How to Grow Raspberries

Raspberries grow easily and are available in both autumn and summer fruiting varieties. You can get plenty of fruits from mid-summer to mid-autumn with just a few plants. You can make delicious sauces, jams and cooked desserts by freezing them well.  

Growing 

What’s the best site for Raspberries?

Here are some things that we suggest you need to keep in mind while choosing an appropriate site for growing the fruit: 

  • Choose fertile, moisture-retentive and slightly acidic soil.
  • Ensure that the site is weed-free and well-drained.
  • Never plant them in shallow chalky, and soggy soils.
  • Ensure that the planting site is sunny, with rows running from north to south.
  • Ensure that rows do not shade each other.
  • Avoid planting the raspberries in windy spots.

How to take care of the plants annually

Below are the tips that you should try to follow for better raspberries plants:

  • Apply high potash fertiliser in early spring. One handful per square metre/yard is enough.
  • Prevent weed growing by adding well-rotted manure into the soil.
  • Water the plants well during dry weather conditions 

Pruning

Annual Pruning is vital for plants because it makes the plants healthier and better. 

Pruning the varieties that fruit in summer

  • Pull the suckers between the rows up.
  • Trim the fruited canes to ground level once you have harvested the plants in the summer.
  • Never leave the old stubs.
  • Tie the 6-8 most vigorous young rods such that they are 3-4 inches away from the wire supports. These young canes produce fruit in the following summer.
  • Remove the extra young stems also.

Pruning the varieties that fruit in Autumn

  • Prune the old and fruited canes to the level of the ground in February. Spring is the time when new canes will start appearing in spring.
  • Reduce the overcrowded canes in summer.
  • Thin out the canes to ensure a distance of 4 inches between them.

Planting

The best season to plant the plants is the dormant season between November and March. First, however, you have to ensure that the soil is not waterlogged or frozen.

You can plant the plants in rows and can plant them along with the wire system. Training along a single fence is ideal for raspberries that fruit in summer.

Here’s the step by step guide to training the raspberries along the single fence:

  • Place posts with 3 inches diameter and 8ft length to a depth of 30 inches in the ground.
  • Ensure a distance of 15 ft among the pots.  
  • Ensure a distance of 6 ft between the rows.
  • Surround the pots with 3.5mm galvanised wire at a vertical distance of 2 ft.
  • Tie the summer fruiting raspberries with the can on the side of the wires.
  • Ensure that fruiting canes are on one side and younger canes are on the other side. It will make the pruning process easy.  

Supports

Usually, raspberries are planted in rows and can be trained along with the wire system and post. Even the small space is not a problem for planting the raspberries. You can plant them in containers and train them with a single post.

Single fence system 

Autumn fruiting varieties grow well with this type of raspberries. Moreover, this system also ensures a better yield even if the space is not enough for raspberries that produce fruit in summer.

Parallel wires are enough for fencing the plants. So, there is really no need to tie up the canes. But, unfortunately, these systems are more vulnerable to severe fungal issues. Besides, it isn’t easy to pick them.  

Here’re some tips for planting the raspberries in a single fence system.

  • Place posts with 3 inches diameter and 8ft length to a depth of 30 inches in the ground.
  • Ensure a distance of 15 ft among the pots.
  • Support each post with two short horizontal timber pieces.
  • Surround the plant with 3.5 mm wire along the horizontal timber length, creating two parallel wire lengths along the fence.  
  • Stretch garden twine and thin wire between wires every 2 ft.

Support with cross ties and parallel wires is enough, and there is no need to tie the raspberries with the canes.

Single post

You must plant the raspberries using this method if you have a small garden.  

  • Place posts with 3 inches diameter and 8ft length to a depth of 30 inches in the ground.
  • Plant 2-3 plants around the base.
  • Tie the garden twine with the canes.

Planting

Here’re some other tips for planting the raspberries

  • Remove all the perennials weeds from the planting site.
  • Dig a hole in the site.
  • Apply general fertiliser and well-rotted organic manure in the planting site.
  • Ensure a distance of 10 inches between plants grown in rows.
  • Apply a 3 inches thick mulch layer.
  • Don’t apply the rich farmyard manure, alkaline mushroom compost because it can burn the younger shoots.
  • Prune the canes to 10 inches after planting the raspberries.
  • Don’t prune the summer fruiting raspberries because you can sell them as 1-year-old canes. 

Container growing

Growing raspberries in containers are easy. The size of the container for growing raspberries should be 15 inches in diameter.

  • Add 80% multipurpose compost for stability
  • Add 20% loam-based compost
  • Tie the plant canes with the bamboo canes
  • Water the plants to keep the compost moist
  • Feed the plants with general purpose fertiliser during the growing phase
  • Use harvested rainwater in the hard water areas

Harvesting

Early summer is the right time for harvesting the first summer raspberries. On the other hand, autumn raspberries will take time till the first frost.

If you want to have plump, richly coloured fruit at the peak of ripeness, you must harvest the raspberries regularly. Prefer harvesting the berries in dry weather to avoid them getting wet.

You can either eat them fresh or can preserve them.

Common problems

Raspberry beetle

Raspberries experience this problem more often. It results in the development of dry patches on the stalk end. Besides, you will also notice a small white maggot in the fruit.

Remedy

  • Pick off the fruit infested with beetle. It will not allow them to spread.
  • Consider growing autumn fruiting plants which have less risk to get affected.

Raspberry cane blight

It is also a severe fungal disease in raspberries. Its symptoms include

  • Withering of leaves during summer
  • The dark brown colour of the bases of the canes
  • Splits in barks
  • Brittle wood leading to canes that can be snapped off easily

Remedy

  • Water the plants well
  • Mulch the plant well around the base so that plants don’t dry
  • Ensure sufficient space between the plants while planting to ensure ventilation
  • Remove the affected parts of the plants
  • Disinfect the secateurs between the cuts

Raspberry spur blight

This fungal disease results in the appearance of purple patches on canes. It does not kill the raspberries but weaken the canes and kill the buds, resulting in lower yield.  

Remedy

  • Thin out the young canes to avoid overcrowding in early spring
  • Trim the affected plants on the development of spur blight.
