There is a common misconception that growing blackcurrant bushes are very difficult. However, that is not true, as they are actually very easy to grow. You can even grow them in the ground directly. If you do not have enough space in your garden or yard, you can grow them in your pots.

Blackcurrants are one of the best plants on earth and the fruits come out in abundance around the mid-summer. You can use this fruit in jams and pies, and it is highly beneficial to your overall health and wellbeing. They contain plenty of vitamin C and your entire body system will thank you for it.

If you handle the planting process of your blackcurrant very well, care for it, and prune it appropriately, you will be able to get about 10 pounds (4.5 kg) of fruit. The fruits are highly preservative, as you can refrigerate them for later use.

You can also eat them frozen, fresh, cooked, or covert them to jam, jelly, and smoothies.

How to Harvest Blackcurrants Correctly?

On younger, new shoots, blackcurrant bushes produce many fruits. They will also fruit in abundance with minor pruning and less intervention within the first two to three years. If you buy blackcurrant bushes in the autumn and winter, chances are you bought it bare rooted. Mail-order nurseries usually deliver them bare root during this period of the year. In summer, they often come as potted plants.

Most of them are about one to two feet tall. Many gardeners recommend that you cut them to about two buds over the soil level, and this will help in the production of new shoots. However, they will also grow just fine when you leave them unpruned and plant them the way they are.


Pruning Blackcurrants


The pruning process is very easy and straightforward for the first couple of years (about two to three years). During this period, all you need to do is to prune out and take out diseased, damaged, low, and weak hanging branches. Your target should be to create a bush with about seven to eight strong branches.


Pruning Blackcurrants – The First Three Years

Blackcurrant bushes tend to produce fruits in abundance on the new growth. After about three years, mostly in the fourth year, you may start seeing smaller fruit crops on your blackcurrant bush. This is the stage where you need to get to work. At this stage, you need to give your blackcurrant bush its first proper pruning.

During late autumn and winter, you should take out about 40 percent of the older darker wood. You should take them to ground level, as they are less likely to yield more fruit. This process will provide more space for the formation of new shoots, which would be the major shoots that you ought to have. If there are any low hanging or weak branches, this is the best time to get rid of them. You need to remove them to prevent fruits from touching the ground.

After this first proper pruning in the 4th year, you need to repeat the process every year between late autumn and late winter. You should remove any diseased, dead, or damaged branch around the bush to give room for the new branches to flourish very well. Remember, you should only remove about one-third of those diseased, damaged, and dead branches. You should cut the branches back to good strong outward-facing buds.


What to do After Pruning Your Blackcurrants – Feeding and Mulching

After giving your blackcurrant bush the first adequate pruning it needs, the next thing you need to do is to feed it. If you want your blackcurrant to keep flourishing and growing fast, you need to feed it with a balanced fertiliser. There is an emphasis on ‘balance’ because it is very important. There are many fertilisers on the market, and not all of them are good for this plant.

We recommend you choose to go with a fertiliser such as Growmore.

You should spread the fertiliser around the base of the plant. You can check the labelling on the fertiliser to know the recommended quantity to use. After that, the next thing you should do is to mulch around the plant’s base. You should use well-rotted farm manure or great quality compost for mulching.

This process comes in handy when attempting to suppress weeds as well as retain moisture.


Tips for Growing Healthy Blackcurrants

Tips for Growing Healthy Blackcurrants

  • The key to the survival of any plant is proper hydration. You should water your blackcurrant in the growing season. You should also water it in the drier seasons to ensure it is always hydrated. When flowers and fruits are in their hydration phase, ensuring that they get adequate hydration is very important.
  • Pruning your blackcurrant bush between late autumn and winter is also very important. Most plants lose their leaves during this period because they are usually dormant.
  • There are different varieties of this fruit – modern and older varieties. An example of the modern variety is Ben Lomond, and they usually ripen together in bunches, which means you can cut them off in full bunches. The older varieties usually ripen separately. This means you have to pick the fruit individually as they get ripe. This makes modern varieties a lot easier to harvest than older varieties.
  • The planting process of blackcurrants is a bit different from that of other plants. Unlike many other plants, blackcurrants need to be planted deeply into the soil. Planting them deep into the soil will encourage lower shoots. It will also help new shoots to grow strongly from the base of the plant when you remove diseased, dead, low, and weak branches.
  • Also make sure that blackcurrant bush gets adequate sunlight when planted. They can also survive in damp soil but where possible, you should try opting for properly drained soil.
