Flowering Quince

Overview

Flowering quince is a tough, easygoing deciduous shrub in the rose family, and it opens its flowers in early spring before a single leaf appears, so it's a cheering sight after winter. The blooms arrive in red, pink, orange, and white along thorny stems that have already come through cold down to -29°F (-34°C). Once the flowers fade, hard apple-like fruit forms and ripens through fall.

Best of all, it asks very little of you. The shrub grows at a moderate, unhurried pace into a dense, 6 to 12 foot (1.8 to 3.7 m) mound, copes with dry stretches once it has settled, and takes clay, sand, or rocky ground in its stride. The one thing it can't abide is alkaline soil, which turns the new leaves yellow and starved for iron, but that's an easy thing to put right.

The thorns that make pruning a gloved task also turn flowering quince into a useful barrier hedge, thick enough to slow foot traffic and welcoming to nesting birds. Give it room to spread well away from paths, and beyond a yearly trim once the flowers finish, it will pretty much look after itself.

Care

The short version: give it full sun to part shade and well-drained soil that leans acidic to neutral, and once it's established you only need to water through long dry spells. Prune as soon as it finishes blooming, because next year's flowers form on this year's old wood.

Light

Give it full sun for the fullest flush of bloom, though it will accept partial sun or partial shade without much grumbling. The more sun it soaks up, the more flowers you'll be rewarded with come spring.

Water

While a young plant is settling in, water it every 7 to 14 days and keep the soil at medium moisture. After it's established it turns mildly drought tolerant, so it only really needs a drink during a long dry spell.

Soil

Plant it in well-drained loam, though it cheerfully adapts to clay, sand, and rocky ground too. Aim for a pH between 5.5 and 7.0, on the acidic to neutral side, since alkaline soil leaves the leaves yellow and short on iron.

Temperature

This is a wonderfully cold-hardy shrub that copes with anything from -29°F to 95°F (-34°C to 35°C). Winter rarely bothers it, which is part of why it bounces back to bloom so early each spring.

Humidity

Everyday outdoor humidity is all it asks for, so there's no number to chase here. Good airflow counts for more, because crowded, damp branches are how leaf spot and scab get their start.

Feeding

Feed it in early spring with a balanced slow-release shrub fertilizer or a layer of compost, and once a season is plenty. Keep a light hand, since too much nitrogen pushes soft growth that both fire blight and aphids are drawn to.

Pruning

Prune it right after flowering, because the blooms form on old wood and cutting later snips off next year's flowers. Take out any dead, diseased, or crossing branches, shape it gently, and pull root suckers as they appear to keep it from wandering.

Repotting

An in-ground shrub never needs repotting, and even container plants are stepped up only rarely. Move it to a bigger pot when roots circle the drainage holes, water runs straight through, or a potted plant simply stops growing.

Size & spacing

Look forward to a mature mound around 6 to 12 feet (1.8 to 3.7 m) tall and 6 to 10 feet (1.8 to 3 m) wide. Give it that full spread so air can move through the dense, thorny growth and disease has a hard time taking hold.

When to plant

Flowering quince sets its buds on old wood, so the whole calendar turns on that one gentle rule. Plant in spring or fall, enjoy the blooms in early spring before the leaves unfurl, and do any pruning in the short stretch right after flowering. The hard fruit comes along afterward and ripens through the fall.

Troubleshooting

Most flowering quince troubles surface in spring, when wet weather encourages disease and soft new growth tempts pests. Get to know the early signs below and you can step in calmly before anything spreads. Match what you're seeing, then act while it still does the most good.

Severe

Shoot tips turning black and curling like a shepherd's crook

Try not to panic if you spot this. It's fire blight, a bacterial illness that travels through the rose family and slips in through open spring flowers, blackening the blossoms and shoot tips and bending them over as the dieback works downward. You can get ahead of it: during dry weather, cut the affected wood out well below the damage, wipe your tools with bleach or alcohol between snips, and burn or bin the prunings instead of composting them.

Fix:

  • Prune out blighted wood 8 to 12 inches below visible damage during dry weather
  • Disinfect pruning tools between cuts with 10 percent bleach or 70 percent alcohol
  • Remove and destroy infected prunings; do not compost
Setback

Leaves fading to yellow while the veins hold their green

When the youngest leaves fade to yellow while their veins stay green, the plant is struggling to take up iron, and the cause is almost always alkaline soil. Flowering quince really does not get along with a high pH, so this one is easy to read once you know it. Test the soil, and if it comes back alkaline, ease the pH toward neutral with organic matter and elemental sulfur over time. A dose of chelated iron will green things up quickly while that gentler fix settles in.

Fix:

  • Test and lower soil pH toward acidic to neutral
  • Apply chelated iron as a short-term correction
  • Amend with organic matter and elemental sulfur over time
Cosmetic

Spots on the leaves and rough scabs on the fruit

A damp spring can bring on fungal leaf spot and apple scab, which dot the leaves with dark rings and leave the fruit rough and corky. It looks worse than it is, and even early leaf drop won't do lasting harm. Gather up the fallen leaves and fruit, open the shrub up by thinning crowded branches once it has finished blooming, and only reach for a labeled fungicide if a year turns truly bad.

Fix:

  • Rake up and dispose of fallen infected leaves and fruit
  • Improve air circulation by thinning crowded branches after flowering
  • Apply a labeled fungicide in spring if infection is severe
Cosmetic

New shoots curling up with sticky residue and small bugs

Tender new shoots are a magnet for aphids, and now and then bumpy scale settles onto the stems and twigs too. Both leave behind a sticky honeydew that darkens into black sooty mold, which is harmless even if it looks grubby. Knock the aphids off with a firm jet of water, dab insecticidal soap or horticultural oil on the leaf undersides, and give stubborn scale another pass of oil. A happy, well-watered plant shrugs these off, so keeping yours healthy is half the battle won.

Fix:

  • Spray off aphids with a strong jet of water
  • Apply insecticidal soap or horticultural oil, covering leaf undersides
  • Treat persistent scale with horticultural oil

Toxicity

You really have nothing toxic to fret over here. Flowering quince stays off every pet poison list, and even the fruit is safe to eat once it's cooked. The only genuine hazard is mechanical, since the sharp thorns can scratch people and pets, so wear gloves when you handle it and plant it clear of paths and play areas.

Safe for

People · Cats · Dogs · Horses · Rabbits · Livestock · Birds

Cats None

You can breathe easy with cats around. Flowering quince isn't on the ASPCA toxic list, so a curious cat that swats at the leaves won't be poisoned. The only thing worth a thought is a scratch from the thorns.

Dogs None

If your dog grabs a leaf or a dropped fruit, there's no poison in it to harm them. Just keep the sharp thorns in mind, since a pointed spine can nick a curious nose or paw.

Horses None

Horses are welcome to graze near a flowering quince without any worry, because the plant holds no toxin that troubles them. The only thing to watch is the spines, which can scratch a soft muzzle.

Rabbits None

A rabbit that nibbles the foliage faces no risk of poisoning at all. The thorns are the single thing to keep in mind around small, soft-skinned pets.

Livestock None

Cattle, goats, and sheep can graze right beside this shrub in safety, since it carries nothing that would poison them. The dense, thorny stems are the only reason you might fence it off.

Birds None

Birds are perfectly safe around the plant and its fruit, and the thorny tangle even gives them sheltered nesting cover. There's simply no toxic part to keep them away from.

People None

Raw, the fruit is hard and sour, but it cooks down beautifully into jams, jellies, and preserves, so nothing here will poison anyone. The thorns are the genuine hazard, so slip on gloves and long sleeves before you prune.

Stems bear sharp thorns and spines that can scratch or puncture skin, so wear gloves and long sleeves when pruning or handling, and site away from walkways and pet or play areas.

Varieties

A few cultivars are worth getting to know, whether you'd love the classic multicolor bloom or a modern thornless type that skips the fruit. These are the ones to ask for by name.

'Toyo-Nishiki'

You'll see red, pink, and white flowers open together on it, sometimes side by side on one branch.

Double Take 'Pink Storm'

A gentle, thornless and fruitless choice whose full double pink blooms, packed with 29 to 40 petals, look much like camellias.

Double Take 'Scarlet Storm'

Another thornless and fruitless one, this cultivar offers deep double scarlet-red flowers.

Double Take 'Orange Storm'

It keeps that same easy thornless, fruitless habit and adds double flowers in a warm orange.

How to propagate

Flowering quince is wonderfully easy to multiply, and you have three good paths to choose from depending on how much patience you have and what the plant offers you to work with.

Stem cuttingsModerate

Mid-July to early fall for semi-hardwood cuttings · Several weeks to root, then transplant the following season

Don't be shy about this one. Take firm semi-hardwood cuttings of this season's growth from mid-July into early fall, and a dip of the cut ends in rooting hormone will tip the odds your way. They take several weeks to root, then settle in and are ready to move out the following season.

LayeringEasy

Spring through summer · Roots form over a season; ready to separate the following autumn or spring

Mound layering is a forgiving way to start more of this low, densely branched shrub, and you can begin anytime from spring through summer. The buried stems take a full season to root, so they'll be ready to cut loose and replant the following autumn or spring.

DivisionModerate

Dormant season (late fall to early spring) · One season to reestablish

The shrub sends up rooted suckers from its base, and during the dormant season from late fall to early spring you can dig and split those away to make whole new plants. Give each division about a season to find its feet, and it will.

Myths

Myth

Flowering quince will poison a curious cat or dog.

Reality

You can set this worry aside. Chaenomeles speciosa never turns up on the ASPCA toxic-plant lists, and it's considered non-toxic to both cats and dogs. The real household hazard is the thorns, not poison. A pet that brushes the stems might pick up a scratch, but one that tastes a leaf will be just fine.

Myth

Since the fruit is so hard and bitter, it must be toxic.

Reality

Raw, the fruit is rock-hard and sharply sour, which is just why folks assume it's off the menu. Cooked, it's perfectly safe to eat, and it makes wonderful jams, jellies, and preserves.
