Pick the location for your herb garden. An ideal location would be a few steps from your kitchen, but any spot that gets about six hours of sun a day is good. If you have space in front of a kitchen window, plant the herbs in small containers for an indoor garden.
Not enough humidity
Our homes tend to be dry, thanks to air conditioning and heating systems that remove moisture from the air. This is mostly an issue in winter, especially if you have plants anywhere near a heating vent. The easiest solution is to place herb pots on top of a tray covered in large gravel or pebbles filled with water to just below the tops of the pebbles. The evaporation from this tray will provide plants with the 50% level of humidity houseplants prefer. You can also place a humidifier in the same room as your plants to keep the air moist.
Prepare the Area for Planting
Prepare the area for planting by loosening the soil. If the soil is compacted or consists of heavy clay, improve drainage by adding some compost, peat moss or coarse sand. Work the material into the top foot of soil before you plant. Tip: Plant early in the morning or late in the afternoon to prevent the transplants from wilting in the midday sun.
Dig Planting Holes
Because you are starting herbs from bedding plants and not seeds, you will need to create larger planting holes. Dig each hole to about twice the width of the root ball of the new plant.
Add Plants to Soil
Space the bedding plants about 18 inches apart to give them room to spread out and grow. Tip: Place taller herbs, like sage, rosemary and marjoram, toward the back of the garden, and place parsley and cilantro at the front.
Add labels to each of your freshly planted herbs to make them easy to identify when cooking.
Surround With Flowering Plants
For accents of color in your herb garden, add flowering plants like zinnias and salvia. Tip: Plant perennials on one side and annuals on the other for easier replanting next year.
Give the new transplants plenty of water. Once established, make sure your herbs get an inch of water each week throughout the growing season.
Harvest Mature Herbs
Begin harvesting from the herbs as soon as they are mature, but take only a little bit each time you harvest. If you remove more than a third of the plant at one time, it takes longer to recover and produce new foliage. To promote branching, keep the tops of the plants pinched back in early summer. With judicious picking, most herbs can be harvested for several months. Tip: Fresh herbs taste best when harvested in the morning. Also, herbs are most flavorful if harvested before they bloom.
