When to repot the hibiscus?

For the cultivation of hibiscus in pots, it will be necessary to provide decanting every 2-3 years. Choose a slightly larger pot, the diameter of the new container should be 3-4 cm higher than the previous pot.

The right time to transplant the hibiscus

In general, it is always the right time to perform arepottingas long as the root system has not suffered. This is why it is not recommended to repot in winter, late autumn or early spring when the roots can still be tested by low temperatures.

The best time to transplant hibiscus falls between late spring and summer.

When repotting the hibiscus, in addition to the largest container, you will need new, rich and soft soil.

Hibiscus, repotting

In late spring it is possible transplant the hibiscus in the open ground or run thedecantingusing larger containers. Repotting, depending on the conditions of the plant, can be a very simple or extremely delicate operation. If the repotting is done every 2-3 years, this will be simple because the root system will be easier to manage.

How to repot hibiscus?
First, get some soil rich in organic matter and 1: 4 perlite. If you already have expanded clay at home, you can use that instead of perlite.

  • - Preliminary irrigation
    A few hours beforerepotting, water the hibiscus abundantly.
    Irrigation must be such as to impregnate the perimeter soil contained in the pot. This means that you have to irrigate, wait until the soil has absorbed a lot of water and then give more water.
    This procedure will help you to detach the soil more easily from the walls of the pot without having to stress the plant.
  • - The new container
    Prepare a pot that is 3 - 4 cm larger than the previous container. If you have not used a mixture of soil and perlite (perlite makes the soil more draining avoiding stagnation) fill the bottom of the pot with a layer of a couple of centimeters of expanded clay (expanded clay, just like perlite, will will avoid repotting).
  • - The soil
    After the expanded clay layer, add a generous layer of soft, fresh and organic matter rich soil. Repotting does not only serve to give the plant more space to allow the development of the roots, with the repotting we give the plant a new substrate, essential for growing in pots.
  • - The actual repotting
    If you have watered enough, when you try to lift the plant with the base of its trunk, the pot will remain level while you find the plant with its stick of earth. Observe the stick of earth, if in the lower part it is devoid of roots, remove the old soil, eliminate the perimeter soil ... the only area where you do not have to remove the old soil is the superficial part ... if you are very experienced, you can eliminate the old soil also from this area but if you are a beginner it is not recommended because you could risk burying the collar excessively ** or leaving it exposed to the sun.

The following photo shows the two phases of repotting the hibiscus.

After irrigation, all you have to do is lift the hibiscus from the pot and move it to the new container already partially filled; to finish, add some fresh soil to completely fill the new pot and bring the plant to level.

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.

** the collar is that part of the plant that connects the stem to the root. This area must be perfectly level with the ground, if left uncovered, the hibiscus will risk drying out suffering damage from the sun. If you are not practical and it is your first repotting, avoid moving the soil at the base of the plant and just add some fresh side to the old earthen bread.

Some advice on care:
do not overdo the fertilization! Excessive fertilization stops the flowering of the hibiscus, in fact, if you notice your plant thriving and full of leaves but without flowers, it is probably the result of excessive fertilization.

Closed flower buds indicate a lack of light, so move the vase with the hibiscus to a brighter area. Hibiscus pruning is only necessary after the first three or four years of cultivation, it is performed to eliminate the sick or dry parts and to model the shape of the plant.
