There is never a bad time, just some better than others, to plant. If I have space and seed, with a chance of maturity before frost, in they go.
Due to the wet weather in Southern Illinois, I just planted my second crop of sweetcorn and my first of greenbeans. Go for it, you will have some happy suprises. Be sure to mulch, while we have had a cool wet spring and early summer, you can bet your last gallon of gas we will have some hot dry days and will be looking for rain. Don
