It has been a cool spring. This year we decided to plant three tomato plants in planters, so we could start growing them on our patio.  We move the plants into the garage most evenings because it still cools off near freezing. They are becoming beautiful plants.  The question is are you suppose to pinch off the blooms at first so the nutrients go into the plant or so you leave them on the plants?  I have heard it both ways.  Anyone know?
