Britain's favourite indoor black grape

The best-known heritage black grape for growing under glass. Also known as ‘Trollinger’ and ‘Schiava Grossa’ depending on the country of origin, this is Britain’s favourite black indoor grape. It’s reliable (mid-season indoors, late if outdoors), producing large bunches of sweet juicy grapes with delicious flavour, suitable for eating or wine-making.

A heritage variety originating in Germany, a Black Hamburgh vine was famously planted by Lancelot 'Capability' Brown at Hampton Court Palace in 1768. More than 230 years later, ‘the Great Vine’ is now over 120 feet (36.5 metres) long and produces an annual crop of 500 to 700 bunches of grapes weighing 500-700 lbs (220-320kg).

It can be grown in a large pot or greenhouse bed, in open free-draining soil or compost that is not too rich. While ‘Black Hamburgh’ can be grown outside in warm areas, fruit won’t ripen until late October, so can be damaged by an early frost.

It is important to regularly water your plant, at least bimonthly for two months. Grapes differ from other fruiting plants because their roots grow deep. Therefore it is important to give them a thorough watering. You should also ensure adequate spacing (1.8 - 2.7m) between vines, depending on the planting system you use. Please see below for our planting guidance:

  • Dig a hole that is twice the radius of your plant’s rootball.
  • Before planting, drench the rootball.
  • Place the pot in the planting hole, making sure that it sits no lower than an inch below the ground.
  • Fill the planting hole with a mix of compost and garden soil, finishing with fertiliser and mycorrhizal fungi. Take care to not compress the soil.
  • Provide your plant with a generous watering.
  • Add mulch on top, (whether bark and wood chippings, compost, manure, leaf-mould, and stones). Try to keep the mulch from touching the stem.
Depending on their location and hours of sunlight, grape vines can be slightly more challenging to grow. Below we address some common query topics:

    • Hardiness: While grapes originate from the Mediterranean and Central Asia, they are hardy enough to survive the UK's winters. However, they can sometimes suffer from frost damage. To avoid this, try to plant them in a south-facing location.
    • Position: When it comes to grapes, planting in full sun is always recommended.
    • Soil: Grape vines benefit from deeper soils, but 3ft is still adequate. Although the fertility and granularity of the soil determines fruit size, a smaller size is less of an issue with these plants. This is because their primary use is often wine making, where smaller fruits are preferred.
