im growing yellow pear tomatoes on my balcony in miami. i was wondering when will i know to pick them as i was told that you can leave them on the plant for too long. is this true??
how much water should i put in a small pot with 2 seeds do i need plant food and do i need a special lamp for the plant if i get no sunlight or can i use just any lamp. thank you.
I want to start my own tomato plants and flowers from seeds this year. Do I have to have natural sunlight on them or can I do something in the basement with the lights on them? I have more space in the basement. thanks
