'How To' Grow Raspberries

When to Plant Raspberries

Raspberries are planted any time between November and March, provided the soil is not frozen or waterlogged. They are normally sold as dormant canes.

What Raspberry Variety?

  • There are two types of raspberry plants:

  • Summer-fruiting raspberries - these will fruit between June and early August depending on specific varieties. For the earliest raspberries 'Glen Moy' is a good variety and for delicious flavour you can't beat 'Glen Fyne'!

  • Autumn-fruiting raspberries - these will fruit between August and October and are ideal for growing in containers on the patio as they don't need supporting. They are also great for beginner gardeners as the pruning is very simple. One of the most reliable varieties is 'Autumn Treasure', although for something more unusual try growing yellow raspberries such as 'All gold'.

Primocanes and Floricanes - What's the Difference?

Don't let these terms confuse you. Primocane varieties produce flowers and fruit on stems grown in the same year. Most Autumn fruiting varieties are primocanes producing fruit in their first year of growth. Summer fruiting varieties are usually Floricane raspberries which have stems that grow for one year before bearing fruit and flowers. Because floricanes and primocanes produce crops on different aged stems, they require slightly different pruning techniques. Read on to find out how to prune raspberries.

Where to Plant Raspberries

When planting your strawberries give them plenty of space for better cropping and easy access. For growing in the ground, plant strawberries 45cm (18") apart and in rows spaced 75cm (30") apart. Use a trowel to dig a hole big enough to accommodate the roots of the plant. If planting strawberry runners spread the roots out in the hole and make sure the crown of the plant is resting at soil level. Pot-grown plants should be planted so the top of the compost is level with the soil surface. Planting too deeply can cause the strawberry plants to rot, and planting with the crown too high above the soil surface can cause the plants to dry out and die. Firm the plants in well and water thoroughly.

Growing Raspberries in the Garden

Once you've chosen your site, simply break up the soil with a garden fork and dig in some organic matter such as compost (old or new), well rotted manure or recycled green waste. Create a framework of posts about 1.8m (6ft) high and stretch wires horizontally across them. Set the wires about 60cm (2ft) apart. If you have space for more than one row, make sure the rows are 1.8m (6ft) apart. For summer-fruiting raspberries, plant each cane about 40cm apart and for autumn-fruiting raspberries plant each cane about 60cm apart. When planting raspberries, place them at a depth of about 8cm (3in) and gently firm them in and water them well. Once planted, cut the canes to 25cm from the ground to encourage lots of basal shoots.

Growing Raspberries in Containers

Raspberries can successfully be grown in containers on the patio as long as the container is of a reasonable size about 60cm (24in) diameter. Fill your container with a soil based compost such as John Innes No. 3 as this will add stability to your container and won't dry out as quickly as multi-purpose compost . Plant 6 raspberry canes around the edge of the container and gently firm them in and water them. As with all patio plants make sure the compost doesn't dry out and feed your raspberries regularly with a high potash fertiliser throughout the growing season to encourage lots of delicious fruit. After 3 years it's best to plant your container raspberries in the ground.

Caring for your Raspberries

Raspberries need feeding in the spring to maintain a good crop throughout the season. Mulch around the canes with well rotted manure (take care not to bury the canes) or apply a balanced fertiliser and then mulch with compost to help keep the roots moist in dry weather. As well as feeding raspberries it's important to water them during dry weather for the best cropping. You will find that raspberries produce 'suckers' along their root system so new canes may pop up a fair distance from the main plant. Any that are more than 22cm (9in) from the main row should be dug up and pulled out (don't worry severing them won't harm the parent plant). When the plants start to set fruit it's advisable to cover them with netting to prevent the birds eating your delicious crop!

Pruning Raspberries

  • Knowing when to prune raspberries can seem complicated but it is really very simple! All you need is a good pair of secateurs and some gardening gloves to protect against thorns.

  • Pruning autumn-fruiting raspberries these are the simplest to prune. In late winter (February) prune all the canes to ground level before growth commences. The plants will fruit on new growth.

  • Pruning summer-fruiting raspberries these produce fruit on one year old canes. In autumn cut all canes down to soil level that bore fruit during the summer. To help with pruning summer raspberries, it may be worth marking the fruiting canes during the summer so you can distinguish between these and the new season's canes (new season's canes are lush and green). Aim to tie in 6-8 of the strongest new canes and remove the rest. The new canes should be spaced out about 10cm (4in) apart on their support to allow each cane as much light and air as possible.

Harvesting your Raspberries

You can tell when raspberries are ready to harvest as they will easily come off the plant when gently pulled. Once harvested, raspberries don't keep for long so try freezing some for later use by spreading them on a baking tray and placing in the freezer. The frozen raspberries can then be moved into freezer bags.
