Why do my tomatoes keep going brown at the bottom.?

Answer 1

Same here! Add more calcium to the soil next year before you plant.
For now there is a calicum spray that you can buy to use on any tomatoes that are trying to grow right now (still green and not ripe that is).

Problems of Tomatoes
Blossom End Rot: Caused by calcium deficiency in the fruit, resulting from:

Lack of soil calcium;
Reduced levels of soil water and poor calcium uptake;
Internal plant water deficit during sudden hot periods; and
Nutrient imbalances which reduce calcium movement into fruit.
One of these disruptive factors causes a reduced level of calcium in the calcium pectate layer between cells. The blossom end is the last to develop and this is where the deficiency manifests itself. With reduced levels of calcium, the structure between the cells begins to collapse, thus rupturing these small, thin-walled cells. The surrounding cells have increased physical stress and they rupture (like a line of dominos).

Blossom end rot is usually seen on the first crop.

Control:

In May/June, when tomatoes are very tiny, apply a preventive spray of Calcium Chloride, which is sold commercially by several names such as "Tomato Saver" or "Blossom End Rot Preventer." Spray 2-4 Tbs/gal at blossom stage/tiny fruit stage and once per week for next 3 weeks.
Use mulch to maintain even soil moisture.
Water plants with 1-1/2" to 2" per week.
Use the Calcium nitrate form of fertilizer in proper amounts; excess fertilizer may encourage blossom end rot.
Plant resistant varieties if you've had problems before: Homestead or Walker.
Wait: problem often levels off/corrects itself after several fruit clusters have set fruit.

LIME NOW? No, lime is too slow-acting to help. Use calcium spray. (Also susceptible to Blossom End Rot: Eggplant, Watermelon, Peppers but calcium chloride spray is recommended for tomatoes only.)

Answer 2

It could be because they're too hot. You need to make sure you're watering them and keeping the soil quite moist, but if they're too hot the leaves and flowers will die.

If it's only the bottom few pairs of leaves that are going brown but you're still getting growth most of the way up the plant (most importantly, you're still getting the flowers) then don't worry about it. The first few pairs of leaves will naturally die off throughout the life of the plant to make sure the nutrients from the soil and water get to the growing bits of the plant. If this is the case, just cut the browning leaves off.

Answer 3

Its called blossom end rot. It means that there isnt enough calcium getting to the tomatoes. The reason for this is eather too much water (so the calcium in the soil is too diluted) or not enough water (so it cant travel to the fruit). Try and work out which one you're doind and adjust your watering. Those fruits that already have it can just be picked and thrown away.

Answer 4

My tomato plants are doing the same thing. Either too much water or not enough sun light. My deck doesn't really y get allot of afternoon sun, so that might be my problem. Next year, going to buy .them in the store. They are guaranteed

Answer 5

Just saw this on a gardening show this morning. They say it's too much water. Does you tomatoes have blight on them?

Answer 6

its called blossum end rot!its a vitamin defeintcy!here is a link that will tell you all about it and what to do about it!http://www.ces.ncsu.edu/depts/hort/hil/hil-28-d.html

Answer 7

Could be cuz they are laying on the grown.

Answer 8

Try to give more water.

Answer 9

the weight of the tamato squishes it

Answer 10
