Agastache Plant Care
Soil
Agastache care and soil do not need fertile soils to grow. You can grow Agastache in lean soil with a low level of nutrients. You can add some sand to your loamy soil to improve it for expansion.
The important thing is that Agastache grows in well-drained soil. So whether you grow it indoors or outside, ensure the soil drains well.
Lighting
Depending on where you live, the Agastache flower grows well in raised beds in warm climates in the full sun.
It can tolerate desert climates, but it helps to provide shade, especially in the afternoon, to prevent foliage burning.
Most outdoor plants in the species thrive in arid climates and are sure to attract hummingbirds to your garden. These plants are, to some extent, drought tolerant.
Watering
The Agastache loves deep watering with moist soil but must not remain wet the whole time. Hence, you can water deeply and leave the soil to dry between your watering.
Too much water will result in root ball rot, killing your indoor plant. You may need to water more in the hot sun to keep those tubular flowers looking great.
For indoor plants, we recommend investing in a moisture meter.
Temperature and Humidity
Compared to most other outdoor plants, Agastache thrives in high temperatures and can flourish in spots with afternoon sun.
However, high humidity is unsuitable for this plant as it will remain moist, and the leaves will turn yellow.
During cold seasons, the plant needs winter guards as the roots need to remain dry.
For this reason, you can add gravel around the plant base or a mulch barrier to prevent the roots from freezing.
Fertilizer For Agastache Plants
Your plant does not need added feeding, but you can provide well-rotted manure, organic matter, or pine needles in the fall for winter protection.
Doing this will help with new growth in spring.
Even if your plant is cold-hardy, we still recommend providing your plant with mulch protection at the base to prevent root rot.
Pruning
- Pinch new growth in spring to encourage bushier growth.
- Deadheading spent flowers helps maintain tidiness and prevents prolific self-seeding.
- For perennials, cut back by about one-third in spring to promote new growth. Avoid excessive pruning in midsummer to protect against winter survival issues.
- As an annual, continuous pinching and deadheading throughout the season is suitable.

Propagating Agastache
You can propagate your plant in mid-spring or fall using crown division, cuttings, or seed heads.
How to Grow Agastache from Seeds
Planting seeds is a straightforward and cost-effective way to grow these lovely herbaceous perennials. Here are step-by-step instructions on how to plant Agastache seeds:
- After the last frost date, plant seeds in your area in spring or early summer.
- Fill trays or pots with seed starting mix, scatter seeds evenly, and lightly press into the soil.
- Water gently, keeping the soil moist but not soggy, and cover with clear plastic to maintain humidity.
- Place in a bright location with indirect sunlight or use grow lights for illumination.
- Maintain consistent warmth around 70°F to 75°F (21°C to 24°C) with a seed heating mat if needed.
- Check soil moisture regularly and remove plastic cover once seedlings emerge.
- Transplant seedlings into larger pots or gardens after they develop true leaves.
- Space according to variety’s recommended spacing and ensure well-draining soil in sunny locations.
- Harden off seedlings outdoors for about a week before planting in the garden.
Growing Agastache from Cuttings
- Select a healthy, mature Agastache plant in early spring or summer.
- Use clean, sharp shears to take 3 to 5-inch stem cuttings below a node.
- Remove lower leaves, leaving a few at the top to reduce moisture loss.
- Optionally, dip cut ends in rooting hormone powder to aid root growth.
- Plant cuttings in well-draining potting mix in pots or trays, ensuring good soil contact.
- Water thoroughly and cover with clear plastic to maintain humidity.
- Place in bright, indirect light and check for root growth regularly.
- Once roots develop, transplant them into larger pots or garden beds.

Agastache Pest Management
Agastache plants generally resist pests, making them valuable to any garden. However, they can be susceptible to certain diseases and pests.
One common issue is fungal diseases, which can occur if the plant crown gets wet, so avoiding watering the foliage and ensuring good air circulation is essential.
To prevent root rot, maintain well-draining soil by removing debris and adding sand or soil amendments if necessary.
Look for potential pests like aphids, spider mites, or powdery mildew, and promptly address any infestations with organic or chemical treatments as needed.
