Answer: If you're new to growing tomatoes in Arizona, you'll be surprised to learn that summer is not the best time to grow them! Planting tomatoes in late February or early March is usually the best time because they will ripen in 65-70 days, before the heat sets in. Timing is important because the pollen of most tomato plants becomes sterile at 90? F and tomato production often ceases during July and August. Pollen of the tomato variety Heatwave, however, remains fertile up to 95? F and the plant may set fruit over a longer period of time. You may still get some tomatoes from the plant you have, but it may just sit around until the weather cools off in September. Tomatoes are perennial plants so you can actually nurse yours along all winter and it should begin growing again in February and producing fruit in March and April. If you decide to grow tomatoes again, varieties named Early Girl, Celebrity and Heatwave are known to do well in Mesa and Apache Junction so they should grow well for you, too.
