Since tomatoes and onions tend to grow well together, you will find that it is quite easy to do so, but there are still a few things which you should keep in mind before making a final decision of any kind. One of the most important things to consider when you are planting tomatoes and onions together is the time of year which you initially put them in the ground.

There is no doubt whatsoever that tomatoes grow best in the summer time, so you will therefore have to make sure that is when you plant them along with the onions. The great thing about planting tomatoes and onions together is that they have many of the same growing needs, including full sunlight and the same type of soil.
