Yes! You can fertilize in many ways...

Some make their own fert-cakes to put ontop of the soil. These are often made from bonemeal and bloodmeal, or rapeseeds. They are more "natural" than chemical ferts and are therefor probably a little easier on the plant if overfeeding.

You can add liquid ferts weekly, monthly or even daily. I use a very small amount each time I water my little victims... But you should be aware that chemical fertilizers in time will build up an excess of salts in the soil, causing problems for the roots. It's a good idea to "flush" the soil every few months or so. You can do this by simply, if you have indoor trees like me, placing the tree in a bathtub or shower and let water run trough the soil. You should try to let least 5-20 times the soil volume in water pass the soil, so that chemical build-ups will be flushed out...
