Chamomile in Zone 5B — Mountain West

Chamomile is a fantastic addition to any Mountain West garden. Its delicate, apple-like flavor makes a soothing tea, and the plant itself attracts beneficial insects to your garden. Plus, the satisfaction of harvesting your own homegrown tea under our intense sun is hard to beat.

Our high altitude, short growing season, and alkaline soil present unique challenges. But with a little planning and attention to timing, you can absolutely enjoy a bountiful chamomile harvest within our 149-day window.

Starting chamomile indoors in early to late March gives you a head start, but it's not strictly necessary. Because our springs can be so late, indoor starting makes sense if you want blooms as early as possible. Otherwise, direct sowing works just fine.

If you choose to start indoors, sow seeds in seed trays filled with well-draining potting mix. Keep them warm and provide plenty of light, either with a grow light or a sunny windowsill. Bottom watering helps prevent damping off – just set the tray in a shallow dish of water until the surface of the soil is moist.

Transplanting chamomile seedlings outdoors should happen late April through mid May, after the risk of hard frost has passed. Before transplanting, harden off your seedlings by gradually exposing them to outdoor conditions for about a week. This prevents transplant shock from our intense UV.

Plant seedlings 6-8 inches apart in well-drained soil. Keep an eye on the weather forecast – even in late spring, we can get unexpected cold snaps. Be ready to cover your young plants if temperatures dip too low.

Direct sowing chamomile is a simple and effective method in our region. Sow seeds late April through mid July, once the soil has warmed up a bit. Chamomile isn't too picky.

Prepare the soil by loosening it and removing any weeds. Scatter the seeds thinly over the surface and gently press them into the soil. Keep the soil consistently moist until the seedlings emerge, then thin them to 6-8 inches apart.

Chamomile is drought-tolerant and thrives in our dry Mountain West climate. Overwatering is a much bigger problem than underwatering. Our low humidity means you don't have to worry as much about foliar diseases.

During the spring, water only when the top two inches of soil feel dry to the touch. You can use the "finger test" for this. Once established, chamomile needs very little supplemental water, typically less than an inch per week. Water deeply at the base of the plant rather than overhead. This reduces water loss to evaporation and keeps the foliage dry.

Signs of underwatering include wilting or drooping leaves. Overwatering leads to leggy, weak growth and can eventually cause root rot. Mulching around your chamomile plants with gravel or straw helps retain moisture and suppress weeds.

You can expect your first chamomile harvest from mid June through early October. The flowers are ready to harvest when the petals begin to bend slightly backward. This is when they have the highest concentration of essential oils.

Harvest in the morning after the dew has dried for best flavor. Gently pluck the flowers from the stem, being careful not to damage the plant. Regular harvesting encourages continued production. As our first frost approaches in early October, harvest all remaining flowers to dry for tea.

Here are some potential problems you might encounter growing chamomile in the Mountain West:

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 and leaves, often in hidden areas. Stunted growth and yellowing leaves. *What causes it:* Sap-sucking insects that thrive in warm, dry conditions. They can be introduced on new plants or spread by wind. *How to fix/prevent it:* Wipe away mealybugs with a cotton swab dipped in rubbing alcohol. Insecticidal soap or neem oil can also be effective. Ensure good air circulation around plants to prevent infestations.

Thrips *What it looks like:* Tiny, slender insects that cause silvery streaks and distorted growth on leaves and flowers. Black fecal spots may also be present. *What causes it:* Small, winged insects that feed on plant sap. They are attracted to light-colored flowers and can be spread by wind. *How to fix/prevent it:* Strong water spray can dislodge thrips. Insecticidal soap or neem oil can be used for heavier infestations. Remove and destroy infested plant parts.

Mountain West Specific Challenges: Our dry climate and intense sun can stress chamomile plants, making them more susceptible to pests. The alkaline soil can also affect nutrient uptake. Regular monitoring, proper watering, and soil amendments can help keep your plants healthy and resilient.

Chamomile is a great companion plant in the Mountain West garden. It attracts beneficial insects like ladybugs and hoverflies, which prey on aphids and other pests.

Good companions include onions, cabbage, broccoli, cucumbers, and green beans. Onions deter many pests, while brassicas benefit from chamomile's pest-repelling properties. Cucumbers and beans benefit from the increased pollination provided by the beneficial insects attracted to chamomile. Avoid planting near mint, as they compete for resources and chamomile prefers drier conditions than mint can tolerate.
