Description

The columnar habit and small size of the Courson delfloden apple tree make it suitable for gardens with limited space, for growing in containers on balconies or terraces, or for creating a small fruit hedge. It is a self-fertile variety, very hardy, productive, and highly resistant to scab and mildew. The Courson apple is a delicious fruit with a round shape, fairly large size, smooth skin, and bright red colour on a yellow-green background, with few lenticels. Its crisp, white and firm flesh is very juicy, fruity, and sweet, with no acidity. The fruits can be consumed from late September and can be stored until November. With a high sugar content, it is a refreshing apple to bite into. It is excellent for pies, compotes, or sautéed dishes, and is also greatly appreciated in savoury recipes. Having other apple tree varieties nearby will improve pollination and therefore increase production.

Malus domestica, also known scientifically as Malus communis or Malus pumila, is the Common or Domestic Apple tree. It belongs to the Rosaceae family. Present in Europe since ancient times, it is a fruit tree native to the forests of Central Asia. It is very hardy and is probably the most cultivated fruit tree in Northern Europe. There are approximately 20,000 varieties, including around 10,000 of American origin, 2,000 of English origin, and 2,000 of Chinese origin. Malus domestica Courson® 'delfloden' is a recent creation by Georges Delbard Nurseries in France.

Elegant, the Courson Apple tree is a small tree with a columnar and compact habit that reaches a height of 3 to 4m (10 to 13ft) and a width of approximately 50 to 70cm (20 to 28in) at maturity. Its foliage consists of large, ovate leaves, dark green on top and pale green underneath, with deeply toothed margins. The white flowering occurs in April-May, which usually protects it from frost. The flowers are destroyed by temperatures below -2 to -3°C (28.4 to 26.6°F). The Courson columnar apple tree delfloden is a hardy plant that can withstand temperatures around -30°C (-22°F) and is suitable for cultivation in most regions. It is a partially self-fertile variety, but having other apple tree varieties nearby will improve pollination and therefore increase production. Columnar apple tree varieties such as Amboise, Azay-Le-Rideau, Ballerina Polka, Ballerina Maypole, Ballerina Valse, Cheverny, Chenonceau, Chinon, Pomfital, Rhapsodie, Sonate, Vaux Le Vicomte, Versailles or Villandry are suitable for cross-pollination. The Reine des Reinettes apple tree can also fulfill this function. Ornamental apple trees such as Perpetu Evereste and John Downie flower abundantly and can be excellent pollinators.

The Courson Apple tree is a vigorous variety with rapid and productive fruiting. The fruiting, which is homogeneous and abundant, begins in late September and extends until October. The apple can be consumed raw or cooked, in compotes, pastries, paired with cheeses, or as an accompaniment to savoury dishes such as black pudding, pork, or salads. Easy to consume, the apple provides a great feeling of satiety. Rich in carbohydrates and fructose, it is invigorating and rehydrating. Its high content of vitamins A, B, C, and E, minerals, antioxidants, and fibre makes the apple a health asset. The fruits can be stored until November, in a cool, dry place, protected from light, at a temperature of around 8 to 10°C (46.4 to 50°F), or in a cold room, sealed off from outside air, at a temperature of 1 to 3°C (33.8 to 37.4°F). Apples release ethylene, a gas that promotes fruit ripening. To accelerate the ripening of other fruits or vegetables, place your apples next to them.

Very popular for its fruit, the apple tree finds its place in the garden, bringing joy to both young and old. Among a wide range of apple trees, it is easy to find the variety that best suits your tastes.

Planting and care

Choose a well-sunlit location for your Courson Columnar Apple Tree. The soil can be slightly alkaline or acidic but not excessively so. Dig a large planting hole at least 3 times the volume of the root ball. Simultaneously add organic matter (topsoil, compost) and a base fertiliser such as crushed horn. Do not bury the graft point. Stake if necessary. For apple trees planted in isolation and in open areas, it may be helpful to stake them by installing a bracing system: plant 3 stakes in a triangle 50 cm (20in) around the trunk, and connect them together with pieces of wood. Protect the bark with a piece of e.g. rubber, and attach the stakes to the trunk with metal wires. Water abundantly, even in winter, and even if it rains. Fruit trees are ideally planted between October and March, outside of the freezing period. Container-grown plants can be planted all year round except during periods of high heat or frost.

The advantage of columnar fruit trees is that they can be planted in outdoor containers. Choose a container of at least 60L. Make sure the container is perforated and provide good drainage by filling the bottom with a thick layer of clay pebbles or gravel. In pots, your trees will naturally require more regular watering. In winter, move your fruit trees to a sheltered place away from the wind and stop watering during freezing periods. Practice surface dressing at least every two years, replacing at least the topsoil with fresh soil, and fertilize before flowering with a specific fertilizer that is not too rich in nitrogen.

In winter you can add a small handful of wood ash, around the base of the tree and lightly incorporated into the surface of the soil - rich in potash, this will improve fruiting. Apple trees can be subject to various diseases and pests. In order to limit risks, space the trees sufficiently, and install multi-species hedges, nest boxes or insect hotels to attract beneficial insects. In summary: prioritise biodiversity. The main diseases of the Apple tree are scab (brown spots on the leaves), brown rot (wilting of flowers and rotting of fruits on the tree) and powdery mildew (white powdery coating on the leaves). For these three cases preventive action is preferred by spraying a decoction of horsetail, or as a last resort and in case of severe attacks, a treatment based on Bordeaux mixture can be applied. As for pests, the codling moth (or fruit worm) is a small caterpillar, resulting from the egg laying of a butterfly, that causes tunnels inside the fruit. To remedy this, it is preferable to act preventively by promoting the installation of tits and bats through the placement of nest boxes. In case of aphid infestation, spray a solution based on black soap.

During the harvest in September, only keep the picked fruit. For good storage, it is desirable to place the apple with its stem downward, on shelves or in crates. Preferably choose a completely dark, dry and cool place, but frost-free.

Care

Pruning instructions The pruning of your apple tree can be limited to a simple thinning out of dead or obstructive branches at the end of winter, in March. During the first 3 or 4 years, you can also encourage the formation of 4 or 5 main branches, resulting in a goblet-shaped habit, which is traditional in fruit tree cultivation. Whatever the case, make sure to leave some spaces in the tree's structure for good air circulation and light penetration. Don't hesitate to thin out fruit clusters in June. Removing some fruits relieves fragile branches and helps achieve a better fruit size.
Pruning Pruning recommended once a year
Soil moisture Tolerant
Disease resistance Good
