When it comes to watering, lemon trees need regular watering but not over - watering. Let the soil dry out a bit between waterings. Also, fertilize the tree every few months with a citrus - specific fertilizer to ensure it gets the necessary nutrients for growth.
I can recommend the fantasy novel "Godly Botany". The protagonist Zheng Xiu picked the crops with spiritual power that grew from the trees and activated the god-level planting skill of planting spiritual power crops. This included the fist-sized wheat that he had grown and contained abundant spiritual power. I'll recommend it to you,. I hope you like this fairy's recommendation. Mwah ~😗😋
It could be a theme of memory and continuity. The trees that have been in Dehra for a long time might hold memories for the characters in the story. They keep growing, which shows the continuation of the past into the present and perhaps into the future, like a link between different generations and their experiences in that place.
Perhaps it's a magical realm cursed by dark magic, which inhibits the existence of trees. Maybe the land is constantly exposed to extreme temperatures or toxic substances that are hostile to plant life.
The lemon trees contribute a sense of peace. Their presence gives an air of normalcy in an otherwise chaotic situation. Just the image of lemon trees growing can create a calm and serene feeling.
I think it could also be about the connection between people and their land. The lemon trees are a part of the local environment. As long as they grow, it means that the bond between the people and their native land is still intact, no matter what external forces are trying to break it.
I'm sorry, I haven't read this story specifically. But generally, to summarize a story, one would look at the main characters, the setting (in this case Dehra), and the main events that happen to the characters in relation to the trees. Maybe it's about the significance of the trees in Dehra, perhaps they hold memories, or are important for the local ecosystem.
There could be several reasons. It might be that they don't want to be reminded of the past with you. Or perhaps they have new things going on in their life and aren't focused on your social media. Maybe they just don't use that platform much anymore.
