Hi Vishruti, how'd you end up using this space? What'd you plant?

In high humidity, I suspect fungus but it could easily also be some kind of sucking insect. Try swabbing the plant, especially the underside of the leaves, with methylated spirits. Also spray with fungicide. By the way, don't want to say this, but in the West the word 'swastika' doesn't have good connotations. I know the meaning is totally different in the east, but using that as your avatar name might not encourage people to help.

I have two acre land. Can u suggest some practical ideas for landscaping in north indian (Delhi-NCR) scenario. I also need some grass mounds with shrubs. what type of grass to be used for lawns which require least maintenance. Suggest some flowering plants..

Aditi, Sorry to be a spoil-sport but the plan is far away from reality. Like every locality has a setback limit defined, doesn't look like that is followed. The stairs space isn't sufficient for elderly to reach the next floor. Entrance to the smaller room is like a maze and the kitchen is almost non existent. It's good to have your requirements defined but IMHO this plan is a bit too stretched. Great try, but please seek professional help on the plan. Thanks, Nitin Cornerstone Designs, Bangalore.
