......the only thing that strikes me as weird is the "to much moisture" because its actually been really hot and dry here with little rain. but it seems like calcium is what i need.
It's not so much "too much Moisture" it's more
uneven moisture or
wide moisture fluctuations that help contribute to blossom end rot.
What's most important to understand about blossom end rot is it's a condition (
not a disease), a condition where there's a problem with calcium distribution
IN the plant (not always a lack of available calcium) with various causes....moisture fluctuation is one of those causes.
Keeping your plants evenly moist with mulch is one way to prevent or lessen the problem of blossom end rot.
~Dig
Blossom end rot caused by an imbalance of calcium to magnesium in your soil causing the plants to not absorb calcium. add a tablespoon of Epsom salt to the soil when you set out your plants.
lack of calcium is another way of sayin' your ph is off (a.k.a. too acidic) ..test the soil's ph , you can do it yourself with a simple kit or take it into a local co-op, they should be able to help you out
then add garden lime accordingly to balance your ph,
lime is basically ground limestone which is mostly calcium carbonate/oxide plus some magnesium (epsom salt is mostly magnesium) but you need to know how far off you ph is.
i think what happens is that the 'maters can't use the water properly in an acidic environment, so they become temperamental, too much water and they look like your picture, too little and the rot end is sunken rather swollen, you're not ever going to win with acidic soil, some species can tolerate it, but most can not
my 2 cents
It's all of the above! I grew potted tomatoes for the first time this year and remembered my gramma always limed the garden or used Epsom Salts. I did the Epsom salts when I planted them, and made sure that I only watered when the plants needed it (kinda wilty looking leaves) and never did I "water the entire plant". I made sure to only water around the stalk going into the ground. Splash back will cause problems as well. I had lush, full tomato plants and never lost a single tomato.
Info on Epsom Salts (I did not do the foliar feeding, but mixed the salts in my watering can and watered every 14 days to 21 days with the solution.)
[h3]How It Works[/h3]
Epsom salt replaces the magnesium and sulfur in the soil. Deficiencies in magnesium and sulfur make it difficult for plants to absorb nutrients they need for vigorous growth. Once the deficiency is corrected, tomato plants show rapid growth with robust stems and abundant fruit.
[h3]Application[/h3]
Epsom salt mixed with water and applied as a foliar feeder works quickly to restore magnesium to tomato plants that suffer from a magnesium deficiency. Complete coverage is recommended, and repeat applications may be necessary. Epsom salt applied to the soil processes more slowly than foliage feeders but provides the same benefits.
[h3]Application Rate[/h3]
Epsom salt can be applied either to soil or mixed and applied as a foliage feeder with a sprayer. Mix one cup of Epsom salt to 1 gallon of water and dissolve thoroughly to use as foliar feeder. For applying to the soil, use 1 tablespoon for each foot of height of the tomato plant and mix it into the soil around the base of the plant. Apply every 14 days.
[h3]Considerations[/h3]
Epsom salt does not build up in the soil and poses no dangers of over fertilization. It is
inexpensive and does not pose the risks associated with chemical fertilizers. Epsom salt is safe for the skin, but should be kept out of the reach of small children and pets. Many gardeners prefer to use Epsom salt as green alternative to chemicals.
