The Q&A Archives: contorted filbert tree

Question: our contorted filbert, 12 years old, developed problems last year, lost leaves on one side of the tree. Applied fungiside, sprayed for bugs, used a systemic cartridge in the Ross root feeder and fertilized - at a loss of what best to do. Beginning to come out a little this spring - what is needed? Should we prune off apparently dead limbs? Were told to prune only when dormant in the fall.

Answer: Whatever the original cause of the problem I think you stopped it in its tracks with the fungicide, insecticide and fertilizer applications. You can prune off anything obviously dead now in the spring. Try not to do too much pruning of live material, though because it could encourage suckers (upright stems) to grow this summer. Then in the fall, after the tree has gone dormant, you can prune to shape it. Best wishes with your contorted filbert!
