Fertilizing

This depends on the type of plant, potting mix used, and the amount of light the plant receives. Check specific requirement for the individual plant.  In general it is best to stop fertilizing houseplants between November and March because the decrease in light slows plant growth and less nutrients are needed.  Plants receiving lots of natural or artificial light can be fertilized year round.  Let the plant's health and growth be your guide.  Most gardeners tend to overfertilize.  If in doubt, err on the side of less fertilizer - you can always do an additional fertilization later, if needed.
