Alkmene apple: how to grow the heritage apple variety
Even though it is not one of the highest-yielding varieties, the ‘Alkmene’ apple is still popular for its delicious taste. Below is our guide to the ‘Alkmene’ apple and how to grow it.
The ‘Alkmene’ apple, sometimes called ‘Early Windsor’, is a heritage dessert variety that is highly valued for its exquisite taste. Unfortunately, this variety is barely seen in commercial apple production anymore. If you want to get your hands on this delicious apple variety, you may need to grow the hardy ‘Alkmene’ in your own garden. Here is everything you need to know to do this.

Origin and history
The ‘Alkmene’ apple variety originated in Müncheberg, Germany, where it was bred in 1930 at the Kaiser Wilhelm Institute for Breeding Research specifically for growing in drier regions. This was achieved by crossing the demanding English variety ‘Cox’s Orange Pippin‘ and the 19th century dessert apple ‘Duchess of Oldenburg’ which resulted in an early-mid season harvesting apple with a taste similar to the cox orange but slightly tangier.
‘Alkmene’ apple characteristics and taste
The small to medium-sized, round-shaped fruits of ‘Alkmene’ are remarkably similar to the ‘Cox Orange’ parent variety. Both have distinctively thin and smooth golden-yellow skin with orange-red colouring on their sunny side, as well as yellow-green, crunchy flesh. The particularly aromatic, honey-sweet and finely acidic taste is also reminiscent of the famous English dessert apple. Although its yield is regular and high, ‘Alkmene’ apples cannot keep up with the yield of common cultivated apple varieties such as ‘Golden Delicious‘, so it is rarely grown commercially. This early autumn variety is ready for picking as early as the beginning of September and is ripe to eat from mid-September to the end of October. Once ripe, unlike other varieties, ‘Alkmene’ apples will not drop from the tree.
From the end of April to the middle of May, ‘Alkmene’ apple trees will begin to flower: they produce beautiful pink and white apple blossoms over a particularly long flowering period. For this reason, ‘Alkmene’ trees are also very popular with bees and bumblebees. In contrast to the cox orange variety, it is much more resistant to mildew and scab, two of the most common diseases in apple production. However, ‘Alkmene’ apple trees are susceptible to fire blight, fruit tree canker, sunburn, and spider mite infestations.
Top tips for cultivating ‘Alkmene’ apple trees
‘Alkmene’ apple trees feel at home in mild climates. The ideal location for this robust apple is in partial shade as it tends to get sunburnt easily, which can reduce its yields. Unlike its parent variety, ‘Cox Orange’, ‘Alkmene’ trees tolerate dry to moderately moist soils. However, for this apple variety to develop well, take care to ensure that the soil is well-drained and rich in nutrients. Generally, the ‘Alkmene’ variety also tolerates windy locations.
Depending on the location and care, ‘Alkmene’ apple trees display a medium to vigorous, upright growth. However, with moderate pruning and sparing fertilisation, you can limit the tree’s growth for smaller gardens. As with other apple varieties, regular pruning is essential for long-term fruit development. You can find out the right way to prune your tree to achieve a good balance of new shoot formation and yield in our article on apple tree pruning.
Like all apple trees, ‘Alkmene’ trees have deep taproots as well as lateral fibrous roots. This means it is well equipped to absorb the nutrients it needs from both far below and near the soil surface. Nevertheless, fertilising can be worthwhile to support the healthy growth of your apple tree. But be careful: too much fertiliser can cause more harm than good!

Harvesting and using ‘Alkmene’ apples
‘Alkmene’ apples are an early autumn variety, ready to pick at the beginning of September. It is then ripe for eating from mid-September until the end of October. Unfortunately, ‘Alkmene’ apples are not very well suited as a storage apple, as they tend to rot easily and brown quickly. However, ‘Alkmene’ can usually be stored until the end of November if kept refrigerated at about 2°C.
Thanks to its delicate sweet aroma, the ‘Alkmene’ apple is perfect for eating fresh. Its tangy-sweet flavour is also a delicious addition to baked puddings like apple pie or crumble. However, if you want to enjoy your apples a little longer, why not try pressing a delicious juice from the apples or boiling them down with a little sugar to make applesauce.
