    I have been to the Imperial Valley in summer, and I am impressed that you are getting anything to grow there! There are some varieties of sweet pea that are supposed to be quite heat tolerant, including the heirloom variety "Cupani". For other varieties you will just have to experiment, or perhaps try growing them in the fall/winter.

    This is common, and not really much to worry about. If you are still concerned, then you can refer to these articles: https://www.gardeningknowhow.com/ornamental/flowers/sweet-pea/

    Yes, perennial sweet peas can (and should) be cut back to prevent them from spreading too far. You can cut back in either spring or fall.

    In the areas where you don't want them growing, dig up or mow the plants, then put mulch over the area to prevent re-growth. Also, collect any seed pods that have fallen to prevent the plants from reseeding themselves and spreading.

    For the main area where you want the plant to grow, you can cut back 1/3 of the vines each year. Cut off any part of the vine that is spreading into an area where you don't want them.

    This is possible, and really the better way to do it. They don't particularly like transplanting, so if they can be planted in their terminal pot, then they will appreciate this. Just make sure to plant them 6 inches to a foot apart.

    Do not eat these!!! The leaves are only mildly toxic, luckily. This can cause severe intestinal discomfort. Please avoid this in the future!

    Sweet pea shrub requires minimal watering. If the soil is staying too wet, the roots will suffer and leaves turn yellow as a result. Imbalances in nutrients in the soil can also lead to yellowing. Potential problems are low magnesium, high potassium and low iron. A soil test to determine whether you have deficiency or toxicity of specific nutrients is important as just throwing down extra nutrients may worsen the problem. Check the website of your state's extension service to see if any diseases are in your area.
