Hi I just read your question about planting veges. at this time, I would say yes if you guess it will be at least 4 months till firet frost where you live. That enough time for them to mature for harvest. hope you have a good crop and enjoy as thats what gardening is all about.

I'm gonna be lazy and paste a reply I just wrote to someone else with a similar question
Teach a man to fish...

What you really want to be asking is "How do I determine what to plant now?", because you can almost always plant something. The decision is complicated, because it is determined by a number of factors: how much space do you have, how many are you feeding, what do you like to eat?

Here's where I recommend you start. Get a GOOD seed catalogue - I like Johnny's, but there are several. Each listing has a "days to maturity" entry, which in most cases means how long it takes to go from seed to harvest. Use that number to determine what you can plant by subtracting that number of days from Sept 15 (just to be arbitrary, which frost is). The date you arrive at after that simple calculation is the last "risk-free" day to plant that particular vegetable... BUT! I always push the planting date forward and back by a few weeks because most home gardeners plant too much, all at once, and end up with too many beans(for instance) for a few weeks and not enough in the weeks before and after.

Get a good book, too - start at the library. Try to find Eliot Coleman's Four Season Harvest or Jeff Ball's Square Foot Gardening, both have good explanations of this type of planning as well as a good overview of what you need to know to start.

And read the forums here relentlessly, the amount of knowledge, generously shared, is amazing.

- hope it helps!
