Sooner or later all anthurium leaves get old and they die. When this takes place they start to turn yellow then they start to turn brown. That is completely all-natural and completely normal. When performing anthurium care, you are able to leave the old leaves around the plant and allow them fall off naturally.
But in general I want to trim them off, given that this tends to make our plants search better. Just keep in mind to sterilize your cutting shears just before performing this using a little rubbing alcohol. Or you can break in the leaves together with your hands, grasp the base of the petiole and apply a downward stress as well as the leaf must snap off.
For those who have placed your plant inside a spot exactly where it could get direct sunlight, it may possibly be getting sun burnt. If all of the leaves begin to turn yellow at the same time and then start to turn brown, this might be a sign of sunburn. Appropriate anthurium plant care dictates you need to move your anthurium to a somewhat less sunny area or make an effort to filter out a portion from the sunlight having a thin, filmy curtain. Or it is possible to have the window subsequent for your anthurium plant tinted. Should you use a curtain, keep in mind that it should not block out all of the sunlight. It should only block a portion of it.
In case your anthurium plant has started out increasing slower than regular or if its new leaves are smaller sized than its old leaves, it might be struggling from a nutrient deficiency. Deficiencies within the key macro nutrients like Nitrogen, Phosphorous or Potassium can all trigger leaves to turn brown, so can deficiencies in Calcium or Magnesium.
If nutrition will be the problem, you'll be able to resolve it by using a liquid fertilizer for any handful of weeks. And right after your anthurium plant has recovered it is possible to switch to a managed release fertilizer. When using liquid fertilizer dilute it to about 25% from the power proposed to the label and use it the moment per week. As soon as your plant recovers, you are able to use it every single two weeks or switch to managed release fertilizer.
