Spring showers bring not only flowers! Slug and snail season is upon us and these slimy gastropods love, love, love to chomp away at iris and daylily foliage! This a friendly reminder to apply your preferred bait or exclusion barriers to control these pesky buggers.
Excessive foliar damage is not only aesthetically displeasing, but also diminishes photosynthetic activity and creates wounds that make plants more susceptible to attracting other pests and disease. So if you’re seeing slime trails and lots of holes in your foliage, it’s a great time to establish some control in the garden!
These pests are primarily active at night or on cool, cloudy days. Begin by tidying your garden by weeding and removing excess debris where slugs and snails love to hide and lay eggs. Bait applications do best following a spell of rain; an opportune time for gastropod activity. If you have furry friends that frequent your garden, be mindful to choose a pet-friendly bait. Exclusion barriers such as cracked filbert shells, plant cloches, and collars will also offer great protection.

Join us in celebration of our 96th year! This year the theme of our catalog centers around our home state of Oregon. Inside our 32-page print catalog, you will find stunning images of the breathtaking locations around our beautiful state, as well as dozens of eye-popping colorful iris. The names of our 2021 iris introductions, of course, take their inspiration from all things Oregon…. from the dramatic coastline on the western edge, to the wide open high dessert of the east, and everything in between.
Customers often ask us, “How and when should I fertilizer my iris?”
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. Approximately on month after bloom season, 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.
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.
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 Sylvain Ruaud In Italy iris hybridizing is not a new activity. But as you are about to find out, over the years it has taken its own — very original — dimension. Everywhere else in Europe it is men who have dedicated their lives to irises, certainly with enthusiasm and passion, but also as a…

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.
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.
Min. Dwf. & Std. Dwf.
(5″ to 15″; 5cm to 28cm)
Intermediates & Border
(16″ to 27″; 40cm to 68cm)
(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!
Do you grow Dwarf Iris? Share your comments below!
Last winter, during the long dark days, we pondered the spring. We asked ourselves, what could we offer to those lucky devils who live in warmer climes who were already up to their elbows in glorious warm soil by April? A few ideas took sprout, so to speak. Read on for more details.
Common wisdom recommends that bearded iris be planted in the summer months, which means that they will bloom the following spring. This year we’re offering six hardy reblooming bearded iris in biodegradable pots ready for planting in April! For best results, the threat of frost must have already passed and the soil must be soft enough to work.
By getting your potted irises in the ground now, you have increased your chances of seeing bloom this year. All the irises in this collection are also classified as reblooming iris. Under the right conditions, reblooming iris have a second bloom cycle in late summer or fall.
