My tomato plants started out healthy but as they grow out of the cages and are blooming, the tops are getting spindly and the leaves are curling up. I planted them where I had pile of horse manure all winter. They started this after some 90 degree weather. They had plenty of water and were sprayed for insects and disease. Thanks for any suggestions.
There can be a few reasons for leaf curl on tomatoes.
The hot temperatures may be a part of the issue. Uneven watering also may add to the issue.
Horse manure generally will break down in 2 to 3 months and makes great compost. You do need to look and smell to make sure. It should look like soil and not have a manure odor.
Here are a few links for you.

Been fine for years since I've been doing it. Was grandpa's for 40+ this year, a lot of green. Central NC. A lot of people around saying the same thing.
Patience. Normally if tomatoes will not ripen, it is an issue with the temperatures and time. Tomatoes need heat to ripen well and if they don't get that, they may stay green for some time. If it has been cooler than normal in your region, this is likely the reason behind the green tomatoes. However, with a little time and patience, they will eventually begin to turn color and you will be able to enjoy them. If your tomatoes are getting quite large and you are afraid they will either die or you simply cannot wait, then you can ripen them yourself.

There must be preferred and no-no's for staking tomato stalks. What is the best technique? Should plants be pre-trimmed? What is the preferable material to tie the plant to stake? Is something like Velcro a possibility? I have wooden stakes. Please provide as many "how to's" as you can. Thank you!

I like to use either 4-5 ft. wooden or metal stakes and secure the plants by using strips of pantyhose (though you can also use twine). With the hose, you don't need to worry about the ties cutting into the plant stems as they grow because they stretch.
Some of my tomato plants (as well as some other plants) are turning yellow. A couple of my tomato plants have actually died. What might be causing this?

We recently transplanted a tomato plant, and soon after the leaves all turned yellow. Also, at the same time, from the same garden center, 2 peppers are doing the same thing. Everything else is healthy. This garden center does not guarantee any plants. Thanks, for your advice. Many of the flowers I bought here have died. I will not shop here again.
Tomato plant leaves turn yellow for many different reasons. Peppers suffer from many of the same afflictions as tomatoes and most likely are turning yellow for the same reason as your tomatoes.
