Cut and winterize oleander – what care the plant needs in spring. Pruning and fertilizing promote the flowers.
For older plants, repotting is only necessary every two to three years. For younger ones, it is recommended every year to promote growth. Even if this is not on your plan this year, the plant will still appreciate some fresh soil. A long-term fertilizer for Mediterranean plants is enough for about half a year. Additional nutrients in the form of liquid fertilizer are important every two weeks at the latest.
