Valmiki Ramayana Ayodhya Kanda Sarga 63 Shloka 10

सः अहम् such me, आम्रवणम् mango trees, छित्वा cutting, पलाशान् च palasa trees, न्यषेचयम् have watered, दुर्मतिः unwise, फलागमे at the time of bearing fruit, रामम् Rama, त्यक्त्वा leaving, पश्चात् repenting, शोचामि I am grieving.

So I have cut the mango trees and watered palasa trees. In utter foolishness, I have banished Rama at the time of fruition and regretting later.
