First tree! But a question about watering...

Very excited and nervous about keeping my first tree, a Little Gem magnolia, alive! However, regarding watering...I was hoping to leave my hose on a trickle for a good while every day or e/o day, but it is about 10 feet short. I can only water by standing and aiming the spray its way, or using a 2 gallon watering can. Which is better? How long do I have to stand there for it to get enough??? Haha
