Once you've grown your own culinary herb garden and cooked using the herbs in it, you'll want to plant one every year. Culinary herbs are easy to grow and freshly picked ones add a lot of flavor to the dishes you prepare. Herbs are one of the easiest types of plants to grow; essentially you dig up the ground and plant them. They'll thrive with no additional fertilizer and very little artificial watering. If possible, put your herb garden near your kitchen door so you can run out and cut what you need when you're cooking dinner.
Choose the site for your culinary herb garden. It should get at least 6 hours of sun per day, but 8 hours would be better. Keep it away from trees; the leaves will shade them and the roots of the tree will rob moisture and nutrients from your herbs.
Prepare the garden bed. Herbs don't like rich soil; do nothing to prepare the soil in your herb garden except turn it over with a shovel to loosen it. Rake it smooth before planting.
Determine which culinary herbs you want to grow. Choose common herbs like parsley, basil, thyme, rosemary, sage, chives, garlic chives, oregano and dill. These herbs are all commonly used in cooking. Unless you have a very large plot for your herb garden, stay away from little used culinary herbs like borage, angelica or sorrel. Limit your selection of culinary herbs to those you actually use.
Lay out your plan on paper prior to planting. Consult seed catalogs to learn the mature size and height of the herbs you want to grow. Place the taller ones on the north side of the garden so they don't shade the other herbs. Varieties like dill, tarragon and basil can grow quite tall and should be planted in the back row. Medium-sized rosemary, sage and chives can be planted in the middle row and shorter herbs like thyme, oregano, marjoram and cilantro should be planted in the front row on the south side of the herb garden.
Space the herbs approximately 12 to 18 inches apart in all directions within the garden bed. The only exceptions to this are dill and tarragon; these two herbs grow and spread quite a bit and should be spaced at least 24 to 30 inches away from other plants.
Make sure to water them regularly, but only if they need it. As a general rule, garden plants need the equivalent of 1 inch of rainfall per week to grow and thrive. Most herbs will grow and thrive with less rainfall than this, but they will also reward you with a lot of growth if they receive the same amount of water as the rest of your vegetables.
