Ruby Dayze Crabapple
A Ruby-Flowered Crabapple Built for Easy Color
Ruby Dayze Crabapple (Malus 'Ruby Dayze') lights up the spring landscape with vibrant ruby-pink blossoms set against handsome bronze-purple foliage, then carries the show into fall and winter with abundant glossy dark-red fruit that feeds the birds. Bred for strong disease resistance, it sidesteps the leaf-spotting and defoliation that plague older crabapples, staying clean and attractive all season. At a manageable 15 to 20 feet, it's a reliable, low-fuss choice for yards and boulevards alike. Whether you're adding spring color in Edina, a four-season specimen in Woodbury, or a tough boulevard tree in St. Paul, Ruby Dayze delivers dependable beauty with minimal care.

Ruby Dayze Crabapple Uses in Minnesota Landscapes
Spring Flowering Specimen
The ruby-pink spring bloom against bronze-purple leaves makes Ruby Dayze a standout focal point on a front lawn or by an entry in Edina or Plymouth. Its mid-size, rounded form suits most residential yards without overwhelming them.
Four-Season Interest and Bird Food
After the flowers fade, glossy dark-red fruit holds on the branches into winter, providing food for cedar waxwings, robins, and finches and adding color to the snowy landscape. The persistent fruit means little messy drop on the lawn.
Tough Boulevard Tree and Apple Pollinator
Disease-resistant and salt-tolerant, Ruby Dayze is a solid boulevard and street-side choice. As a flowering crab it also makes an excellent pollination partner for nearby eating apples like Honeycrisp and Haralson.
Best Time to Plant Ruby Dayze Crabapple in Minnesota
Crabapples are deciduous, so you have two good planting windows in the Twin Cities:
Spring (late April–May), once the ground has thawed, is excellent — the tree gets the full growing season to establish before its first winter.
Fall (September–mid-October) also works well. Plant at least six weeks before the ground freezes so roots can settle in. Avoid mid-summer planting when heat stress is highest, and never plant into frozen ground.
How to Plant Ruby Dayze Crabapple
- Dig wide, not deep — the hole should be 2–3 times the root ball width but only as deep as the ball itself. In heavy clay, dig even wider.
- Check drainage — if water pools in the hole, break through clay hardpan or mound-plant slightly to keep roots out of standing water.
- Backfill with the native soil mixed with 20–30% compost. Don't create a pure-compost "container" in clay.
- Set the tree so the top of the root ball sits at or just above grade. Allow room for the 12–18 foot mature spread.
- Build a 3–4 inch water basin around the root zone to direct water to the roots; flatten it before winter.
- Mulch with 2–3 inches of shredded bark or wood chips, kept 2 inches from the trunk, and wrap the young trunk to deter rabbits and deer.
Watering Ruby Dayze Crabapple in Minnesota
First Year Watering Schedule
Weeks 1–2: water every 1–2 days, deep and slow. Month 1–2: every 3–4 days. Month 3 through fall: every 5–7 days during active growth, less when rainfall is adequate. Stop watering 2–3 weeks before the ground freezes in late October so the tree can harden off for winter.
After Year One
Established Ruby Dayze Crabapple is fairly tough and drought-tolerant, needing supplemental water mainly during extended dry spells (2+ weeks with no rain). Water deeply to 6–8 inches every 7–14 days during drought, and let natural rainfall do most of the work.
Will Ruby Dayze Crabapple survive a Minnesota winter? Yes — it's hardy to about -30°F and well adapted to the Twin Cities.
Is it messy? Not very — the small dark-red fruit is persistent, meaning it clings to the branches into winter rather than dropping in a sticky mess, and the birds clean up much of what falls.
Does it resist disease? Yes — Ruby Dayze was selected for good resistance to apple scab and other crabapple diseases, so it stays cleaner and healthier than older varieties through Minnesota's humid summers.
Can it pollinate my apple tree? Yes — flowering crabapples are excellent pollinators for eating apples that bloom at the same time, such as Honeycrisp and Haralson.

How Many Ruby Dayze Crabapples Do I Need?
Ruby Dayze works best as a specimen — one tree with 14–18 feet of clear width anchors a front yard. For an informal flowering row along a driveway or property line, space trees 15 feet on center (a 60-foot run takes 5 trees). A group of 3 set 14–15 feet apart on a larger lawn doubles as a spectacular spring show and a winter bird-feeding station.
Ruby Dayze Crabapple Season-by-Season in Minnesota
- Spring: Vibrant ruby-pink single flowers open against bronze-purple new foliage in mid-May, alive with bees and pollinating nearby apple trees.
- Summer: Clean bronze-purple foliage holds its color on a tidy rounded crown — no mid-summer scab defoliation thanks to the bred-in disease resistance.
- Fall: Foliage deepens to rich bronze-purple while heavy clusters of glossy dark-red fruit color up.
- Winter: Persistent dark-red fruit decorates the snowy branches and feeds cedar waxwings, robins, and finches deep into the cold months.

Is Ruby Dayze Crabapple Right for Your Yard?
Ruby Dayze wants full sun (6+ hours) and adapts to nearly any Minnesota soil — clay-loam, urban fill, salted boulevard strips — in a manageable 15–20 foot package with genuine disease resistance. Protect young trunks from rabbits and deer in high-pressure yards. It's not a fit for shady sites (bloom and foliage color both fade) or for anyone who wants zero fruit — choose fruitless Spring Snow for a completely clean patio tree.
