In Miami, you'll want to plant your tomatoes in the cooler months.....the typical summer months that you'd think to plant tomatoes are too hot here in Florida....the night time temp needs to get below 80 degrees otherwise they will flower and then the flowers will fall off and not produce any fruit. So our cooler months, although still warm are the best months for tomatoes as well as some other veggies.....like peppers.

Tomatoes usually take 90 days to harvest. Tip: you need good fertilizer and do not water every day; yes it promotes growth, but once the plant is planted and well watered, then you should water only once a week. Of course this depends on your environment. Watering less will trigger the plant to produce more flowers. Plant 2" deeper than normal Use: 1 cup of gypsum in the hole 1 cup of calcium in the hole Your Tomato plant will be happy.

Latest advice I got was this: Don't over water or feed your tomato seedlings!!! Your aim should be to deprive the seedlings of much water and fertiliser until they begin to bear fruit. That's right, when growing, feed them NO fertiliser and very little water! Just give them a pinch of Potash (Sulfate of ---) to strengthen the stem and the occasional watering when young. The trick is to make the plant think it is going to die (sort of like lowering its metabolism), so that it flowers and bears fruit earlier. You should note that the tomato plant WILL need extra fertiliser/water once it begins to fruit. You can also ripen your tomatoes inside the kitchen once they begin to change colour - there's no need to wait for them to ripen on the vine. It is said to dilute the flavour and increases the chances of letting the pesky birds get them first.
