Q.Tomato flowers fall off – no fruit
We have watered and fertilized tomato plants but one plant is forming flowers, then after a while, the flowers fall off without forming fruit. It is in a different spot in our yard. We have had great success with tomatoes in this spot before. What could be wrong? We are using the same tomato fertilizer as we always use.

No pollination, temperature fluctuations, soil content...It could even be the plant itself. This article will give you a list of possible causes, and what to do about them: https://www.gardeningknowhow.com/plant-problems/environmental/why-healthy-blooms-fall.htm
