Pure Blend Pro-- One of my favourites, made with kelp, Fish, Seabird Manure etc.. high in nitrogen. Reccomended for more sensitive plants or plants used for their leaves.
Plant prod 20-20-20-- another great fertilizer! This works best on plants used for their fruits or flowers, typically small annuals.
Cow Manure or any other compost-- Pretty much GREAT for every type of plant, i use a handful in every pot some time in spring
Shake n Feed-- Chemical 'Slow Release' granules that are usually balanced. I recommend using for all plants twice in the winter, and mostly Tropicals, Houseplants, or Trees throughout the year
