Summarize this article in one sentence.
Herbs are tender plants that won't do well if sown in cold temperatures. Therefore, you should plant herbs outdoors in the spring once the temperatures, and the soil, have begun to warm up. To find the average frost dates for your area, check your local weather app. If you purchased herb plants, rather than seeds, you'll need to dig holes for each plant. Make sure the holes have the same depth as the container and are twice as wide. Use your hands to carefully remove the plant from the container and gently break up the roots. Place the plant in the soil, with only the root ball below the surface, and lightly pack the soil around the plant. Use your finger or the eraser end of a pencil to make shallow indentations in the soil. Place 1 seed in each space, then lightly cover it with soil. Take care not to bury the seeds too deep, or they won't germinate. Once your seeds or plants are in the garden or containers, lightly water them to compact the soil. If you transplanted the herbs, be sure to water down to the root zone to help the plant become established in the soil. Since many herbs look similar, it's a good idea to place labels in the garden or containers. You can put the seed packet in a plastic bag and staple it to a wooden stake, which can then be placed in front of the herbs. You could also use the plant label that came with the plants and stick it into the soil near the herbs. Or, you could even make your own labels, such as by painting the herb names on rocks and placing them near each herb. No matter which type of label you choose, make sure it is waterproof!
Wait to plant until the risk of frost has passed. Place existing plants in holes that are twice as wide as their container. Sow seeds 18 inch (0.32cm) deep. Water the herbs immediately after planting. Label each herb.
