First, the home test kits are notorious for being inaccurate so I wouldn't panic and yes, unless you did a whole bed sampling mix for your soil test (never test soil from just one location) you could have hit a concentrated pocket.

Second, plants will adjust to excess nutrient levels with time and use only what is needed - especially so with excess P & K. And high P should give you more blooms, not less so the problem, if any, may be something else entirely. ;)

Some extra watering will help container plants and might help some for in-ground plants, but it must be done slowly and with care to avoid creating new problems.

So what all did you add to the containers/garden in the way of fertilizers?

It probably heat. Cherry tomatoes set fruit better in heat and cold for that matter and that your cherries are doing well is an indication you soil is not the issue. Only a few tomatoes can set fruit when its in the mid 90's and up.you are in SoCal.

Watering frequency is often cited as a way to deplete nutrients in the soil. I believe it is yet another half truth stated incorrectly. Watering more often my even help to keep nutrients because if you are watering just enough. For example, a gentle watering that does not drain through the bottom of a container will not wash away anything. Heavy watering at at one time is what you may be looking to do for too much nitrogen. Though as I said it may not be an issue.

Lastly, tomatoes are also not heavy nitrogen feeders, they are best classified as moderate feeders. It is not a good idea to use fast acting rich nitrogen fertilizers on tomatoes. Heavy nitrogen users are typically corn, broccoli, cauliflower and lettuce. Any legume aka peas or beans need very little and will grow just as well on decent top soil.

I never operated with a plan. I just used what was available and sounded good. In this case, steer manure, super phosphate, bone meal, and plowed under bark nuggets (it was last year's mulch). I have also drenched the soil with a couple gallons of diluted kelp mix (GrowMore) to try to get more blossoms.

No, it's NOT the heat. In fact, this whole past week has been in the high 70's. It has not been a hot summer. After the first few tomatoes, everything dried up.

The Indian Stripe produced very well about ten tomatoes, and I was very pleased. (And it had exceptional taste). It has only one tomato left. The Black Pineapple produced three, one of which I tossed away early because of a hole. I have two tomatoes remaining on it, one per plant. The Burgundy Traveler produced three, with two tomatoes left on four plants. I got one Brandywine from one plant. --Zero-- Paul Robesons to date from two plants, although one has two tomatoes developing on it. (It's a huge sprawling plant, so there might be some more hiding there.) One Crimson Cushion from two plants. And almost all of that I picked before the fourth of july.

All in all, I have only had cherries to share with friends, but lots of those.
