How To Tell What Facing Garden You Have | Noon Sun Test

How To Tell Which Way Your Garden Faces

The fast path at home is to check light at noon. Stand by the back door around local midday on clear days; repeat once. Face the garden. If the rear wall behind you glows with direct light, the plot leans south. If that wall sits in shade and the far fence looks bright, the plot leans north. Morning light with cool evenings points east. Late, warm light after work points west.

Compass apps also work. Set the app to True North. Hold the phone dead flat by the back door and sight the line into the plot. A bearing near 180° means south; near 0° means north; near 90° means east; near 270° means west.

You can double check with a stick test. Push a straight stick in the soil where you can see the shadow. Mark the tip of the shadow at the top of each hour. Join the points. The shortest mark lands near noon and points north in the northern hemisphere. The line from that point through the stick shows south.

Garden Aspect At A Glance

Aspect	Midday Sun Pattern	Typical Feel & Plant Notes
South	Longest, strongest sun near noon	Warm, dry; suit herbs, vines, heat-loving veg
North	Little to none at noon	Cool, even light; suit ferns, hostas, hydrangeas
East	Bright morning; shade after lunch	Gentle light; suit camellias, salads, spring bloomers
West	Shade in morning; warm light late	Hot evenings; suit roses, dahlias, beans, squash

Quick Clues From Your Home And Plot

Read the rear wall. Brick or render that feels hot to the touch in early afternoon hints at a south bias. Moss growth and slow drying paint suggest a cool face, common on north walls.

Track morning and evening. Does breakfast light pour across the patio then fade by lunch? That pattern matches an east facing plot. Do you get shade at breakfast yet long, warm rays after 4 pm? That points to a west facing plot.

Watch fences and neighbours. Tall conifers, sheds, or townhouses can steal sun. A south facing plan can still feel cool if a high block sits to the south. Make notes on a simple sketch so you don’t miss a blind spot.

Season, Obstacles, And Microclimates

Sun angles swing through the year. Winter sun rides low and hides behind nearby roofs. Summer sun climbs high and clears many obstacles. That is why a winter view can look gloomy while July feels bright.

Walls and slopes change heat and light. A pale wall bounces light back into beds. A dark wall stores heat by day and releases it at night. A slope that faces south dries faster and feels warmer. A dip traps cold air and frost. These small shifts all add up. Learn more about aspect and small heat pockets in the RHS microclimates guide.

What Counts As Full Sun Or Shade?

Full sun means around six or more hours of direct light on a clear day during the growing season. Partial shade sits near three to six hours. Dappled shade is broken light under open trees. Deep shade is little or no direct light. Log the hours and you’ll size up the plot with confidence.

Planting Moves Once You Know Your Aspect

South facing beds suit heat lovers. Think rosemary, thyme, lavender, salvias, sunflowers, tomatoes, peppers, aubergines, and grapes. Use mulch and steady water to keep roots happy. Lift pots a touch so drainage stays sharp.

North facing beds shine with shade stars. Hostas, ferns, heuchera, brunnera, astrantia, hydrangea, and many spring bulbs handle low light. Brighten views with white flowers and silver foliage. Improve soil with leaf mold to hold moisture.

East facing beds enjoy gentle morning rays and a cooler afternoon. Camellias, daphne, azaleas, lettuce, peas, spinach, and many herbs thrive in that rhythm. Shelter early blooms from late frost.

West facing beds catch warm evening sun. Roses, geraniums, echinacea, dahlias, beans, squash, and pumpkins enjoy the heat. In dry spells, water in the morning so foliage dries by night.

Hardscape choices can help. Pale gravel, mirrors, or a light fence reflect light into dark corners. Lattice panels soften wind while letting light pass. Swap tall hedges on the south edge for lower planting to avoid shade creep.

Ways To Check Your Garden Facing

When you use a compass or app, set it to True North. If your tool needs a correction, look up your town on the NOAA magnetic declination page and apply the value.

Method	What You Need	Reliability
Noon wall check	Clear day, quick look	Good first read; repeat on two days
Compass app set to True North	Phone, flat hold, declination set	High when calibrated and kept level
Shadow stick plot	Stick, pebbles, hourly marks	High; shows north line on site
Sun path website	Location and date	High; great for patios and sheds
Satellite view	Map app and house outline	Good; cross-check with a real visit

Common Mistakes When Judging Aspect

Relying on one cloudy day. A grey day can fool the eye. Take notes on two or three clear days across a month.

Trusting only winter or only summer. The feel in January is not the feel in June. A quick shade map each season pays off.

Ignoring buildings nearby. A single tall tree or a new loft conversion can flip a bed from full sun to shade.

Using a compass without true north set. If your app points to magnetic north, your reading can drift by a few degrees. Check settings.

Forgetting taller plants you’ll add. A new pergola, apple tree, or arch can shift light. Draw likely shade on your plan before you plant.

Simple Weekend Plan To Map Sun And Shade

Saturday morning: sketch the plot. Draw house, fences, trees, shed, and the path of the main bed lines. Print a copy of the map from your phone if that helps.

Saturday noon: stand at the back door and take a compass reading to the far boundary. Write the bearing on your sketch. Note which walls are lit.

Saturday late afternoon: note any hot spots and glare on patios. Mark wind gusts and cool draughts between buildings.

Sunday morning: repeat quick checks. Mark where light first hits and how long it stays on main beds. Time the first and last direct rays. Add photos to a folder with labels like “noon patio” or “5 pm veg bed” to track the pattern.

Sunday wrap-up: label the aspect for each main zone. Example stamps: “front bed: east facing, 4 hours sun”; “rear left: north west corner, bright shade”. Keep the sheet with your seed packets or clipped inside the shed door.

Extra Clues For Tricky Plots

East And West: Daily Rhythm Tips

Pick a breakfast chair and an after-work chair. If breakfast feels bright and plates cast sharp shadows, you likely face east. If suppers glow and sunsets warm the bricks, you likely face west. Use that rhythm to place seating, a reading nook, or a grill.

Balcony, Courtyard, And Townhouse Quirks

High walls can behave like canyons. Light bounces between surfaces and can push brightness deeper than you’d think. Gloss paint on a fence reflects more than matte. Glass balustrades pass light; solid panels block it. In a tight court, even a south face can read cool at ground level while a terrace up on the first floor basks.

Mixed Aspect? Zone It

Many plots tilt one way at the house and another at the far end. Label zones instead of the whole plot with a single tag. You might have a south facing patio, an east facing veg bed along the fence, and a north west corner by the shed. Plant each zone to its own light story and you’ll get better results.

Water And Wind Notes

South and west beds shed water faster after hot afternoons. Drip lines save time and keep leaves dry. North and east beds stay moist longer, which helps lush foliage but can invite slugs. Create airflow with spacing. A small gap under solid fences lets cool air drain away on still nights and reduces frost pockets.

Planting Pitfalls By Aspect

Camellias burn in hot afternoon sun right after a cold night, so an east site suits them better. Lettuce bolts early on a hard south wall; grow it in the east or in part shade. Peppers sulk in deep shade and sit still; move them to the warmest spot you have. Fern crowns rot in waterlogged shade; add grit and raise the crown a touch.

Home Tools That Help

Use your phone’s map app in satellite view. Note the roof ridge line. Most houses in a street run the same way. Drop a pin at your home and check the little compass in the corner. That angle gives a clue even on cloudy days. A cheap analog compass also works. Keep it away from cars, fences, and speakers when you read it.

Handy Notes You Can Keep

Aspect describes the direction the garden faces relative to the house, not just one bed. Large plots can have more than one aspect.

Sun path tools on the web let you check angles by date. A quick look helps when planning a patio or greenhouse site.

If in doubt, plant in pots first. You can move containers through the season and learn where each plant smiles.
