No garden but a craving for your own berries? No problem. A balcony, terrace or even a sunny windowsill is enough to grow strawberries, blueberries, raspberries and many other berries in pots. The fresh, sun-warm berry straight from your own balcony beats any bought one, and growing in a container is easier than many think.
The pot even brings a decisive advantage: full control over the substrate. Whoever sits on heavy, chalky soil in the bed can hardly grow blueberries. In a pot you simply fill in the right, acidic substrate and it works. This article shows you which berries suit the pot and what matters when watering, feeding and overwintering.
Which berries succeed in a pot
The good news first: there is hardly a berry that could not be grown in a container. From the classic balcony strawberry to the columnar blackberry almost everything is possible, you just have to match pot size and demands.
The best berries for pots and balconies
- Strawberries, the beginner berry
Strawberries are the most grateful balcony fruit. They thrive in pots, boxes and hanging baskets, bear in the first year and need little space. Everbearing varieties supply all summer.
- Blueberries in an acidic pot
Blueberries are made for the container, because they need acidic soil that you easily provide in a pot. In rhododendron or bog-bed compost they often thrive better than in most garden soils.
- Raspberries and blackberries in a pot
Raspberries too grow in a large pot, best in compact or columnar varieties. Thornless columnar blackberries stay handy and need only a stake as support.
- Currant and gooseberry as standards
Grown as a high standard in a pot, currant and gooseberry are decorative and productive at once. They are easy-care and last for years.
Choose the pot generously. As a rule of thumb: rather too large than too small. A larger volume of soil buffers temperature and moisture better, the plant grows more stably and you have to water less often. For a blueberry it should be at least thirty, better forty litres, for strawberries much less suffices. Drainage holes and a drainage layer are always important, because waterlogging is the most common killer of potted plants.
Lime-free watering is the key
The most important and most often overlooked point with potted berries is the watering water. Many berries, above all the blueberry, dislike lime. Tap water is hard in large parts of the country, that is chalky, and raises the pH in the pot a little with each watering. After one or two years the acidic substrate is neutralised, the blueberry gets yellow leaves and sulks.
The solution is simple: water lime-sensitive berries with rainwater. A rain barrel at the downpipe is the best investment for any balcony gardener. Where that is not possible, you can acidify tap water with an additive, but rainwater is the most natural and simplest way. Yellow leaves between green veins, the so-called chlorosis, are the classic warning sign of too much lime.
On substrate the rule is: blueberries, cowberries and cranberries need acidic special compost, often sold as bog-bed or rhododendron soil. How to create the right acidic site for berries permanently is covered in detail in Blueberries, acidic soil and container. Strawberries, raspberries and currants, by contrast, are less fussy and get by with good, humus-rich container compost.
Watering and feeding in the pot
A pot dries out much faster than garden soil, especially on hot summer days and in full sun. Potted berries therefore need regular, attentive watering. Check the soil with your finger: if the top layer feels dry, water. On hot days that can be necessary daily, a larger pot forgives more here than a small one.
Because the nutrients in the limited pot volume are quickly used up, potted berries need more attention when feeding than bed plants. An organic berry fertiliser in spring and a follow-up feed in early summer supply them over the season. But do not overdo it, because too much fertiliser harms more than too little. How to supply berries correctly and moderately explains Feeding berries correctly.
Winter is the biggest hurdle
What many underestimate: the real weak point of the potted berry is not summer but winter. In garden soil the roots are deep and frost-protected. In a pot, by contrast, the root ball stands practically free in the air and freezes through completely in hard frost. Some plants do not survive that, although they would be perfectly hardy in the bed.
Move the pot to the house wall
Place the containers close to a sheltered house wall in winter. It stores warmth and softens the sharpest frosts.
Insulate from the cold ground
Stand the pots on a polystyrene board or wooden battens so the cold does not draw into the ball from below. Direct contact with the ice-cold ground is especially harmful.
Wrap the pot
Wrap the pot in fleece, jute or bubble wrap in severe frost. The point is not to keep the plant warm but to protect the root ball from freezing through.
Water on frost-free days
Even in winter the ball must not dry out completely. Water sparingly on frost-free days, especially evergreen berries like some cowberries keep transpiring.
Frost-hardy berries like currant and blueberry survive winter outdoors with this protection without trouble. They even need the cold as vernalisation to bloom next year and by no means belong in the warm home. Only the pot itself needs protection, not the plant.
Large pot, lime-free rainwater, acidic substrate for blueberries and root protection in winter. Whoever heeds these four things harvests on the balcony as well as in the garden.
The core rule for potted berries
Frequently asked questions
Which berries can you grow in a container?
Almost all. Strawberries are ideal for beginners, blueberries often thrive better in an acidic pot than in the bed, plus raspberries and blackberries in columnar varieties and currant and gooseberry as standards. A sufficiently large pot with drainage holes is important.
Why does my potted blueberry get yellow leaves?
Usually from too much lime. Blueberries need acidic soil and soft water. Hard tap water raises the pH and leads to chlorosis, the yellow leaves with green veins. Water with rainwater and use acidic bog-bed or rhododendron compost.
How often do you have to water potted berries?
Clearly more often than bed plants, because pots dry out fast. Check the top soil layer with your finger and water as soon as it is dry. On hot summer days daily watering can be necessary, a larger pot needs water less often.
Do you have to bring potted berries indoors in winter?
No, frost-hardy berries like currant and blueberry stay outside and even need the cold. Only the pot needs protecting: move it to the house wall, insulate it from the ground and wrap it in severe frost so the root ball does not freeze through.
What pot size do berries need?
As large as possible. A larger soil volume buffers warmth and moisture better. For blueberries at least thirty to forty litres, for raspberries similar, for strawberries small pots or boxes suffice. Drainage holes and drainage are always a must.
