Chamomile in Zone 6B — Mid-Atlantic

Chamomile is a worthwhile addition to any Mid-Atlantic garden. Its delicate, apple-like flavor makes a soothing tea, and its cheerful flowers attract beneficial insects. Plus, a sprawling patch of chamomile releases a lovely fragrance when you brush against it on a warm, humid summer evening.

Our four seasons and sometimes variable springs present a few challenges, but Chamomile is quite adaptable. With a 198-day growing season, you'll have plenty of time to enjoy this herb. Proper timing and attention to watering are key.

Starting chamomile indoors gives you a head start, but it's honestly not always necessary in our Mid-Atlantic climate. Direct sowing works just fine! However, if you're eager to get an early harvest or want to control the environment better, indoor starting is an option.

Start your seeds indoors in early to late February, about six weeks before you plan to transplant. Use seed trays with a good seed-starting mix and provide warmth (a heat mat is helpful) and plenty of light (grow lights are ideal). Don’t bury the seeds too deep; they need light to germinate.

A great tip is to water from the bottom to prevent damping off. Just set the tray in a shallow container of water and let the soil absorb the moisture. This helps keep the soil evenly moist without overwatering, which is especially important during our moderate Mid-Atlantic springs.

Transplant your chamomile seedlings outdoors in late March through late April, after the danger of hard frost has passed. Keep an eye on the forecast; we can sometimes get a late cold snap here in the Mid-Atlantic!

Before transplanting, harden off your seedlings by gradually exposing them to outdoor conditions for about a week. Start with an hour or two of shade and increase the time and sun exposure each day. This helps them adjust to the elements and reduces transplant shock. Space your chamomile plants 6-8 inches apart in a sunny spot with well-drained soil.

Direct sowing chamomile is a straightforward method that works well in the Mid-Atlantic. You can sow seeds directly into the garden from late March through mid August. This gives you a wide window to work with, taking advantage of our reliable rainfall.

Prepare the soil by loosening it and removing any weeds. Chamomile prefers a slightly sandy soil, so amend with compost if you have heavy clay. Scatter the seeds thinly over the soil surface and gently press them in. They need light to germinate, so don't bury them too deeply.

Keep the soil consistently moist until the seedlings emerge, which usually takes about two weeks. Thin the seedlings to 6-8 inches apart once they are large enough to handle. Direct sowing is less work but may result in a slightly later harvest compared to starting indoors.

Chamomile is relatively drought-tolerant once established, but proper watering is still essential, especially during our humid summers. The key is to find the right balance—avoiding both drought and overwatering.

In the spring, when rainfall is generally consistent, water only when the top two inches of soil feel dry to the touch. Use the "finger test" to check this. During our moderate-to-hot summer months, you might need to water once or twice a week, providing about an inch of water each time, especially if we're experiencing a dry spell.

Water at the base of the plants to avoid wetting the foliage, which can encourage fungal diseases in our humid climate. Overhead watering is fine in the morning, giving the leaves time to dry out before nightfall. Mulching around your plants with straw or wood chips helps retain moisture and suppress weeds, which is beneficial during the warmer months.

Yellowing leaves and wilting are signs of underwatering, while leggy growth and root rot indicate overwatering. Adjust your watering schedule accordingly. Chamomile thrives in well-drained soil, so avoid planting in areas that tend to stay soggy.

You can expect your first chamomile harvest in late May through early November, about 60 days after planting. The flowers are ready to harvest when the petals bend slightly backward from the yellow center.

Harvest in the morning after the dew has dried for the best flavor and aroma. Use scissors or your fingers to gently pluck the flower heads from the plant, being careful not to damage the stems. Regular harvesting encourages continued production throughout the growing season.

To dry the flowers for tea, spread them out in a single layer on a screen or clean cloth in a cool, dark, and well-ventilated place. Once they are completely dry (they should crumble easily), store them in an airtight container. As the first frost approaches in late October, harvest any remaining flowers to preserve them before the cold weather sets in.

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: White, cottony masses on stems, leaves, and in leaf joints. Stunted growth. Sticky honeydew residue.
• What causes it: Sap-sucking insects that thrive in warm, humid conditions. Often introduced by ants.
• How to fix/prevent it: Wipe away with a cotton swab dipped in rubbing alcohol. Strong water spray can dislodge them. Introduce beneficial insects like ladybugs and lacewings. Insecticidal soap or neem oil for heavy infestations. Control ant populations.

Thrips

• What it looks like: Tiny, slender insects (yellow, brown, or black) on flowers and leaves. Silvery or distorted foliage. Black specks of excrement.
• What causes it: Sap-sucking insects that feed on plant tissues. Thrive in hot, dry weather, but can also be a problem in our humid summers.
• How to fix/prevent it: Strong water spray. Insecticidal soap or neem oil. Blue sticky traps can attract and capture them. Encourage beneficial insects like lacewings and predatory mites.

Mid-Atlantic Specific Challenges: Our moderate-to-hot summers and humid conditions can create an ideal environment for aphids, mealybugs, and thrips. Consistent monitoring and prompt action are crucial to prevent infestations from getting out of control. Pay extra attention during periods of high humidity and heat, and ensure good air circulation around your plants to reduce the risk of problems.

Chamomile plays well with several common Mid-Atlantic garden vegetables. Planting chamomile near onions is beneficial because it is thought to improve their flavor and growth. Similarly, chamomile can help protect cabbage and broccoli from certain pests, thanks to its insect-repelling properties.

Chamomile also makes a good companion for cucumbers, as it attracts beneficial insects that can help with pollination. Green beans benefit from chamomile because it deters bean beetles. Avoid planting chamomile near mint, as they compete for resources and chamomile prefers drier conditions, while mint thrives in moist soil.
