The Q&A Archives: Harry Lauder Walking Stick tree

Question: My tree was planted about 1 1/2 to 2 months ago. It is about 3 feet tall. The leaves are a healthy green but they are curled to the underside. Is this normal?

Thank you so much for your time,
Bonnie Larzelere

Answer: Harry Lauder's Walking Stick was discovered growing in an English hedgerow in the mid-1800s. This deciduous, twisted stemmed shrub usually grows to just 8-10'. The species is commonly grown commercially for nut production but this cultivar usually does not produce nuts. The light green leaves turn yellow in fall. The branch form becomes quite noticeable in winter after leaf drop and provides great winter interest. Twigs are used by florists in flower arrangements. Be sure to plant in a prominent location in the landscape where it can be enjoyed.

The leaves are not usually curled so I'd look for sucking insect pests such as aphids or leaf-hoppers. Insecticidal soap is a good control measure. Spray, wait 20 minutes, then hose the residual off to avoid leaf burn.

Best wishes with your garden!
