Chamomile in Zone 6A — Pacific Northwest

Chamomile is a fantastic addition to any Pacific Northwest garden. Its delicate, apple-like flavor makes for a soothing tea, and it's incredibly versatile in the kitchen. Plus, there's real satisfaction in harvesting your own herbs, especially when the cool nights enhance their flavor.

While our mild summers are perfect for many crops, we do have a shorter growing season of around 148 days and the occasional cool, wet spring that can slow things down. But with careful timing, you can easily enjoy a bountiful chamomile harvest from late June through mid-October.

Starting chamomile indoors is an option, especially if you want a head start. Begin in early to late March, about six weeks before you plan to transplant. Use seed trays filled with a good seed-starting mix, and provide warmth and bright light – a heat mat and grow lights can be very helpful on those overcast spring days.

Keep the soil consistently moist, but not soggy. I've found bottom watering works best; just set the tray in a shallow dish of water and let the soil absorb what it needs. This prevents damping-off and encourages strong root growth. Honestly, though, chamomile direct sows so easily, starting indoors is usually only worth it if you're really eager to get a jump on the season.

Transplant your chamomile seedlings outdoors in late April through late May, once the danger of hard frost has passed. Before planting, harden them off by gradually exposing them to outdoor conditions for about a week. Start with an hour or two of shade, then slowly increase the time and sun exposure each day.

Plant them 6-8 inches apart in well-drained soil. Keep an eye on the weather – those late spring showers can be a bit much for young transplants, so provide temporary shelter if heavy rain is expected.

Direct sowing chamomile is simple and often quite successful in the Pacific Northwest. Sow seeds from late April through late July. Choose a spot with well-drained soil and full sun to partial shade. Chamomile isn't picky, but loosening the soil and removing any large clumps will give the tiny seeds a better chance.

Sprinkle the seeds lightly over the soil surface and gently press them in – they need light to germinate. Keep the soil consistently moist until the seedlings emerge, which usually takes about a week or two. Once they're a few inches tall, thin them to 6-8 inches apart. Direct sowing is less work, but you'll need to be diligent about keeping the soil moist until the seedlings are established.

Chamomile is quite drought-tolerant and thrives on neglect, which is perfect for our dry summer months in the Pacific Northwest. The key is to avoid overwatering, which can lead to leggy, weak growth.

During our wet springs, you likely won't need to water at all unless you're experiencing an unusually dry spell. Once the dry summer months arrive, check the soil moisture regularly. Stick your finger about two inches deep into the soil – if it feels dry, it's time to water. Aim for about an inch of water per week, watering deeply at the base of the plants rather than overhead to avoid fungal issues in our humid springs.

Signs of underwatering include wilting or yellowing leaves. Overwatering can cause the leaves to turn pale and the stems to become soft and mushy. A light layer of mulch, like straw or wood chips, can help retain moisture during the dry summer and suppress weeds.

You can expect your first chamomile harvest in late June through mid-October, about 60 days after planting. The best time to harvest the flowers is in the morning, after the dew has dried but before the sun gets too hot. Look for flowers where the petals are just beginning to bend slightly backward.

To harvest, simply snip off the flower heads with scissors or your fingers, being careful not to damage the rest of the plant. Regular harvesting encourages continuous production throughout the season. As the first frost approaches in early October, harvest any remaining flowers, even if they're not fully open, as they'll still have plenty of flavor. Dry them on a screen or in a dehydrator for tea.

Here are a few common problems you might encounter with chamomile in the Pacific Northwest:

Aphids *What it looks like:* Clusters of tiny green, black, or white insects on stems and leaf undersides. You might also notice a sticky honeydew residue or curled, distorted new growth. *What causes it:* Rapid-reproducing, sap-sucking insects thrive in warm weather. Ant colonies may farm them for honeydew. *How to fix/prevent it:* A strong spray of water can knock them off. Encourage ladybugs and lacewings, which are natural predators. For heavy infestations, use insecticidal soap or neem oil. Avoid excess nitrogen fertilizer, which attracts them.

Mealybugs *What it looks like:* Small, white, cottony masses on stems, leaves, and where the leaves join the stem. The plant may be stunted or yellowing. *What causes it:* These sap-sucking insects are more common in sheltered locations. They can spread quickly, especially in warm, dry conditions. *How to fix/prevent it:* Wipe them off with a cotton swab dipped in rubbing alcohol. Insecticidal soap or neem oil can also be effective. Improve air circulation and avoid over-fertilizing.

Thrips *What it looks like:* Tiny, slender insects that are difficult to see with the naked eye. You might notice silvery streaks or distorted growth on leaves and flowers. *What causes it:* These sap-sucking insects are attracted to light-colored flowers and can thrive in warm, dry weather. *How to fix/prevent it:* A strong spray of water can help control them. Insecticidal soap or neem oil can also be effective. Remove any infested plant debris.

Pacific Northwest Specific Challenges: Our mild, dry summers are generally favorable for chamomile, but keep an eye out for aphids, mealybugs, and thrips, especially during warmer stretches. Late blight is less of a concern for chamomile than for tomatoes or potatoes, but good air circulation and avoiding overhead watering can still help prevent fungal issues, especially during our wet springs.

Chamomile is a great companion plant in the Pacific Northwest garden! It attracts beneficial insects and can even improve the flavor of certain vegetables.

Good companions include onions, cabbage, and broccoli. Chamomile is thought to deter cabbage moths, which can be a major pest on these crops. It also works well with cucumbers and green beans. Chamomile is believed to improve their growth and flavor.

Avoid planting chamomile near mint or basil. These herbs can be quite aggressive and may compete with chamomile for resources, especially in our shorter growing season.
