What are the common problems with Trachycarpus?
Insects, Diseases, and Other Plant Problems: No serious insect or disease problems. They are susceptible to scale and palm aphids. Some issues of root rot may appear as well as yellowing disease and leaf spots. For a palm, it has excellent winter hardiness, but it may suffer in the coldest locations. Signs of overwatering include yellowing leaves, soft stems, and a foul smell from the soil, indicating root rot. In contrast, an underwatered palm will have crispy, browning leaf tips and dry, compacted soil. The plant may also droop when very dry.Generally, this palm species needs additional water, particularly during warm, dry summers. Keep the soil humid, but avoid overwatering, as overwatering may cause root rot. Check the top layer of the soil and provide water where necessary. You can lower the amount of water given during winter.Signs of an overwatered palm tree can include wilting or discolored fronds. Typically, an overwatered palm tree fronds will first turn yellow, and then drown. It is also possible for dark gray/brown patches that feel moist to the touch to develop on the fronds.
How do you overwinter a Trachycarpus?
Trachycarpus fortunei is frost hardy but may need winter protection in prolonged periods of cold weather – simply wrap the plant with hessian or horticultural fleece and mulch around the base with straw. Potted plants can be moved indoors. Trachycarpus fortunei performs best in part shade, but it is still happy with full sun. Planted in full sun in the ground and Trachys will grow very fast, whilst in a pot in the shade they will grow very slowly. The most important consideration is to try and choose a location for it that is protected from winter winds.
