Placement of wind chime

[myfs_89542]

Dear Cecil,
I am visiting your site after a long time and I like the new look - it's great.
I need your excellent advice on a number of queries. Please do advise on all - I would be most grateful.
# All of last year, I have had a 5 metal rod wind chime up in the E part of my house. It hangs in the small space behind the sliding windows. Do I have to shift it to another sector this year?
# Also, because of exposure to sun and rain, the threads holding the rods broke. So I refixed the rods and hung it up again. This is not any problem?
Please also advise on these:
# My sister loves bougainvillea plants and there are two of them in our E sector. She plans to shift one to the N part of the house. She will get irritated if I tell her not keep them, so what else can I do - keep them trimmed and small, etc.?
# I have started make organic compost for my plants at home. I keep it in the window box outside the sliding windows. This location is the E sector. Is this fine?
# I am facing a lot of illness in the house - I have stomach upsets, headaches; my father has a relapse of oedema. Do I have to check for any negative energies?
Thanks a lot
