Question: Clivia

I need advice about my clivia: the tips of the leaves periodically (every two / three months) turn yellow and in some of them the yellow of a lot expands. I changed the position (putting it in a brighter corner), and I also reduced the watering, but the problem persists.
I currently water it once a week.

Answer: Clivia

Dear Stefania,
Clivia needs a lot of diffused but not direct light. The apical yellowing can be due essentially to two causes: a) excessive irrigation (to be excluded in your case); b) nutritional imbalances. In particular the excess of fertilizer manifests itself with leaves of intense green color with apical yellowing immediately followed by necrosis (desiccation); the nutritional deficiency manifests itself instead with pale green leaves and apical yellowing lengthened also to the rest of the leaf. Keep in mind that in this period the effort made by Clivia is maximum, due to the flowering or preparation of the seeds. In this case, it is advisable to irrigate fertilizers rich in nitrogen (for green plants) even twice a week in the doses indicated on the product packaging.
