You can start weeding. That's the simplest way of dealing with them. There is no magic technique and weeding is a continuous process if you are going to be a gardener. Photos would definitely help.

What many people call "weeds" are simply plant you do not want growing where you do not want them growing. Floral is correct, just start removing those unwanted plants and keep at this process called weeding because it will be a way of life for you as it is for the rest of us.

Do not be afraid to ask questions because that is how we all learn, asking questions.

Personally, I changed my thinking about weeds when I started a compost pile. The need for a green layer is constant, and now I see all weeds and garden grass as an excellent source. I like to wait for a rain or soft soil and pull roots and all.

Weeding is a great, healthy physical exercise in fresh air and sun, badly needed in this age of TV and computers. So yes, start pulling your perennial weeds and cutting annuals.
