We recently Purchased a house in Peoria and have a Plum, nectarine, peach tree that need pruning. I need to know when this can be done.  Also we have a ponderosa Lemon that did not bloom until July and is still blooming with a different sizes of fruit and blooms. I haven't found much info on this type of tree. Is this normal and how can I tell if some of the yellow is ripe. I have cut a couple and they are very tart and have thick skin and look like grapefruit when it it is cut.  Also have a mexican lime that started to bloom in September and still is blooming is this normal. Last question is we have red flame and Thompson grapes. I want to prune them but don't know, when or how much to cut them back. They grew limbs out about 12 feet from the bottom of the stock to the top of the stock which is about 6 ft high. The grapes I have seen in pictures are cut up at least 4 ft from the ground and don't spread out anymore then about 4 feet.
Can you give me any info on my above questions I would really appreciate it. 
Thank you in advanced.
