How to Grow and Care
You can grow Chamomile herb in USDA plant hardiness zones 3 to 9. Chamomile grows best in cool conditions and should be planted in part shade, but it will also grow in full sun. The soil should be dry. Once your Chamomile is established, it needs very little care. Like most herbs, it grows best when it is not fussed over. Too much fertilizer will result in lots of weakly flavored foliage and few flowers. Chamomile is drought tolerant and only needs to be watered in times of prolonged drought.
Plant Chamomile in the spring from either seeds or plants. It's easier to establish Chamomile herb in your garden from plants or divisions than from seeds, but growing Chamomile from seed is also relatively easy.
For the most part, Chamomile is not affected by many pests. However, it is often recommended as a companion plant in the vegetable garden as its strong scent often keeps pests away.
