what kind do you have,what are they growing in, water,fert,sun. global warming, and your horescope.etc

Terry is right - we need more info please. Name of variety, why planted late, in containers or in the ground, what have you fed them, with all the rain in Iowa this year is your ground excessively wet, etc.?

If your plants are in the ground and were subjected to an excessive amount of rain and very wet soil then they may be suffering from root rot. If that is the case they MAY recover and begin to grow once the soil dries and the air temps rise into the normal range. But the damage may be too much. But this is just a guess without more info. ;)

It's possible for you to get a few tomatoes from those plants if they get proper treatment. Don't expect a 'strong' harvest by any means. You've got to have good soil, proper watering, proper mulch (I prefer compost) and sufficient sunlight to get them active. Fertilizer doesn't hurt as long as you don't poison them with too much. Get the conditions right and they'll take right off.

Sorry, I took the time to post a long message previously and it vanished.
They are planted in garden dirt mixed with a little composted manure in full sun.
We planted 1st week of June.
The garden was mud soup earlier, which delayed planting, and it has been unusually cold and wet til recently. The cherry tomato plants look decent, but Early Girls and Roma are runty.
They are not mulched and I haven't added any fertilizer. They have cages for support, and some have flowers and green tomatoes.
We've been having a good rain twice a week (or more) so I haven't watered.
Should I be watering if it only rains once a week? and how many inches should they get?
Should I add fertilizer?
Should I dig one up and see what the roots look like?

So I dunno...other people in town have nicer looking plants by now.
This is just my second year growing tomatoes and last year the tomatoes really took no effort.

Don't water unless the plants need it. If you have deep soil you may never need to water. Dig a hole when you think things are dry and see how far down the soil is dry. Tomato roots will go down 4 ft if they are able, but many of us have a clay hardpan under the topsoil so the roots only have access to the top foot of soil at most. That is why we need to water.

Waterlogged soil and cool weather will slow growth. The roots may not be rotted, just not have enough oxygen for nutrient uptake. If your tomatoes grew well last year and you did fertilize early on I don't think you need to add more for small plants. Once the soil dries out a bit the plant will grow new roots (if some were rotted) and take off, but there is a bit of a lag time for vegetative growth if new roots have to grow.
