Gooseberries: sweet, tart and finally mildew-resistant

Q: Are there thornless gooseberries?

Nearly thornless varieties like 'Pax' or 'Captivator' make picking far more pleasant and are mildew-tolerant at the same time. For something completely thornless, the related jostaberry has no thorns at all.

The classic bush has thorns, but there are now nearly thornless, tough varieties.

The gooseberry is an old friend that a lot of people have quietly lost sight of, often after a frustrating run-in with white fuzz and prickly thorns. Which is a shame, because it's one of the most rewarding berries you can grow: it gives you two completely different harvests. And both of those old headaches are solved these days, simply by picking the right variety.

Two harvests from one bush

Cook them green, snack them ripe

That's the special appeal of the gooseberry. As early as late May and into June (roughly CW 22 to 25) you can pick the fruit while it's still green and firm. It's tart and perfect for cakes, compote, jelly or chutney.

Leave the berries on the bush a while longer and, from late June through August (roughly CW 26 to 31), they turn fully ripe, soft and sweet, perfect for snacking straight off the branch. So the same bush hands you two completely different fruits.

Green, yellow or red

Depending on the variety, gooseberries come in a lovely range of colours, and the colour often gives away the flavour.

Green varieties are usually fresh and tart, yellow ones delicate and aromatic, and red ones, when fully ripe, especially sweet. All of them are rich in vitamin C and fibre. In terms of flavour, that makes the gooseberry more versatile than almost any other berry in the garden.

The arch-enemy: mildew

When gooseberries fail in the garden, American gooseberry mildew is nearly always behind it. It coats the shoot tips and fruit with a greyish-white felt that later turns brown, and it makes the harvest inedible.

Mildew: beaten by choosing the right variety

The best and simplest prevention is a mildew-resistant variety. Reds like 'Rokula', 'Rolonda' and 'Captivator' have proven themselves, along with yellows like 'Hinnonmäki gelb' or the green 'Invicta'. It also helps to give the bush an airy, partly shaded spot, an open cut that lets in wind and light, and a measured hand with fertiliser. Too much nitrogen pushes soft, susceptible growth. Cut out any infected shoot tips and dispose of them with the household waste, not on the compost.

Thorns? Not a given any more

The second old gripe was the thorns, which turned picking into a prickly ordeal. That's something you no longer have to put up with either.

Harvest almost thorn-free

Varieties like 'Pax' or 'Captivator' are nearly thornless and mildew-tolerant on top of that, which makes them ideal for families and easy picking. If you want to skip thorns altogether and get two berries in one, reach for the jostaberry, the thornless cross between gooseberry and blackcurrant.

Position and planting

Unlike a lot of berries, the gooseberry doesn't like it too hot. A partly shaded, airy spot is often better than a baking south-facing wall, because it heads off mildew and sunscald on the fruit. The soil should be rich in humus and evenly moist. Since the gooseberry roots shallowly, it's better to mulch than to hoe deeply, and that keeps the moisture in the ground.

A tip for small gardens and for gardeners who like it easy: the gooseberry also comes as a standard (a tree-form on a stem). It stands airily, dries off quickly after rain (again good against mildew) and lets you harvest without bending your back.

Pruning for air and light

With the gooseberry, pruning has one clear goal: an open, airy bush where nothing stays damp. Like the redcurrant, it fruits on older wood and on short fruiting spurs.

Build the framework
In the first few years, train up eight to twelve strong main shoots, spaced loosely apart.
Clear the inward and downward growth
In winter (roughly CW 6 to 9), cut out any shoots that grow into the centre or hang down towards the ground. That brings air and light into the bush.
Renew the old shoots
Take out the oldest, dark shoots close to the ground and let younger ones move up. Fruiting wood that's two to three years old bears best.
Keep it airy
An open framework is the best insurance against mildew, and it makes picking between the thorns a good deal more pleasant.

Stopping the sawfly early

Besides mildew, there's a second visitor worth knowing about: the gooseberry sawfly. In spring, its green, caterpillar-like larvae can strip a bush down to the leaf veins in just a few days.

Check the undersides of the leaves

From bud break onwards, check the undersides of the leaves regularly, especially deep inside the bush. Spot the little larvae early and you can simply pick them off before they do much damage. A healthy, airy bush and helpers like birds usually keep them in check anyway.

Green for cooking, ripe for snacking, plus the right variety to beat mildew: that's how the gooseberry becomes a favourite in the bed again.

Häufige Fragen

Can I eat green, unripe gooseberries?

Yes, and it's a real delicacy in its own right. Picked green, they're firm and tart, ideal for cakes, compote, jelly or chutney. Leave them on the bush and they ripen fully into something sweet you can snack on fresh.

Why is my gooseberry getting a white coating?

That's American gooseberry mildew. The most effective prevention is a mildew-resistant variety, backed up by an airy, partly shaded spot, an open cut and a measured hand with fertiliser. Cut out any infected shoot tips.

Are there thornless gooseberries?

Nearly thornless varieties like 'Pax' or 'Captivator' make picking far more pleasant and are mildew-tolerant at the same time. For something completely thornless, the related jostaberry has no thorns at all.

Do I need two gooseberry bushes?

No, gooseberries are self-fertile. A single bush crops reliably; a second one can nudge the yield up a little, but you don't need it.

At a glance

The gooseberry has earned a comeback. Pick a mildew-resistant variety with as few thorns as possible, give it an airy, partly shaded spot and an open cut, and it will hand you two harvests a year with almost no effort. Green for baking, ripe for snacking, and it does that for many years.

In Gartenkern you can set up the green harvest and the ripe harvest as two separate dates, and record the yearly thinning cut as a recurring task. Come next summer, you'll know exactly when your gooseberry 'Rokula' was ready for cooking and when it was ready for snacking.
