How To Grow Raspberries

A raspberry – delicious, sweet, tangy, and sometimes even a little sharp. This guide covers both summer and autumn raspberry varieties.

Growing raspberries is not difficult, as once established they are relatively easy to take care of, especially compared to salad crops or other vegetables.

See raspberry varieties or ideas for where to buy seeds and plants.



Planting

  • October – March
  • Planting depth: Roots 5 -10 cm below surface
  • Planting spacing: Canes 50 cm apart, 1.5 m between rows

Harvesting:

  • May – September (if growing both summer and autumn raspberry varieties)
  • Eat fresh, make jams, or freeze

Planting raspberries is very similar whether you want to grow summer raspberry canes or autumn raspberry canes. The pruning for each type is different, but the initial preparation is the same.

When to plant raspberries? Late autumn or early spring is the ideal time to plant – it is a job often done in cold weather. This is good for the raspberry canes as they are dormant during the winter months, and having them in the soil before the growing season starts will give them the maximum time to establish themselves.

It is important to plant the canes with their roots horizontal along the ground, rather than down into the earth, and not too deep, about 5 to 10 centimetres is all they need. A successful planting will lead to the canes establishing themselves, developing their root systems, and throwing up many new canes in future years. Mixing in large amounts of well rotted compost will improve the health of the canes and the size of the fruit.

Five canes per pot is the usual number when purchased from a garden centre, and this is sufficient for one 2 m line of raspberries.

I suggest choosing different types of raspberry bush for each line of raspberries you have, so that you can enjoy their different flavours, and because each variety fruits at different times, making it possible to have a continuous supply of raspberries from early summer to autumn.

To complete the preparation, at both ends of each line of raspberries, I hammered into the ground a 2.2 metre post (about 50cm into the soil), and strung wire between between the posts at around 45 centimetre intervals. I tied the canes to the wires for protection against wind sway during summer growth.

Once planted, caring for raspberries is quite a simple process. The humble raspberry grows very well in Scotland, a country that is famous for raspberries and is the source of many raspberry canes sold in garden centres. From this, it is perhaps not surprising that they like warm, but not very hot weather in the summer, and they do especially well with a good amount of rain (or watering).

Establishing a watering regime is the best way to care for raspberries and maximise your harvest. Raspberry roots are close to the surface which means that in dry weather the canes can quickly dry out. From experience this is something to regret, as canes can ‘go over’ before they have produced a plentiful crop of fruit due to insufficient watering.

A good solution is a thick mulch early spring, that both feeds and protects the roots from drying out. The soil my raspberry bushes stand on has excellent drainage, in fact almost too good, meaning that it is impossible to over water. Given this, I find that throughout the summer in dry periods I need to give the raspberry canes a really good watering at least once a week.

With good luck and good weather (plus netting against birds) it is easy to achieve a good harvest. If you can, try and sample some raspberries of any friends or relatives, and then purchase canes of the same type – or even better ask them at the end of summer whether they have any new canes they can spare.
