watering a new maple

Asked November 7, 2017, 9:51 AM EST

I planted a 3" dia. sienna maple on my NE-facing lawn in Fridley in mid-August. I was advised by your service to give it plenty of water up to the time the ground froze, which shouldn't be for another month. My hoses are already too icy to supply water. I've lost a new maple to winter kill before. Should I be concerned about this? I was considering drilling a few holes in the bottom of an old 5-gallon bucket and setting it over the root ball and filling it with another bucket until the ground freezes.

You are right that it is a challenge to balance adequate watering in the fall and being mindful of the safety of your hoses and pipes. I think your idea to use a bucket with holes should be just fine for the short remainder of time that you may need to water. Between the rainfall we receive and the cooler weather reducing your tree's needs, it will likely need less water this month than earlier this fall. You can continue to test the root ball soil to see what the moisture level is and water when necessary until the ground freezes.
