Now is one of the best times of the year to start your tomato plants. Why, well you want to give them the best start to life and tomatoes need a long growing season to produce a good crop. I can hear you saying, it is too cold or too wet to start my tomato plants in the ground. Yes, I agree for the Northern hemisphere but you need to start your plants off in very early spring to be sure that they are good croppers. This applies in both the North and South. It is just that Spring happens at different times in the year in different parts of the world.
You need to judge when to start your tomato plants and mine go in during January. These will be potted on into larger pots and eventually put into the growing area of a greenhouse in May. This is giving me about 4 months of growing before they go into their final planting position and I would expect to start cropping my harvest sometime during July, probably towards the beginning of July. I will also be able to keep these cropping until late October and this is a growing period of nearly 10 months.
First of all you need to identify the best seed for what you want to produce and there are many different types of tomatoes to choose from. The seed type will also affect when and where to plant your seeds.
