Choosing the Right Location in Your Garden

It’s essential to find that perfect spot in your garden where your agastache plants will thrive and transform your outdoor space into a colorful spring paradise. To do this, you need to consider two main factors: sunlight requirements and soil preferences.

Agastache plants generally prefer full sun, which means they should receive at least six hours of direct sunlight per day. However, some varieties can tolerate partial shade, especially in hotter climates.

It’s also important to plant your agastache in well-draining soil, as they are susceptible to root rot if left in standing water. You can improve your soil’s drainage by adding organic matter such as compost or aged manure.

To help you choose the ideal location for your agastache plants, consider the following table that shows the optimal conditions for some popular agastache varieties:

By considering the sunlight requirements and soil preferences for each variety, you’ll be able to find the perfect spot in your garden for your agastache plants to flourish. With the right location, these plants will reward you with stunning blooms and a vibrant spring garden.

Proper Planting Techniques

Once you’ve found the perfect spot for your plants, it’s time to master the proper planting techniques to ensure they thrive and brighten up your outdoor space.

Soil preparation is crucial for the healthy growth of your agastache plants. Start by loosening the soil to a depth of about 12-18 inches and mix in some organic matter, such as compost or well-rotted manure, to improve drainage and provide essential nutrients. Make sure the soil is well-draining, as agastache plants don’t like to sit in wet soil. If you have heavy clay soil, consider adding some sand or perlite to improve drainage.

When it comes to planting, dig a hole that’s about twice the width of the root ball and deep enough so that the top of the root ball is level with the soil surface. Gently remove the plant from its container, being careful not to damage the roots, and place it in the hole. Fill in the space around the root ball with soil, firming it down as you go to eliminate air pockets.

Water the plant thoroughly to help settle the soil and establish a good watering schedule. Agastache plants prefer consistent moisture, so water them regularly, especially during dry spells, but be careful not to overwater. A layer of mulch around the base of the plant can help retain moisture and suppress weeds.

With proper planting techniques and care, your agastache plants will reward you with a stunning display of color and fragrance in your spring garden.

Caring for Your Agastache

To keep your vibrant agastache flourishing, it’s essential to provide proper care throughout the growing season. Agastache maintenance begins with paying close attention to soil considerations. This plant thrives in well-draining soil, so ideally, you should use a mixture of organic matter, such as compost or aged manure, and gritty materials like sand or perlite to improve drainage.

Additionally, it’s crucial to water your agastache regularly but avoid overwatering, as soggy soil can lead to root rot. As a general rule, aim for about 1 inch of water per week, either through rainfall or supplemental watering. Fertilizer is not always necessary for agastache, as they can tolerate a range of soil fertility levels.

However, if you find that your plants are struggling or not growing as vigorously as they should, you can apply a balanced, slow-release fertilizer in the spring, following the package instructions. Pruning is another essential aspect of agastache care, which encourages bushier growth and continuous blooming. Regularly remove spent flower spikes and trim back any leggy growth, ensuring that your agastache stays healthy and attractive throughout the season.

With proper care and maintenance, your agastache will reward you with a stunning display of color and fragrance in your spring garden.

Attracting Pollinators and Wildlife

Attracting pollinators and wildlife to your garden is not only beneficial for the environment, but it also adds life and beauty to your outdoor space.

By planting Agastache, you’ll provide a valuable food source for bees, butterflies, and hummingbirds, while also enjoying their delightful presence.

Combine Agastache with companion plants to create a diverse and inviting habitat that supports a healthy ecosystem and enhances the overall aesthetic of your garden.

Benefits for Bees, Butterflies, and Hummingbirds

You’ll find that Agastache plants are a magnet for bees, butterflies, and hummingbirds, offering essential nectar and pollen for these vital pollinators. By incorporating these beautiful plants into your fall planting guide, you’ll be providing pollinator benefits such as valuable nectar sources and much-needed shelter for these amazing creatures. As your garden comes alive with buzzing bees, fluttering butterflies, and darting hummingbirds, you’ll know that you’re making a positive impact on the local ecosystem.


Agastache plants provide a rich source of nectar and pollen for a variety of bee species, helping to support their nutrition and overall health. The vibrant colors and sweet fragrance of Agastache flowers attract bees, encouraging them to visit your garden and pollinate other plants in the process. By planting Agastache, you’re contributing to the conservation of bees, which are essential for pollinating the majority of the world’s food crops.


Agastache flowers serve as an important nectar source for butterflies, providing them with the energy they need to lay eggs and continue their life cycle. Butterflies are also attracted to the bright colors and enticing scent of Agastache plants, making your garden a haven for these beautiful insects. By supporting butterfly populations, you’re promoting biodiversity and helping to maintain the balance of your local ecosystem.


Agastache’s tubular flowers are perfectly shaped for hummingbirds to feed on their nectar, providing them with essential nutrients and energy. The bright colors of Agastache flowers, particularly reds and oranges, are highly attractive to hummingbirds, drawing them into your garden. By offering a reliable source of nectar, you’re helping to support hummingbird populations, which in turn helps to pollinate a variety of plants in your garden and beyond.

Companion Planting Ideas

When planning your landscape, consider incorporating companion plants that complement and support the growth of your Agastache varieties. Agastache pairings not only create striking visual interest but also promote the overall health and vigor of your garden. By choosing plants with similar growing requirements, you’ll ensure that your Agastache and its companions thrive together.

Color combinations play a significant role in creating a stunning Agastache-centric garden. Pair Agastache with plants like Russian Sage, Echinacea, and Salvia for a mix of vibrant purples and blues. For a more striking contrast, consider planting Agastache alongside bright yellow flowers like Coreopsis or Black-Eyed Susans.

Don’t forget to include plants with interesting foliage, such as ornamental grasses and heucheras, to add texture and depth to your garden design. Ultimately, the key is to select plants that share Agastache’s love for well-drained soil and full sun exposure, ensuring a thriving and beautiful spring garden.


In conclusion, you’ve got everything you need to successfully grow agastache in your garden. Just remember to choose the right variety, location, and follow the proper planting techniques.

As your agastache thrives, you’ll not only enjoy its beauty but also attract pollinators and wildlife. So, go ahead and plant some agastache this fall for a stunning spring garden you can be proud of!
