my peas have been affected by powderly mildew, are they safe to consume if I wash them and shell them?
Mildew usually occurs at the end of the season. If they are shelled and cooked the vegetation is fine to eat. Make sure the mildew is not inside the pods however.
After most of my peas are harvested, do I take away the plant, or just leave it in the soil for a second harvest? The seed packet says to plant again in late summer, but do you take out the old plants first?
You continues harvesting until the plant stops producing pods.

I have planted peas in the same spot 3 years in a row. I had good crops the first two years but this year the plants are small and poorly colored.i had tulips in the same spot overwinter and also had poor results. Any ideas?
A soil test is a valuable test to determine the quality of your soil.
Your County Extension Office can help you with a soil test for small fee.

There can be different reasons for poor results with your plants, pest, disease, and environmental causes. Peas are a cool weather crop and if the weather is too warm, they will not generally do well.

I'm in Charlotte, and wonder whether Pea and carrot seeds will germinate when it's hot. If I wait until weather turns it may get too cold by the time the veggies are ready to pick. Last year I made plantings in mid September, and cold weather around Thanksgiving ruined my peas.

We live in Zone 7 and planted cool season seeds (peas, spinach, kale, broccoli) in raised beds during last month's warm spell. Covered the beds with plastic (not clear) before the cold snap. We see evidence that the seedlings are still growing nicely and wonder if we can uncover them tomorrow, now that the temps are better. I worry about keeping the plastic on too long. Obviously new at this! :) Please advise.
Certainly uncover the plants when temperatures warm during the day.

Can you include a photo? It could be either one of those, and I would not be able to give you a diagnosis without being able to see it. I will be more than glad to help once I have a photo for identification.
I have great luck in the garden, but planted around a hundred pea seeds and I bet only 15 came up. I forgot to apply noculent, but I always have problems with peas rain or shine. This year has been rainy, so the cooler weather should have been great.
Unfortunately, this rain is what caused the issue. Peas are very sensitive to rot, and wet conditions will cause this. A dusting of wettable sulfur, or a mix of 1/4 peroxide and 3/4 water will help to guard against this, but this will also kill an inoculate. Adding this back in after treatment will negate this.
