  • You should also make sure that you use fertilizer on your plants. 
  • If you want to plant your tomatoes indoors, then you will need to make sure that you keep your plant area at a temperature of around 70 degrees Fahrenheit. 
  • You will also want to make sure that you water your plants thoroughly. Watering your plants thoroughly will help your plants to get bigger and produce more tomatoes.
