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
Raspberries like fertile, well drained soil in a sunny spot. They will tolerate shading but you’re unlikely to get as much fruit as raspberries growing in full sun. Summer-fruiting raspberries will need supporting by a fence, wall or other type of framework as they can grow to 1.5m tall. Autumn-fruiting raspberries are normally fine without a support.
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.
