For this article I was going to be a little nostalgic as I so missed my trip to Thomas Johnson at Mid-America Iris Garden, the visits to Lynda Miller’s of Millers Manor, the wonderful visits to Chad Harris at Mt Pleasant Irises, but Melissa and Bailey from Smokin’ Heights beat me to that…

The Whole “Scoop” on Fertilizing Iris

Customers often ask us, “How and when should I fertilizer my iris?”Fertilizer_NewBag2018web2 

The short answer (continue reading for the nitty-gritty): one month before bloom season, while the tulips are blooming, apply a low-nitrogen, well-balanced fertilizer, such as Schreiner’s 6-10-10 Controlled Release Iris Food. Keep the fertilizer several inches away from the rhizomes. In late September, fertilize again. That sums it up nicely, but perhaps you would like a bit more to chew on about the “what” and “when” of feeding your Iris. Read on for a more substantial serving of info on nurturing both your soil and your Iris.

There are four main nutrients that we must maintain in the soil: nitrogen, phosphorus, potassium, and calcium. The first three nutrients are found in most mixed fertilizers, and calcium can be purchased separately in the form of limestone. Nitrogen is necessary for new cell formation in all parts of a plant. Compared to other nutrients, nitrogen is typically the most lacking. A symptom of a shortage of nitrogen is yellow-green stunted growth. Potassium (potash) is necessary for strong roots and stems as well as deep flower color. A symptom of potash deficiency is weak stems and yellowing or browning leaf tips and edges. Phosphorus is necessary for development of roots and stems. This nutrient also stimulates fruit and seed production. A symptom of Phosphorus deficiency is red or purple discoloration of leaves.

Before applying any fertilizer to your garden, do a soil test to discover what your plants actually need. The best way to know how much, and at what proportion, to add nutrients to the soil is with a soil test. Simple soil tests can be purchased at garden supply centers. Once you determine what nutrients are lacking or are in abundance, you can amend the soil to correct most problems. Your soil test may also reveal a need to correct pH or add trace minerals, for example. Completing a soil test, and making modifications to your soil based on the results, is the preferred method to determine fertilizer amounts.

Fertilization of Iris is important to obtain best results, but must be done in moderation. The only thing Iris may resent more than underfeeding is overfeeding. Nitrogen, potash, and phosphorus are essential for Iris, but excessive nitrogen promotes lush growth that is more susceptible to rot diseases. If applied in concentrated form, do not allow the fertilizer to come in direct contact with foliage and roots, as the plant may be damaged or killed. Low-nitrogen fertilizers, such as 6-10-10, are ideal for the needs of Iris.

When to apply fertilizer to Iris:

1)   In the spring, about a month before bloom, apply a light application of fertilizer around the Iris clumps. This goes for dwarf iris, too, which bloom in March. Apply a low-Nitrogen fertilizer to your dwarf iris in mid to late February. Apply the same to your intermediate and tall bearded iris in intervals coinciding with the month before their bloom cycles.

2)  At planting, sprinkle a tablespoon of the fertilizer around the newly planted rhizome. Or, if preparing a large area for iris planting, incorporate ½ lb of a low-nitrogen fertilizer such as 6-10-10 per 50 ft2 (or 1 ½ oz per 10 ft2) to your garden bed.

3)  After your Iris bloom is another time you should fertilize them. Doing so keeps them healthy and in tiptop shape for better growth for the growing cycle later in the year. Wait a month or so after blooms have finished, or in the fall, with enough time before winter so the Iris have the proper nutrition they need going into their winter dormancy.

Here’s a little more info on the subject of fertilizing, including a short video with Ben Schreiner showing us how and when to feed your iris

Now that you’ve got the scoop on Iris nourishment, you can take the necessary action to feed your hungry Iris. Schreiner’s Gardens offers a specially formulated Iris food to help you provide balanced nutrition in the flower garden. Order now for summer and fall shipment.

Happy gardening!

My second stop on the 2019 tour of iris gardens in Oregon and Washington was the garden of Keith Keppel in Salem. For many years, Keith Keppel’s garden in Stockton was a must visit destination. With his retirement from the US post office, Keith made the huge move to Salem, Oregon. While he was…

By Ron Killingsworth and Patrick O’ConnorWhere, oh where, did that name originate? Iris names have always intrigued me. Some names are easy to figure out. Others defy reason. Another interesting subject is people’s names. Where in the world did the parents get the name they stuck on that poor child? Have you often wondered that? That subject…

Start the Season with Early Blooming Iris

Bearded Iris | Dwarf Iris

Dwarf iris can be seen blooming among the tulips, weather depending.

Easy to plant, easy to care for, easy to enjoy! That is the Iris. And such variety too! Variety of size, variety of bloom season, variety of color, variety of style. Isn’t success in life all about the choices we make? That simple maxim can apply to the realm of the flower garden too. The Iris offer such a host of choices, one is surely to find just the right color, or size, etc. Let’s talk about the breadth of bloom time, for example. The Miniature Dwarf Iris and the Standard Dwarf Iris are among the very first Iris to bloom. Weather depending, of course, they open up their diminutive blossoms (just 5 to 15 inches in height) approximately mid-March to early April (in most temperate zones), heralding the launch of another promising Iris season.

The Dwarf Bearded Iris are no less hardy than their taller, more robust cousins. Dwarf Iris, both Miniature and Standard types, propagate with strength and, once in bloom, stand up to the early spring frosts. There are several wonderful resources available which provide great detail on the origins of these hybrids. The Dwarf Iris Society is a good place to start for further links and leads on exploring the subject. Several Iris breeders today have introduced spectacular Bearded Iris cultivars in miniature.

Bearded Iris | Intermediate Iris

Intermediate Iris bloom early in the spring, often alongside tulips

As spring widens its embrace upon the land, weep not for the fading Dwarf Iris, for the Intermediate, Median, or Border Iris are opening on the garden scene! A bit taller than the tallest Dwarf, yet shorter than the shortest Tall Bearded Iris, they offer brilliant bloom to span the gap between March and May, a beautiful complement to the Cherry blossoms! The earliest blooming Tall Bearded Iris will overlap with the later-blooming Intermediate Iris, to create a seamless floral transition of color. Sprinkle in several mid-season and late-season Tall Bearded Iris around your garden, and the color show continues well into June.

A few moments spent casually mapping out the succession of Iris blooms in your garden will yield months of rainbow color from your ankles to above your hips! Dwarf, Intermediate, Tall Bearded, as well as Beardless Iris, are all planted in the summer months. Below is a simple chart, indicating approximate bloom times for Iris ranging from the Miniature Dwarf to the Tall Bearded, and including the Beardless Iris such as, Siberian and Louisiana. Bloom time is greatly dependent on weather conditions and gardening practices, however. For example, Reblooming Iris require regular extra fertilization, watering and dividing.

March

April

May

June

July/Aug/Sept/Oct

Min. Dwf. & Std. Dwf.

(5″ to 15″; 5cm to 28cm)

Intermediates & Border

(16″ to 27″; 40cm to 68cm)

Tall Bearded

(28″ to 48″;70cm to 122cm)

Tall Bearded & Beardless (such as, Siberian and Louisiana)

Reblooming Bearded Iris of all sizes

Intermediate Iris (IB) “Many Mahalos” (Aitken, 2003) blooms early, among the tulips.

If you are one who can hardly wait for the year’s Iris season to start, you have merely to plant some Dwarf Bearded Iris this summer. You will have Iris blooming with the first inkling of spring warmth. Even if you consider yourself simply a fan, a dabbler, a curious gardening newbie to the world of flowers, give the Dwarf Iris a try!
