Chamomile in Zone 7B — Mid-Atlantic

Chamomile is a fantastic addition to any Mid-Atlantic garden. Its delicate, apple-like flavor makes for a soothing tea, and its cheerful flowers attract beneficial insects. Plus, the satisfaction of growing your own herbs in our four distinct seasons is hard to beat.

While our humid summers and occasional deer pressure can present challenges, Chamomile is surprisingly resilient. With a growing season that stretches over 200 days, you'll have plenty of time to enjoy this delightful herb.

Starting Chamomile indoors in the Mid-Atlantic isn't strictly necessary, but it can give you a head start. If you're eager for an early harvest, sow seeds indoors from late January through mid February, about six weeks before the last expected frost.

Use seed trays with a good seed-starting mix. Keep them warm and provide plenty of light, either from a sunny windowsill or a grow light. Bottom watering helps prevent damping-off, a common issue with seedlings, especially with our moderate spring.

Once the danger of hard frost has passed, usually from mid March through mid April, you can transplant your Chamomile seedlings outdoors. Before planting, harden them off by gradually exposing them to outdoor conditions for about a week.

Space the plants 6-8 inches apart in a sunny spot with well-drained soil. Keep an eye on the weather forecast; we sometimes get unexpected cold snaps this time of year, so be ready to cover your seedlings if needed.

Direct sowing Chamomile is a simple and effective method in the Mid-Atlantic. From mid March through mid August, you can sow seeds directly into your garden bed.

Choose a location with full sun to partial shade and prepare the soil by loosening it and removing any weeds. Chamomile prefers slightly acidic soil, so consider amending with compost. Keep the soil consistently moist until the seedlings emerge, spacing plants 6-8 inches.

Chamomile is relatively drought-tolerant, making it a good choice for our region's even rainfall. However, consistent watering is still important, especially during establishment.

During the warmer months, give your Chamomile a good soaking if we haven't had rain for a week. Stick your finger about two inches into the soil – if it feels dry, it's time to water. Aim for about an inch of water per week, either from rainfall or irrigation. Water at the base of the plant to avoid wetting the foliage, which can encourage fungal diseases in our humid climate.

Overwatering is a bigger concern than underwatering. Yellowing leaves and leggy growth are signs of too much moisture. On the other hand, wilting leaves indicate the need for water. A light layer of mulch, like shredded bark, can help retain moisture without waterlogging the soil.

You can expect your first Chamomile harvest from mid May through early November in the Mid-Atlantic. The best time to harvest is in the morning after the dew has dried, when the flowers are at their peak.

Look for flowers where the petals are just beginning to bend slightly backward. Gently snip off the flower heads, being careful not to damage the rest of the plant. Regular harvesting encourages continued production throughout the growing season.

As the first frost approaches in early November, you can harvest any remaining flowers. Dry them indoors on a screen or in a dehydrator for use in teas and other herbal remedies.

Here are some common problems you might encounter with Chamomile in the Mid-Atlantic:

Aphids

• What it looks like: Clusters of tiny soft-bodied insects (green, black, or white) on stems and leaf undersides. Sticky honeydew residue. Curled or distorted new growth.
• What causes it: Rapid-reproducing sap-sucking insects. Populations explode in warm weather. Ant colonies may farm them for honeydew.
• How to fix/prevent it: Strong water spray knocks them off. Encourage ladybugs and lacewings (natural predators). Insecticidal soap for heavy infestations. Neem oil works systemically. Avoid excess nitrogen fertilizer (it attracts them).

Mealybugs

• What it looks like: Small, white, cottony masses on stems and leaves, often in hidden areas. Stunted growth and yellowing leaves. Sticky honeydew residue.
• What causes it: Sap-sucking insects that thrive in warm, humid conditions. They are often brought in on new plants or spread by ants.
• How to fix/prevent it: Wipe away with a cotton swab dipped in alcohol. Insecticidal soap or neem oil can also be effective. Improve air circulation around plants to reduce humidity.

Thrips

• What it looks like: Tiny, slender insects that are difficult to see with the naked eye. Silvery streaks or stippling on leaves and flowers. Distorted or damaged buds.
• What causes it: Sap-sucking insects that feed on plant tissues. They are attracted to light-colored flowers and can spread rapidly in warm, dry weather.
• How to fix/prevent it: Strong water spray can dislodge them. Insecticidal soap or neem oil can be used for heavy infestations. Blue sticky traps can help monitor and control populations.

Mid-Atlantic Specific Challenges: Our moderate-to-hot heat and humid summers create ideal conditions for aphids, mealybugs, and thrips. Regular monitoring and good air circulation are key to preventing infestations. Clay soil can also lead to root rot if drainage is poor, so amend your soil with compost and organic matter.

Chamomile is a beneficial companion plant in the Mid-Atlantic garden. It's said to improve the flavor of onions, cabbage, and broccoli when planted nearby. It also attracts beneficial insects like ladybugs and lacewings, which prey on aphids and other pests that can plague our gardens during the humid summers.

Planting Chamomile near cucumbers and green beans can also be helpful, as it can deter certain pests that target these crops. Avoid planting near mint, as it can be invasive and compete with Chamomile for resources.
