I have to agree with Byron that direct seeding tomatoes doesn't work everywhere. In our low desert, the growing season is also too short but mainly because of the heat. The best chance of success is to start the seeds around January 1, grow the plants to 1 gallon size and set them out in late February. If we were to wait until March when the soil is usually just warm enough to seed directly, we would be experiencing 95 deg plus temperatures by the time the plants start to bloom. Olin, Phoenix AZ
