Tomato plants growing, but grow very few tomatoes

[Francis Barnswallow]

I have 5 tomato plants that are growing nicely, but whenever the blossoms start to grow, they fall off.

Basically so far I'm just growing tomato plants to massive sizes that produce little to no fruit.

Why is this?

You live in Florida I see. What are the temps there. If it has been above 90 tomatoes don't flower well. If they do the pollen becomes sticky and wont' work.

That could be your problem.

[Francis Barnswallow]

It's been around 90 to 92 with a heat index of around 98. So is it the heat?

[gixxerific]

More than likely. If you can give them some shade they may produce better for you.

Franc,

Also, if you are still fertilizing, cut back on the N, switch to P and K.

Good call DDF.

You in South Florida have completely different seasons, planting schedule than most of the rest of the country... most everything you read will be written for the rest of us.

Here's a guide to growing veggies in FLA. Midway down the page, Table 3 is about planting dates for different veggies in North, Central or South FLA:

For South Florida, it says you can plant tomatoes from Aug to March. Personally I would think even March would be getting a bit late for you. But the idea is the rest of us grow tomatoes through the summer. You can't, but you can grow tomatoes through the winter, when the rest of us can only dream about home grown tomatoes while we look at the snow out our windows....
