Want to grow fruit but aren’t sure if you have the space? Grow in containers! Learn how to grow three types of berries that you can get into pots before winter’s chill really sets in: raspberries, currants, and blueberries. Nutritious, delicious and packed full of goodness!

Why grow fruit in pots? Fruits grown in containers are easier to protect from birds and other critters, more disease-resistant, and easy to harvest. Potted berries can be picked when ripe by placing their container on a bed sheet or tarp and shaking the pot. Plus, you can grow fruit like blueberries even if your garden doesn’t have the right soil!

We will demonstrates the best potting mix to use for fruit plus more tips for growing these irresistible crops in containers.

Growing Raspberries in Containers

Raspberries are always going to be a winner. Like all berries, they are absolutely loaded
with vitamins and antioxidants—all the good stuff. They are highly versatile in the kitchen and, given what they cost in the grocery store, growing raspberries will give you plenty of bang for
your buck! Try a smaller variety perfect for container growing, under 3-feet-tall; unlike traditional varieties with longer canes, there’s no need for supports. Plant in a  wide container that holds about 8 gallons of potting mix to provide plenty of space for both the roots and the canes to spread out.

Raspberries prefer a slightly acidic soil, which helps prevent nutrient deficiencies. So while the bulk of my potting mix can just be a general-purpose mix, add in some peat-free potting mix for acid-loving plants, also sold as ericaceous, or rhododendron or azalea mix. We want a ratio of roughly 80% general-purpose potting mix to 20% acid mix. The acidic mix is soil-
based, which will add extra weight and stability to the container. Soil holds onto moisture a bit
better too, so it shouldn’t dry out as quickly.

Planting raspberries couldn’t be simpler. Remove them from their pots then pick away
at the roots if they have been tightly coiled up against the edge of the pots. Don’t be shy about
this stage as it will help the roots to find their way out into the fresh potting mix that little bit faster. Set them in at the same depth, firm them in, then give everything a thorough water to settle the mix.

If you’re planting a bare-root plant, you can tell where the previous soil level was by the dark mark on the canes;  make sure all of the darker area is covered. Finishing off with a natural mulch not only gives a really smart finish, it will also help to keep the roots cooler in hot weather. And organic mulches will naturally rot down over time. Something like a finer wood chip mulch is perfect.

Growing Currants in Containers

Currants are superb in containers too. Both red and white currants can be trained into
compact cordons and fans, or grown as standard bushes. What patio, terrace or balcony
wouldn’t look better for having one of these! Blackcurrants are also good to try but as this
is the most vigorous of the currants and can’t be trained, choose a more compact variety. 

Redcurrant are certainly the most popular. Use a soil-based potting mix together with a
container that’s at least 18 inches in diameter. Plant it just like the raspberries (above), teasing out the roots then settling it in at the same level it was at before. Finish off with a mulch of bark chippings.

Currants grow best in a sheltered, sunny spot, but they’ll also tolerate a little dappled
shade. During the growing season, it will need watering regularly to keep it from drying out, but the bigger danger is getting too wet from heavy rains and the roots rotting as a result, so make sure excess water can drain out by simply raising the container up onto pot feet or pebbles. And if you’re somewhere that gets very cold winters, move them undercover or
insulate the containers with something like bubble wrap to stop the roots from freezing
too hard.

Feeding currants couldn’t be easier. Apply a liquid tomato feed every few weeks during the growing season or tickle in a slow-release balanced fertilizer at the start of spring.

Growing Blueberries in Containers

Beeeautiful blueberries! Who doesn’t love snaffling them straight off the bush. But if they do make it into the kitchen, remember they can also be frozen just as they are—no prep needed. And that applies to all berries and currants. They’re such great freezer staples and can be on hand at any time of the year to bring a little burst of sweet joy whenever needed.

Blueberries need a really acidic soil to thrive, with a pH somewhere between 4.0 and
5.5. Get this right and offer them a sunny spot and they’ll thrive. So for blueberries, you’ll
once again need an acidic or ericaceous mix. Eek it out by adding, say, 30-40% garden compost to the mix, or even some wood chips.

After the first summer crop, you can pot your blueberries into a larger container in the spring;
freshen up the top layer of soil by just scraping it out and replacing with fresh. And then finish up with more wood chip mulch.

To keep the soil acidic and plants happy, it’s best to water blueberries using rainwater– and the same goes for all of our berry fruits. Once growth reaches full speed in spring, commence feeding every three weeks or so using an acid-loving plant feed.

Birds are notorious for stealing ripening berries! The simplest way to keep them off is to cover plants with netting. But don’t just drape the netting straight onto the plant. Instead, create a framework to sit the netting on. That way the birds won’t be able to peck through it, and there’s less risk of them getting caught up in it too. Something like a cane teepee works well, for example, or you could create more of a box framework if you have quite a few potted fruits to protect by attaching horizontal canes to uprights, and then draping the netting over that.
