheet lined with parchment paper and place in the freezer.
Once frozen, you can place them in a freezer bag to use later for soups and sauces.
Usually if I have a question about a particular method of use, I will enter the name of the herb and go from there.
