Taking care of an anthurium is easy once you have learned the basics of anthurium care. In previous articles, I have covered where to keep your anthurium and how to water it. In this article I will discuss how to fertilize an anthurium.
Improper fertilization of your plant can kill it, so it is important to learn how to fertilize it correctly. The most important thing to keep in mind is to never over fertilize your plant. If you are uncertain as to how much fertilizer you should give your plant, make sure you give it less than you think it needs. If you over fertilize your plant you can kill it. While, if you under fertilize your plant, the worse that will happen is that it will grow a little slower.
There are two types of fertilizer that can be used to fertilize an anthurium: slow release or liquid. With slow release, you apply it once and don’t have to apply it again for six months. With liquid fertilizer, you will have to apply it every week. In general, I recommend using slow release fertilizer unless you are willing to devote a lot of attention to your plant.
The main thing to look for in a fertilizer is an even ratio of nitrogen, phosphorus and potassium. To find this type of fertilizer, just look at the numbers on the bottle. They should be something like 15-30-15.
Once you have selected a fertilizer, you will need to apply it. To apply it just read the directions on the label and reduce the amounts you see there by 75%. Let’s say that the label says that for 8 inch pots you should apply 1 teaspoon, for an anthurium in an 8 inch pot you should instead apply a quarter teaspoon. As far as application frequency, a slow release fertilizer should be applied once every six months.
