Is florist and baker business is good Idea. Very tough competition in today market. is it good time for a startup.?

Yes, if you enjoy such profession.

I have a diagram on my wall of the failure rate in startups each year over twenty years. Each line on the graph are practically identical. The point is the failure rate does not so much depend on it "being a good time," or who is in the White House or the State House.

The key to beating the odds is good planning. Prepare a comprehensive business plan, be sure you pick an appropriate location for your business, be prepared for hard work, and most importantly have sufficient capital, (being under capitalized is a startup's biggest and most common mistake).
