I am native of Pakistan, currently residing in the US, born and raised in an arid, sandy, hot climate. The area used to have lot of greenery - trees and bushes but unfortunately locals cut everything about 50 years ago and sold it in cities. Now, the area is an environmental disaster. Chickpea is the only crop grown there, the harvest season used to start in June but due this desertification the harvest time now is April. I am trying introduce some trees and bushes in the area and exploring to obtain seeds for hot weather tolerant trees and bushes. I will be grateful if someone kindly send me some sources where I can get such information - like type of plants suitable for my area and where to obtain their seeds.
