  1. Hey,

    I am from chennai and I am trying to grow tomatoes in grow bags. The plants I got look like they are determinate and have started flowering. The problem is that blossoms are dropping and I am not sure what I can do about it. They are about two two feet tall. The variety is matchless.

    I read that humidity and temperature in chennai does not help when it comes to pollination. So I’ve used a vibrator to help with that.

    Any suggestions?
