I assume you are trying to grow the same variety of tomatoes. Any crop requires sunlight, water, nutrients and something to grow in - soil, water etc. 1. Tomatoes need good fertile deep soil. They need DEEP watering every 2-3 days. A little ground spray line just doesn't do it. A few comments back I gave some tips on growing tomatoes. Some people recommend you dig a trench 400-500 deep, throw in some fish heads/backbone etc, aspirin, Epson salts, compost/fertiliser. Put some soil back in and add some more compost/fert and mix it up. Still with the trench 200-300 deep plant the seedlings. As they grow fill the soil back in. Tomatoes are deep rooted so fert and water deep. 2. Zucchini need plenty of water also.

A few tips on growing tomatoes - make sure you have good rich prepared soil. Dig a hole 50cm deep and 60cm diameter. Put compost/manure into the soil or a hand full of fertiliser and mix it in. Plant the tomato in a bit of a hole and as it grows fill the hole in. Give tomatoes a good deep watering. Too much N and you will have a lot of leaves and little fruit. Too little fertiliser and you will have a small plant and a little crop. The secret is to know how much fert to put on and when. And start with a good strong seedling.

I think you might have blossom end rot, and root rot mixed up. Blossom end rot occurs on the base of the tomato, and is caused by a lack of calcium (usually -- it could be other things that cause the calcium to be unavailable - PH, lack of water etc.). Blossom end rot causes the tomato to look deformed. Calcium added to the soil at the time of planting is usually adequate to ensure this does not happen. The calcium really needs to be added EARLY in the growing stages. You could also use egg shells -- I would grind/smash up the shells pretty good then work them into the soil of the planting hole; better yet, enrich with egg shells over the winter and early spring in anticipation of future planting. Root rot usually occurs when water sits around the roots of a plant for long periods of time -- bad drainage, excess watering, soil that holds too much water (which is really drainage). If you have proper aeration this usually doesn't happen since the air flow will whisk away excess moisture (provided it isn't a swamp at the roots). Try to create updrafts in your pots -- you want water drainage holes that do double duty -- let the water run off and allow air in. I find that holes at the SIDE BOTTOM of the pot, rather than directly under the pot, work well. It may seem like a hole at the side of the pot will let the soil out -- but pretty much after the first watering this stops happening -- and once the roots take hold it certainly does not happen. No need for drainage material (stones etc.) -- just use soil/compost top to bottom -- expect soil to come out at first when filling the pot -- after that you should be fine. I make my holes rather large -- on a BIG pot these holes are about 3inches (circular). Roots of plants really like air (maybe not direct exposure) but they certainly like the occasional breeze through the soil. Face the hole on the shady side of the pot for a cooling updraft in hot weather.
