Sunlight is the ingredient that makes fruit sweet. A fruit tree in full sun produces fruit that is sweeter, better coloured and earlier to ripen than the same variety in shade, because sunlight drives the photosynthesis that makes sugar, and sugar is flavour. That is why every fruit book starts with the same advice — plant fruit in the sunniest spot you have — and why a fruit tree planted in the shade of a house or a large tree is a disappointment, however well you water and feed it.
Full sun, in gardening terms, means at least six hours of direct sun a day, and for most fruit, eight hours is better. The sun needs to fall on the leaves and the fruit, not just on the garden in general: a tree planted against a north-facing wall is in shade even if the garden is sunny, and a tree under a larger tree is in shade even if the sky is bright. Morning sun is particularly valuable, because it dries the dew off the leaves quickly and reduces fungal disease, while afternoon sun is the hottest and ripens the fruit.
Not all fruit needs the same amount of sun, and the differences matter when you are placing plants in a garden that is not uniformly sunny. Tree fruit and grapes need the most sun; berries tolerate a little shade; and a few fruits — notably currants and gooseberries — will crop in partial shade, though they crop better in sun. Knowing which fruit goes where is how you use every sunny corner and every partly shaded one. If you are unsure about a variety, a spray, or a diagnosis, check your local extension service — its advice is matched to your climate and soil.
Full sun fruit: apples, peaches, grapes and citrus
Apples, pears, peaches, plums, cherries, figs, grapes and citrus all need full sun — six to eight hours of direct sun a day, and more if they can get it. Peaches and figs are the most sun-hungry of all: a peach in less than full sun will flower poorly, set little fruit, and the fruit it does set will be small and sour. Grapes need sun on the bunches themselves, not just on the leaves, which is why grape vines are trained to expose the fruit to the sun. Citrus needs full sun to fruit and to ripen, and a lemon tree in a shady corner will grow leaves and little else. Apples and pears are a little more forgiving than peaches or figs, and they will crop in six hours of sun, but they crop better in eight. If you have one truly sunny spot, give it to the peach, the fig or the grape, and put the apple where the sun is good but not perfect. Our growing guides for apples and figs cover the sun needs of each fruit.
Berries and partial shade: what tolerates less sun
Berries are more shade-tolerant than tree fruit, and this is useful in a garden with mixed light. Raspberries and blackberries crop well in full sun but will crop in partial shade, though the fruit will be later and less sweet. Strawberries need full sun for the sweetest fruit, but they will crop in partial shade, and in a hot climate a little afternoon shade can stop the berries scorching. Blueberries need full sun for the best crop, but they tolerate light shade. Currants and gooseberries are the most shade-tolerant fruit of all: they will crop in partial shade, and they are the fruit to plant on the north side of a fence or in the dappled shade of a tree. That tolerance is relative — a currant in deep shade will still disappoint — but it makes currants and gooseberries the right choice for the least sunny corner of the fruit garden. The sunlight calculator can help you work out how much sun a spot in your garden actually gets through the day.
Sun, shade and the ripening of fruit
Sun does more than feed the plant: it ripens the fruit directly. The sun warms the fruit, and warm fruit ripens faster and tastes sweeter than cool fruit, which is why the fruit on the sunny side of a tree ripens first and the fruit inside the canopy ripens last. Pruning for an open canopy is really a sunlight job: it lets the sun reach the fruit in the middle of the tree, not just the fruit on the outside. Reflecting heat helps too: a peach or a fig trained against a south-facing wall benefits from the heat the wall stores during the day and releases at night, and the fruit ripens earlier and sweeter than the same variety in the open. A light-coloured wall reflects more light than a dark one, and a gravel mulch reflects light up into the canopy. In a cool climate, that reflected heat can be the difference between a fig that ripens and a fig that never does.
Too much sun: scorch, sunburn and hot climates
In a hot climate, too much sun is a real problem. Fruit can scorch on the sunny side, leaves can burn, and the soil can dry out faster than you can water it. Apples can develop sunburn — a bleached, papery patch on the sunny side — and strawberries can scorch in a heatwave. The answer is not to plant fruit in shade but to manage the heat: mulch thickly to keep the soil cool and moist, water deeply, and give the most vulnerable fruit a little afternoon shade, either from a taller plant to the west or from a shade cloth in the hottest weeks. Whitewash on the trunk of a young tree prevents sunscald, the bark damage caused by winter sun heating the bark by day and frost freezing it by night. In a hot climate, a little afternoon shade is a benefit, not a loss — the fruit still gets its six hours of morning sun, and it escapes the fiercest heat of the day.
Making the most of the sun you have
Walk your garden through the day, in each season, and note where the sun falls and for how long — a spot that is sunny in June may be shaded in March, when the fruit is flowering. Plant the sun-hungry fruit where the sun is longest, and the shade-tolerant fruit where it is shorter. Prune trees so the sun reaches into the canopy, and do not let a hedge or a fence grow up to shade a fruit bed. If a tree is shaded by a larger tree, consider removing the larger tree or moving the fruit — a fruit tree in shade is a tree that will never repay the space it takes. For containers, the advantage is that you can move the pot to follow the sun through the season, and a pot on a sunny patio will out-produce the same plant in a shady border. And if your garden is genuinely shady, be honest about it: grow currants, gooseberries and raspberries, which tolerate shade, rather than peaches and figs, which will not.
Sunlight through the seasons
The sun a fruit plant needs changes through the year. In spring, sun on the blossom matters, because bees work in sun and a blossom in shade is a blossom the bees may miss. In summer, sun on the fruit matters, because it ripens and sweetens the crop. In autumn, sun on the wood matters, because it helps the new growth harden before winter. In winter, sun on the bark of a young tree can cause sunscald, and a whitewash or a guard prevents it. A deciduous tree loses its leaves in winter, so a fruit tree planted where it is shaded by a deciduous tree in summer but sunny in winter is a poor choice — the shade falls exactly when the fruit needs the sun. Evergreen shade is worse, because it shades the fruit all year. When you choose a spot, think about where the sun will be in June, when the fruit is swelling, not where it is in January.
Frequently asked questions
How many hours of sun does a fruit tree need?
At least six hours of direct sun a day, and eight is better. Peaches, figs, grapes and citrus are the most sun-hungry; apples and pears will crop in six hours but do better in eight.
What fruit grows in partial shade?
Currants and gooseberries are the most shade-tolerant fruit, followed by raspberries and blackberries. Strawberries and blueberries will crop in light shade but taste better in full sun.
Why is the fruit on the sunny side of my tree riper?
Sun warms the fruit directly and drives the sugar production that ripens it. The fruit inside a dense canopy ripens later, which is why pruning for an open canopy matters.
Can fruit get too much sun?
Yes, in a hot climate. Fruit can scorch, leaves can burn, and the soil dries out. Mulch thickly, water deeply, and give vulnerable fruit a little afternoon shade in the hottest weeks.
Will a fruit tree grow in the shade of a house?
It will grow, but it will fruit poorly or not at all. Fruit needs direct sun on its leaves and fruit, and a tree against a north-facing wall or under a larger tree is in shade even if the garden is sunny.
Sunlight is free, and it is the most powerful tool in the fruit garden. Give the sun-hungry fruit the sunniest spot, give the shade-tolerant fruit the rest, prune so the sun reaches the fruit, and let the wall and the mulch do their work.
