If you think it is a difficult practice, you are wrong. Here are all the useful information on how and when to repot a plant.
The repotting it is a cultivation practice that requires a lot of attention; the future of your plants depends on this operation, if done well you will have a luxuriant growth.
For those who do not have a green thumb, it might seem a complex operation, yet it is simpler than you think. In this regard we will illustrate you how to repot a plant giving you some very useful tips.
When to repot, period and timing
It is advisable to carry out the repotting for plants just bought in shops or nurseries: they are often sold in very small pots and therefore inadequate for their growth.
Plants with roots that come out of their container must also be repotted. How to know when it's time to repot? Generally, plants dorepotwith intervals of 2 years, except for plants with extremely slow root development or plants planted in extremely large containers to avoid repotting (as happens for the potted hedge).
Some flowering species such as azaleas and roses, repotting must be done when the roots have occupied all the space available to them, bearing in mind that it must still be done away from the flowering period. In both cases it is advisable to use terracotta pots with holes to facilitate the drainage of excess water. In extreme cases, it is understood that the time has come to do therepottingobserving the drainage holes: when the roots have reached an excessive development, they will be noticed from the bottom of the pot! Under these conditions the repotting it must be performed urgently as you have reached the limit.
For what concern period, it is said that each species has its own rules but all species should NOT be repotted in full vegetation and should NOT be repotted when temperatures are excessively high or low. That is to say that the right period for repotting always falls in spring or autumn.
In autumn, the plants that have stopped flowering are repotted (therefore in late autumn for southern Italy) while in spring repotting is done before the vegetative restart, therefore roughly between the second half of March and the beginning of April.
In late autumn and early spring, the plants are not yet in vegetative rest and not even at the height of their growth or flowering, in this way the roots can more easily get used to the new environment and the new condition and you can act without fear of stressing the plant. Repot in summer or winter only in an emergency.
Repotting plants and replacing the soil
For repotting, just remove part of the old soil, the most external part that comes off more easily. The old soil is removed and new, fresh and fertile ones are added.
ATTENTION: even if it is a necessary practice, it is good to emphasize that the plant is subject to a certain stress, therefore it will be necessary to follow a period of settling. After repotting, it would be better not to prune.
After repotting, avoid watering the plant for the next 24 hours if you have repotted in summer, 48 hours if you are repotting in spring or autumn.
Repotting the orchid
Some species need some particular care during repotting; among these we have orchids. These attentions consist in eliminating all the old substrate, in cutting old or rotten roots before placing them in the new pot with the new layer of bark. For every information: how to repot the orchid.
For the illustrated guide on hibiscus repotting, I refer you to the page: hibiscus, repotting and care.
Also in this case, for the specific guide, I refer you to another page: how to repot camellia.
Repotting and roots
The roots must always be handled with caution, especially when you are about to remove the old soil ... this operation must be done manually, wearing a pair of gloves. Care should be taken not to damage the roots when moving from one pot to another.
Given the delicacy of the roots, try to proceed with great care in handling them to prevent them from breaking. The new pots must also be equipped with draining material to avoid water stagnation that could damage them.
How much bigger should the new pot be?
Generally, the mistake is made of buying an excessively larger vase. If you carry out regular repotting, the increase must be minimal. It will not be necessary to buy pots with double diameter.
It is good to know that therepotting it should never be done in a much larger pot: too much soil around the roots would risk rotting the plant as the soil could become damp and muddy.
Remember that at the time of the repotting the new container must have a diameter of 8-10 cm more than the old one. Here too there are exceptions, in the case of plants that have roots that develop very slowly, the increase in diameter must be only one centimeter: this is the case of Hoya carnosa.
