Types of Tomato Plants and Cycles of Growth
Tomato plants are one of the most popular garden grown vegetables. Though the tomato is thought to be a fruit, it is mostly used as a vegetable. Like other plants, tomato plants grow from seeds. As there are various types of tomatoes, the time needed to grow varies from type to type. Cherry tomatoe grows in about 65 days, while plum tomatoes take about 76 days to grow. Medium-size varieties mature from 50 to 81 days. Finally, large tomato plants mature anywhere between 62 to 80 days. Before selecting a type of tomato, the amount of time taken to grow should be considered first.
