The knots have formed because the branches have be pruned back to the same places over and over again. To remove the gnarled growth you'll need to prune below the knots. If you do this all at once you'll lose all of the leafy and flowering stems so you may need to renovate the tree over a period of years. For instance, if you cut back every third branch that has developed knots this year, then prune one-third of them back next year, and the final third the following year you'll eventually rid your tree of the disfiguring. Then, to keep the gnarled growth from developing again, selectively prune the branches in both the spring and the fall months, pruning at different lengths each time. Hope this information provides some guidance. |
