Is my non compete agreement enforceable?

I signed a non compete with a lawn maintenance company called Floralawn who has been doing buisness in Lakeland for 19 years. I started off as the Account Manager and then they changed my title to Landscape Manager where they changed my title but no monetary changes I signed the agreement 6 months after working there. There are many errors in the form which seems generic and very broad. I started a small freelance landscape design business and they say I need to cease and decist. I have a degree and their company deals 85% in Lawn Maintenance and some landscape. The contract states Floralawn a lawn maintenance business. I was fired because I questioned my bosses follow thru. He asked me to do unethical things in the commuinty to try to win contracts from competitors. Would unethical business practices be a defense or that it does not state that I cannot do Landscape Design which is a different trade from lawn maintenance? Please help!!
