Amethyst Creek Farm
Growing Beautiful Bearded Irises
Take a Little Beauty Home™

Thank you for choosing an Amethyst Creek Farm iris.

Every rhizome we ship has been carefully selected and inspected before leaving our farm. Bearded irises are among the easiest and longest-lived perennials you can grow, rewarding gardeners with beautiful blooms for decades.

The recommendations in this guide combine established horticultural practices with what we've learned growing thousands of cultivars here at Amethyst Creek Farm in Middleton, Idaho. Every garden is different, so think of these as guidelines rather than rigid rules. Your local climate, soil, and growing conditions should always guide your gardening decisions.

Upon Arrival
Open your package as soon as possible and compare the contents with your order.
Healthy rhizomes may have:

These are all normal after lifting, cleaning, storing, and shipping.

If you cannot plant immediately, store your rhizomes in a cool, dry, well-ventilated location out of direct sunlight. Do not store them in sealed plastic bags or damp environments.

Understanding Rhizome Size
One of the most common questions we receive is, "Why are some rhizomes larger than others?"

The answer is simple—not all irises naturally produce the same size rhizome.
Rhizome size varies depending on:

Some cultivars naturally produce large, heavy rhizomes, while others remain much smaller throughout their lives. A smaller rhizome does not indicate a less healthy plant or poorer bloom performance.
Amethyst Creek Farm is also a relatively young farm. While we now grow thousands of cultivars, many of our plantings are still becoming established in their permanent locations. As our fields continue to mature, many varieties will naturally produce larger increases and greater quantities of saleable rhizomes.

Rather than focusing solely on size, we focus on shipping healthy, vigorous, correctly identified rhizomes capable of establishing quickly and providing years of enjoyment.
We believe the true measure of an iris isn't the size of the rhizome when it arrives—it's the beauty it brings to your garden for years to come.

Our Bloom Guarantee
We take great care to ensure every iris is accurately labeled and true to its registered cultivar.

If your iris blooms and you believe it is not the variety you ordered, simply contact us.
Whenever possible, we will:

Your confidence in purchasing from Amethyst Creek Farm is important to us, and we proudly stand behind every plant we sell.

When to Plant
Bearded irises are traditionally planted from midsummer through early fall after blooming has finished.
However, they can generally be planted anytime the ground remains workable and until the ground freezes. In extremely hot and humid areas, it is best to pot irises to protect them from rot.

For colder envrionrments, the strongest establishment, we recommend planting at least six weeks before your area's first hard frost. This allows the rhizome to begin producing a new root system before winter dormancy.

Spring planting is also successful, although newly planted rhizomes may require additional watering and may take longer to produce their first blooms.

What to Expect After Planting
Don't be concerned if the original roots begin to dry out or die back.

By the time your iris arrives, it has often been out of the ground for several days. Those original roots have already served their purpose and may no longer remain active. They are usually dead and will not come back.
You have two options:

Either method works well. We recommend trimming as leaving root material can lead to rot as the roots decay.

With adequate moisture, healthy rhizomes generally begin producing new feeder roots within one to two weeks. These new roots become the plant's permanent root system.

Choosing the Right Location
Most bearded irises bloom best with at least six hours of direct sunlight each day.
In cooler climates, full sun generally produces the best results.

In areas where summer temperatures regularly exceed 100°F, irises often benefit from:

Dark-colored blooms may also retain their color longer when protected from intense afternoon sun.

Choose a location with good air circulation and excellent drainage.

Soil & Drainage
Bearded irises thrive in loose, well-drained soil but adapt well to many soil types. Heavy clay soils benefit from raised beds, berms, or other improvements that increase drainage. Sandy soils may benefit from added organic matter to improve moisture retention. A soil pH between 6.5 and 7.0 is generally ideal, although irises tolerate a wider range. Excellent drainage is far more important than perfect soil.

Planting Depth
One of the most common questions we receive is whether iris rhizomes should be planted above or below the soil surface.

The answer is simple:
Both methods are correct—they're simply suited to different climates.

Moderate or Moist Climates
Gardens with moderate temperatures, higher humidity, or consistently moist soils generally perform best with the top of the rhizome exposed or just barely visible above the soil surface. This improves airflow around the rhizome and helps reduce the risk of rot.

Hot or Extreme Climates
Gardens that regularly experience prolonged summer temperatures above 100°F, severe winter cold, or both often benefit from planting the rhizome approximately ½ to 1 inch below the soil surface. This is the method we use here at Amethyst Creek Farm in Idaho, where we experience both hot summers and freezing winters. A light covering of soil helps moderate temperature extremes while still allowing vigorous growth. Regardless of planting depth, excellent drainage remains the single most important factor.

Garden where you live—not where someone else gardens.

How to Plant
Dig a shallow hole wide enough to comfortably spread the roots. If trimmed, then dig a hole large enough to put the rhizome at the proper level. Position the rhizome at the appropriate depth for your climate and spread the roots naturally beneath it.

Firm the soil gently to eliminate large air pockets.

Water thoroughly after planting. You should only water once every week to ten days. Irises prefer to dry between waterings.

Plant Spacing
Recommended spacing:

Closer spacing creates fuller beds more quickly, while wider spacing allows plants to grow longer before requiring division.

Watering Newly Planted Irises
Water thoroughly immediately after planting. Continue monitoring soil moisture during the first several weeks while new roots develop. Until new roots form, the rhizome depends on available soil moisture to become established.

Watering Established Irises
Established irises prefer deep, occasional watering rather than frequent shallow watering. Allow the soil to dry between waterings.

Water requirements vary depending on:

Growing Irises in Containers
Bearded irises grow exceptionally well in containers and are an excellent choice for patios, collectors, or gardeners with limited space. Container-grown irises require more routine care than those planted in the ground. Because pots dry out much more quickly, monitor soil moisture regularly and water whenever the soil begins to dry. While irises dislike constantly wet conditions, they also should not remain completely dry for extended periods during active growth.
Use a well-draining potting mix and containers with adequate drainage holes.
Since their growing space is limited, container-grown irises become crowded more quickly and generally require division more often than garden-grown plants.
Inspect containers annually and divide when:

Many container-grown irises benefit from fresh soil and division every 2–3 years.

Fertilizing
Bearded irises are not heavy feeders and generally perform best with a low-nitrogen fertilizer.

We recommend a fertilizer with an analysis similar to 5-10-10, or another formulation where the nitrogen (the first number) is lower than the phosphorus and potassium. These fertilizers encourage healthy root and rhizome development while supporting strong bloom production.

Fertilizer may be applied:

Apply fertilizer around the plant rather than directly against the rhizome, and water it into the soil according to the manufacturer's directions.
Avoid excessive nitrogen. High-nitrogen fertilizers can produce lush foliage at the expense of blooms and may also increase susceptibility to soft rot and other diseases.
If you're unsure what your soil needs, a soil test is the best way to determine nutrient levels and whether pH adjustments are beneficial.
Remember, healthy soil grows healthy irises. Fertilizer is intended to supplement good soil—not replace it.
After Bloom
Remove spent bloom stalks after flowering.
Healthy green foliage should remain until it naturally declines or becomes damaged or diseased.
The leaves continue producing energy that supports next year's blooms.
Dividing
Most bearded irises benefit from division every 3–5 years, although timing varies by cultivar and growing conditions.
Divide when:

Late summer through early fall is generally the ideal time.
Fall & Winter Care
Remove dead foliage and plant debris after frost.
Avoid heavy mulch directly over rhizomes.
In climates with repeated freeze-and-thaw cycles, a light winter covering after the ground freezes may provide additional protection.
Common Problems
Monitor your plants for:

Most problems can be prevented with good drainage, proper spacing, good air circulation, and clean garden practices.

What to Expect During the First Year
Newly planted irises spend much of their first season establishing roots and adapting to their new environment. Some bloom the following spring. Others may require an additional growing season. Both are perfectly normal. As plants mature, you'll often notice improvements in bloom size, branching, bud count, substance, and overall garden performance. Remember, gardening is a long-term investment. The beauty of an iris collection grows with each passing season.

Amethyst Creek Farm
Growing Beautiful Daylilies
Take a Little Beauty Home™
Welcome
Thank you for choosing an Amethyst Creek Farm daylily.
Daylilies are among the easiest, most rewarding perennials you can grow. They are adaptable, dependable, and capable of producing spectacular displays of color for decades with minimal care.
The recommendations in this guide combine established horticultural practices with what we've learned growing thousands of plants here at Amethyst Creek Farm in Middleton, Idaho. Every garden is unique, so use these recommendations as guidelines and adapt them to your own climate and growing conditions.
Upon Arrival
Open your package as soon as possible and compare the contents with your order.
Healthy daylily fans may have:

These conditions are normal after lifting, cleaning, storing, and shipping.
If you cannot plant immediately, keep the roots cool and slightly moist. Store them in a cool location out of direct sunlight. Unlike iris rhizomes, daylily roots should not be allowed to dry completely for extended periods.
Understanding Fan & Root Size
One of the most common questions we receive is, "Why are some daylilies larger than others?"
Just like irises, not all daylilies naturally grow the same size.
Plant size varies depending on:

Some cultivars naturally produce large, robust fans and heavy root systems, while others remain more compact.
At Amethyst Creek Farm, many of our daylilies are still becoming established in our fields. As our gardens mature, many cultivars will naturally produce larger divisions and stronger root systems.
Our priority is providing healthy, vigorous, correctly identified plants that establish quickly and perform well in your garden.
The true value of a daylily is measured by years of beautiful blooms—not by the size of the division when it arrives.
Our Bloom Guarantee
We carefully label every plant before it leaves our farm.
If your daylily blooms and you believe it is not the cultivar you ordered, simply contact us.
Whenever possible, we will:

We proudly stand behind every plant we sell.
When to Plant
Daylilies may be planted throughout much of the growing season whenever the ground is workable.
For best results, plant at least six weeks before your area's first hard frost so new roots have time to establish before winter.
Spring and early fall are generally the ideal planting times, but container-grown daylilies can often be planted successfully throughout the growing season with adequate watering.
What to Expect After Planting
It is normal for transplanted daylilies to experience a brief adjustment period.
Some older leaves may yellow or decline as the plant redirects its energy toward producing new roots and foliage.
Keep the soil evenly moist during establishment.
Healthy plants typically begin producing new roots within the first few weeks after planting.
Choosing the Right Location
Most daylilies perform best with at least six hours of direct sunlight daily.
In hotter climates, many cultivars appreciate afternoon shade, especially darker-colored flowers that may fade in intense sun.
Good air circulation helps reduce disease while encouraging healthy foliage.
Soil & Drainage
Daylilies are remarkably adaptable but perform best in fertile, well-drained soil rich in organic matter.
Unlike bearded irises, daylilies appreciate soils that retain moderate moisture while still draining well.
A soil pH between 6.0 and 7.0 is generally ideal.
Planting Depth
Plant the crown (where the leaves meet the roots) approximately 1 inch below the finished soil surface.
Spread the roots naturally outward and downward before backfilling.
Firm the soil gently around the roots to eliminate large air pockets.
Water thoroughly after planting.
Unlike iris rhizomes, daylily crowns should be covered with soil.
Plant Spacing
Spacing depends upon the mature size of the cultivar.
As a general guideline:

Proper spacing improves airflow and allows plants to mature without overcrowding.
Watering Newly Planted Daylilies
Water thoroughly immediately after planting.
During the first several weeks, keep the soil consistently moist while the new root system develops.
Unlike bearded irises, daylilies appreciate more consistent moisture during establishment.
Watering Established Daylilies
Established daylilies tolerate drought surprisingly well but perform best with consistent moisture.
During active growth and bloom, approximately one inch of water per week from rainfall or irrigation is generally sufficient.
Extended drought may reduce bloom count, flower size, and overall vigor.
Growing Daylilies in Containers
Daylilies adapt exceptionally well to containers.
Because containers dry much more quickly than garden soil, monitor moisture frequently during warm weather.
Water whenever the soil begins to dry.
Use a quality potting mix with excellent drainage and choose containers large enough to accommodate future growth.
Container-grown daylilies often require division every 3–5 years, depending on cultivar and container size.
Fertilizing
Daylilies benefit from regular but moderate fertilization.
We recommend using a balanced fertilizer or one with slightly lower nitrogen, such as 5-10-10 or 10-10-10.
Apply fertilizer:

Avoid excessive nitrogen, which encourages lush foliage while reducing flower production.
Healthy soil is always more important than heavy fertilization.
After Bloom
Remove spent flowers regularly to keep plants looking tidy and encourage continued blooming on reblooming cultivars.
Once an entire flower scape has finished blooming, cut it back near the base.
Leave healthy foliage in place throughout the growing season, as it continues producing energy for future blooms.
Dividing
Most daylilies benefit from division every 4–6 years, although vigorous cultivars may require more frequent division.
Divide when:

Early spring and early fall are generally the easiest times to divide.
Fall & Winter Care
Remove dead flower scapes after bloom.
After frost, remove dead or damaged foliage.
Dormant varieties naturally die back each winter.
Evergreen varieties may retain some foliage throughout mild winters.
Mulching may help moderate soil temperatures in colder climates.
Common Problems
Monitor plants for:

Most problems can be minimized through good sanitation, proper spacing, and adequate airflow.
What to Expect During the First Year
Like many perennial plants, newly planted daylilies spend much of their first season developing roots and adapting to their new environment.
Some varieties bloom immediately.
Others may bloom lightly during their first season and improve significantly the following year.
As plants mature, you'll often notice:

Patience is rewarded.
