Growing Tomatoes

upside down tomatoes black on the bottom

17 years ago

I am trying an upside down tomato plant, along with the six that are in the ground. They all seem to be doing fine, except that the tomatoes on the upside down plant are black on the bottom. They are about an inch in diameter at this point. Any thoughts? Too much water? They all get the same amount of sun.

Might be the dreaded BER. Might already be too late, but your tomatoes there might need some lime, bone meal, or other fertilizer high in phosphorus.

Right, it is called BER (blossom end rot) and I have linked to the FAQ on it below.

If you search both terms here you'll find many discussions about it to review if you wish. It is more common in wet springs, more common in pate type tomatoes, more common in container plants, etc. Most of the time it goes away all on its own as the plant matures and adjusts.

I just assume that the first 1 or 2 fruits from each tomato plant will be BER'ed or catfaced. Rules of the game...
