Feverfew in Zone 7A — Mid-Atlantic

Feverfew is a fantastic addition to any Mid-Atlantic garden. Its cheerful, daisy-like flowers bring a touch of whimsy, and it's known for its medicinal properties. Plus, it's a magnet for beneficial insects, which is always a win in our gardens with our humid summers.

While we can have variable spring weather and deer pressure here, Feverfew is pretty adaptable. Our long growing season, usually around 208 days, gives you plenty of time to get a good harvest whether you start seeds indoors or direct sow.

Starting Feverfew indoors gives you a jump start, but it's not strictly necessary here in the Mid-Atlantic. If you want to try it, aim to sow seeds late January through mid February, about eight weeks before you plan to transplant.

Use seed trays filled with a good seed-starting mix. Keep them consistently moist by watering from the bottom to avoid disturbing the tiny seeds, and provide warmth and light – a heat mat and grow lights work wonders. Our moderate spring means you don't have to rush the process.

Transplant your Feverfew seedlings outdoors late March through late April. Before you plant them, harden them off by gradually exposing them to outdoor conditions for about a week.

Space the plants 12-15 inches apart in a sunny or partially shaded spot. Keep an eye on the weather forecast; we sometimes get a late frost in April that could nip tender seedlings, so be prepared to cover them if needed.

Direct sowing Feverfew is a simple and reliable method in our region. Sow seeds early April through early August, once the soil has warmed up a bit.

Prepare the soil by loosening it and removing any weeds. Gently press the seeds into the soil surface – they need light to germinate. Space them about 12-15 inches apart, or thin them to that spacing once they've sprouted.

Feverfew is wonderfully low-maintenance when it comes to watering, a definite plus in our humid Mid-Atlantic climate. Once established, it's quite drought-tolerant, so you don't need to fuss over it too much.

During the spring, when rainfall is usually pretty consistent, you might not need to water at all unless we're experiencing a dry spell. In the hotter, more humid summer months, check the soil moisture regularly. Stick your finger about two inches deep; if it feels dry, it's time to water.

Generally, an inch of water per week, including rainfall, is sufficient. Water at the base of the plant to avoid wetting the foliage, which can encourage fungal diseases in our humid conditions. Signs of underwatering include wilting leaves, while yellowing leaves can indicate overwatering.

Mulching around your Feverfew plants with a layer of organic mulch like shredded leaves or straw helps retain moisture and suppress weeds, making your life even easier.

Deadheading is key to keeping your Feverfew plants blooming throughout the season. Simply pinch or snip off the spent flowers as they fade.

This encourages the plant to produce more blooms instead of putting energy into seed production. After the main flowering period, you can cut the plant back to tidy it up.

Keep in mind that Feverfew self-seeds readily, so if you don't want it spreading all over your garden, be diligent about deadheading. As the first frost approaches in late October, you can let the last flowers go to seed if you want to collect seeds for next year.

You can expect your first Feverfew harvest starting mid June through early November, about 70 days after planting. The plants are ready to harvest when the small, daisy-like flowers are in full bloom.

To harvest, simply snip off the flowering tops with a pair of scissors or pruning shears. Regular harvesting encourages the plant to produce more flowers, so keep at it throughout the season.

Even as late October rolls around and we start thinking about frost, Feverfew can still be harvested. You can dry the leaves and flowers for later use or enjoy them fresh.

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

Self-seeds prolifically

• What it looks like: Numerous seedlings popping up everywhere in your garden, even in places you didn't plant them.
• What causes it: Feverfew is a prolific self-seeder, and the seeds can spread easily in our climate with even rainfall.
• How to fix/prevent it: Deadhead regularly to prevent seed formation. If you let some flowers go to seed, be prepared to pull out unwanted seedlings.

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).

Leaf miners

• What it looks like: Squiggly, pale trails or blotches on the leaves.
• What causes it: The larvae of small flies tunnel between the upper and lower surfaces of the leaves.
• How to fix/prevent it: Remove and destroy affected leaves. Cover plants with row covers to prevent the adult flies from laying eggs. Neem oil can also help control leaf miner infestations.

Mid-Atlantic Specific Challenges: The moderate-to-hot heat and humid humidity of our summers can create favorable conditions for pests and diseases, so keep an eye on your Feverfew plants and take action promptly if you notice any problems. Fortunately, Feverfew is pretty resilient.

Feverfew makes a great companion plant for several garden vegetables and flowers.

Tomatoes benefit from Feverfew planted nearby because it repels some common tomato pests. Roses also appreciate Feverfew as a companion, as it can help deter aphids and other rose pests. Many herbs also grow well alongside Feverfew, creating a diverse and healthy garden ecosystem.

Avoid planting Feverfew near plants that are particularly susceptible to aphids, as Feverfew can sometimes attract these pests.
