In my blog last week, I closed off by saying that the best types of fertilizers for indoor plants are those which come in liquid or powder form.

Of course, to choose a fertilizer, you must take into account your plant’s needs. For example, if your plant is about to flower, then a fertilizer with a stronger concentration of potash will encourage plant vigor. On the other hand, if you find that the leaves of a given plant are beginning to look anemic, a fertilizer with a stronger concentration of nitrogen would be better.

Also, of course, organic fertilizers are what I recommend.

Fertilizers which come in pellet form, used for outdoor gardening, are not recommended for indoor plants because they take too long to dissolve.

There are no strict rules when it comes to the frequency at which you should fertilize indoor plants, except in those cases when artificial lighting is widely used. Because plants exposed to artificial light are constantly exposed to light, they cannot really differentiate between seasons and/or day and night. Therefore, they can be fertilized once a week; however, be sure to water them with clear water at least every four to six weeks in order to get rid of excess fertilizing matter present in the soil.

Plants exposed to natural (sun) light do not need to be fertilized as often. A good time to fertilize is when you start noticing that your plant star to form new leaves. It is not always necessary to follow product instructions. Many times, you will be the best judge of when it is opportune to apply fertilizer. It is a good idea to fertilize a flowering plant repeatedly when buds start to show, right until the actual appearance of the flower. Plants with large leaves tend to grow more slowly and require fertilization only about every three months or so. However, the sudden yellowing of these plants’ leaves may be a signal that fertilization is called for.
