With proper care, oleander grows quite quickly and can be very large and wide. Younger specimens in particular should be repotted once a year so that they can continue to grow vigorously and bloom profusely.

Oleander needs a large enough pot to grow healthily

When is the right time to transplant the oleander?

It is high time to transplant when the roots of the oleander are already growing out of the drainage hole at the bottom of the pot. Then you can be sure that there is not enough soil in the pot for the numerous roots. In many cases, the cramped roots also mean that the oleander does not bloom as profusely and its leaves turn yellow. The reason for this is the lack of nutrients, because in the narrow planter the roots can no longer absorb as many nutrients as are necessary for an adequate supply. Therefore, younger specimens should

  • be repotted once a year
  • the best time for this is in early spring
  • immediately after clearing out the winter quarters.
  • Older oleanders are only transplanted about every five years,
  • but also more frequently if necessary.
  • The exchange of the substrate is immensely important.

Planter and substrate - which one is the right one?

When transplanting, use a slightly larger pot that will comfortably accommodate the root ball. It is usually sufficient to choose the next larger container and shorten the roots before potting. Older and very large oleanders can also be easily planted in the old pot, but a root cut is essential. In this case, shorten the root ball by about a third and don't forget to cut back the above-ground shoots to the same extent. The most important thing when transplanting is the fresh substrate anyway, and you can mix it yourself or buy it in stores. Low-humus soil for Mediterranean potted plants is the right choice. Be sure to add slow-release fertilizer!

Transplant oleanders - that's how it works

  • Get the oleander out of its pot.
  • If this is difficult, use a sharp knife to loosen the roots and soil from the edge of the pot.
  • Now carefully tear open the root network with your fingers
  • and remove the old soil.
  • However, rinsing is not necessary.
  • Cut back the roots by a third (if desired)
  • and now place the oleander in a bucket of lukewarm water.
  • Now prepare the planter.
  • Place larger shards of pottery over the drain hole
  • and fill in potting soil.
  • Now hold the oleander in the middle of the bucket
  • and fill in the voids with soil.
  • Press the substrate down well and water thoroughly.
  • Also cut back the oleander above ground.

tips

You can also bury the oleander in the garden over the summer. However, you have to get it out again when a cold winter threatens. Do not remove the plant pot when digging it into the ground, but you can remove the cachepot, if there is one.
