Hi, thank you for the kind advice and sharing your experiences. The bigger plant look better now but it's smaller brother is not doing so well. I will let time do it's thing. For potting I used Miracle Grow Organic soil and I use organic plant food liquid.

The problem is lack of water Period. OK. That seems like a long time to run the sprinkler for. You need to achieve 3/4 to 1" of water no matter how long it takes. Try a different rotor head that will throw more water, or change the nozzle in your current heads if you can. Honestly, running it for 45 minutes drenched the yard! Thats because we just received 3 days of soaking rain. It also doesn't explain why one of my problem areas received more water. If the problem was not enough water, it should be receiving less, right? Your talking about an 1/8" difference. If it would have been 1/2" or more difference then you might have an argument. What makes you think it's not enough water? Because you only applied an average of 3/16" of water. Can it be fungus? Chinch Bugs? No and once again, even if it was chinch bugs, you already treated for them. We have sandy soil in the Tampa Bay area. The problem areas you have are DEAD and are not going to get better over night. The good thing is that S.A. spreads by runners fairly rapdily. You could/should apply some compost to the dead areas to help/speed the process up. I strongly advise you read this whole thread again and follow the advise. By spring/early summer your problems should be much much better.

Thanks for the reply. The plant looks great and keeps setting fruit but the same thing happens. Are you familiar with the TNT tomato fertilizer I use? Maybe I should double the amount on the directions? Is it possible to apply too much phosphorous?

Holly - I had exactly that issue. The good news is that it was easily solvable. When I realized by cutting board, etc. didn't fit, we called the granite installers. The woman on the phone said we should call Home Depot. ??? So we talked to her boss and he sent out the guys to have a look. The Kohler sink is long and likely to get a bow in the long side somewhere along the way. They saw exactly what the problem was and fixed it by gently and progressively wedging a padded 2x4 or two across the width all along the long sides. I think they had to release the silicon on the one side to make this work. Essentially they were pushing the bow back out to straight to get back to rectangular. It didn't take long, less than 1/2 hour from beginning to end, and nothing was damaged. All fixed and good as new. Love this sink.
