This year I’m planning to make full use of the greenhouse by focusing on fruit, especially the kinds that really benefit from warmth, shelter, and a longer growing season. There is something very satisfying about stepping inside and picking something sweet and juicy straight from the plant, and under a Hampton Greenhouse you can grow far more than many people realise.
Grapevines are right at the top of the list. They thrive in heat and bright light, and once settled in they can be wonderfully productive. Trained along wires or across the roof, they not only produce generous bunches of fruit but also create a soft canopy of leaves that helps take the edge off strong summer sun.
Peaches and nectarines are another priority because they are so much more reliable under cover. Outdoors their blossom is easily damaged by cold spring rain, but in a greenhouse they can set fruit consistently. The bonus is the early display of soft pink flowers, which makes the whole space feel alive long before summer arrives. Apricots fall into the same category. They often struggle outside, yet inside they can crop beautifully and reward you with intensely flavoured fruit.
Citrus fruits are hard to resist because they brings a completely different mood to the greenhouse, especially during our long winters. Lemons, kumquats, and small oranges grow happily in containers and offer glossy evergreen leaves, highly scented blossom, and colourful fruit at the same time. With a little winter protection they can provide harvests when the garden outside is bare, which feels like a real luxury.
Soft fruits also do extremely well under glass, particularly if you want crops earlier than usual. Raspberries grown in deep pots can fruit weeks ahead of those in the open garden, and autumn-fruiting varieties are especially straightforward to manage. Blueberries are another excellent choice as long as they have acidic compost. They bring delicate flowers in spring, fruit in summer, and fiery foliage in autumn, all from a single plant. Gooseberries and currants can also be grown in containers or trained neatly along the sides, producing generous crops without the usual battle with birds.
Once you start thinking along these lines, more unusual possibilities come into view. Pineapples grown from the tops of shop-bought fruit are slow but fascinating, eventually possibly producing a single striking fruit. Bananas add a lush, tropical feel with their huge leaves, even if they never quite ripen a crop. Passionfruit vines can scramble along the roof, covering it in intricate flowers followed by distinctive oval fruits if conditions suit them.
Growing fruit in a greenhouse does mean taking a slightly more active role. Pollination may need a gentle helping hand with a soft brush, watering must be regular because containers dry out quickly, and good ventilation is essential to keep plants healthy. None of this feels onerous though. It is simply part of caring for a productive space.
One of the greatest pleasures is how a greenhouse stretches the seasons. You can move from early berries to summer stone fruits, then grapes and figs as autumn approaches, and finally citrus through the winter months. The space becomes an engine of continuity, providing fresh produce long after the garden outside has slowed down.
Above all, a fruit-filled greenhouse offers atmosphere as well as harvests. There is scent in the air, colour at every level, and the quiet satisfaction of watching fruit swell over time. Picking something perfectly ripe and sun warmed straight from the plant is one of gardening’s simplest and greatest pleasures.
Even a small collection of plants can provide bowls of fruit, the occasional jar of jam, and a sense of abundance that feels completely out of proportion to the space they occupy. So if you are wondering what to grow under your Hampton glass, fruit is a wonderful place to start.
