More information

An interesting variety of Cherry tree for several reasons. Its late flowering makes it less susceptible to late frosts. Its fruits, red with purple flesh, are sweet and tangy, and they resist bursting very well. Finally, this variety is highly resistant to diseases. Offered here as a half-standard to facilitate harvesting and limit its size a little, it is a medium-sized tree (10 m (33ft) in all directions), requiring a sufficiently large garden. This cherry tree is suitable for all regions and will be satisfied with ordinary soil in full sun.

Description

Prunus cerasus Allegria Delbard Delkarsun is a variety of cherry tree with red fruits, whose purple flesh is sweet and tart. Its late flowering exposes it less to the risk of frost, which is a definite advantage in many regions. The cherries are resistant to bursting and are harvested in July. The half-standard shape makes picking easier, but a ladder will still be needed as it is a fairly tall tree. Highly resistant to diseases and cold, self-fertile, this is a highly recommended fruit tree.

The sour cherry, in Latin Prunus cerasus (also known as the morello cherry), as well as the sweet cherry Prunus avium, are the two main species that have given rise to most of the sweet cherry trees cultivated in our gardens. They belong to the Rosaceae family, one of the most important under our latitudes, both for fruit and ornamental gardens, as well as for wild flora. The cherry tree is a medium-sized tree, reaching 5 to 10 metres (16 to 33 feet) in height at maturity. Its rounded habit provides a beautiful shaded space, very pleasant during the summer. Its alternate and dentate leaves are shiny, dark green, and then turn a pretty reddish colour in autumn before falling.

This 'Allegria' variety is a creation of the famous Georges Delbard nurseries, renowned for decades for their fruit trees and roses. This cherry tree is grafted as a half-standard, which allows picking the lower part of the tree from the ground. However, its adult dimensions (about 10 metres (33 feet) in all directions) will require the use of a large ladder or a ladder, as the birds will take care of the top! From late March to late April, it produces white flowers, which, after pollination by insects, will give beautiful red cherries in July, with purple flesh, both sweet and tart. These fruits are very resistant to bursting, which is a big advantage in case of bad weather. When ripe, they can stay on the tree for 2 to 3 weeks. This is a self-fertile variety that does not require pollination by another tree. Thanks to its late flowering, this cherry tree is particularly suitable for cold regions that experience late frosts.

This Allegria cherry tree can be planted on a lawn, at the back of a flower bed, or in an orchard. It is a variety full of advantages and therefore a very good choice for gardens large enough to accommodate it. It will be a good start to an orchard, along with a mirabelle plum tree.

Planting and care

Easy to grow, the Cherry tree grows in all types of soil, acidic or chalky. It appreciates moist, light soils and fears heavy, clay soils. Choose a sunny exposure. In order to limit the risks of late frosts on the flowers, it is recommended to plant the Cherry tree in a sheltered position, facing west and protected from cold winds in regions that experience spring frosts. Planting is preferably done in autumn.

Loosen the soil deeply, remove stones and unwanted herbs. Add some sand to improve drainage. Dig a hole 4 to 5 times the volume of the root ball. Make sure to separate the subsoil from the topsoil. Mix bonemeal or well-rotted compost or potting compost with the subsoil and pour this mixture into the planting hole. Add a stake, then place the root ball, cover with the topsoil and firm it down. Water generously. Attach the stake to the plant, crossing the tie in the shape of an 8, without tightening it around the trunk to allow it to grow without being strangled (to be monitored over the years).

During cultivation, watering is not essential, but necessary in case of high temperatures, and in Mediterranean regions. Mulch at the base to keep it cool in summer. Protect your harvest by installing a bird net if necessary. In case of aphid attack, spray diluted black soap in water.

Care

Pruning instructions Cherry trees are pruned in the green, meaning when they still have leaves, just after the harvest. This pruning should remain superficial and is often unnecessary. The cutting of large sections should be very occasional as it weakens the trees greatly. The use of healing gum on the wounds will limit the flow of sap that weakens the subject. In early August, if necessary, shorten the shoots of the year and in late autumn, remove any dead branches.
Pruning Pruning recommended once a year
