بسم الله الرحمن الرحيم
(Fatwa: 445/380/L=04/1440)
(1) Seeing your mother in good state after her death is a sign that she is in good state in the grave. However, you should continue doing charity and other good deeds and send its reward to your deceased mother.
(2) It is not sunnah to plant a tree on mother’s grave.
Allah knows Best!
