How to Grow Redcurrants

Despite the resemblance to blackcurrants, the redcurrants’ growing pattern resembles gooseberries. Northern regions are the best places for these cool-climate plants. However, growth in the sun makes the redcurrants taste sweeter. 

Growing 

Here are some tips for the effective growth of redcurrants.

  • Water the plants in dry weather conditions.
  • Be careful in watering the long-establishes plants.
  • Ensure that the potted bushes don’t have dry compost. 
  • Make the soil weed-free manually.
  • 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. 

Pruning

The fruit of redcurrants appears on the old wood.

  • Remove the old and diseased branches in winter for pruning. Prune the newer growth for only two buds in early summer. It will help the plants stay compact.
  • Prune the leaders to the buds that face outwards.
  • Prune the leaders to the buds facing upward if the branches are bending.
  • Prune the established cordons in early spring.
  • Depending on the growth, prune the shoots on the central vertical stem by a quarter or by half.
  • Keep the growth straight by pruning by cutting to a bud present on the side opposite the previous year’s cut. 
  • Prune to one bud of newer growth in early summer.
  • Prune the shoots present on the main stem to one bud for building a spur system of fruits.
  • Place the containers on feet to enable the draining of excess water. It will prevent the plants’ roots from rotting in winter.  
  • Apply liquid fertiliser in the plants grown in pots every fortnight from late winter to early spring.
  • Remove the upper layer of compost every spring and replace it with controlled fertiliser granules and potting compost.
  • Repot the plants into an even bigger pot every three years.

Planting

The best time to plant the bare-root redcurrants starts from November to March. Bushes grown in a container are available for planting throughout the year; however, winter or autumn is the best time to plant them. Here are some tips for producing the redcurrants.

  • Choose sheltered and well-drained soil.
  • Make sure the planting site is sheltered from the wind and frost pockets.
  • Plant the bushes in the north-facing wall. However, it could cause late ripening with a less sweet taste.
  • Ensure that there is a distance of 1.5 m between the bushes.
  • Ensure a distance of 1.5 m between rows.

If you don’t have enough space, you must go for multiple cordons or single stem redcurrant. First, however, you must go for a goblet-shaped or open-centred bush with 8-10 branches over a stumpy leg of 4-6 inches.

You can also grow the cordon redcurrants in large containers at least 18 inches in diameter. You will need to fill the container with the John Innes No.3 compost.

Harvesting

You can pick the redcurrants when they are firm, richly coloured and juicy. Generally, they are ready to pick from early summer. You can cut whole trusses and use them immediately. Moreover, you can also store them for a few days.

Common problems

Sawfly

The larvae of the sawfly look similar to the larvae of the caterpillar. The pale green larvae defoliate the plants. It usually damages the plants in mid to late spring. Moreover, they reside over the plant for their three-generation. In a nutshell, sawfly prevails the plants through the summer. 

Remedy

  • Keep monitoring the plants from mid-spring onward to identify their invasion immediately. Examine the bushes and under the leaves. 
  • Remove their larvae manually.

Birds

Vegetables, leaves, buds, fruit and seedlings are the parts the birds eat the most. So, you must take preventive measures to save your plants.

Remedy

  • Bird-scaring or scarecrows helps prevent the birds’ attack. 
  • Use net or fleece to cover the plants.
