Leaving aside the basic design shortcomings of female gardeners, the old adage is Feed the soil, not the plant.
If you have the correct growing medium, be it soil in beds or planting composts, your plants will thrive. The trick is to know what growing conditions your plants like and that leads to another gardening adage - Right Plant, Right Place.
You can look up each individual plant in good gardening reference books - some of which have already been mentioned in other posts - or you can look at specialist sites such as the RHS or nurseries selling those plants. Then, as has also been said, get stuck in and plant something and learn from experience.
Technically speaking, compost is the term for what comes out of a compost heap made by mixing nitrogenous and carboniferous material in the correct ratio with water and heat to get the process going. However, compost is also used as a general term for planting medium which can be tailored to suit the needs of the plants eg ericaceous, loamy, moisture retentive, low nutrients for seeds and cutting, high nutrients for flowering and fruiting plants, nitrogenous for leafy plants and so on.
