Do Blackcurrants Need A Pollinator?

In black currant (R. nigrum) almost all cultivars require insect pollination. The flowers are somewhat self-compatible, but the style and anthers are physically separated in individual flowers. However, all cultivars require insect cross-pollination to set a satisfactory crop.

Do you need two black currant bushes?

Not self-fertile; must be planted with another black currant variety to produce fruit. High yields of large high-quality berries are borne earlier – within three years of planting – than other varieties. Very vigorous, tall plants (to 6 feet) are immune to blister rust.

What is the best feed for blackcurrants?

But avoid heavy watering when currants are ripening, to prevent skins splitting. In late winter (February) feed with a high potassium general fertiliser, such as Vitax Q4. Scatter two handfuls per square metre/yard around the base. Alternatively use blood, fish and bonemeal.

Why is blackcurrant not allowed in America?

Blackcurrant bushes were grown in America back in the 1629s, but in 1911, the professional cultivation of the plant was banned. It is a carrier of a fungus called white pine blister rust. Hence, blackcurrant was declared illegal to protect pine forests.

Do gooseberries need pollinators?

Answer: Most gooseberry and currant varieties are self-fruitful. It is not necessary to plant two or more varieties for cross-pollination and fruit set.

What can you not plant with blackcurrants?

Blackcurrants do not grow well with companion plants, so it is best to plant them alone. However, they do tolerate other currant varieties, including white currant and redcurrant, and, as a major exception, wormwood.

Do blackcurrant bushes spread?

Blackcurrant varieties to try
Blackcurrant ‘Ebony’ – a good, disease-resistant variety, producing very sweet, large fruits from early to mid-July. Plants have a slightly open, spreading habit for easy picking.

How do you increase blackcurrant yield?

Prune the original branches back hard , around 6 cm (2-3 inches) above soil level. This will encourage new root and shoots growth. Allow a minimum of 1.2 m (4 feet) between plants. During the first year, give a feed of a general purpose liquid fertilizer every month and keep the plants well watered.

Is tomato feed good for blackcurrants?

Blackcurrant Plant Care
Additionally, we recommend applying a high-potassium liquid fertiliser (tomato feed is ideal) when the fruits start to swell in summer to boost production.

Do blackcurrants fruit on old wood?

Blackcurrants are grown as a ‘stool’, with most shoots arising from ground level or close to it. One-year-old shoots are the most productive. Two-year-old wood will produce some fruit but older wood becomes non-productive, so each year some stems need to be removed to make space for younger ones.

Why is it illegal to grow gooseberries?

In 1911, a federal ban made it illegal to grow all Ribes, including currants and gooseberries, because these plants served as an intermediary host of white pine blister rust.

Why is Ribena illegal in the US?

The nutrient-rich berries were banned in 1911 because they were thought to produce a fungus that could damage pine trees. As new disease-resistant berries were produced and new ways to prevent the fungus from damaging timber were developed, some states started to lift the ban in 2003.

Is Ribena illegal in the USA?

Current restrictions. By 2003 restrictions on Ribes cultivation had been lifted across most of the states, though some bans remain, particularly on the blackcurrant. State laws are enforced with varying degrees of efficiency and enthusiasm; in some states, officials effectively ignore the ban.

Why is there no fruit on my gooseberry bush?

If your gooseberry bush is young, it’s likely not ready to fruit yet. In many cases, it can take up to three years for your bush to begin fruiting. Even at three years old, it can sometimes take even more time to fully mature. So, if your gooseberry is below three years old, it’s best to wait.

Do you need 2 gooseberry bushes?

Gooseberry bushes are self-fertile which means you don’t need to plant two or more gooseberry plants together for a good crop. One plant on its own will produce a good a crop.

How big do blackcurrant bushes grow?

Blackcurrants grow not as a tree but as a bush with multi stems arising from the base. They will usually grow to around 5′ and the same across [about 1.5 metres] They are hardy, deciduous and strongly, pleasantly, resinous.

Will blackcurrants grow in shade?

Blackcurrants. These plants are easy to grow and produce a heavy crop of glossy currants that are rich in vitamin C. Plants tolerate light shade and can be grown in the ground or in pots.

Can you plant raspberries and blackcurrants together?

The site of the old raspberry bed can safely be a home to unrelated fruits such as currants, strawberries or rhubarb as long as it has been improved and fed well beforehand.

Can blackcurrants be grown in pots?

Blackcurrants can be grown in large containers (minimum diameter 50cm) in John Innes no 3 or multipurpose compost with added grit and plenty of drainage material in the base.

How often should you replace blackcurrant bushes?

“Happily ever after” with a blackcurrant bush should be about 15 years in most conditions before it should be replaced, so propagate new ones every decade to have mature plants on time. Pay attention to both the yield and the fruit diameter to decide when a plant is on the decline.

Is wood ash good for blackcurrants?

ANSWER: Wood ash is generally quite alkaline and can easily reduce the acidity of the soil where it is added. Fruit bushes prefer a slightly acidic soil so adding wood ash is not normally beneficial to them and can harm them depending on how much ash is added.
