Terrace garden issue

I live in a individual appartment with 8 houses including mine. The issue is i kept few plants which is bought from TN terrace garden kit by Tamil Nadu Horticulture office. As TN govt., is encouraging people to grow up terrace garden plants which is low in weight, water need and maintenances. I am using that only. From the first day itself the fellow owners were okay with me except 3 owners. They are keeps on targeting me in removing the plants and pressuring me to remove my plants immediately. The issue is raising after a month of my plants set-up has done. And also threatening me that they ll throw away my plants and even burn them. My plants were kept only in the corners of the terrace in a neat manner. But the 2 owners alone targetting me in the name of Common area occupation. Always targeting me in every thing I do. Ordering me everytime to remove it immediately only by giving the reason that they don't like my plants which is been there. What can I do ? Kindly, help me out with this issue.
