Plant scientists consider them as fruit. Most other people think of them as vegetables. Whatever you call tomatoes, there are many different kinds of this popular and healthy food.
There are two groups of the plants. Small tomato plants grow to about one meter. They can be planted rather close together. Some short kinds do not require special care and are often gotten crop by machines. Large tomato plants can grow over two meters tall. They also produce larger fruits.
People who grow only a few plants can place wire cages around each one. The cage can be made of wire fence material. The cage helps the plant grow taller and produce a better crop.
Tomatoes often need extra calcium (Ca), or the fruits may be ruined. Add lime to the soil can solve this problem. Dry lands may also ruin the fruits. Tomatoes need water regularly. The soil should never dry out completely. Dried grass or leaves placed around the plant can help hold water in the soil and stop the growth of unwanted plants.
Tomatoes are native to South America. The tomato is a member of the potato family. The leaves of the plant are poisonous, like the leaves of its relatives. Before the 18th century, people grew tomatoes only as pretty plants. They called the bright red fruit a “love apple”, but would not eat it.
