How to prune a young citrus tree
Can someone tell me how to prune a young citrus tree?? I have a 5 ft tall multigrafted citgrus tree.(Grapefruit,Meyer lemon, persian lime, 2 types of oranges. Question is how to detect suckers to prune. Some are on the trunk which I know to cut off. But some sucker type growth is on the ends and along the branches esp the grapefruit and naval orange branches. There may be as many as 8 growths come out a foot long each in a couple of days at the end of each branch. They are very soft, flat shaped and grow very quickly. Should all these be cutt off or some of them or leave them alone???? Thanks for answers!!
