Even though there is a great diversity in the varieties of apples, growing and caring for all apple trees is always the same. The only difference is how long some apple varieties take to mature, since some are early and others tardy.
Planting an apple tree
Fall is the best season for planting apple trees, as this lets the tree develop a sufficient root system before the onslaught of winter.
It is also possible to plant the tree anytime from fall to spring, as long as it isn’t done during frost spells; it is also possible during the summer except during heat waves.
When planting in spring and in summer, ensure regular watering.
- An apple tree requires sunlight to bloom and produce apples.
- It likes well drained soil.
- Adding fertilizer such as manure and seaweeds during planting will help the tree to take root.
- Water your apple tree regularly for the two first years after planting.
- To promote root growth, follow our recommendations on planting trees and shrubs.
Pollinating an apple tree
- Fertilization must take place between two distinct trees at least for the flowers to develop into fruits.
If you lack space to plant more than one apple tree, choose a self-pollinating variety such as: ‘Charles Ross’, ‘James Grieve’, ‘Egremont Russet’, ‘Arthur Turner’ or ‘Red Falstaff’.
- Note that planting only one variety, even if it is self-pollinating, might produce a smaller harvest than if you plant several varieties together.
Planting, pruning, and caring for an apple tree
In order to coax the tree into producing many beautiful apples, it is important to perform a fruit-inducing pruning before spring growth has started.
Pruning your apple tree should hence take place at the end of winter, when freezing no longer occurs.
- Adding special fruit tree fertilizer in spring boosts yields. Add a good-sized handful of fertilizer granules and rake them lightly into the surface of the soil.
- It is important to water regularly during the first 2 years after planting.
- Look up more information on the different pruning stages over the apple tree’s life cycle.
Preserving apples during winter
The best way to keep apples in winter for a long time is to place them in wooden crates, in a cool, ventilated and rather dark place.
- The ideal preservation temperature ranges from 40°F to 50°F (5°C to 10°C).
As regards fruits that have fallen to the ground, eat them as soon as possible because they’ve been damaged by the fall and would not keep for very long.
Apple tree diseases
Apple trees, like most fruit trees, are vulnerable to several common diseases, like fungus.
The most common apple tree diseases are scab and apple rot.
If an onslaught appears at the end of the cycle, when apples are already well-formed, degradation is limited and perhaps only a slight coloration of the apples may be observed. The harvest is not lost, but it is more difficult to keep the apples
However, if scab appears early in the season, it is recommend to treat it in order to stop the spread of the disease. An early onslaught of scab may hinder fruit development and compromise the harvest.
- A regular application of fermented stinging nettle tea as soon as buds have formed on the apple tree can prevent scab altogether.
- Spraying with Bordeaux mixture also protects against the spread of scab.
- There are a number of efficient chemical scab-fighting fungicides, both preventive or curative, but it is best to use them only once scab has already invaded the apple tree.
- Do not treat if you are only a few weeks from harvest.
- At the end of the season, gather all the leaves and destroy them to avoid letting scab hibernate in your garden over the winter.

European Brown rot
Another common ailment of apple trees is European brown rot, where Monilinia fungus strands rot fruits while still on the branch. This fungus can cause extensive damage to the apple tree and it is preferable to prevent it altogether.
- Similar treatments to those fighting scab are recommended.
- Fermented horsetail tea also produces very positive results against European brown rot.

Insects and parasites: aphids, scale insects…
If you observe that leaves of your apple tree become sticky and roll themselves up, you are certainly faced with an onset of either aphids or scale insects.
- Here is how to fight aphids
- Here is how to fight scale insects
- Set up pheromone traps in the tree
- A collar of sticky glue wrapped around the trunk protects the tree from many insects that would otherwise set up shop in the tree and on its leaves.
