I'm a brand new gardener and have four tomato plants growing in my garden right now. My celebrity plant has grown really well, but I have only been able to harvest about three tomatoes off of it. After that, all of the tomatoes start to split open starting near the stem and working their way down. Does anyone know what would cause this? I live in Surprise, AZ, which is just west of Phoenix, so the temps here are in the 100s right now. I have them in a raised bed, which drains better than I would like using the soaker hose for 1/2 hour. This week I've started watering twice a day. Do I need to kick it up to three times a day?
Like I said, I'm brand new at this, so I have a feeling that I'm doing a lot of things wrong.
