I live in the Udine area.
I have a pear tree and one of plums of about 3-4 years (about 1 mt high),
to move to another place.
When should I transplant them?
Is it already too late now?
the transplantation of fruit plants is carried out when the plant is in vegetative rest, in order to guarantee the least possible stress, in spring it is good to avoid moving the plants, first of all because in February-March it is still possible that at night check for frosts, which would irreparably ruin newly shifted plants, in addition to this the demands for water and mineral salts for the plant are at a maximum level: moving it in this period, in which it is already working at full speed to produce flowers and leaves, it would be an excessive stress, which could also lead to the death of the plant itself.
So, if you can wait, keep the two plants where they are, and wait at least the second half of September, or the first half of October; moving the plants in this period, they will be in complete vegetative rest, so the transplant will not spoil them, and they will have enough time to settle before arriving the following spring, and therefore you will not lose the fruits of the following year.
I remind you that during the transplanting of a small tree it is good to follow some precautions, so as to minimize any damage done to it.
Your plants are still small, and this feature will make the job easier.
It will be fundamental to try to remove a fairly large earthen bread from the soil, in order to move all the root trees of the saplings, without damaging it; so get ready to dig a large hole around the saplings, to extract a large earthen bread, which should not be touched, so as not to ruin the roots.
In addition to this, take advantage of the transplant, to prepare in the area where you will place the plants, an ideal soil; therefore, even in the place where the plants will live, prepare a large hole, and work the soil well on the bottom, enriching it with universal soil and humus. Generally it is good to prepare the pit for the plant a few days before the transfer.
When you move the plants try to put them at the same depth as they were in the previous site, so as to avoid burying part of the stem, which could be damaged or attacked by rot or fungus.
after the transfer, water the plants, and with the shovel, or even with the feet, try to lightly compact the soil around the stem, in order to stabilize the substrate in order to allow the plant to remain well straight and in position.
In general, the autumn months are not very cold, but they are quite humid, so later on you will no longer have to worry about the plants until spring.
