We are at our calmest and happiest when we are close to nature - this is why people have gardens to get to experience this feeling on a daily basis. There are lots of garden designs but here we are looking specifically at a tropical garden. A tropical garden features tropical plants and requires good rainfall or a decent irrigation or sprinkler system for watering. These gardens typically need little fertilizer and heavy mulching. They contain plants such as banana plants, ferns, papaya trees and orchids. The lawns are reduced to a minimum and pathways are either natural flat stone or gravel. Of course you also need a great house plan to go with the garden such as this 4 bedroom all en-suite plan.
