Leaves: The leaves of a Crab Apple form on short stalks and are shiny and smooth. They are green in colour and ovately shaped with rounded teethed edges.
Buds: Buds of a Crab Apple are typically brown, scaled and pointed with downy hairs on their tips.
Bark: Crab Apple bark is a flecked, greyish-brown colour and their twigs, which often develop spines, are typically covered in lichens.
Form: Crab Apples are a small to medium–sized tree that has an irregularly rounded shape and a wide–spreading canopy. As a tree matures, they generally become more gnarled and twisted.
Flowers and Fruit: In spring, beautiful pink-tinted white blossom forms on the tree and proceeds to be pollinated by bees and other insects. Once pollinated, these then develop into small, yellowy-green fruits (apples) that once ripened turn red.
[Crab Apple Blossom]
Crab apples have a medium growth rate, typically taking between 20-50 years to reach their ultimate height which is averagely around 10m. However, they do have a lifespan of roughly 100 years.
The Crab Apple helps to provide a valuable food source to a range of animals and insects. For example, their leaves are often eaten by caterpillars of many moth species and their blossom provides an early source of pollen and nectar for bees and other insects! Their fruit, especially when fallen, can also be eaten by a range of birds and mammals such as blackbirds, mice and voles. This, in turn, aids in natural dispersion of Crab Apple seeds.
Properties of Crab Apple Wood and its Uses
Crab Apple wood provides a good quality timber which has an even texture and a pink finish. It is popularly used in carving and turning and when burnt omits a pleasant odour.
Styling of Crab Apples/Where to Find Them
Crab Apples can be found throughout the UK and Europe, thriving best in denser, more moist soil and areas of scrubland.
Associated Pests and Diseases
Unfortunately, the Crab Apple can be susceptible to many pests and fungal diseases, including the Apple Scab, Honey Fungus and Apple Canker which ultimately reduce the health of the tree. They are also occasionally prone to the Fireblight disease which gives the tree a scorched-like appearance.
Aphids, Woolly Aphids and Fruit Tree Red Spider Mites are also attracted to the Crab Apple.
Pruning and Pruning Qualities: Crab Apples are relatively easy to maintain, and it is suggested that they do not require vigorous pruning and that pruning should be kept minimal and simple.
The main intention of pruning a Crab Apple should be to maintain the shape of the tree, as well as to remove any dead, diseased, or congested branches. This helps to not only keep the tree healthy but also reduces the risk of any pests or diseases spreading.
Ideally, any pruning of a Crab Apple should be carried out when the tree is in its dormant stage, but after the stage where there may be a risk of severe cold weather. Typically, this will be in late winter to early spring.
