I planted 2 rosebay rhododendrons about 10 days ago - on a slope in the shade. They are a good size - 2.5 feet tall and round. I've been watering daily. However, I need to be out of town for a week, in a few days (in August in PA) . There's no neighbor to rely on for watering. Is there a self watering system to be recommended for these? Do the plant gators I see advertised work over a week? Thank you for all suggestions.
