You will need a wide open field for any nitro plane. You will need at least 200m clear in all directions for your first flights. It would be worthwile visiting the nearest model flying field you can find and getting someone to take the plane up for you. A nitro plane will need at least 100m for take-off/get to cruising altitude and 100m to set up your landing approach. You can't rush your landing with a nitro - it needs plenty of room and the ability to go around if your landing approach looks bad - the last thing you want to worry about is running into a tree. 


If you want to fly around the orchard, it would be best to try a foam style plane. Many are a real blast in tight spaces, with biplanes being the best  (like the Waco foam biplane), but you might want to start with a super cheapee (like the Ultra-microstick, or similar) that will turn on a dime. The E-Flite Apprentice is another possibility - it is a large trainer style plane, but has good power and control. You only need about 20m to take off and clear the nearest trees. However, you will want to start in a wide field to get the hang of the plane, particularly landings.
