Malus Domestica Delcorf or Delcorf Apple is synonymous with Delbar Estival. This is a mid-season dessert apple tree. Created in 1956, in France, this apple tree is the result of a cross between Golden Delicious and Stark Jonagrimes varieties. This mid-sized, spreading deciduous tree produces heavy crops of sweet, crisp apples.
Late to flower, blossoms emerge in May, completely covering its crown. Pale pink once they unfold, the flowers fade to white before they drop. They have a pleasant scent and are irresistible to beneficial pollinators, which is why this apple tree won the Perfect for Pollinators badge. The fruit follows in the autumn and can be picked from the tree in late September. The Apple Delcorf fruit is greenish yellow, flushed with red, somewhat larger than standard varieties. The taste of the juicy apple flesh is very sweet, honeyed and with hints of aniseed.
Easy to grow and to care for, Apple Delcorf prefers loamy soils, well-drained and medium fertile. This variety can be planted in full sun and partial shade, but growing it in a sunny spot will encourage a more abundant crop production. However, if allowed to crop too heavily, this cultivar can become biennial bearing. To ensure this cultivar yields fruit each season, thin out the excess apples early to mid-summer.
Since Malus Domestica Delcorf is not a self-fertile plant, you will have to plant a second apple tree of a different variety nearby for cross-pollination. In case you do not have enough space in your garden to plant more trees, you can rely on apple cultivars in your neighbourhood or pollinating insects.
Fully hardy in the United Kingdom, this dessert apple tree can survive even if the temperatures drop to 20 degrees below zero. Although quite robust, Apple Delcorf will appreciate sheltering from late frosts, as they can damage its blossoms. For its outstanding qualities and good constitution, Malus Domestica Delcorf received the coveted Award of Garden Merit by Royal Horticultural Society.
In addition to fruit thinning, this apple tree will appreciate routine pruning. The method of pruning will depend on the shape of the tree, but, as a rule of thumb, pruning once a year is sufficient to keep the plant in optimal shape.
Compact, with a lovely natural habit, this apple tree is grown for its decorative value as much as for the edible fruit it bears. Once fully mature, this tree will be around 4 to 8 metres high and across.
