It's really tough to 'speed up' the growing season. A nice sunny spot in the garden, well-prepared soil, and a proper watering and fertilization (note that these last two are just as easy to over do as they are to under do) are probably the best ways to ensure success.

Finally, if you live in a chilly climate, you can try to speed up the season a little bit by using walls-o-water or some other such device, but make sure you take care of the aforementioned necessities before you try this.

Why not post or check in over on the Growing Tomatoes forum here for lots of great FAQs and information.
