We have one of the widest selections of crab-apple trees available in the UK.
Crab-apple trees belong to the genus Malus, and are therefore closely related to the mainstream apple (Malus domestica). They are grown primarily for their attractive blossom, and for the ornamental appeal of their pretty fruitlets in the autumn.
The fruitlets of many varieties are valuable in the kitchen for making crab-apple jelly. Several varieties retain their fruitlets into early winter (known as 'persistent'), providing a useful food resource for wildlife.
Many crab-apples also make excellent pollinators for fruiting apple trees, thanks to their profuse blossom and close genetic compatibility.
If planting a weeping variety it is generally best to tie the leader to a tall bamboo cane for the first few years. In the case of 2-year pot-grown examples you can cut back the tip by 3-5cm after planting, this will encourage more shoots to develop.
