10 days is a long time to leave it... Is there any way a trusted friend could come over and water it for ya?
Otherwise I would move the pot to a more shaded location or put up something to give extra shade to the plant, that way it will take alot longer to use up water if its not exposed to the direct sun... And putting a tray under it with water in it will last atleast a couple of days as plants roots will soak up water through the drainage holes under the pot. Try get a deep/larger tray that will hold more water and flood it right up when you leave. Remember to check the forecast before you go aswel as you might get some rain
The only other way would be some kind of drip irrigation system or a water pump on a timer pumped from a bucket/reservoir filled with water to the pot but this probably wont be needed...
Good luck bro that plant looks very nice
