Q: Some of my tomato plant’s flowers are drying up and falling off. What’s up?

Flower drop on tomatoes is usually temperature related, e.g. below 12ºC (55ºF) or above 25ºC (75ºF). Other possibilities include uneven watering or too much nitrogen in the soil. Plants may be thinning some flowers since fruit production is very demanding on the plant system, so the plant needs water to grow and survive but it’s also required to develop fruit.
