Did you water them before you turned them out of their pots? And did you give them a massive drink after they were planted? And have you supplied them with some support so they can climb?

A picture would help us make further suggestions.

Heres the pic. I have little ladders for my peas, and mind you, the garden is VERY deep with new soil and plant food/fert. What can be happening to my peas???? Ill send a closer pic after work. The peas are in the back.

Quick insert. This garden has the same problem and the pic was readily available, practically identical.

Sometimes you have to help the pea tendrils find the fence if they are planted too far from the fence - gently lean them against the support so they will climb on their own. I've never tried to transplant peas as they are supposed to be hard to transplant. Once the peas get going, they are usually hard to stop as long as it doesn't get too hot for them. Or too dry.

Mine are nearly finished for the season in middle Georgia. This year was much colder than normal, usually I would have had to pull them up in April!

Peas don't transplant very well. Direct seed in the spring when the soil temp at two inches is 60 degrees F or more around noon. Many snap pea varieties are weak starters so don't plant in cold soil. Do not work or plant if the soil is too wet.
