How big is the total land area that you want to garden? You mention 100sqm, is that all of it? 100sqm is not really a big area. 100k baht buys a lot of decent sized plants. I have hundreds of plants and trees in my garden and I did not spend 1000B on any single plant/tree. For example, I bought palm trees 2-3 metres high for 400-600B each. Putting a garden in with very big established trees and shrubs will cost a lot but everything grows so fast here, so there's no real need to buy those big ones. If you are putting in footpaths, stone walls, a pond, gazebo or other features then the price soon rises. Talking about spending a million baht - that's a huge amount for a garden, especially if it is only 100sqm.
