Missing Tomatoes

The tomato plants have continued to grow and are now too tall for me to reach - I will need a ladder to pick them. Of course, based on what they have produced, that may not be an issue. I've gotten a few good-sized cucumbers, but only a couple cherry tomatoes. It seems that all of their effort is going into height. The plants are flowering, but most of the flowers are falling off without producing fruit. Any ideas?

Giganto Tomato Plants

Last year my excitement at finally having a salsa garden died a quick death. Even with fertilizing and regular watering, the plants didn't grow much larger than the initial planting, then quickly turned yellow and shriveled. My luck has changed this year! I added a couple bags of good 'ol cow compost to the bed before planting and now I have tomato plants as tall as I am! Stephen and I joke that we will be picking tomatoes from the staircase windows shown in the photo below.

Besides the standard salsa ingredients - tomatoes, peppers, and onions - I also planted a couple cucumber plants. They too are growing like weeds and I'm hoping to have a few fresh cucumbers ready to eat next week. Stephen waters the garden for me every night and I'm certain that these are the healthiest plants I've ever had - including the gardens I had in Mankato. I've become obsessed with my success and even have nightmares about waking up to dead plants!

Keep your fingers crossed that my green thumb last through harvest.
