‘Hedelfingen Giant’: the reliable cherry tree for difficult years

While many amateur gardeners worry each spring that late frost or heavy rain will destroy the blossom, there is an almost forgotten cherry variety that copes remarkably calmly with both. Give it a sunny position in the garden and it delivers not only sweet fruit, but dependable harvests even in challenging years.

Why so many cherry-growing hopes fail because of the weather

Cherry trees have a reputation for being demanding. A single frost during flowering can wipe out the entire crop. Heavy rain shortly before ripening can also split the fruit. Frustrated gardeners often give up, or choose varieties that are hardy but produce only average-quality cherries.

In many areas, springs are becoming more frequent in which commercial and home cherry growers are left with almost nothing. The trees flower early, a cold night follows, and all hopes are lost overnight. This is precisely where an old variety, selected in Germany during the 19th century and now regarded again as an insider’s choice, comes into its own.

“A historic German cherry tree demonstrates how reliable yields can be achieved despite late frost – without excessive use of chemicals.”

‘Hedelfingen Giant’: an old variety with modern strength

Known as ‘Hedelfingen Giant’, this variety dates from around 1850. Botanically, it belongs to the sweet cherry group (Prunus avium). It has moderately vigorous growth, usually reaching 4 to 6 metres in height and around 3 to 5 metres in spread. This makes it suitable for both traditional orchard meadows and larger home gardens.

By mid-July, its branches are laden with large cherries that range from dark red to almost black. Their flesh is firm, exceptionally juicy and distinctly sweet, making them ideal for eating straight from the tree as well as for jams, cakes and bottling.

The tree is especially notable for its exceptional productivity. Treated properly, it produces year after year and can seem more like a small cherry orchard than a single tree. Many owners report “baskets without end”, even in seasons when other varieties perform poorly.

Its secret weapon: the so-called ‘May bunches’

The secret behind this variety’s success lies in its wood: many branches carry dense clusters of flower buds, known in fruit growing as ‘May bunches’. These remain productive for several consecutive years – roughly four seasons in the same position.

• Dense groups of flower buds develop along a branch.
• They remain active for several years and repeatedly produce fruit.
• The bunches must not be torn off during picking.

Careful harvesting is therefore important. Removing stalks individually rather than pulling away whole bunches creates a kind of built-in yield guarantee. The same points on the branches continue to bear fruit every year, without the need for complicated pruning methods.

Hardy to -15 °C and ready for erratic climate conditions

The major advantage of this old variety becomes clear in spring. While many other cherries flower very early and are therefore easy targets for late frosts, ‘Hedelfingen Giant’ starts slightly later. Depending on the region, it opens its flowers from late March into April. As a result, many buds avoid the most critical frost nights.

The tree itself is considered hardy to around -15 °C. In sheltered locations where it is well established, it often tolerates even lower temperatures. It is therefore particularly well suited to:

• cooler upland regions,
• northern and exposed sites,
• gardens with a generally damp climate.

There is another benefit: its fruit is considerably less prone to splitting when heavy summer downpours hit fully ripe cherries. This avoids much of the disappointment after thunderstorms that can turn cherries of other varieties into pulp.

The tree also has good natural health. Many common cherry diseases occur much less severely, so it can be grown with significantly fewer sprays – something gardeners with a nature-focused approach will particularly appreciate.

“Less frost damage, less fruit splitting, fewer diseases – this tree is like a safety net for your own cherry supply.”

A boost for the entire fruit garden: a strong pollinator

‘Hedelfingen Giant’ does not only impress with its own harvest. Its abundant blossom attracts bees and other pollinators. When planted within reach of other cherry varieties, it can greatly improve their yields too.

It combines particularly well with traditional varieties such as:

• ‘Burlat’ – a very early, sweet firm-fleshed cherry
• ‘Napoleon’ – a traditional yellow-and-red cherry variety
• ‘Moreau’ – an aromatic dessert cherry
• ‘Van’ – a juicy, mid-season variety

Anyone with space for two trees can combine ‘Hedelfingen Giant’ with an early variety to extend both the flowering period and the harvest season. The bees repay this with plenty of activity, while the picking basket fills with more cherries.

How to plant ‘Hedelfingen Giant’ correctly

Planting is generally possible from November to March on frost-free days. Late winter is especially practical, once the soil has warmed slightly and can be worked easily again.

Choosing a site and preparing the soil

This tree thrives on warmth and light. A south- or south-west-facing position, protected from wind where possible, gives the best fruit quality. Deep, nutrient-rich, slightly loamy soil that retains water well without becoming waterlogged is ideal.

• Dig a planting hole measuring about 60 x 60 cm and loosen the soil at the base.
• Mix the excavated soil with mature compost; add a little sand if the ground is very heavy.
• Plant the tree with the graft union just above ground level.
• Drive in a support stake and tie the trunk loosely to it.
• Water thoroughly and mulch around the root area.

A mulch layer of bark chippings or straw retains moisture and helps protect young roots from severe drying out during their first summer.

The right rootstock for large and small gardens

For gardeners with plenty of room, a vigorous wild cherry rootstock is the best choice. It will produce a large, long-lived tree of the sort seen in old orchards. In smaller gardens, less vigorous rootstocks are more suitable. They restrict growth, keep the crown lower and make picking easier.

During the first few years, regular watering in dry weather and a bucket of compost in late winter are important. A light thinning prune, removing a few steep shoots growing towards the centre and allowing air into the canopy, is usually sufficient.

Harvesting correctly to secure record yields

Cherries from ‘Hedelfingen Giant’ generally ripen in mid-July. This is when the tree reveals its full potential. To preserve the May bunches, pick with care:

• Hold individual fruits, or pairs of fruits, by their stalks.
• Twist gently until the stalk comes free.
• Make sure that the thick bud clusters remain on the branch.

This keeps the productive areas of the wood active. The tree rewards this approach with steady crops over many years. For children, it is a garden highlight: it bears plenty of clearly visible fruit and even forgives the occasional less-than-perfect attempt at picking.

What new gardeners should also know about this variety

Anyone intending to use cherries in the kitchen will make a sound choice with this variety. The firm flesh holds its shape during baking instead of immediately running out. For juice and syrup, the dark fruit provides an intense colour.

Cherry fruit fly is a concern for many growers. ‘Hedelfingen Giant’ is not immune, but its firm skin and later ripening often mean it is affected somewhat less severely. Yellow sticky traps near the canopy and keeping the grass short beneath the tree can reduce pressure.

This variety is also interesting in the context of climate change. Milder winters, sudden cold spells in spring and severe summer thunderstorms all challenge fruit trees. A variety that flowers later, withstands frost to -15 °C and is less likely to split gives amateur gardeners a genuine advantage.

Anyone planning a new cherry tree should ask for this old variety specifically at a nursery. It is often displayed rather inconspicuously among modern cultivars, even though it may be exactly the tree that finally solves the cherry-growing problem in many gardens.
