Potted tomato plant not flowering but healthy. Same plant in another planter. Is doing great. What could be deficient in soil?

Question

Plants purchased at Lowe’s, planted in Miracle Grow, soil 50% new and 50% soil from last year. One plant has plenty of flowers and tomatoes starting but other plant has none, both plants are about the same size and look healthy.

Answer 1

There are several possible reasons for one plant flowering and the other not. Have you checked whether this plant gets more shade or warmth at a different time of day? Could it be a variety that's different from the flowering one? Are they being equally fed? Are they more than two feet from the other? And, of course, it just may be that this plant is a late bloomer.
