Apple tree seedlings can be planted in spring and autumn, but it is important to consider what plants will be next to them.
Poorly chosen neighbors will ruin even very good seedlings. And if you plant the wrong plant next to a healthy and abundantly fruiting tree, it may start to wither.
In biology, there is such a concept as allelopathy. This is the ability of some organisms to secrete compounds (phytoncides, substances secreted by roots, antibiotics, etc.) that inhibit or suppress the development of others.
So, raspberry is considered a negative neighbor for an apple tree. It should be noted that the bush will not give a rich harvest, being next to the apple tree. The plants will mutually oppress each other.
To increase the harvest, it is enough to transplant the raspberries to the other end of the plot or move the young apple tree away from the raspberry patch.
Other unsuccessful neighbors for the apple tree are chestnut, birch, lilac, viburnum. Many plants do not get along with fennel, so you need to select neighbors for it separately.
