Lavender: cut it the week the flowers fade

Prune English lavender the week its flowers fade — a third off, never into the bare wood it can't regrow from. Wait till autumn and it goes woody.

June 29, 2026

Penstemons: deadhead now, don't cut back

Deadhead penstemons all summer for months more bloom — but cut them back now and you risk losing the plant over winter. Here's what to do instead.

June 28, 2026

Penstemons: deadhead now, hard-prune in spring

Deadhead penstemons to the first leaf and they flower into October. But don't cut the plant back now — old growth shields the crown over winter.

June 27, 2026

Geums fading already? Cut the whole plant back

When geums fade to a trickle, snipping one stem at a time won't help. Cut the whole plant back to its leafy base in early July and a second flush follows.

June 26, 2026

Red valerian: cut it back before it seeds

Red valerian seeds into every wall and gravel crack. Cut the plant back hard after the first flush in late June — fewer seedlings, a second show.

June 25, 2026

Dahlias: that pointed 'bud' is a dead flower

Deadhead dahlias and they flower till frost. But the round bud is the next flower and the soft pointed cone is the spent one — cut the cone, not the bud.

June 24, 2026

Salvias rebloom till frost — if you cut them right

Don't shear salvias flat. Cut each spent spike to the new side shoots as the first flush fades, and border salvias rebloom from August to frost.

June 23, 2026

Don't deadhead alliums — leave the globes

You don't need to deadhead alliums. The spent globes dry into architectural seedheads — leave the foliage to feed the bulb, and lift crowded clumps now.

June 22, 2026

Pinks gone leggy? Shear the clump by a third

Deadheading pinks one bloom at a time won't stop them sprawling. The fix for leggy Dianthus is one late-June shear by a third — here's exactly how far to cut.

June 21, 2026

Leylandii: trim in summer, never into the brown

Leylandii regrows fast from green, never from brown. Trim a conifer hedge in summer to keep it dense — and learn the one cut it can't recover from.

June 20, 2026

Apples & pears: the summer cut, not the winter one

Trained apples and pears get their main prune in summer, not winter. Once this year's side shoots turn woody at the base, shorten them to build fruit.

June 19, 2026

The rock-rose cut that never grows back

Cistus won't reshoot from bare wood — one hard prune leaves a gap forever. After flowering, shear only the soft green tips. Here's the safe June cut.

June 18, 2026

Bridal wreath spiraea: the June-only cut

Bridal wreath spiraea takes the knife only right after its white flowers fade. Prune the summer-flowering kind now and you'll lose next spring's display.

June 17, 2026

A June trim makes a privet hedge twice as thick

Trim a privet hedge in mid-June, not just late summer, and it answers with dense, twiggy regrowth. Here's how hard to cut — and why one trim won't do.

June 16, 2026

Wisteria's summer cut: five leaves, not five feet

Wisteria summer pruning starts in late June: shorten this year's whippy shoots to five or six leaves so the plant builds flower buds, not more growth.

June 15, 2026

Aquilegia: cut back the tatty clump in June

Aquilegia foliage goes mildewed and tatty once it flowers. Cut the whole clump to the ground in June for fresh leaves — and far fewer seedlings.

June 14, 2026

Sweet peas stop the day you stop picking

Sweet peas quit the moment they set seed. Pick every bloom every day, and snip off any pod you missed, to keep the vine flowering into September.

June 13, 2026

Clematis: deadhead the early flowers for a repeat

The big May–June clematis flower again in late summer if you deadhead now — but only the early, large-flowered types. Here's the cut, and the one to skip.

June 12, 2026

Cresco tracks every plant's pruning window for you

Cresco keeps a pruning calendar for every plant you own, checks it against your local weather, and tells you the right week to cut — not guess.

June 12, 2026

Photinia Red Robin: cut now for a fresh red flush

A June trim makes Photinia Red Robin push out a flush of scarlet new leaves. Here's how far to cut, why secateurs beat the trimmer, and when to stop.

June 11, 2026

Why honeysuckle goes bare — the after-bloom prune

Honeysuckle that flowers only at the top isn't the wrong variety — it's a pruning job you do right after the blooms fade. Here's the cut that fixes it.

June 10, 2026

Deadheading Roses: Snap, Don't Cut Back

Deadheading roses by snapping the spent flower off, not cutting back to a five-leaflet leaf, gives faster repeat blooms all summer — here's why.

June 9, 2026

Catmint: shear the whole plant for a second flush

Catmint flops open in June. Don't stake it — shear the whole plant to a low mound as the first flush fades and you get a fresh second flush by August.

June 8, 2026

Should you cut lady's mantle back after flowering?

Cut lady's mantle back as the lime-green froth fades in June, before the seed ripens — stop a hundred seedlings and get fresh foliage by July.

June 7, 2026

Pruning Rambling Roses After Flowering

Rambling roses flower once, on old wood — so you prune right after the June show, not in winter. Here's the cut that keeps them blooming and in bounds.

June 6, 2026

A second flush of delphiniums, from one June cut

Cut delphiniums to the base as the first spires fade, and fresh shoots give a second flush by late summer. Here's the timing—and the mistake to avoid.

June 6, 2026

Deadheading Lupins for a Second Flush

Deadhead lupins as the main spike fades and the plant pushes side spikes for a second flush in late summer—and seed never drains the short-lived plant.

June 4, 2026

Beech Hedge Trim: The Late-June Window

Cut a beech hedge in May and the new leaves brown at the edges; cut it in August and it sulks all winter. The late-June window — and how to time it.

June 4, 2026

Tree Peonies After Flowering in Early June: The Deadhead That Saves Next May's Bowl, and the Cut That Would Kill the Shrub

Your tree peony has just dropped its dinner-plate blooms and the spent heads sag on woody stems. The temptation is to cut them back the same way you'd treat a herbaceous peony in autumn — and that's the cut that quietly kills the shrub. Tree peonies are woody. The grey stems carrying this spring's spent flowers are the same stems that will carry next May's, and the buds for 2027 are already forming in the bark axils right now. Deadhead the right way, watch the base for the herbaceous suckers most grafted plants throw in mid-June, and you keep a thirty-year show going.

June 3, 2026

Camellia After Flowering: The Mid-June Cutoff That Decides Next Spring's Bloom Count

Your camellia stopped flowering weeks ago. The petals fell, the bush turned back into a glossy green dome, and you mentally moved on. But there's a quiet fortnight between now and mid-June when the plant will accept a careful shape-and-thin — and after which every cut you make is removing one of next January's flowers. Bud differentiation begins in late June, and once it starts, the pruning year is closed until the petals fall again.

June 2, 2026

Aquilegia After Flowering in Early June: Why Cutting the Whole Plant to the Ground Buys You a Mildew-Free Summer

Your columbines have done their job — petals dropped, foliage browning at the edges, mildew creeping up the lower leaves. A single hard cut to the crown right now resets the plant: clean basal rosette by July, no muddy seedlings in 2027, and two or three extra years of life out of a famously short-lived perennial.

June 1, 2026

Climbing Hydrangea After Flowering in Early June: The Outward-Pointing Cut That Stops It Crawling Through Your Window

Climbing hydrangea has two kinds of shoot: the flat clingers that stay against the wall, and the elbow-out projectors that hold the lacecap flowers. By early June the projectors have done their job — and that's the only wood you should be cutting.

May 31, 2026

Deutzia After Flowering in Early June: The Two-Cut Combo That Saves Next May's Bridal Curtain

Your deutzia has just dropped a fortnight of starry white or pink-tinged blossom and the arching stems already look tired. The temptation is to wait, or to shear the whole shrub over like a hedge. Both choices cost you next May's display — because deutzia flowers on wood made last summer, and the shoots that will carry the 2027 show are already pushing out below the spent flowers. Get in now with two different cuts, in the right order, and you keep the cascade. Miss the window and you trade an arching curtain of bloom for a tired, gappy mound of leaves.

May 31, 2026

Foxgloves in Early June: The Cut That Buys a Second Flush — and Turns a Biennial Into a Three-Year Plant

Your foxglove tower is fading from the bottom up, and the moment those lowest bells brown over, the whole plant flips its job from flowering to seeding — and that seed-set is what kills it. Cut the main spike now, just above a leaf, and you do two surprising things at once: you trigger four or five smaller side spikes that flower through August, and you interrupt the death programme that makes a foxglove a strict two-year plant. It is the easiest cut in the early-June border and it can buy you a third year of flowering.

May 30, 2026

Pruning Broom After Flowering (Every Year)

Broom won't regrow from old wood, so it can never be cut back hard. A light trim right after flowering, repeated every year, is the only prune that works.

May 28, 2026

Pruning Choisya After Flowering

A light trim after the May flowers triggers a second flush of scented blooms in autumn. Here's how to prune choisya (Mexican orange) — not like a hedge.

May 28, 2026

Variegated Shrubs in Late May: Why the All-Green Shoot Will Take Over — and the Cut That Stops It

That single plain-green shoot pushing up through your variegated euonymus or elaeagnus isn't a one-off quirk — it's reversion, and because green leaves carry more chlorophyll than cream-and-gold ones, that shoot is already growing faster than everything around it. Leave it through June and it doesn't just sit there: it widens, branches, and shades out the variegated growth until the whole shrub is plain green by late summer. Here's how to spot it now, why snipping off the green leaves does nothing, and the single cut that actually stops it.

May 27, 2026

Pyracantha After Flowering: Why Shearing It Like a Hedge in June Steals Your Autumn Berries

The creamy froth on your firethorn is fading, the shrub looks shaggy, and the obvious move is to run the shears over it like a box hedge. Do that and you'll get a tidy green wall and almost no berries come October. Pyracantha fruits on short spurs off year-old wood, and the after-flowering cut is the one decision that turns this summer's soft new growth into next autumn's berry crop — or throws it away.

May 25, 2026

Euphorbia After Flowering: Do You Cut It Back?

Yes — but not just the tops. Follow each spent stem to the base and remove it whole, and never bare-armed: the milky sap blisters skin. Here's the right cut.

May 23, 2026

The Derby Day Box Trim: Why Early June Beats Late May (and Why You Want a Cloudy Day)

Reach for the shears on a sunny May afternoon and you'll see your boxwood scorched within a week. The old British rule of trimming on Derby Day (June 6 this year) isn't tradition for tradition's sake — it sidesteps late frosts, lets the spring flush harden, and gives the hedge a clean slate before high summer.

May 23, 2026

Hardy Geraniums After Their First Flush: The Late-May Chop That Buys You a Second Show

Around the last week of May your 'Johnson's Blue' and bigroot geraniums look like someone wrung them out. Faded petals, leaves going purple at the edges, the whole clump starting to flop sideways. This is the moment the experienced gardeners reach for shears, not the watering can — and a hard cut to five centimetres now buys a second flush of leaves in two weeks and a smaller second wave of flowers in late July.

May 21, 2026

Oriental poppies collapsed? Cut them to the ground

That yellow-brown collapse in late May isn't death — it's summer dormancy. Cut every stem to the ground for fresh foliage and a possible autumn reflush.

May 20, 2026

Tulip Foliage in Late May: The Eight-Week Window That Decides Whether Your Bulbs Come Back at All

Most gardeners treat tulips as annuals, and the reason almost always traces back to a single decision made in late May: cutting the leaves the moment the petals fall. Daffodils need six weeks of foliage. Tulips need eight, and the rules are stricter. Here's what the bulb is doing right now, what cutting too early actually costs you, and the late-May test that tells you the leaves are finally ready to go.

May 19, 2026

Mock Orange After Flowering: Cut to the New Shoot Below, Not the Bud Above

By the last week of May the first mock-orange cultivars are already dropping petals and the scent is at its peak. Most gardeners reach for the secateurs, trim back the flowered stems by a third 'to a bud', and feel they have done a tidy job. Next June, the bush flowers less. The cut was in the right week — but it was in the wrong place. Philadelphus rewards a different cut: not to a bud above, but to a strong new shoot already growing from below.

May 18, 2026

Weigela After Flowering: Why the One-in-Three Cut Beats the Hedge Trimmer Every Time

By the third week of May the first weigela cultivars have dropped their last trumpets and the second flush is still ten days away. Most gardeners notice the shrub is bigger than they remembered, reach for the shears, and trim it like a hedge. The flowering shrinks the following year. Every year. The shrub doesn't want a haircut — it wants a renewal cut, the one-in-three.

May 17, 2026

When to Prune Plums and Cherries (Silver Leaf)

Pruning plums and cherries in winter risks silver leaf disease. The safe window opens in mid-May and closes in August — here's exactly when and how to cut.

May 16, 2026

Clematis Montana After Flowering: The Late-May Shear That Saves Next Spring's Curtain

Most clematis advice argues over Group 2 versus Group 3, hard cuts versus light cuts, February versus March. But the biggest, fastest, most forgiving clematis of them all — Clematis montana — sits in Group 1, and its pruning window opens the moment the last petal falls in mid-May. Miss it and you'll be cutting off next spring's curtain with whatever you do later. Hit it right and you keep a montana flat against a four-metre wall for twenty years.

May 15, 2026

Ceanothus After May Flowering: Why Cutting Into Old Wood Kills Your California Lilac

Your Ceanothus is a wall of electric blue right now — and in two weeks, it'll be over. That's when most gardeners reach for the secateurs and make the one cut Ceanothus never forgives. Here's the line on every stem that separates a healthier shrub from a dead one, and how to find it before you cut.

May 13, 2026

Topping Broad Beans in Mid-May: The Five-Centimetre Pinch That Empties the Blackfly's Favourite Address

Most broad bean rows in May look perfect — bushy, dark-green, the first flower clusters wide open. Then one warm morning the top ten centimetres of every plant turns from green to glossy black overnight. That isn't bad luck and it isn't a weather event. It's the blackfly arriving on the only part of the plant they actually want, on a schedule you can pre-empt by reaching for it first with thumb and forefinger about ten days before they do.

May 12, 2026

Scarlet Lily Beetle in Mid-May: Why the Eggs Under the Leaves Matter More Than the Beetles On Top

The scarlet beetle climbing your lily stem is the easy part. Pick it off and you've removed one mouth. But every female you spot in mid-May has already laid two or three rows of orange eggs on the underside of the leaves below her — and those eggs hatch into the larvae that actually strip the plant. Here's the 30-second underside check that catches the next generation before it costs you your flowers, why neem and pyrethrum miss most of the damage, and the one companion plant that pulls the adults off your lilies entirely.

Hardening Off in Mid-May: Why Wind Kills More Seedlings Than the Last Frost

The Ice Saints have passed and the trays of basil, tomatoes and dahlias are stacked by the back door. Most guides will tell you to harden them off over ten days based on temperature. But the actual killer in a Northern European May isn't a -1°C night — it's the desiccation crash of an unhardened cuticle in the first six hours of unfiltered wind. Here's the wind-first protocol, the science behind it, and why a five-day schedule beats the textbook ten-day one if you get the first morning right.

Earthing Up Potatoes in Mid-May: The 23 cm Rule That Decides Your July Harvest

Most allotment guides tell you to earth up your potatoes 'when the shoots are about a hand high.' That single piece of folk-measurement is responsible for more lost yield than any pest in a Northern European May. Earth up too early and you smother the leaves the plant needs to fund its own tubers. Earth up too late and the lower stem has already lignified and won't throw new stolons. The window is narrower than most gardeners think, the trigger is 23 cm rather than the calendar, and the variety in your row decides whether a second hilling doubles your crop or just tidies the bed.

First-Year Strawberries in May: Why Pinching Off Every Flower Now Triples Next Summer's Harvest

Walk into any garden centre this week and you'll see the same scene: trays of strawberry plugs in full white flower, ready to plant out. Almost every gardener who buys them this May will plant them, water them, and wait for fruit. The ones who actually triple next year's crop do something that feels deeply wrong — they pinch off every flower this season, and they cut every runner the moment it appears. Here's why the first-year sacrifice is the single biggest yield decision in a strawberry bed, what 'pick flowers, not fruit' really means in a Northern European May, and how to read your existing patch this week to know whether it needs the same treatment or its opposite.

Bearded Iris in Mid-May: Why the Rhizome Wants Sun on Its Back, and the Fan-Trim Myth That Steals Next Year's Bloom

Almost every perennial in your border wants its roots cool, dark and mulched. The bearded iris is the exception that proves the rule — its rhizome should sit half out of the soil with sun on its back, and the moment you mulch it in a damp Northern European May, soft rot starts dissolving the crown from the inside out. Here's the mid-May routine that catches rhizome rot before it spreads, the staking trick that holds the bloom stem without snapping it, and why the fan-trim every magazine still recommends after flowering is quietly subtracting next year's flower count.

May 7, 2026

Wisteria After Flowering: Why May Is for Bending and Tying, Not Cutting

Most wisteria advice talks about August and February — the famous two-prune system. But there's a quieter window that opens the moment the racemes drop, and what you do with the new green whips between mid-May and the end of the month decides whether the plant builds flowering spurs or wastes the year on runaway leaders. The trick isn't cutting. It's bending.

May 6, 2026

Rhododendron Deadheading in May: Why You Should Snap, Not Snip — And How to Save Next May's Flowers

Your rhododendron has just dropped its blossoms and the spent trusses are still stuck to the bush like sticky brown badges. In the next two weeks the plant decides — based on what's right behind each truss — whether to make seed or set flower buds for next May. Snip with secateurs and you'll cut off the new growth that carries those buds. Pinch with thumb and forefinger and you redirect the plant's energy exactly where you want it.

Ice Saints 2026: Dates & When to Plant Out

The Ice Saints fall May 11–15 in 2026. Here are the exact dates, what the cold-snap folklore means, and how to tell when it's truly safe to plant out.

May 4, 2026

Daffodil Leaves in May: Why That Tidy Knot Steals Half of Next Year's Flowers

The April daffodils are done, the borders look messy, and the old gardening books tell you to knot, braid or rubber-band the foliage to keep things tidy. Don't. The six weeks after flowering are when the bulb does almost all of next year's work, and a single tied leaf reduces photosynthesis by roughly a third. RHS trials measured it. Here's what to do instead — and why a daffodil that goes blind almost always traces back to a May decision.

May 3, 2026

Peony Disbudding in May: The Pea-Sized Decision That Triples Your Bloom Size

Three buds on a peony stem don't give you three flowers — they give you three competing flowers that share the same pot of energy. Pinch off the side buds in the first week of May, while they're still pea-sized, and the terminal bud swells into a single dinner-plate bloom that lasts twice as long in the vase. Plus when to stake, why the ants stay, and how to harvest at the marshmallow stage.

May 2, 2026

Box Caterpillar in May: Why the First Webs Are Hiding Deep Inside Your Hedge

By the time the outside of a box hedge looks chewed, the caterpillars have already been feeding for two to three weeks — from the inside out. The first generation of Cydalima perspectalis hatches in May across most of northern Europe, and the only way to catch it before defoliation is to part the foliage and look for fine silk webbing on the inner branches. Here's exactly what to look for, when to spray, and why the wrong spray at the wrong stage does nothing.

May 1, 2026

Rose Suckers: Why Cutting Them Makes It Worse

Snipping rose suckers makes them multiply — they regrow from buds in the rootstock. The only fix is to scrape down and pull, not cut. Here's how to do it.

April 30, 2026

Pinching Out in May: The Thumbnail Decision That Doubles Your Sweet Peas, Dahlias and Tomato Harvest

Most gardeners look at a 10cm sweet pea, a knee-high dahlia and a leggy tomato in May and don't touch them — they're growing, why interfere? Because a thumbnail-sized nip at the growing tip in the first half of May overrides the plant's own internal command to grow tall and wakes up the dormant side shoots that decide your summer's flower count and tomato yield.

April 30, 2026

Tying In Climbing Roses for More Blooms

A climbing rose that only flowers at the top isn't the wrong variety — it's the cane angle. Tie canes horizontally in spring for blooms along every stem.

April 29, 2026

Lilac Pruning: The Two-Week Window That Decides Next May's Blooms

Your lilac flowered beautifully this May. Now you've got a narrow two-week window to prune before it quietly sets next year's flower buds — and most gardeners miss it. Here's what to cut, what to leave, and why a single late-June trim can wipe out an entire season of fragrance.

April 28, 2026

The Chelsea Chop: How a Late-May Haircut Doubles Your Summer Bloom Window

Most gardeners think pruning is what you do to plants in winter. But there's a counter-intuitive technique borrowed from Chelsea Flower Show week that can push your perennials' flowering season back by four to six weeks — and stop the late-summer flop that ruins so many borders.

April 17, 2026

Hydrangea Pruning in April: Why One Wrong Cut Can Cost You a Summer of Blooms

April is the month most gardeners reach for the secateurs and ruin their hydrangeas. The wood looks dead, the buds are swelling, the urge to tidy is real. But which cuts help and which ones quietly delete your summer show depends entirely on one thing: the type of hydrangea you own.

April 16, 2026

Cresco vs PictureThis: Which App Actually Helps You Care for Your Plants?

You snap a photo of your struggling rose bush. Both Cresco and PictureThis tell you it's a hybrid tea rose. But here's where the paths split: PictureThis stops at identification, while Cresco builds you a custom pruning schedule based on your local weather.

When to Prune Plants: A Month-by-Month Guide for Home Gardeners

Pruning at the wrong time can kill your favorite rose bush, prevent your fruit trees from producing, or leave your shrubs vulnerable to disease. Most gardeners approach pruning with guesswork, cutting whenever plants "look overgrown" without considering the plant's natural cycles or local climate patterns.

When to Prune Roses: A Complete Guide

Learn the exact best time to prune roses based on variety, climate, and season for healthy blooms year after year.
