This year, our tomatoes all have had cracks in them, some little, some
bigger. Happens as soon as they start to ripen. We're doing something wrong,
just no clue what..
any advice/help greatly appreciated,
Irregular watering usually causes cracking. A dry spell made up with a
soaking can cause the inside to expand and the skin can't keep up.
You can still eat the tomato but it won't keep as long. The easiest
solution to to ensure even watering. If you have a dry spell, don't
respond with a torrent of water. Instead, give them an even watering
every day. It may be hard if they're outside and subject to a heavy
rainfall...the best way to ensure this doesn't cause the cracking is
simply not to let the plants get bone dry. Mulching around them will
help retain the moisture as well.

Thank you both SO much. The problem isn't the weather, it's my ignorance,
ugh. I'd been watering them a decent amount every few days.. I heard
somewhere it's best to water a garden infrequently and deeply. It wasn't
this group, a magazine or something I think? lol
So I will water them daily now.. thanks again everyone!
Also, I should probably make this a new post, and will if I don't get
responses, but I'm new at all this and have so many questions. We have just
a few stalks of corn and one ear, the silk has been brown a week or so now..
how do you tell when it is time to pick it?
thanks again, both of you!
The watering schedule depends mostly on soil type and exposure. If you
have bare, sun-drenched sandy soil you have to water daily. If you have
mulched, shaded clay once a week is adequate. If you have drip you have
to water less than by hose. Also, heirlooms crack a lot more than the
standard varieties. I have very sandy, very mulched soil with
heirlooms, and drip. I try to water every second day, though being out
of town some time leads to some irregular watering and to some cracking
in the tomatoes.
I have no special knowledge, only my observations from growing in heavey
clay. I use drip irrigation (emmiters every 12 inches, 1/2 gallon per
hour) and let the water run for about an hour. I continue this practice
unless I start to get overwhelmed with the quantity of ripe tomatoes.
When this occurs, I reduce the watering to every other day, or less,
depending on whether the ground is still damp just below the surface of
the soil. I don't want the ground to become dry. I've been doing this
for about 6 years and haven't had any cracked tomatoes yet, except for
when the rains come. Then all you can do is gorge or can. Hope this
