Everything it needs
9 essentials at a glance
Watering
Agrimony prefers consistently moist soil but is susceptible to root rot if overwatered.
Water the plant when the top inch of soil feels dry, typically every 1-2 weeks. During hotter months, increase frequency as needed. Signs of overwatering include yellowing leaves and a mushy stem, while underwatering may cause wilting and browning leaf edges.
Light
Agrimony thrives in full sun to partial shade, ideally receiving 6-8 hours of direct sunlight daily.
It can tolerate some shade, especially in hotter climates, but too much shade may hinder flowering. Ensure the plant is placed where it can receive morning sun and some afternoon shade if temperatures are high.
Soil
The ideal soil for Agrimony is well-draining, rich in organic matter, with a pH range of 6.0 to 7.0.
A mixture of loamy soil and compost or well-rotted manure is recommended. Ensure good drainage to prevent waterlogging, which can lead to root rot.
Humidity
Agrimony prefers moderate humidity levels, around 40-60%.
To increase humidity, mist the leaves or place a humidifier nearby. Conversely, if humidity is too high, ensure good air circulation. Signs of humidity stress include browning leaf tips and stunted growth.
Temperature
Agrimony thrives in temperatures between 60-75°F (15-24°C) and is hardy in zones 3-8.
It can tolerate cold temperatures but may die back in extreme heat. Protect the plant from frost in colder climates by covering it or bringing it indoors if potted.
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10, applying it every 4-6 weeks during the growing season (spring and summer).
Reduce fertilization in fall and winter. Signs of nutrient deficiency include yellowing leaves and poor growth, indicating a need for more nutrients.
Pruning
Prune Agrimony in early spring to remove any dead or damaged stems and to encourage bushier growth.
Use clean, sharp pruning shears. Deadheading spent flowers throughout the blooming season can promote further flowering and maintain the plant's appearance.
Repotting
Repot Agrimony every 2-3 years or when it becomes root-bound, indicated by roots growing out of the drainage holes.
Choose a pot 1-2 inches larger in diameter. Carefully remove the plant from its pot, loosen the roots, and place it in fresh soil, ensuring the crown is at soil level.
Propagation
Agrimony can be propagated through seeds or division.
For seed propagation, sow seeds in spring after the last frost, covering them lightly with soil. Keep the soil moist until germination. For division, dig up established plants in early spring or fall, ensuring each division has roots and shoots, then replant immediately.
When it's unhappy
Yellow leaves
Why it happens
This can be caused by overwatering or nutrient deficiency.
How to fix it
Check soil moisture and reduce watering frequency. If nutrient deficiency is suspected, apply a balanced fertilizer.
Root rot
Why it happens
Overwatering or poor drainage can lead to root rot.
How to fix it
Ensure the pot has adequate drainage holes and reduce watering frequency. If root rot is present, remove affected roots and repot in fresh soil.
Wilting
Why it happens
Wilting can occur due to underwatering or extreme heat.
How to fix it
Check soil moisture and water the plant if the soil is dry. Provide shade during the hottest part of the day if necessary.
Pest infestations (aphids, spider mites)
Why it happens
Pests can attack the plant, especially in dry conditions.
How to fix it
Inspect the plant regularly and treat infestations with insecticidal soap or neem oil.
Stunted growth
Why it happens
This may be due to poor soil quality or lack of nutrients.
How to fix it
Fertilize with a balanced fertilizer and ensure the plant is in nutrient-rich soil.
Care through the year
Spring
In spring, prune back any dead stems and begin a regular watering schedule as the plant starts to grow. Fertilize with a balanced fertilizer to encourage new growth.
Summer
During summer, ensure the plant receives adequate water, especially during hot spells. Monitor for pests and deadhead spent flowers to promote continuous blooming.
Fall
In fall, reduce watering as the plant prepares for dormancy. You may also want to cut back the foliage to encourage healthy growth in the spring.
Winter
In winter, protect the plant from frost if it is in a colder zone. Reduce watering significantly and avoid fertilizing until spring.
Toxicity & Safety
Agrimony is considered non-toxic to pets and children. However, ingestion of large quantities may cause mild gastrointestinal upset. Always consult a healthcare professional if ingestion occurs.
