Actually, I grow herbs because I like them fresh but there are a few that are better dried like bay leaves and dill.
Bay leaves- dried in the oven over low heat for 4 hours. It can be done in a dehydrator
Lavender- tie flower bundles with rubber band and store in cool dry place ( usually hang from rafters) until dried then it can be used in sachets, and potpouris
Basil, thyme, rosemary, can be made into herb butters. You can add garlic to any herb butter
Lemons, limes - freeze juice in ice cube trays. Use for lemon ade or lemon tea
Dill, can be dried, but I prefer it fresh
vanilla. It is a long process. After the pod is pollinated, wait about 9 months for it to ripen and turn black. After picking pods they have to be brought out every day on a sunny day for about 6 months and taken in if it rains. Dried pods can store in an air tight bottle for a long time, or pods can be placed in sugar.
Basil can be washed dried and stored in a clean air tight bottle layered with rock salt
Cilantro, basil, thyme, marjoram, dill can be pureed and frozen in ice cube trays. O.k. for cooked dishes but they don't have good texture or color for garnishes or Thai dishes.
Green onions actually store better chopped up than whole in the frig for a couple of weeks
Ginger- After harvest peel outer skin by scraping with a large spoon. Cut into 1 inch pieces and place in a clean jar. Cover with Dry Sherry or Shao Xing wine. Make sure pieces are always submerged or mold will grow. Can be kept a 6 mos to a year. Ginger flavored sherry can be used in Asian dishes. Do not reuse sherry. Need to use fresh wine for new batch.
Tumeric and ginger can be stored in a cool shady place in moist sand for about 3 months. Plant it out if it sprouts.
Kaffir lime leaves can be frozen, but it loses texture and flavor over time. If you make the curry paste and freeze that it lasts longer.
Chili peppers- pickle in vinegar, salt, garlic, dry, dry; pulverize to powder and freeze. Peppers get rancid over time so dried peppers, pepper seeds, and pepper powder last longer if they are frozen after processing.
Stevia- make infusion steep one cup of stevia leaves in a cup of hot water. You can use alcohlol,or glycerin to preserve it longer. strain. Keep in refrigerator. Do not make large batches, it does not keep more than a month very well. It can be dried and ground to a powder as well.

garam masala. I would make garam masala using some of the store bought ingredients like cardomom and cinnamon but the dried seeds head of my fennel, coriander, cumin, and dried bay leaves. My pepper vine has not flowered yet, but it is still alive.
