How To Fertilize Your Anthurium

Proper fertilization of your anthurium is a vital part of anthurium care. Too much fertilizer can kill it and too little fertilizer means fewer flowers. To understand how to fertilize your anthurium, you must understand how its nutritional needs are met in the wild.

In the wild, no one walks around the forest with a big bottle of fertilizer and tosses it on to these plants. In fact, they are fed by two sources of nutrition. Leaf litter collects around their roots and as it decays it provides the first source of their nutrition. Second, massive dust storms from Africa blow across the Atlantic and deposit minerals on these plants as it rains.

This doesn’t sound like much in the way of sustenance and you are right, this really does not equate to much in the way of fertilizer. But it is more than enough to keep these plants growing strongly. The takeaway is that these plants require little in the way of nutrition. In fact, over-feeding them is a much bigger problem than under-feeding them. Over-feed and you risk killing your plant. Under-feed and your plant will grow a little slower. Which option do you think is better?

There are two ways to fertilize your plant. The easiest way to fertilize is to use a slow release fertilizer. Two good choices are Nutricote 13-13-13 or Osmocote 14-14-14. These fertilizers can last up to three months or more and will deliver nutrition to your plant slowly. Just apply a small amount and your plant will be fine for several months.

The harder, but more effective, way to fertilize your plant is to use a liquid fertilizer. If you choose to go this route you need to dilute it to ten percent of its normal, recommended strength and apply it on a weekly basis. This will take a lot more effort, but it can result in a larger plant with bigger flowers. But of course you must make sure not to over do it or you may kill your plant. Remember a dead plant doesn’t produce any flowers, so err on the side of caution.
