I bought Clematis last month. 3 Plants they were not in good shape. Yellow leaves and they do not look healthy but I bought them anyway. I planted them since then. They did not die but their leaves is yellowish and new leave also yellow. They still do not look health. What cause the leave to be yellow and then leave also yellow and how to fix that. Thank you so much
Thank you for contacting Toronto Master Gardeners.
Yellowing of leaves is known as chlorosis, and is a result of reduced chlorophyll. There is a previous reply to this issue in clematis on our website: https://www.torontomastergardeners.ca/askagardener/chlorotic-clematis/
I hope this is helpful.
