Climbers

I have a wisteria vine that for 36 years did not flower, I have great patience. Last year I had flowers on it and I was thrilled. However, all the vines have taken over. What should I do?

I have trouble growing sweet peas. I soak the seeds lightly on fabric or something porous, and when they appear to be swollen, I plant them in a raised garden which faces east. But little or no joy. Help?

I have tried 3 times now to grow Wisteria in my garden with no success. My garden is very dry in the summer and is surrounded by many trees.  I would love to have this plant growing on my fences. 

I love sweet peas. What is the best fertiliser when planting and during growth? Would it be best to use liquid feed?
